Late onset startle induced tics. (1/67)
Three cases of late onset Gilles de la Tourette's syndrome are presented. The motor tics were mainly induced by an unexpected startling stimulus, but the startle reflex was not exaggerated. The tics developed after physical trauma or a period of undue emotional stress. Reflex tics may occur in Gilles de la Tourette's syndrome, but have not been described in late onset Tourette's syndrome. Such tics must be distinguished from psychogenic myoclonus and the culture bound startle syndromes. (+info)Quantitative study of spontaneous eye blinks and eye tics in Gilles de la Tourette's syndrome. (2/67)
Spontaneous eye blink rate and frequency of eye tics were studied in nine Tourette patients during periods of rest, conversation, and video watching. In comparison with controls, the Tourette patients showed a significantly higher blink rate during rest and video watching. Conversation induced a significant increase in blink rate in the control group, but not in the Tourette patients, whereas video watching significantly increased blink rate in both groups. The frequency of eye tics showed a significant decrease during conversation and increased significantly during video watching in Tourette patients. In five patients, a significant positive correlation between blink rate and eye tic frequency was found, whereas one patient showed a significant negative correlation. Our results show that, even though some of our patients were on neuroleptic treatment, blink rate was about twofold to threefold increased versus healthy controls, suggesting increased central dopaminergic activity. Furthermore, these first quantitative data illustrate task specific effects on eye tic frequency and the complexity of their relation with eye blinks. (+info)Mercury intoxication presenting with tics. (3/67)
A 5 year old Chinese boy presented with recurrent oral ulceration followed by motor and vocal tics. The Chinese herbal spray he used for his mouth ulcers was found to have a high mercury content. His blood mercury concentration was raised. Isolated tics as the sole presentation of mercury intoxication has not previously been reported. (+info)Immediate and long term outcome after infrathalamic and thalamic lesioning for intractable Tourette's syndrome. (4/67)
OBJECTIVE: The surgical treatment of intractable Tourette's syndrome is controversial. Experience with 17 consecutive patients treated between 1970 and 1998 is reviewed and the efficacy and safety of surgical treatment is assessed. METHODS: These patients were retrospectively reclassified into subtypes according to the protocol of the Tourette's Syndrome Study Group. One patient was excluded from the study. Ventriculography based stereotactic zona incerta (ZI) and ventrolateral/ lamella medialis thalamotomy (VL/LM) were performed on all patients. The preoperative, postoperative, and late tic severities were assessed by the tic severity rating scale. The median follow up of 11 patients (65%) was 7 years (range 3.5-17 years) and six patients were lost to long term follow up. RESULTS: Median age was 23 years (range 11-40) at the time of surgery. Median duration of illness was 14 years (range 3-33). The mean preoperative motor and vocal tic severities were estimated to be 4.44 (SD 0.63) and 3.81 (SD 0.66), respectively. Unilateral ZI lesioning and VL/LM lesioning selected by asymmetry of symptoms provide an effective control of tic severity (p motor and vocal<0.001). In attenuation of contralateral symptoms, a second surgical intervention in the relevant side could reduce tic severity sufficiently (p motor<0.01; p vocal<0.005). Transient complications occurred in 68% of patients. Only one permanent complication was registered in six patients followed up after unilateral surgery. Two out of five patients followed up after bilateral surgery had disabling side effects of surgery. CONCLUSIONS: ZI and VL/LM lesioning provide a significant long term reduction of tic severity in intractable Tourette's syndrome. Adequate selection of the side of first intervention might prevent the patient from increased risk of bilateral surgery. (+info)Tics and Tourette syndrome: clinical evaluation of 44 cases. (5/67)
We evaluated 44 patients with tics and Tourette's syndrome (TS) emphasising the age of onset of symptoms, sex, classification and localization of tics, associated symptoms and signs and comorbidities. Thirty-three patients (75.2%) had TS defined criteria whereas 10 (22.7%) had chronic motor and/or vocal tics. Simple motor tics were found in 43 cases (97.7%), mainly affecting the eyes (43.2%), mouth (43.2%), face (34.1%). Simple vocal tics occurred in 33 (75%). Coprolalia was found in just 6 cases (13.6%) and copropraxia in just 2 (4.5%). Obsessive compulsive disorder and/or symptoms were found in 26 cases (59.1%) and attention deficit in 17 (38.6%). Eighteen patients (40.9%) had other disorders, such as alcoholism, tabagism, drug abuse, affective disorders, anxiety, sleep and learning disorders. The data obtained are similar to those found by other authors. We highlight the low frequency of coprolalia, as well as the associated neuropsychiatric disorders. (+info)Analyzing the influence of tic-related talk on vocal and motor tics in children with Tourette's syndrome. (6/67)
