A cognitive disorder characterized by an impaired ability to comprehend written and printed words or phrases despite intact vision. This condition may be developmental or acquired. Developmental dyslexia is marked by reading achievement that falls substantially below that expected given the individual's chronological age, measured intelligence, and age-appropriate education. The disturbance in reading significantly interferes with academic achievement or with activities of daily living that require reading skills. (From DSM-IV)

Unidirectional dyslexia in a polyglot. (1/545)

Alexia is usually seen after ischaemic insults to the dominant parietal lobe. A patient is described with a particular alexia to reading Hebrew (right to left), whereas no alexia was noted when reading in English. This deficit evolved after a hypertensive right occipitoparietal intracerebral haemorrhage, and resolved gradually over the ensuing year as the haematoma was resorbed. The deficit suggests the existence of a separate, language associated, neuronal network within the right hemisphere important to different language reading modes.  (+info)

Cortical auditory signal processing in poor readers. (2/545)

Magnetoencephalographic responses recorded from auditory cortex evoked by brief and rapidly successive stimuli differed between adults with poor vs. good reading abilities in four important ways. First, the response amplitude evoked by short-duration acoustic stimuli was stronger in the post-stimulus time range of 150-200 ms in poor readers than in normal readers. Second, response amplitude to rapidly successive and brief stimuli that were identical or that differed significantly in frequency were substantially weaker in poor readers compared with controls, for interstimulus intervals of 100 or 200 ms, but not for an interstimulus interval of 500 ms. Third, this neurological deficit closely paralleled subjects' ability to distinguish between and to reconstruct the order of presentation of those stimulus sequences. Fourth, the average distributed response coherence evoked by rapidly successive stimuli was significantly weaker in the beta- and gamma-band frequency ranges (20-60 Hz) in poor readers, compared with controls. These results provide direct electrophysiological evidence supporting the hypothesis that reading disabilities are correlated with the abnormal neural representation of brief and rapidly successive sensory inputs, manifested in this study at the entry level of the cortical auditory/aural speech representational system(s).  (+info)

Spatio-temporal contrast sensitivity, coherent motion, and visible persistence in developmental dyslexia. (3/545)

Three experiments measured spatio-temporal contrast sensitivity, coherent motion, and visible persistence in a single group of children with developmental dyslexia and a matched control group. The findings were consistent with a transient channel disorder in the dyslexic group which showed a reduction in contrast sensitivity at low spatial frequencies, a significant reduction in sensitivity for coherent motion, and a significantly longer duration of visible persistence. The results were also examined by classifying the dyslexic group into dyseidetic, dysphonetic, and mixed (dysphoneidetic) subgroups. There were no differences between the control and dyseidetic groups in contrast sensitivity, in coherent motion and in visible persistence. In comparison to the control group, the mixed (dysphoneidetic) dyslexic subgroup was found to have a significant reduction in contrast sensitivity at low spatial frequencies, a significant reduction in sensitivity for coherent motion, and a significantly longer duration of visible persistence. In comparison to the control group, the dysphonetic group only showed a reduction in contrast sensitivity at low spatial frequencies. Comparisons between the dyseidetic, dysphonetic and mixed dyslexic subgroups showed that there were no substantive differences in contrast sensitivity, coherent motion, and visible persistence. The results support the proposal and findings by Borsting et al. (Borsting E, Ridder WH, Dudeck K, Kelley C, Matsui L, Motoyama J. Vis Res 1996;36:1047-1053) that a transient channel disorder may only be present in a dysphoneidetic dyslexic subgroup. Psychometric assessment revealed that all the children with dyslexia appear to have a concurrent disorder in phonological coding, temporal order processing, and short-term memory.  (+info)

Auditory stream segregation in dyslexic adults. (4/545)

Developmental dyslexia is often associated with problems in phonological processing based on, or accompanied by, deficits in the perception of rapid auditory changes. Thirteen dyslexic adults and 18 control subjects were tested on sequences of alternating tones of high (1000 Hz) and low (400 Hz) pitch, which at short stimulus onset asynchronies (SOAs) led to perceptual separation of the sound sequence into high- and low-pitched streams. The control subjects perceived the tone sequence as connected down to SOAs of 130 ms, with segregation of the streams at shorter SOAs; in dyslexic subjects the segregation occurred already at 210 ms. Auditory stream segregation has previously been shown to impair the detection of phoneme order in segments of speech sounds. The observed aberrant segregation of sound streams in dyslexic subjects might thus contribute to their difficulties in achieving awareness of phonemes or phoneme order and in the acquisition of literacy.  (+info)

