Genetic testing is available for many SCA types, including the relatively common types SCA1, 2, 3, 6, and 7; and the less common SCA8, 10, 12, 14, and 17. [39] However, genetic testing is high in cost and has a low diagnostic yield, with positive diagnoses being found in only 24% of tests ordered by a subspecialist and 10% overall. [40]
Spinocerebellar ataxia (SCA) is a progressive, degenerative, [1] genetic disease with multiple types, each of which could be considered a neurological condition in its own right. An estimated 150,000 people in the United States have a diagnosis of spinocerebellar ataxia at any given time. SCA is hereditary, progressive, degenerative, and often ...
The Boston Naming Test (BNT), introduced in 1983 by Edith Kaplan, Harold Goodglass and Sandra Weintraub, is a widely used neuropsychological assessment tool to measure confrontational word retrieval in individuals with aphasia or other language disturbance caused by stroke, Alzheimer's disease, or other dementing disorder.

The test contains a cognitive screening, a language battery and a disability questionnaire. The authors of the comprehensive aphasia test take account of current linguistic and psychological theory and other variable that impact aphasic performance. The CAT was published in 2005 and was the first new aphasia test in English for 20 years.
Lateral medullary syndrome is a neurological disorder causing a range of symptoms due to ischemia in the lateral part of the medulla oblongata in the brainstem.The ischemia is a result of a blockage most commonly in the vertebral artery or the posterior inferior cerebellar artery. [1]
The Boston Diagnostic Aphasia Examination provides a comprehensive exploration of a range of communicative abilities. Its results are used to classify patient's language profiles into one of the localization based classifications of aphasia: Broca's, Wernicke's, anomic, conduction, transcortical, transcortical motor, transcortical sensory, and global aphasia syndromes, although the test does ...
Canine cognitive dysfunction (CCD) is a disease prevalent in dogs that exhibit symptoms of dementia or Alzheimer's disease shown in humans. [1] CCD creates pathological changes in the brain that slow the mental functioning of dogs resulting in loss of memory, motor function, and learned behaviors from training early in life.
The Brixton test is a visuospatial sequencing task with rule changes. This test measures the ability to detect rules in sequences of stimuli. It usually takes between five and ten minutes to administer, and yields an easily understood scaled score of between 1 and 10. The Brixton Test is perceptually simple and does not require a verbal response.