This study examined the effect of tic-related talk on the vocal and motor tics of 2 boys with Tourette's syndrome. Using ABAB withdrawal designs, the boys were alternately exposed to conditions with and without talk of their tics. For both boys, vocal tics markedly increased when talk pertained to tics and decreased when talk did not pertain to tics, but motor tic covariance was less consistent. (+info)Prevalence of tics and Tourette syndrome in an inpatient adult psychiatry setting. (7/67)
OBJECTIVE: Given the widely recognized genetic basis for Gilles de la Tourette syndrome (TS) and the suggestion that the putative TS gene(s) may be expressed as or associated with a variety of psychiatric illnesses, this study was undertaken to assess the prevalence of tics and TS in a psychiatric inpatient population. DESIGN: Cross-sectional study. SETTING AND PATIENTS: 200 consecutive adult patients who were admitted to the psychiatric wards of University College London Teaching Hospitals. OUTCOME MEASURES: TS and related behaviours, as assessed by the comprehensive semi-structured National Hospital Interview Schedule. RESULTS: None of the 200 patients had definite TS, but 2 were observed to have motor tics; 10 had a history of tics (present for less than a year), and 7 reported a family history of tics. Thus, 19 (9.5%) inpatients qualified for inclusion in a broadly defined TS diathesis. These rates are significantly lower than those reported in a similar community based epidemiological study of adolescents (p = 0.018). CONCLUSIONS: Our findings do not support the theory that TS and related behaviours are over-represented among adult inpatients with psychiatric illnesses. (+info)A transgenic model of comorbid Tourette's syndrome and obsessive-compulsive disorder circuitry. (8/67)
The tic disorder Tourette's Syndrome (TS) and obsessive-compulsive disorder (OCD) are comorbid behavioral disorders, suggesting a shared but still unknown neuronal basis. To 'circuit-test' such behaviors, we previously engineered transgenic mice expressing a neuropotentiating protein (cholera toxin A1 subunit) within a cortical-limbic subset of dopamine D1-receptor expressing (D1+) neurons known to trigger glutamatergic excitation of orbitofrontal, sensorimotor, limbic and efferent striatal circuits thought to be hyperactive or affected in OCD and TS. These mice exhibited OCD-like behaviors including generalized behavioral perseveration and compulsion-like leaping and grooming-associated pulling and biting of skin and hair. We now report that these OCD-like mice, like humans, also exhibit comorbid TS-like behaviors, including juvenile-onset tics; increased tic number, complexity and flurries; increased tic severity in males; voluntary tic suppression; and tic responsiveness to a non-cataleptic TS+OCD drug therapy (clonidine, 0.01 mg kg(-1)). These data suggest that hormonal gender differences, apart from the influence of genetic or autoimmune etiologic factors, may be sufficient to aggravate tic severity in human TS males compared to TS females. These data also proffer a precise neuronal basis for TS+OCD, wherein tics and primary compulsions or obsessions are evoked by hyperactivity of various cortical-limbic projection neurons' glutamatergic output to efferent targets like the striatum. The 'Cortical-limbic Glutamatergic Neuron' (CGN) neuronal circuit model merges formerly opposed neurotransmitter models of TS and OCD, and is consistent with new clinical reports of increased cortical hyperactivity, striatal glutamate and striatal inhibitory D2 receptors, and reduced striatal responsiveness, in these disorders. (+info)A tic is a sudden, repetitive, involuntary movement or vocalization that occurs frequently. Tics can be simple, involving only one muscle group, or complex, involving several muscle groups or coordinated patterns of movements. Common motor tics include eye blinking, facial grimacing, and shoulder shrugging, while common vocal tics include throat clearing, sniffing, and grunting.
Tics can vary in severity and frequency over time, and they may be exacerbated by stress, anxiety, or fatigue. In some cases, tics may be suppressible for brief periods of time, but this can lead to a buildup of tension that eventually results in an explosive release of the tic.
Tourette syndrome is a neurological disorder characterized by the presence of both motor and vocal tics that persist for more than one year. However, tics can also occur as a symptom of other medical conditions, such as Huntington's disease, Wilson's disease, or certain infections. In some cases, tics may be caused by medication side effects or substance abuse.
Tourette Syndrome (TS) is a neurological disorder characterized by the presence of multiple motor tics and at least one vocal (phonic) tic. These tics are sudden, repetitive, rapid, involuntary movements or sounds that occur for more than a year and are not due to substance use or other medical conditions. The symptoms typically start before the age of 18, with the average onset around 6-7 years old.
