Subjectively experienced sensations in the absence of an appropriate stimulus, but which are regarded by the individual as real. They may be of organic origin or associated with MENTAL DISORDERS.
A false belief regarding the self or persons or objects outside the self that persists despite the facts, and is not considered tenable by one's associates.
A common condition characterized by transient partial or total paralysis of skeletal muscles and areflexia that occurs upon awakening from sleep or less often while falling asleep. Stimuli such as touch or sound may terminate the episode, which usually has a duration of seconds to minutes. This condition may occur in normal subjects or be associated with NARCOLEPSY; CATAPLEXY; and hypnagogic HALLUCINATIONS. The pathophysiology of this condition is closely related to the normal hypotonia that occur during REM sleep. (From Adv Neurol 1995;67:245-271)
Psychotic organic mental disorders resulting from the toxic effect of drugs and chemicals or other harmful substance.
A severe emotional disorder of psychotic depth characteristically marked by a retreat from reality with delusion formation, HALLUCINATIONS, emotional disharmony, and regressive behavior.
Disorders in which there is a loss of ego boundaries or a gross impairment in reality testing with delusions or prominent hallucinations. (From DSM-IV, 1994)
A chronic form of schizophrenia characterized primarily by the presence of persecutory or grandiose delusions, often associated with hallucination.
Study of mental processes and behavior of schizophrenics.
Acquired or developmental cognitive disorders of AUDITORY PERCEPTION characterized by a reduced ability to perceive information contained in auditory stimuli despite intact auditory pathways. Affected individuals have difficulty with speech perception, sound localization, and comprehending the meaning of inflections of speech.
A neurodegenerative disease characterized by dementia, mild parkinsonism, and fluctuations in attention and alertness. The neuropsychiatric manifestations tend to precede the onset of bradykinesia, MUSCLE RIGIDITY, and other extrapyramidal signs. DELUSIONS and visual HALLUCINATIONS are relatively frequent in this condition. Histologic examination reveals LEWY BODIES in the CEREBRAL CORTEX and BRAIN STEM. SENILE PLAQUES and other pathologic features characteristic of ALZHEIMER DISEASE may also be present. (From Neurology 1997;48:376-380; Neurology 1996;47:1113-1124)
Chronic mental disorders in which there has been an insidious development of a permanent and unshakeable delusional system (persecutory delusions or delusions of jealousy), accompanied by preservation of clear and orderly thinking. Emotional responses and behavior are consistent with the delusional state.
A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism. (Adams et al., Principles of Neurology, 6th ed, p1059, pp1067-75)
Lower lateral part of the cerebral hemisphere responsible for auditory, olfactory, and semantic processing. It is located inferior to the lateral fissure and anterior to the OCCIPITAL LOBE.
An obsolete concept, historically used for childhood mental disorders thought to be a form of schizophrenia. It was in earlier versions of DSM but is now included within the broad concept of PERVASIVE DEVELOPMENT DISORDERS.
Loss of the power to comprehend written materials despite preservation of the ability to write (i.e., alexia without agraphia). This condition is generally attributed to lesions that "disconnect" the visual cortex of the non-dominant hemisphere from language centers in the dominant hemisphere. This may occur when a dominant visual cortex injury is combined with underlying white matter lesions that involve crossing fibers from the occipital lobe of the opposite hemisphere. (From Adams et al., Principles of Neurology, 6th ed, p483)
Intracytoplasmic, eosinophilic, round to elongated inclusions found in vacuoles of injured or fragmented neurons. The presence of Lewy bodies is the histological marker of the degenerative changes in LEWY BODY DISEASE and PARKINSON DISEASE but they may be seen in other neurological conditions. They are typically found in the substantia nigra and locus coeruleus but they are also seen in the basal forebrain, hypothalamic nuclei, and neocortex.
Posterior portion of the CEREBRAL HEMISPHERES responsible for processing visual sensory information. It is located posterior to the parieto-occipital sulcus and extends to the preoccipital notch.
Hallucinogenic alkaloid isolated from the flowering heads (peyote) of Lophophora (formerly Anhalonium) williamsii, a Mexican cactus used in Indian religious rites and as an experimental psychotomimetic. Among its cellular effects are agonist actions at some types of serotonin receptors. It has no accepted therapeutic uses although it is legal for religious use by members of the Native American Church.
The artificial language of schizophrenic patients - neologisms (words of the patient's own making with new meanings).
Drugs designed and synthesized, often for illegal street use, by modification of existing drug structures (e.g., amphetamines). Of special interest are MPTP (a reverse ester of meperidine), MDA (3,4-methylenedioxyamphetamine), and MDMA (3,4-methylenedioxymethamphetamine). Many drugs act on the aminergic system, the physiologically active biogenic amines.

