Western Aphasia Battery

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). 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. The Western Aphasia Battery was introduced in 1980.

Another such test is the Boston Diagnostic Aphasia Examination.

WAB targets English-speakers between the ages of 18 and 89. It tests both linguistic and non linguistic skills. The linguistic skills assessed include, speech, fluency, auditory comprehension, reading and writing. Non-linguistic skills tested include drawing, calculation, block design, and apraxia.