Dissociation of normal feature analysis and deficient processing of letter-strings in dyslexic adults. (5/545)

Neuroimaging studies have revealed that the functional organization of reading differs between developmentally dyslexic and non-impaired individuals. However, it is not clear how early in the reading process the differences between fluent and dyslexic readers start to emerge. We studied cortical activity of ten dyslexic adults using magnetoencephalography (MEG), as they silently read words or viewed symbol-strings which were clearly visible or degraded with Gaussian noise. This method has previously been used to dissociate between analysis of local features and pre-lexical word processing in fluent adult readers. Signals peaking around 100 ms after stimulus onset and originating in the postero-medial extrastriate cortex were associated with increasing local luminance contrast in the noise patches. These early visual responses were similar in dyslexic and non-impaired readers. In contrast, the letter-string-specific responses peaking around 150 ms predominantly in the left inferior occipito-temporal cortex in fluent readers were undetectable in dyslexic readers. Thus, while the early visual processing seems intact in dyslexic adults, the pattern of cortical activation starts to differ from that of fluent readers at the point where letter-string-specific signals first emerge during reading.  (+info)

Explicit and implicit processing of words and pseudowords by adult developmental dyslexics: A search for Wernicke's Wortschatz? (6/545)

Two groups of male university students who had been diagnosed as dyslexic when younger, and two groups of control subjects of similar age and IQ to the dyslexics, were scanned whilst reading aloud and during a task where reading was implicit. The dyslexics performed less well than their peers on a range of literacy tasks and were strikingly impaired on phonological tasks. In the reading aloud experiment, simple words and pseudowords were presented at a slow pace so that reading accuracy was equal for dyslexics and controls. Relative to rest, both normal and dyslexic groups activated the same peri- and extra-sylvian regions of the left hemisphere that are known to be involved in reading. However, the dyslexic readers showed less activation than controls in the left posterior inferior temporal cortex [Brodmann area (BA) 37, or Wernicke's Wortschatz], left cerebellum, left thalamus and medial extrastriate cortex. In the implicit reading experiment, word and pseudoword processing was contrasted to visually matched false fonts while subjects performed a feature detection paradigm. The dyslexic readers showed reduced activation in BA 37 relative to normals suggesting that this group difference, seen in both experiments, resides in highly automated aspects of the reading process. Since BA 37 has been implicated previously in modality-independent naming, the reduced activation may indicate a specific impairment in lexical retrieval. Interestingly, during the reading aloud experiment only, there was increased activation for the dyslexics relative to the controls in a pre-motor region of Broca's area (BA 6/44). We attribute this result to the enforced use of an effortful compensatory strategy involving sublexical assembly of articulatory routines. The results confirm previous findings that dyslexic readers process written stimuli atypically, based on abnormal functioning of the left hemisphere reading system. More specifically, we localize this deficit to the neural system underlying lexical retrieval.  (+info)

A new gene (DYX3) for dyslexia is located on chromosome 2. (7/545)

Developmental dyslexia is a specific reading disability affecting children and adults who otherwise possess normal intelligence, cognitive skills, and adequate schooling. Difficulties in spelling and reading may persist through adult life. Possible localisations of genes for dyslexia have been reported on chromosomes 15 (DYX1), 6p21.3-23 (DYX2), and 1p over the last 15 years. Only the localisation to 6p21.3-23 has been clearly confirmed and a genome search has not previously been carried out. We have investigated a large Norwegian family in which dyslexia is inherited as an autosomal dominant trait. A genome wide search for linkage with an average 20 cM marker density was initiated in 36 of the 80 family members. The linkage analysis was performed under three different diagnostic models. Linkage analysis in the family identified a region in 2p15-p16 which cosegregated with dyslexia. Maximum lod scores of 3.54, 2.92, and 4.32 for the three different diagnostic models were obtained. These results were confirmed by a non-parametric multipoint GENEHUNTER analysis in which the most likely placement of the gene was in a 4 cM interval between markers D2S2352 and D2S1337. Localisation of a gene for dyslexia to 2p15-16, together with the confirmed linkage to 6p21.3-23, constitute strong evidence for genetic heterogeneity in dyslexia. Since no gene for dyslexia has been isolated, little is known about the molecular processes involved. The isolation and molecular characterisation of this newly reported gene on chromosome 2 (DYX3) and DYX1 will thus provide new and exciting insights into the processes involved in reading and spelling.  (+info)