A personality disorder characterized by overly reactive and intensely expressed or overly dramatic behavior, proneness to exaggeration, emotional excitability, and disturbances in interpersonal relationships.
A condition characterized by recurrent episodes of daytime somnolence and lapses in consciousness (microsomnias) that may be associated with automatic behaviors and AMNESIA. CATAPLEXY; SLEEP PARALYSIS, and hypnagogic HALLUCINATIONS frequently accompany narcolepsy. The pathophysiology of this disorder includes sleep-onset rapid eye movement (REM) sleep, which normally follows stage III or IV sleep. (From Neurology 1998 Feb;50(2 Suppl 1):S2-S7)
A condition characterized by transient weakness or paralysis of somatic musculature triggered by an emotional stimulus or physical exertion. Cataplexy is frequently associated with NARCOLEPSY. During a cataplectic attack, there is a marked reduction in muscle tone similar to the normal physiologic hypotonia that accompanies rapid eye movement sleep (SLEEP, REM). (From Adams et al., Principles of Neurology, 6th ed, p396)
Agents that control agitated psychotic behavior, alleviate acute psychotic states, reduce psychotic symptoms, and exert a quieting effect. They are used in SCHIZOPHRENIA; senile dementia; transient psychosis following surgery; or MYOCARDIAL INFARCTION; etc. These drugs are often referred to as neuroleptics alluding to the tendency to produce neurological side effects, but not all antipsychotics are likely to produce such effects. Many of these drugs may also be effective against nausea, emesis, and pruritus.
Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.

Disturbances in mental processes related to learning, thinking, reasoning, and judgment.
Lack of correspondence between the way a stimulus is commonly perceived and the way an individual perceives it under given conditions.

Activation of Heschl's gyrus during auditory hallucinations. (1/533)

Apart from being a common feature of mental illness, auditory hallucinations provide an intriguing model for the study of internally generated sensory perceptions that are attributed to external sources. Until now, the knowledge about the cortical network that supports such hallucinations has been restricted by methodological limitations. Here, we describe an experiment with paranoid schizophrenic patients whose on- and offset of auditory hallucinations could be monitored within one functional magnetic resonance imaging (fMRI) session. We demonstrate an increase of the blood oxygen level-dependent (BOLD) signal in Heschl's gyrus during the patients' hallucinations. Our results provide direct evidence of the involvement of primary auditory areas in auditory verbal hallucinations and establish novel constraints for psychopathological models.  (+info)

Elementary visual hallucinations, blindness, and headache in idiopathic occipital epilepsy: differentiation from migraine. (2/533)

This is a qualitative and chronological analysis of ictal and postictal symptoms, frequency of seizures, family history, response to treatment, and prognosis in nine patients with idiopathic occipital epilepsy and visual seizures. Ictal elementary visual hallucinations are stereotyped for each patient, usually lasting for seconds. They consist of mainly multiple, bright coloured, small circular spots, circles, or balls. Mostly, they appear in a temporal hemifield often moving contralaterally or in the centre where they may be flashing. They may multiply and increase in size in the course of the seizure and may progress to other non-visual occipital seizure symptoms and more rarely to extra-occipital manifestations and convulsions. Blindness occurs usually from the beginning and postictal headache, often indistinguishable from migraine, is common. It is concluded that elementary visual hallucinations in occipital seizures are entirely different from visual aura of migraine when individual elements of colour, shape, size, location, movement, speed of development, duration, and progress are synthesised together. Postictal headache does not show preference for those with a family history of migraine. Most of the patients are misdiagnosed as having migraine with aura, basilar migraine, acephalgic migraine, or migralepsy simply because physicians are not properly informed of differential diagnostic criteria. As a result, treatment may be delayed for years. Response to carbamazepine is excellent and seizures may remit.  (+info)

Cognitive disorders: A question of misattribution. (3/533)

A recent study indicates that schizophrenia patients are prone to auditory hallucinations because they have difficulty recognising their 'inner speech' as their own, and consequently tend to misattribute it to an external source.  (+info)

The perceptual consequences of visual loss: 'positive' pathologies of vision. (4/533)

Fifty patients with visual hallucinations and illusions secondary to degenerative eye disease reported remarkably stereotyped experiences. Questionnaire responses revealed five previously recognized categories of pathological vision (perseveration, illusory visual spread, polyopia, prosopometamorphopsia and micro/macropsia) and three novel categories (tessellopsia, hyperchromatopsia and dendropsia). Identical pathologies of vision occur in a range of clinical and experimental settings, suggesting that they reflect fundamental visual processes. The known neurophysiology of the visual cortex helps explain the phenomenology of the experiences and provides the basis for a neurobiologically based classification of positive and negative visual perceptual disorders.  (+info)

Hypercalcemia in an euthyroid patient with secondary hypoadrenalism and diabetes insipidus due to hypothalamic tumor. (5/533)

