Non-verbal Learning Disorder
Nonverbal learning disability (NVLD) is a neurodevelopmental disorder characterized by core deficits in visual-spatial processing in the presence of intact verbal ability. Additional diagnostic criteria include Average to Superior verbal intelligence and deficits in visuoconstruction abilities, fine-motor coordination, mathematical reasoning, visuospatial memory and social skills. In clinical settings, some diagnoses of attention deficit hyperactivity disorder would be more appropriately classified as NVLD. Signs and symptoms Considered to be neurologically based, nonverbal learning disorder is characterized by: * impairments in visuospatial processing * discrepancy between Average to Superior verbal abilities and impaired nonverbal abilities such as: ** visuoconstruction ** fine motor coordination ** mathematical reasoning ** visuospatial memory ** socioemotional skills People with NVLD may have trouble understanding charts, reading maps, assembling jigsaw puzzles, and usin ...

Neurodevelopmental Disorder
Neurodevelopmental disorders are a group of disorders that affect the development of the nervous system, leading to abnormal brain function which may affect emotion, learning ability, self-control, and memory. The effects of neurodevelopmental disorders tend to last for a person's lifetime. Types Neurodevelopmental disorders are impairments of the growth and development of the brain and/or central nervous system. A narrower use of the term refers to a disorder of brain function that affects emotion, learning ability, self-control and memory which unfolds as an individual develops and grows. According to the DSM-5, the neurodevelopmental disorders include the following: # Attention deficit hyperactivity disorder (ADHD) # DLD - Developmental language disorder (formerly known as SLI- Specific Language Impairment) # Communication, speech, or language disorders, expressive language disorder, fluency disorder, social (pragmatic) communication disorder, and speech sound disorder. # ...

Gerstmann Syndrome
Gerstmann syndrome is a neuropsychological disorder that is characterized by a constellation of symptoms that suggests the presence of a lesion usually near the junction of the temporal and parietal lobes at or near the angular gyrus. Gerstmann syndrome is typically associated with damage to the inferior parietal lobule of the dominant hemisphere. It is classically considered a left-hemisphere disorder, although right-hemisphere damage has also been associated with components of the syndrome. It is named after Jewish Austrian-born American neurologist Josef Gerstmann. Symptoms Gerstmann syndrome is characterized by four primary symptoms, collectively referred to as a tetrad: # Dysgraphia/agraphia: deficiency in the ability to write # Dyscalculia/acalculia: difficulty in learning or comprehending mathematics # Finger agnosia: inability to distinguish the fingers on the hand # Left-right disorientation Causes This disorder is often associated with brain lesions in the domina ...

Right Hemisphere Brain Damage
Right hemisphere brain damage (RHD) is the result of injury to the right cerebral hemisphere.American Speech-Language-Hearing Association. (2015). ''Right hemisphere brain damage''. Retrieved from http://www.asha.org/public/speech/disorders/RightBrainDamage/ The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. Deficits caused by right hemisphere brain damage vary depending on the location of the damage.Brookshire, R. H. (2007). Right hemisphere syndrome. In K. Falk (Ed.), ''Introduction to Neurogenic Communication Disorders'' (7th ed., pp. 391-443). St. Louis, MO: Mosby Elsevier. Signs and symptoms Visual processing Individuals with right hemisphere damage exhibit deficits in visual processing. It appears as though they are only able to recognize the parts of a picture, symbol, etc. rather than seeing the image as a whole. This was shown during an experiment when patients with right hemisphere dama ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Social Communication Disorder
Social (pragmatic) communication disorder (SPCD) - previously called semantic-pragmatic disorder (SPD) or pragmatic language impairment (PLI) - is a disorder in understanding pragmatic aspects of language. People with SPCD have special challenges with the semantic aspect of language (the meaning of what is being said) and the pragmatics of language (using language appropriately in social situations). Individuals have difficulties with verbal and nonverbal social communication. Relates to Pragmatic Language Impairment and Autism Spectrum Disorder. It has only been since 2013 that SPCD has become its own category in the DSM-5. In creating this new category it allowed individuals to be considered with a form of communication disorder ''distinct'' from PLI and ASD. As well, SPCD lacks behaviors associated with restrictions and repetition which are seen in ASD.