A problem with auditory processing? (8/545)

Recent studies have found associations between auditory processing deficits and language disorders such as dyslexia; but whether the former cause the latter, or simply co-occur with them, is still an open question.  (+info)

Dyslexia is a neurodevelopmental disorder that impairs an individual's ability to read, write, and spell, despite having normal intelligence and adequate education. It is characterized by difficulties with accurate and fluent word recognition, poor decoding and spelling abilities, and often accompanied by problems with reading comprehension and reduced reading experience. Dyslexia is not a result of low intelligence, lack of motivation, or poor instruction, but rather a specific learning disability that affects the way the brain processes written language. It is typically diagnosed in children, although it can go unnoticed until adulthood, and there are effective interventions and accommodations to help individuals with dyslexia overcome their challenges and achieve academic and professional success.

Acquired dyslexia, also known as "alexia" or "word blindness," is a medical condition that affects an individual's ability to understand written language despite having normal intelligence and education. It is characterized by a sudden loss of the ability to read, following damage to specific areas of the brain responsible for visual processing and language comprehension, such as the left occipitotemporal cortex.

Unlike developmental dyslexia, which is present from birth or early childhood, acquired dyslexia occurs later in life due to brain injury, stroke, infection, tumor, or other neurological conditions that damage the language and visual processing areas of the brain. Individuals with acquired dyslexia may have difficulty recognizing words, letters, or symbols, despite having intact hearing and speaking abilities.

Treatment for acquired dyslexia typically involves rehabilitation and compensation strategies to help the individual regain their reading skills or develop alternative ways to process written language. Speech-language therapy, occupational therapy, and assistive technology may be used as part of a comprehensive treatment plan.

I'm sorry for any confusion, but "reading" is not a term that has a specific medical definition. Reading is the activity or process of deciphering and understanding written words or text. It is a fundamental skill in language acquisition and communication, and is not typically used in a medical context unless there is a concern related to reading difficulties or disorders, such as dyslexia. If you have any questions related to medical terminology or health concerns, I'd be happy to try to help answer those for you!

Articulation disorders are speech sound disorders that involve difficulties producing sounds correctly and forming clear, understandable speech. These disorders can affect the way sounds are produced, the order in which they're pronounced, or both. Articulation disorders can be developmental, occurring as a child learns to speak, or acquired, resulting from injury, illness, or disease.

People with articulation disorders may have trouble pronouncing specific sounds (e.g., lisping), omitting sounds, substituting one sound for another, or distorting sounds. These issues can make it difficult for others to understand their speech and can lead to frustration, social difficulties, and communication challenges in daily life.

Speech-language pathologists typically diagnose and treat articulation disorders using various techniques, including auditory discrimination exercises, phonetic placement activities, and oral-motor exercises to improve muscle strength and control. Early intervention is essential for optimal treatment outcomes and to minimize the potential impact on a child's academic, social, and emotional development.

Phonetics is not typically considered a medical term, but rather a branch of linguistics that deals with the sounds of human speech. It involves the study of how these sounds are produced, transmitted, and received, as well as how they are used to convey meaning in different languages. However, there can be some overlap between phonetics and certain areas of medical research, such as speech-language pathology or audiology, which may study the production, perception, and disorders of speech sounds for diagnostic or therapeutic purposes.

A language test is not a medical term per se, but it is commonly used in the field of speech-language pathology, which is a medical discipline. A language test, in this context, refers to an assessment tool used by speech-language pathologists to evaluate an individual's language abilities. These tests typically measure various aspects of language, including vocabulary, grammar, syntax, semantics, and pragmatics.

Language tests can be standardized or non-standardized and may be administered individually or in a group setting. The results of these tests help speech-language pathologists diagnose language disorders, develop treatment plans, and monitor progress over time. It is important to note that language testing should be conducted by a qualified professional who has experience in administering and interpreting language assessments.

Agraphia is a neurological disorder that affects the ability to write, either by hand or through mechanical means like typing. It is often caused by damage to specific areas of the brain involved in language and writing skills, such as the left parietal lobe. Agraphia can manifest as difficulty with spelling, forming letters or words, organizing thoughts on paper, or expressing ideas in writing. Depending on the severity and location of the brain injury, agraphia may occur in isolation or alongside other language or cognitive impairments.