A 20-year-old Japanese man with a hypothalamic tumor (most likely germ-cell tumor) which caused secondary hypoadrenalism, hypogonadism and diabetes insipidus developed hypercalcemia and acute renal failure. The serum levels of intact PTH (iPTH), PTH-related protein (PTH-rP), 1,25-dihydroxy vitamin D (1,25- (OH)2 D), ACTH, cortisol, gonadotropins and testosterone were decreased, but his serum levels of triiodothyronine (T3) and thyroxine (T4) were within the normal range at admission, with depressed TSH and slightly increased thyroglobulin. The hypercalcemia was refractory to extensive hydration and calcitonin, but was ameliorated by pamidronate. After irradiation of the hypothalamic tumor, panhypopituitarism gradually developed. The patient has been normocalcemic for the last 2 years and is doing well under replacement therapy with glucocorticoid, L-thyroxine, methyltestosterone and 1-desamino D arginine vasopressin (dDAVP). As to the mechanism of euthyroidism at admission, transient destructive thyroiditis associated with hypopituitarism or delayed development of hypothyroidism following the hypoadrenalism was suggested. This is the first reported case of hypercalcemia in secondary hypoadrenalism due to hypothalamic tumor. Hypercalcemia was most likely induced by increased bone resorption, which was probably elicited by the combined effects of deficient glucocorticoid and sufficient thyroid hormones in addition to hypovolemia and reduced renal calcium excretion. Furthermore, severe dehydration due to diabetes insipidus and disturbance of thirst sensation caused by the hypothalamic tumor aggravated the hypercalcemia, leading to acute renal failure.  (+info)

When the left brain is not right the right brain may be left: report of personal experience of occipital hemianopia. (6/533)

OBJECTIVES: To make a personal report of a hemianopia due to an occipital infarct, sustained by a professor of neurology. METHODS: Verbatim observation of neurological phenomena recorded during the acute illness. RESULTS: Hemianopia, visual hallucinations, and non-occipital deficits without extraoccipital lesions on MRI, are described and discussed. CONCLUSIONS: Hemianopia, due to an occipital infarct, without alexia, is not a disability which precludes a normal professional career. Neurorehabilitation has not been necessary.  (+info)

Validity and usefulness of the Wisconsin Manual for Assessing Psychotic-like Experiences. (7/533)

The Wisconsin Manual for Assessing Psychotic-like Experiences is an interview-based assessment system for rating psychotic and psychotic-like symptoms on a continuum of deviancy from normal to grossly psychotic. The original manual contained six scales, assessing thought transmission, passivity experiences, thought withdrawal, auditory experiences, personally relevant aberrant beliefs, and visual experiences. A seventh scale assessing deviant olfactory experiences was subsequently added. The rating scales have good interrater reliability when used by trained raters. Cross-sectional studies indicated that the frequency and deviancy of psychotic-like experiences are elevated among college students who were identified, hypothetically, as psychosis prone by other criteria. Psychotic-like experiences of moderate deviancy in college students successfully predicted the development of psychotic illness and poorer overall adjustment 10 years later. The manual is useful for identifying psychosis-prone individuals and is recommended for use in linkage and treatment outcome studies. The present article provides an interview schedule for collecting information required for rating psychotic-like experiences.  (+info)

Acute psychotic symptoms induced by topiramate. (8/533)

The incidence of psychosis during clinical trials of topiramate was 0.8%, not significantly different from the rate for placebo or reported rates of psychosis in patients with refractory epilepsy. We observed psychotic symptoms in five patients soon after initiation of topiramate therapy. We performed a retrospective chart review of the first 80 patients who began on topiramate after approval for clinical use, between January and April 1997. Symptoms suggestive of psychosis, including hallucinations and delusions, were sought for analysis. Cognitive effects such as psychomotor slowing, confusion, and somnolence were not included. Five patients developed definite psychotic symptoms 2 to 46 days after beginning topiramate. Dosages at symptom onset were 50-400 mg/day. Symptoms included paranoid delusions in four patients and auditory hallucinations in three. Symptoms of psychosis and other psychiatric symptoms resolved quickly with discontinuation of topiramate in three patients, dose reduction from 300 to 200 mg/day in one and with inpatient treatment and neuroleptics in another. One patient had a history of auditory hallucinations, one of aggressive and suicidal thoughts, but three had no significant psychiatric history. Physicians should be aware of the possibility of psychotic symptoms, even in patients without a previous psychiatric history, when prescribing topiramate. Symptoms resolve quickly with discontinuation.  (+info)

A hallucination is a perception in the absence of external stimuli. They are sensory experiences that feel real, but are generated from inside the mind rather than by external reality. Hallucinations can occur in any of the senses, causing individuals to hear sounds, see visions, or smell odors that aren't actually present. They can range from relatively simple experiences, such as seeing flashes of light, to complex experiences like seeing and interacting with people or objects that aren't there. Hallucinations are often associated with certain medical conditions, mental health disorders, or the use of certain substances.

A delusion is a fixed, false belief that is firmly held despite evidence to the contrary and is not shared by others who hold similar cultural or religious beliefs. Delusions are a key symptom of certain psychiatric disorders, such as schizophrenia and delusional disorder. They can also be seen in other medical conditions, such as dementia, brain injury, or substance abuse.

Delusions can take many forms, but some common types include:

* Persecutory delusions: the belief that one is being targeted or harmed by others
* Grandiose delusions: the belief that one has special powers, talents, or importance
* Erotomanic delusions: the belief that someone, often of higher social status, is in love with the individual
* Somatic delusions: the belief that one's body is abnormal or has been altered in some way
* Religious or spiritual delusions: the belief that one has a special relationship with a deity or religious figure

Delusions should not be confused with overvalued ideas, which are strongly held beliefs based on subjective interpretation of experiences or evidence. Overvalued ideas may be shared by others and can sometimes develop into delusions if they become fixed and firmly held despite contradictory evidence.