The severity, frequency, and types of tics can vary greatly among individuals with TS and may change over time. Common motor tics include eye blinking, facial grimacing, shoulder shrugging, and head or limb jerking. Vocal tics can range from simple sounds like throat clearing, coughing, or barking to more complex phrases or words.
In some cases, TS may be accompanied by co-occurring conditions such as attention deficit hyperactivity disorder (ADHD), obsessive-compulsive disorder (OCD), anxiety, and depression. These associated symptoms can sometimes have a greater impact on daily functioning than the tics themselves.
The exact cause of Tourette Syndrome remains unclear, but it is believed to involve genetic factors and abnormalities in certain brain regions involved in movement control and inhibition. There is currently no cure for TS, but various treatments, including behavioral therapy and medications, can help manage the symptoms and improve quality of life.
Obsessive-Compulsive Disorder (OCD) is a mental health disorder characterized by the presence of obsessions and compulsions. Obsessions are recurrent and persistent thoughts, urges, or images that are intrusive, unwanted, and often distressing. Compulsions are repetitive behaviors or mental acts that an individual feels driven to perform in response to an obsession or according to rigid rules, and which are aimed at preventing or reducing anxiety or distress, or preventing some dreaded event or situation. These obsessions and/or compulsions cause significant distress, take up a lot of time (an hour or more a day), and interfere with the individual's daily life, including social activities, relationships, and work or school performance. OCD is considered a type of anxiety disorder and can also co-occur with other mental health conditions.
I'm sorry for any confusion, but "peas" is not a term typically used in medical definitions. Peas are a type of legume that is commonly consumed as a vegetable. They are rich in nutrients such as protein, fiber, vitamin C, and vitamin K. If you have any questions about the health benefits or potential risks of consuming peas, I would be happy to try to help with that.
Chloroplasts are specialized organelles found in the cells of green plants, algae, and some protists. They are responsible for carrying out photosynthesis, which is the process by which these organisms convert light energy from the sun into chemical energy in the form of organic compounds, such as glucose.
Chloroplasts contain the pigment chlorophyll, which absorbs light energy from the sun. They also contain a system of membranes and enzymes that convert carbon dioxide and water into glucose and oxygen through a series of chemical reactions known as the Calvin cycle. This process not only provides energy for the organism but also releases oxygen as a byproduct, which is essential for the survival of most life forms on Earth.
Chloroplasts are believed to have originated from ancient cyanobacteria that were engulfed by early eukaryotic cells and eventually became integrated into their host's cellular machinery through a process called endosymbiosis. Over time, chloroplasts evolved to become an essential component of plant and algal cells, contributing to their ability to carry out photosynthesis and thrive in a wide range of environments.
Trigeminal neuralgia is a chronic pain condition that affects the trigeminal nerve, which is one of the largest nerves in the head. It carries sensations from the face to the brain.
Medically, trigeminal neuralgia is defined as a neuropathic disorder characterized by episodes of intense, stabbing, electric shock-like pain in the areas of the face supplied by the trigeminal nerve (the ophthalmic, maxillary, and mandibular divisions). The pain can be triggered by simple activities such as talking, eating, brushing teeth, or even touching the face lightly.
The condition is more common in women over 50, but it can occur at any age and in either gender. While the exact cause of trigeminal neuralgia is not always known, it can sometimes be related to pressure on the trigeminal nerve from a nearby blood vessel or other causes such as multiple sclerosis. Treatment typically involves medications, surgery, or a combination of both.
Chloroplasts are organelles found in the cells of plants, algae, and some protists. They are responsible for carrying out photosynthesis, which is the process by which these organisms convert light energy into chemical energy. Chloroplast proteins are the various proteins that are located within the chloroplasts and play a crucial role in the process of photosynthesis.
Chloroplasts contain several types of proteins, including:
1. Structural proteins: These proteins help to maintain the structure and integrity of the chloroplast.
2. Photosynthetic proteins: These are involved in capturing light energy and converting it into chemical energy during photosynthesis. They include proteins such as photosystem I, photosystem II, cytochrome b6f complex, and ATP synthase.
3. Regulatory proteins: These proteins help to regulate the various processes that occur within the chloroplast, including gene expression, protein synthesis, and energy metabolism.
4. Metabolic proteins: These proteins are involved in various metabolic pathways within the chloroplast, such as carbon fixation, amino acid synthesis, and lipid metabolism.