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.

"Remedial teaching" is not a term that has a specific medical definition. However, it is a term commonly used in the field of education to refer to specialized instruction or tutoring designed to help students who are experiencing difficulties in mastering certain skills or concepts. This type of teaching is often provided in addition to regular classroom instruction and may be individualized or small group in nature. The goal of remedial teaching is to bring the student's skill level up to par with their peers, so that they can succeed in the regular education curriculum.

It is important to note that while remedial teaching is not a medical term, it can be used as an intervention for students who have learning difficulties or disabilities, which may be identified through a psychoeducational assessment conducted by a school psychologist or other qualified professional. In some cases, remedial teaching may be recommended as part of a student's Individualized Education Program (IEP) or 504 plan, which are documents that outline the accommodations and services that students with disabilities are entitled to receive in order to ensure their access to a free and appropriate education.

The term "nervous system physiological processes" refers to the various functional activities and mechanisms that occur within the nervous system, which is responsible for controlling and coordinating bodily functions. These processes include:

1. Electrical impulse transmission: The nervous system transmits electrical signals called action potentials through neurons to transmit information between different parts of the body.
2. Neurotransmitter release and reception: Neurons communicate with each other and with other cells by releasing neurotransmitters, which are chemical messengers that bind to receptors on target cells.
3. Sensory perception: Specialized sensory neurons detect changes in the external environment (e.g., light, sound, temperature, touch) or internal environment (e.g., blood pressure, pH, glucose levels) and transmit this information to the brain for processing.
4. Motor control: The nervous system controls voluntary and involuntary movements by sending signals from the brain to muscles and glands.
5. Homeostasis: The nervous system helps maintain internal homeostasis by regulating vital functions such as heart rate, respiratory rate, body temperature, and fluid balance.
6. Cognition: The nervous system is involved in higher cognitive functions such as learning, memory, attention, perception, and language.
7. Emotional regulation: The nervous system plays a crucial role in emotional processing and regulation through its connections with the limbic system and hypothalamus.
8. Sleep-wake cycle: The nervous system regulates the sleep-wake cycle through the interaction of various neurotransmitters and brain regions.

These physiological processes are essential for normal bodily function and are tightly regulated to ensure optimal performance. Dysfunction in any aspect of the nervous system can lead to a wide range of neurological and psychiatric disorders.

Language disorders, also known as communication disorders, refer to a group of conditions that affect an individual's ability to understand or produce spoken, written, or other symbolic language. These disorders can be receptive (difficulty understanding language), expressive (difficulty producing language), or mixed (a combination of both).

Language disorders can manifest as difficulties with grammar, vocabulary, sentence structure, and coherence in communication. They can also affect social communication skills such as taking turns in conversation, understanding nonverbal cues, and interpreting tone of voice.

Language disorders can be developmental, meaning they are present from birth or early childhood, or acquired, meaning they develop later in life due to injury, illness, or trauma. Examples of acquired language disorders include aphasia, which can result from stroke or brain injury, and dysarthria, which can result from neurological conditions affecting speech muscles.

Language disorders can have significant impacts on an individual's academic, social, and vocational functioning, making it important to diagnose and treat them as early as possible. Treatment typically involves speech-language therapy to help individuals develop and improve their language skills.

Speech perception is the process by which the brain interprets and understands spoken language. It involves recognizing and discriminating speech sounds (phonemes), organizing them into words, and attaching meaning to those words in order to comprehend spoken language. This process requires the integration of auditory information with prior knowledge and context. Factors such as hearing ability, cognitive function, and language experience can all impact speech perception.

Dichotic listening tests are a type of psychological and neurological assessment that measures the ability to process two different auditory stimuli presented simultaneously to each ear. In these tests, different speech sounds, tones, or other sounds are played at the same time, one to each ear, through headphones. The participant is then asked to repeat or identify the stimuli heard in each ear.

The test is designed to evaluate the functioning of the brain's hemispheres and their specialization for processing different types of information. Typically, the right ear is more efficient at sending information to the left hemisphere, which is specialized for language processing in most people. Therefore, speech sounds presented to the right ear are often identified more accurately than those presented to the left ear.