Sleep paralysis is a temporary inability to move or speak while falling asleep or waking up, often accompanied by frightening hallucinations. These episodes typically last a few seconds to several minutes. During sleep paralysis, a person's body is immobile and cannot perform voluntary muscle movements even though they are fully conscious and awake. This condition can be quite alarming, but it is generally harmless and does not pose any serious threat to one's health. Sleep paralysis is often associated with certain sleep disorders, such as narcolepsy, or other medical conditions, as well as stress, lack of sleep, and changes in sleep patterns.

Substance-induced psychosis is a type of psychosis that is caused by the use of drugs, alcohol, or other substances. The American Psychiatric Association's Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defines substance/medication-induced psychotic disorder as follows:

A. Presence of one (or more) of the following symptoms:

1. Delusions.
2. Hallucinations.
3. Disorganized speech (e.g., frequent derailment or incoherence).

B. There is evidence from the history, physical examination, or laboratory findings that the disturbance is caused by the direct physiological effects of a substance (e.g., a drug of abuse, a medication) or a combination of substances.

C. The disturbance does not occur exclusively during the course of a delirium and is not better explained by a psychotic disorder that is not substance/medication-induced. The symptoms in Criterion A developed during or soon after substance intoxication or withdrawal, or after exposure to a medication.

D. The disturbance causes significant distress or impairment in social, occupational, or other important areas of functioning.

E. The disturbance is not better accounted for by another mental disorder (e.g., major depressive disorder, bipolar disorder).

It's important to note that the diagnosis of substance-induced psychosis requires a thorough medical and psychiatric evaluation to determine if the symptoms are caused by substance use or another underlying mental health condition.

Schizophrenia is a severe mental disorder characterized by disturbances in thought, perception, emotion, and behavior. It often includes hallucinations (usually hearing voices), delusions, paranoia, and disorganized speech and behavior. The onset of symptoms typically occurs in late adolescence or early adulthood. Schizophrenia is a complex, chronic condition that requires ongoing treatment and management. It significantly impairs social and occupational functioning, and it's often associated with reduced life expectancy due to comorbid medical conditions. The exact causes of schizophrenia are not fully understood, but research suggests that genetic, environmental, and neurodevelopmental factors play a role in its development.

Psychotic disorders are a group of severe mental health conditions characterized by distorted perceptions, thoughts, and emotions that lead to an inability to recognize reality. The two most common symptoms of psychotic disorders are hallucinations and delusions. Hallucinations are when a person sees, hears, or feels things that aren't there, while delusions are fixed, false beliefs that are not based on reality.

Other symptoms may include disorganized speech, disorganized behavior, catatonic behavior, and negative symptoms such as apathy and lack of emotional expression. Schizophrenia is the most well-known psychotic disorder, but other types include schizoaffective disorder, delusional disorder, brief psychotic disorder, shared psychotic disorder, and substance-induced psychotic disorder.

Psychotic disorders can be caused by a variety of factors, including genetics, brain chemistry imbalances, trauma, and substance abuse. Treatment typically involves a combination of medication, therapy, and support services to help manage symptoms and improve quality of life.

Paranoid Schizophrenia is a subtype of Schizophrenia, which is a chronic and severe mental disorder. It is characterized by the presence of prominent delusions and auditory hallucinations. The delusions in paranoid schizophrenia often involve themes of persecution or grandiosity. Individuals with this subtype usually have a clear sense of self and maintain relatively well-preserved cognitive functions and affect. However, their symptoms can significantly impact their ability to function in daily life, social relationships, and vocational activities. It's important to note that schizophrenia is a complex disorder, and its diagnosis should be made by a qualified mental health professional based on a comprehensive evaluation of the individual's symptoms, history, and mental status examination.

I must clarify that there is no such thing as "Schizophrenic Psychology." The term schizophrenia is used to describe a specific and serious mental disorder that affects how a person thinks, feels, and behaves. It's important not to use the term casually or inaccurately, as it can perpetuate stigma and misunderstanding about the condition.

Schizophrenia is characterized by symptoms such as hallucinations (hearing or seeing things that aren't there), delusions (false beliefs that are not based on reality), disorganized speech, and grossly disorganized or catatonic behavior. These symptoms can impair a person's ability to function in daily life, maintain relationships, and experience emotions appropriately.

If you have any questions related to mental health conditions or psychology, I would be happy to provide accurate information and definitions.

Auditory perceptual disorders, also known as auditory processing disorders (APD), refer to a group of hearing-related problems in which the ears are able to hear sounds normally, but the brain has difficulty interpreting or making sense of those sounds. This means that individuals with APD have difficulty recognizing and discriminating speech sounds, especially in noisy environments. They may also have trouble identifying where sounds are coming from, distinguishing between similar sounds, and understanding spoken language when it is rapid or complex.

