One such Bayesian classifier was shown to accurately predict 78% of SCA cases out of a cohort with known types of SCA. The sensitivity and specificity for SCA1 within this model was 76.9% and 98.2% respectively. Regional variance in prevalence, symptoms and clinical assessment might still limit the use of this system on large scales, though the ...

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 .
[10] [11] [12] In the classical Mesulam criteria for primary progressive aphasia, there are two variants: a non-fluent type PNFA and a fluent type SD. [13] [14] A third variant of primary progressive aphasia, LPA was then added, [15] and is an atypical form of Alzheimer's disease. For PNFA, the core criteria for diagnosis include agrammatism ...
The Boston Diagnostic Aphasia Examination is a neuropsychological battery used to evaluate adults suspected of having aphasia, and is currently in its third edition. [1] It was created by Harold Goodglass and Edith Kaplan. The exam evaluates language skills based on perceptual modalities (auditory, visual, and gestural), processing functions ...
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 simplest example is sentences in the passive voice, such as "The boy was chased by the girl." Expressive aphasics may have quite a hard time realizing that the girl is doing the chasing, but they do much better with "The mouse was chased by the cat," where world knowledge constraints contribute to the correct interpretation.
The updated version is the Western Aphasia Battery-Revised (WAB-R). [1] The battery helps discern the presence, degree, and type of aphasia. It can provide a baseline for monitoring changes during therapy. It is useful for determining what to treat. It can provide indications of the location of the lesion that caused the aphasia. [2]