5. Protective proteins: These proteins help to protect the chloroplast from damage caused by reactive oxygen species (ROS) that are produced during photosynthesis.
Overall, chloroplast proteins play a critical role in maintaining the health and function of chloroplasts, and by extension, the overall health and survival of plants and other organisms that contain them.
Dexmethylphenidate is a central nervous system (CNS) stimulant primarily used to treat attention deficit hyperactivity disorder (ADHD). It is the active ingredient in several brand-name medications, including Focalin and Focalin XR. Dexmethylphenidate is the d-enantiomer of methylphenidate, which means it is a more potent form of the drug than racemic methylphenidate (which contains both the d- and l-enantiomers in equal proportions).
Dexmethylphenidate works by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain. This can help improve focus, attention, and reduce impulsivity and hyperactivity in people with ADHD. Dexmethylphenidate is available in immediate-release (Focalin) and extended-release (Focalin XR) formulations, which differ in how quickly they release the active ingredient into the body.
Like all medications, dexmethylphenidate can have side effects, including appetite loss, stomach ache, headache, insomnia, and irritability. It is important to follow your doctor's instructions carefully when taking this medication and to report any bothersome or persistent side effects promptly. Dexmethylphenidate may also interact with other medications, so it is important to inform your doctor of all the medications you are taking before starting dexmethylphenidate.
Neoplastic stem cells, also known as cancer stem cells (CSCs), are a subpopulation of cells within a tumor that are capable of self-renewal and generating the heterogeneous lineages of cells that comprise the tumor. These cells are believed to be responsible for the initiation, maintenance, and progression of cancer, as well as its recurrence and resistance to therapy.
CSCs share some similarities with normal stem cells, such as their ability to divide asymmetrically and give rise to differentiated progeny. However, they also have distinct characteristics that distinguish them from their normal counterparts, including aberrant gene expression, altered signaling pathways, and increased resistance to apoptosis (programmed cell death).
The existence of CSCs has important implications for cancer diagnosis, treatment, and prevention. Targeting these cells specifically may be necessary to achieve durable remissions and prevent relapse, as they are thought to survive conventional therapies that target the bulk of the tumor. Further research is needed to better understand the biology of CSCs and develop effective strategies for their elimination.
Obsessive behavior is defined in the medical context as repetitive, persistent, and intrusive thoughts, images, or urges that cause distress or anxiety. These obsessions are not simply excessive worries about real-life problems, but rather they are irrational and uncontrollable. Often, individuals with obsessive behavior attempt to ignore or suppress their obsessions, which can lead to increased distress and anxiety. In some cases, the obsessions may become so overwhelming that they interfere with a person's daily life and ability to function.
Obsessive behavior is a key feature of several mental health conditions, including obsessive-compulsive disorder (OCD), body dysmorphic disorder (BDD), and hoarding disorder. In these conditions, the obsessions are often accompanied by compulsive behaviors that are performed in an attempt to alleviate the anxiety or distress caused by the obsessions.
It is important to note that everyone experiences unwanted thoughts or urges from time to time. However, when these thoughts become so frequent and distressing that they interfere with a person's daily life, it may be indicative of an underlying mental health condition. In such cases, it is recommended to seek professional help from a qualified mental health provider.
Attention Deficit Hyperactivity Disorder (ADHD) with hyperactivity is a neurodevelopmental disorder that affects both children and adults. The condition is characterized by symptoms including:
1. Difficulty paying attention or staying focused on a single task
2. Impulsivity, or acting without thinking
3. Hyperactivity, or excessive fidgeting, restlessness, or talking
In order to be diagnosed with ADHD with hyperactivity, an individual must exhibit these symptoms to a degree that is developmentally inappropriate and interferes with their daily functioning. Additionally, the symptoms must have been present for at least six months and be present in multiple settings (e.g., at home, school, work).
It's important to note that ADHD can manifest differently in different people, and some individuals may experience predominantly inattentive or impulsive symptoms rather than hyperactive ones. However, when the hyperactive component is prominent, it is referred to as ADHD with hyperactivity.
Effective treatments for ADHD with hyperactivity include a combination of medication (such as stimulants) and behavioral therapy. With appropriate treatment, individuals with ADHD can learn to manage their symptoms and lead successful, fulfilling lives.
Compulsive behavior is a type of repetitive behavior that an individual feels driven to perform, despite its negative impact on their daily life and mental health. It is often driven by an overwhelming urge or anxiety, and the person may experience distress if they are unable to carry out the behavior. Compulsive behaviors can be associated with various psychiatric conditions, including obsessive-compulsive disorder (OCD), body dysmorphic disorder, eating disorders, and impulse control disorders.