APD can lead to difficulties in academic performance, communication, and social interactions. It is important to note that APD is not a hearing loss, but rather a problem with how the brain processes auditory information. Diagnosis of APD typically involves a series of tests administered by an audiologist, and treatment may include specialized therapy and/or assistive listening devices.

Lewy body disease, also known as dementia with Lewy bodies, is a type of progressive degenerative dementia that affects thinking, behavior, and movement. It's named after Dr. Friedrich Lewy, the scientist who discovered the abnormal protein deposits, called Lewy bodies, that are characteristic of this disease.

Lewy bodies are made up of a protein called alpha-synuclein and are found in the brain cells of individuals with Lewy body disease. These abnormal protein deposits are also found in people with Parkinson's disease, but they are more widespread in Lewy body disease, affecting multiple areas of the brain.

The symptoms of Lewy body disease can vary from person to person, but they often include:

* Cognitive decline, such as memory loss, confusion, and difficulty with problem-solving
* Visual hallucinations and delusions
* Parkinsonian symptoms, such as stiffness, tremors, and difficulty walking or moving
* Fluctuations in alertness and attention
* REM sleep behavior disorder, where a person acts out their dreams during sleep

Lewy body disease is a progressive condition, which means that the symptoms get worse over time. Currently, there is no cure for Lewy body disease, but medications can help manage some of the symptoms.

Paranoid disorders are a category of mental disorders characterized by the presence of paranoia, which is defined as a persistent and unfounded distrust or suspicion of others. This can include beliefs that others are trying to harm you, deceive you, or are plotting against you. These beliefs are not based in reality and are firmly held despite evidence to the contrary.

The Diagnostic and Statistical Manual of Mental Disorders (DSM-5), which is used by mental health professionals to diagnose mental conditions, includes two paranoid disorders: Delusional Disorder and Paranoid Personality Disorder.

Delusional disorder is characterized by the presence of one or more delusions for a month or longer, with no significant hallucinations, disorganized speech, or grossly disorganized or catatonic behavior. The individual's functioning is not markedly impaired and behavior is not obviously odd or bizarre.

Paranoid personality disorder is characterized by a pervasive distrust and suspiciousness of others such that their motives are interpreted as malevolent, beginning in early adulthood and present in a variety of contexts. The individual may appear cold and aloof or may be explosively angry if they feel threatened.

It's important to note that these disorders can cause significant distress and impairment in social, occupational, and other areas of functioning. If you or someone you know is experiencing symptoms of a paranoid disorder, it's important to seek help from a qualified mental health professional.

Parkinson's disease is a progressive neurodegenerative disorder that affects movement. It is characterized by the death of dopamine-producing cells in the brain, specifically in an area called the substantia nigra. The loss of these cells leads to a decrease in dopamine levels, which results in the motor symptoms associated with Parkinson's disease. These symptoms can include tremors at rest, stiffness or rigidity of the limbs and trunk, bradykinesia (slowness of movement), and postural instability (impaired balance and coordination). In addition to these motor symptoms, non-motor symptoms such as cognitive impairment, depression, anxiety, and sleep disturbances are also common in people with Parkinson's disease. The exact cause of Parkinson's disease is unknown, but it is thought to be a combination of genetic and environmental factors. There is currently no cure for Parkinson's disease, but medications and therapies can help manage the symptoms and improve quality of life.

The temporal lobe is one of the four main lobes of the cerebral cortex in the brain, located on each side of the head roughly level with the ears. It plays a major role in auditory processing, memory, and emotion. The temporal lobe contains several key structures including the primary auditory cortex, which is responsible for analyzing sounds, and the hippocampus, which is crucial for forming new memories. Damage to the temporal lobe can result in various neurological symptoms such as hearing loss, memory impairment, and changes in emotional behavior.

Childhood-onset schizophrenia is a rare and severe form of schizophrenia that begins before the age of 13. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) defines it as a disorder characterized by the presence of at least two active symptom categories (delusions, hallucinations, disorganized speech, grossly disorganized or catatonic behavior, or negative symptoms) for a significant portion of time during a 1-month period (with some symptoms persisting for at least 6 months).

The onset of schizophrenia in children can be insidious and may present with subtle changes in behavior, social interactions, and emotional expression. Symptoms may include:

* Delusions: False beliefs that are not based on reality and are firmly held despite evidence to the contrary.
* Hallucinations: Perception of stimuli without an external source, such as hearing voices or seeing things that are not there.
* Disorganized speech: Incoherent or irrelevant speech, frequent derailment, or inability to maintain a conversation.
* Grossly disorganized or catatonic behavior: Marked impairment in personal hygiene, self-care, and interpersonal relationships, or unusual motor behaviors such as rigidity, stupor, or agitation.
* Negative symptoms: Reduced emotional expression, avolition (lack of motivation), alogia (poverty of speech), or anhedonia (inability to feel pleasure).

Childhood-onset schizophrenia can have a profound impact on a child's development, academic performance, and social relationships. Early identification and intervention are crucial for improving outcomes and reducing the risk of long-term disability. Treatment typically involves a combination of antipsychotic medication, psychotherapy, and supportive services to address the complex needs of children with this disorder.

