Ataxia refers to a lack of coordinated muscle movements that include gait abnormality and is the cerebellar sign that typifies all spinocerebellar ataxia (SCA) types, though individuals with SCA1 also develop pyramidal and bulbar signs as the disease progresses. The average age of onset is between 30 and 40 years of age, though exceptions exist.
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 .

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 ...
Western Aphasia Battery (WAB) is an instrument for assessing the language function of adults with suspected aphasia as a result of a stroke, head injury, or dementia. The updated version is the Western Aphasia Battery-Revised (WAB-R). [1] The battery helps discern the presence, degree, and type of aphasia.