Examples of compulsive behaviors include:
1. Excessive handwashing or cleaning
2. Repeatedly checking locks, light switches, or appliances
3. Ordering or arranging items in a specific way
4. Compulsive hoarding
5. Compulsive shopping or spending
6. Compulsive eating or purging behaviors (such as those seen in bulimia nervosa)
7. Compulsive sexual behavior (sex addiction)
8. Compulsive exercise
9. Compulsive hair pulling (trichotillomania)
10. Compulsive skin picking (excoriation disorder)
Treatment for compulsive behaviors typically involves a combination of medication, psychotherapy (such as cognitive-behavioral therapy), and lifestyle changes to help manage the underlying causes and reduce the urge to engage in the compulsive behavior.
The basal ganglia are a group of interconnected nuclei, or clusters of neurons, located in the base of the brain. They play a crucial role in regulating motor function, cognition, and emotion. The main components of the basal ganglia include the striatum (made up of the caudate nucleus, putamen, and ventral striatum), globus pallidus (divided into external and internal segments), subthalamic nucleus, and substantia nigra (with its pars compacta and pars reticulata).
The basal ganglia receive input from various regions of the cerebral cortex and other brain areas. They process this information and send output back to the thalamus and cortex, helping to modulate and coordinate movement. The basal ganglia also contribute to higher cognitive functions such as learning, decision-making, and habit formation. Dysfunction in the basal ganglia can lead to neurological disorders like Parkinson's disease, Huntington's disease, and dystonia.
In the context of medical terminology, a "habit" refers to a regular, repeated behavior or practice that is often performed automatically or subconsciously. Habits can be physical (such as biting nails) or mental (such as worrying). They can be harmless, beneficial (like regularly brushing your teeth), or harmful (like smoking cigarettes).
Habits are different from instincts or reflexes because they involve a learned behavior that has been repeated and reinforced over time. Breaking a habit can often be challenging due to the deeply ingrained nature of the behavior.
Medication adherence, also known as medication compliance, refers to the degree or extent of conformity to a treatment regimen as prescribed by a healthcare provider. This includes taking medications at the right time, in the correct dosage, and for the designated duration. Poor medication adherence can lead to worsening health conditions, increased hospitalizations, and higher healthcare costs.
Medication errors refer to preventable events that may cause or lead to inappropriate medication use or patient harm, while the medication is in the control of the healthcare professional, patient, or consumer. Such events may be related to professional practice, health care products, procedures, and systems, including prescribing; order communication; product labeling, packaging, and nomenclature; compounding; dispensing; distribution; administration; education; monitoring; and use.
Medication errors can occur at any stage of the medication process, including ordering, transcribing, dispensing, administering, and monitoring. They can result from various factors such as poor communication, lack of knowledge, distractions, confusing drug names or labels, and inadequate systems for preventing errors. Medication errors can lead to adverse drug events, which can cause patient harm, including temporary or permanent disability, and even death.
Methylphenidate is a central nervous system (CNS) stimulant drug that is primarily used in the treatment of attention deficit hyperactivity disorder (ADHD) and narcolepsy. It works by increasing the levels of neurotransmitters, such as dopamine and norepinephrine, in the brain, which helps to improve focus, concentration, and alertness.
Methylphenidate is available under various brand names, including Ritalin, Concerta, and Methylin, among others. It comes in different forms, such as tablets, capsules, or extended-release formulations, and is typically taken orally. The dosage and duration of treatment are usually individualized based on the patient's response to the medication and any potential side effects.
It is important to note that methylphenidate has a high potential for abuse and addiction, and its use should be closely monitored by a healthcare professional. Additionally, it can interact with other medications and medical conditions, so it is essential to inform your doctor of any health concerns before starting treatment with methylphenidate.
Central nervous system (CNS) stimulants are a class of drugs that increase alertness, attention, energy, and/or mood by directly acting on the brain. They can be prescribed to treat medical conditions such as narcolepsy, attention deficit hyperactivity disorder (ADHD), and depression that has not responded to other treatments.
Examples of CNS stimulants include amphetamine (Adderall), methylphenidate (Ritalin, Concerta), and modafinil (Provigil). These medications work by increasing the levels of certain neurotransmitters, such as dopamine and norepinephrine, in the brain.
In addition to their therapeutic uses, CNS stimulants are also sometimes misused for non-medical reasons, such as to enhance cognitive performance or to get high. However, it's important to note that misusing these drugs can lead to serious health consequences, including addiction, cardiovascular problems, and mental health issues.