Alexia, also known as word blindness or pure alexia, is a type of acquired reading disorder that affects the ability to recognize and understand written words, despite having intact intelligence, speech, and language comprehension. It is typically caused by damage to specific areas in the left occipitotemporal cortex of the brain, often as a result of stroke or head injury.

People with pure alexia may have difficulty reading individual words, even those they know well, but can still write and speak normally. They may use strategies such as guessing words based on their first letter or shape, or by using context clues to help them understand written text. Treatment for pure alexia typically involves various forms of rehabilitation and compensatory strategies to help individuals regain or improve their reading abilities.

Lewy bodies are abnormal aggregates of alpha-synuclein protein that develop in nerve cells (neurons) in the brain. They are named after Frederick Lewy, a German-American neurologist who discovered them while working with Dr. Alois Alzheimer. The presence of Lewy bodies is a hallmark feature of Lewy body dementia, which includes both Parkinson's disease dementia and dementia with Lewy bodies.

Lewy bodies can lead to the dysfunction and death of neurons in areas of the brain that control movement, cognition, and behavior. This can result in a range of symptoms, including motor impairments, cognitive decline, visual hallucinations, and mood changes. The exact role of Lewy bodies in the development and progression of these disorders is not fully understood, but they are believed to contribute to the neurodegenerative process that underlies these conditions.

The occipital lobe is the portion of the cerebral cortex that lies at the back of the brain (posteriorly) and is primarily involved in visual processing. It contains areas that are responsible for the interpretation and integration of visual stimuli, including color, form, movement, and recognition of objects. The occipital lobe is divided into several regions, such as the primary visual cortex (V1), secondary visual cortex (V2 to V5), and the visual association cortex, which work together to process different aspects of visual information. Damage to the occipital lobe can lead to various visual deficits, including blindness or partial loss of vision, known as a visual field cut.

Mescaline is a naturally occurring psychoactive alkaloid that is found in several species of cacti, including the peyote (Lophophora williamsii), San Pedro (Echinopsis pachanoi), and Peruvian torch (Echinopsis peruviana) cacti. It is known for its ability to produce profound changes in consciousness, mood, and perception when ingested.

In a medical context, mescaline is classified as a hallucinogen or psychedelic drug. It works by binding to serotonin receptors in the brain, which leads to altered states of consciousness, including visual hallucinations, distorted perceptions of time and space, and altered emotional states.

It's important to note that while mescaline has been used for centuries in religious and spiritual practices among indigenous communities, its use is not without risks. High doses can lead to unpleasant or even dangerous psychological effects, such as anxiety, panic, and psychosis. Additionally, the legal status of mescaline varies by country and region, so it's important to be aware of local laws and regulations before using it.

'Schizophrenic language' is not a formal medical term, but the concept refers to the unusual and often disturbed patterns of speech that can be observed in individuals with schizophrenia. These language abnormalities are considered one of the positive symptoms of schizophrenia and can include:

1. **Word Salad (Incoherent Speech)**: This is when a person's speech becomes disorganized, fragmented, and lacks logical or understandable connections between words, phrases, or sentences. It may seem like the individual is randomly stringing together words without any clear meaning.

2. **Neologisms (Made-Up Words)**: These are new words or phrases that have been invented by the individual. They may be understandable only to the person using them.

3. **Tangentiality (Straying Off Topic)**: This is when a person's responses are indirect and unrelated to the topic being discussed, although they may start off on topic. The speaker may stray further and further from the original point until they are no longer discussing it at all.

4. **Perseveration (Persistent Repetition)**: This is when a person repeats certain words, phrases, or ideas over and over again, even when they are not relevant to the conversation.

5. **Illogical Thinking/Conclusions**: A person's thoughts may not follow a logical sequence, leading to illogical conclusions or statements that do not make sense in the context of the conversation.

6. **Thought Disorder**: This is a broader term that includes various disturbances in thinking and thought processes, which can then manifest as abnormalities in speech.

It's important to note that these symptoms can vary widely from person to person, and not everyone with schizophrenia will experience all of them. Furthermore, these symptoms should be evaluated and diagnosed by a qualified mental health professional.

Designer drugs are synthetic or chemically altered substances that are designed to mimic the effects of controlled substances. They are often created in clandestine laboratories and marketed as legal alternatives to illegal drugs. These drugs are called "designer" because they are intentionally modified to avoid detection and regulation by law enforcement agencies and regulatory bodies.

Designer drugs can be extremely dangerous, as their chemical composition is often unknown or only partially understood. They may contain potentially harmful impurities or variations that can lead to unpredictable and sometimes severe health consequences. Examples of designer drugs include synthetic cannabinoids (such as "Spice" or "K2"), synthetic cathinones (such as "bath salts"), and novel psychoactive substances (NPS).

It is important to note that while some designer drugs may be legal at the time they are manufactured and sold, their possession and use may still be illegal under federal or state laws. Additionally, many designer drugs have been made illegal through scheduling by the Drug Enforcement Administration (DEA) or through legislation specifically targeting them.