Dichotic listening tests can be used in various fields, including neuropsychology, audiology, and cognitive science, to assess brain function, laterality, attention, memory, and language processing abilities. These tests can also help identify any neurological impairments or deficits caused by injuries, diseases, or developmental disorders.

A learning disorder is a neurodevelopmental disorder that affects an individual's ability to acquire, process, and use information in one or more academic areas despite normal intelligence and adequate instruction. It can manifest as difficulties with reading (dyslexia), writing (dysgraphia), mathematics (dyscalculia), or other academic skills. Learning disorders are not the result of low intelligence, lack of motivation, or environmental factors alone, but rather reflect a significant discrepancy between an individual's cognitive abilities and their academic achievement. They can significantly impact a person's ability to perform in school, at work, and in daily life, making it important to diagnose and manage these disorders effectively.

I'm sorry for any confusion, but "handwriting" is not a term that has a specific medical definition. Handwriting refers to the personal style or manner in which a person writes by hand. It can vary from person to person and can be influenced by factors such as an individual's fine motor skills, cultural background, and personal preferences.

However, in a broader context, there are certain medical conditions that can affect handwriting, such as neurological disorders (like stroke, Parkinson's disease, or cerebral palsy) or orthopedic issues (like arthritis or fractures). In these cases, healthcare professionals might assess a person's handwriting as part of the diagnostic process or to monitor the progression or treatment response of a condition. But again, handwriting itself is not a medical term with a specific definition.

I'm sorry for any confusion, but "linguistics" is not a term that has a medical definition. Lingustics is the scientific study of language and its structure. It involves analysing language form, language meaning, and language in context.

If you have any questions related to healthcare or medicine, I'd be happy to try to help answer them!

Neuronal migration disorders (NMDs) are a group of genetic conditions that affect the development and migration of neurons (nerve cells) in the brain during embryonic development. These disorders result from abnormalities in the genetic code that control the movement and organization of neurons as they migrate to their proper positions in the brain.

NMDs can cause a wide range of neurological symptoms, depending on which areas of the brain are affected and the severity of the disorder. Symptoms may include intellectual disability, developmental delay, seizures, motor abnormalities, vision or hearing problems, and behavioral issues. Some NMDs may also be associated with structural brain abnormalities that can be seen on imaging studies.

Examples of neuronal migration disorders include lissencephaly, pachygyria, heterotopias, and agyria. These conditions are typically diagnosed through a combination of clinical evaluation, genetic testing, and neuroimaging studies. Treatment for NMDs is generally supportive and may involve medications, therapies, and surgical interventions to manage symptoms and improve quality of life.

In the context of medicine, particularly in neurolinguistics and speech-language pathology, language is defined as a complex system of communication that involves the use of symbols (such as words, signs, or gestures) to express and exchange information. It includes various components such as phonology (sound systems), morphology (word structures), syntax (sentence structure), semantics (meaning), and pragmatics (social rules of use). Language allows individuals to convey their thoughts, feelings, and intentions, and to understand the communication of others. Disorders of language can result from damage to specific areas of the brain, leading to impairments in comprehension, production, or both.

Intelligence tests are standardized procedures used to assess various aspects of an individual's cognitive abilities, such as their problem-solving skills, logical reasoning, verbal comprehension, and spatial relations. These tests provide a quantitative measurement of intelligence, often reported as an Intelligence Quotient (IQ) score. It is important to note that intelligence is a multifaceted concept, and intelligence tests measure only certain aspects of it. They should not be considered the sole determinant of an individual's overall intellectual capabilities or potential.

I'm sorry for any confusion, but "vocabulary" is a term related to language and communication, rather than medicine or healthcare. It refers to the words and phrases that a person knows and uses in their communication. If you have any questions related to medical terminology or health-related topics, I would be happy to help with those!

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.

Auditory perception refers to the process by which the brain interprets and makes sense of the sounds we hear. It involves the recognition and interpretation of different frequencies, intensities, and patterns of sound waves that reach our ears through the process of hearing. This allows us to identify and distinguish various sounds such as speech, music, and environmental noises.

The auditory system includes the outer ear, middle ear, inner ear, and the auditory nerve, which transmits electrical signals to the brain's auditory cortex for processing and interpretation. Auditory perception is a complex process that involves multiple areas of the brain working together to identify and make sense of sounds in our environment.

Disorders or impairments in auditory perception can result in difficulties with hearing, understanding speech, and identifying environmental sounds, which can significantly impact communication, learning, and daily functioning.