Parapsychology is not a term that has a medical definition per se, as it is not a field that is recognized by mainstream medicine. It is an interdisciplinary field that studies the nature of psychic phenomena, including telepathy, clairvoyance, precognition, psychokinesis, near-death experiences, and reincarnation.

Parapsychology is often considered a branch of psychology, but it is not universally accepted as a legitimate field of study by the scientific community. Many scientists and skeptics argue that there is little empirical evidence to support the existence of psychic phenomena, and that parapsychological research lacks rigor and is prone to bias and methodological flaws.

Nonetheless, some researchers continue to investigate these phenomena using controlled experiments and statistical analyses, with the goal of better understanding the nature of consciousness and its relationship to the physical world.

Psychiatric Status Rating Scales are standardized assessment tools used by mental health professionals to evaluate and rate the severity of a person's psychiatric symptoms and functioning. These scales provide a systematic and structured approach to measuring various aspects of an individual's mental health, such as mood, anxiety, psychosis, behavior, and cognitive abilities.

The purpose of using Psychiatric Status Rating Scales is to:

1. Assess the severity and improvement of psychiatric symptoms over time.
2. Aid in diagnostic decision-making and treatment planning.
3. Monitor treatment response and adjust interventions accordingly.
4. Facilitate communication among mental health professionals about a patient's status.
5. Provide an objective basis for research and epidemiological studies.

Examples of Psychiatric Status Rating Scales include:

1. Clinical Global Impression (CGI): A brief, subjective rating scale that measures overall illness severity, treatment response, and improvement.
2. Positive and Negative Syndrome Scale (PANSS): A comprehensive scale used to assess the symptoms of psychosis, including positive, negative, and general psychopathology domains.
3. Hamilton Rating Scale for Depression (HRSD) or Montgomery-Ă…sberg Depression Rating Scale (MADRS): Scales used to evaluate the severity of depressive symptoms.
4. Young Mania Rating Scale (YMRS): A scale used to assess the severity of manic or hypomanic symptoms.
5. Brief Psychiatric Rating Scale (BPRS) or Symptom Checklist-90 Revised (SCL-90-R): Scales that measure a broad range of psychiatric symptoms and psychopathology.
6. Global Assessment of Functioning (GAF): A scale used to rate an individual's overall psychological, social, and occupational functioning on a hypothetical continuum of mental health-illness.

It is important to note that Psychiatric Status Rating Scales should be administered by trained mental health professionals to ensure accurate and reliable results.

Dreams are a series of thoughts, images, and sensations occurring in a person's mind during sleep. They can be vivid or vague, positive or negative, and may involve memories, emotions, and fears. The scientific study of dreams is called oneirology. While the exact purpose and function of dreams remain a topic of debate among researchers, some theories suggest that dreaming may help with memory consolidation, problem-solving, emotional processing, and learning.

Dreams usually occur during the rapid eye movement (REM) stage of sleep, although they can also happen in non-REM stages. They are typically associated with complex brain activities, involving areas such as the amygdala, hippocampus, and the neocortex. The content of dreams can be influenced by various factors, including a person's thoughts, experiences, emotions, physical state, and environmental conditions.

It is important to note that dreaming is a natural and universal human experience, and understanding dreams can provide insights into our cognitive processes, emotional well-being, and mental health.

Psilocybin is defined as a naturally occurring psychedelic compound found in certain species of mushrooms, also known as "magic mushrooms." It is classified as a tryptamine and is structurally similar to the neurotransmitter serotonin. When ingested, psilocybin is converted into psilocin, which acts as a serotonin receptor agonist in the brain, leading to altered consciousness, perception, and thought. Its effects can vary widely depending on the individual, the dose, and the setting in which it is taken.

Histrionic Personality Disorder (HPD) is a mental health condition, as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), published by the American Psychiatric Association.

It's characterized by a pattern of excessive emotionality and attention-seeking behavior, beginning in early adulthood and present in various contexts. Individuals with HPD may exhibit rapidly shifting and exaggerated emotions, seductive or provocative behavior, and an excessive need for approval. They may also be uncomfortable when not the center of attention.

Please note that only a qualified healthcare professional can diagnose mental health conditions. If you or someone else has symptoms of Histrionic Personality Disorder, it's important to seek professional help.

Narcolepsy is a chronic neurological disorder that affects the control of sleep and wakefulness. It's characterized by excessive daytime sleepiness (EDS), where people experience sudden, uncontrollable episodes of falling asleep during the day. These "sleep attacks" can occur at any time - while working, talking, eating, or even driving.

In addition to EDS, narcolepsy often includes cataplexy, a condition that causes loss of muscle tone, leading to weakness and sometimes collapse, often triggered by strong emotions like laughter or surprise. Other common symptoms are sleep paralysis (a temporary inability to move or speak while falling asleep or waking up), vivid hallucinations during the transitions between sleep and wakefulness, and fragmented nighttime sleep.

The exact cause of narcolepsy is not fully understood, but it's believed to involve genetic and environmental factors, as well as problems with certain neurotransmitters in the brain, such as hypocretin/orexin, which regulate sleep-wake cycles. Narcolepsy can significantly impact a person's quality of life, making it essential to seek medical attention for proper diagnosis and management.

Cataplexy is a medical condition characterized by sudden and temporary loss of muscle tone or strength, typically triggered by strong emotions such as laughter, anger, or surprise. This can result in symptoms ranging from a slight slackening of the muscles to complete collapse. Cataplexy is often associated with narcolepsy, which is a neurological disorder that affects sleep-wake cycles. It's important to note that cataplexy is different from syncope (fainting), as it specifically involves muscle weakness rather than loss of consciousness.

Antipsychotic agents are a class of medications used to manage and treat psychosis, which includes symptoms such as delusions, hallucinations, paranoia, disordered thought processes, and agitated behavior. These drugs work by blocking the action of dopamine, a neurotransmitter in the brain that is believed to play a role in the development of psychotic symptoms. Antipsychotics can be broadly divided into two categories: first-generation antipsychotics (also known as typical antipsychotics) and second-generation antipsychotics (also known as atypical antipsychotics).

First-generation antipsychotics, such as chlorpromazine, haloperidol, and fluphenazine, were developed in the 1950s and have been widely used for several decades. They are generally effective in reducing positive symptoms of psychosis (such as hallucinations and delusions) but can cause significant side effects, including extrapyramidal symptoms (EPS), such as rigidity, tremors, and involuntary movements, as well as weight gain, sedation, and orthostatic hypotension.

Second-generation antipsychotics, such as clozapine, risperidone, olanzapine, quetiapine, and aripiprazole, were developed more recently and are considered to have a more favorable side effect profile than first-generation antipsychotics. They are generally effective in reducing both positive and negative symptoms of psychosis (such as apathy, anhedonia, and social withdrawal) and cause fewer EPS. However, they can still cause significant weight gain, metabolic disturbances, and sedation.

Antipsychotic agents are used to treat various psychiatric disorders, including schizophrenia, bipolar disorder, major depressive disorder with psychotic features, delusional disorder, and other conditions that involve psychosis or agitation. They can be administered orally, intramuscularly, or via long-acting injectable formulations. The choice of antipsychotic agent depends on the individual patient's needs, preferences, and response to treatment, as well as the potential for side effects. Regular monitoring of patients taking antipsychotics is essential to ensure their safety and effectiveness.

Medical Definition:

Magnetic Resonance Imaging (MRI) is a non-invasive diagnostic imaging technique that uses a strong magnetic field and radio waves to create detailed cross-sectional or three-dimensional images of the internal structures of the body. The patient lies within a large, cylindrical magnet, and the scanner detects changes in the direction of the magnetic field caused by protons in the body. These changes are then converted into detailed images that help medical professionals to diagnose and monitor various medical conditions, such as tumors, injuries, or diseases affecting the brain, spinal cord, heart, blood vessels, joints, and other internal organs. MRI does not use radiation like computed tomography (CT) scans.

Phenylcarbamates are a group of organic compounds that contain a phenyl group (a functional group consisting of a six-carbon ring, with the formula -C6H5) bonded to a carbamate group (-NHCOO-). Carbamates are compounds that contain a carbonyl (>C=O) group bonded to a nitrogen atom that is also bonded to two organic substituents.

In the medical field, phenylcarbamates have been used as drugs for various purposes. For example, some phenylcarbamates have been used as anticonvulsants, while others have been investigated for their potential as anti-cancer agents. However, it is important to note that many phenylcarbamates also have toxic properties and must be used with caution.

One well-known example of a phenylcarbamate is phenytoin, an anticonvulsant medication used to treat seizures. Phenytoin works by slowing down the transmission of nerve impulses in the brain, which can help prevent or reduce the severity of seizures.

It's worth noting that while phenylcarbamates have been studied for their potential therapeutic uses, they are not a widely used class of drugs and further research is needed to fully understand their mechanisms of action and potential side effects.

Cognitive disorders are a category of mental health disorders that primarily affect cognitive abilities including learning, memory, perception, and problem-solving. These disorders can be caused by various factors such as brain injury, degenerative diseases, infection, substance abuse, or developmental disabilities. Examples of cognitive disorders include dementia, amnesia, delirium, and intellectual disability. It's important to note that the specific definition and diagnostic criteria for cognitive disorders may vary depending on the medical source or classification system being used.

Perceptual distortion is not explicitly defined within the realm of medicine, but it does fall under the broader category of cognitive impairments and abnormalities. It generally refers to the incorrect interpretation or misrepresentation of sensory information by the brain. This can result in various experiences such as hallucinations, illusions, or distorted perceptions of reality. Perceptual distortions are often associated with certain medical conditions like mental disorders (e.g., schizophrenia, bipolar disorder), neurological disorders (e.g., migraines, epilepsy), and substance use disorders.

SAN FRANCISCO (AP) - Dustin Moskovitz is plotting an escape from email.

Moskovitz is trying to turn that chronic headache into an afterthought with Asana, a San Francisco startup he runs with former Facebook and Google product manager, Justin Rosenstein.
