What does the Western Aphasia Battery test for?
Western Aphasia Battery (WAB) is an instrument for assessing the language function of adults with suspected neurological disorders as a result of a stroke, head injury, or dementia. There is an updated version, the Western Aphasia Battery-Revised (WAB-R). It helps discern the presence, degree, and type of aphasia.

How do you calculate aphasia Quotient in WAB?
Aphasia types were categorized using Kertesz’s classification (9), and aphasia severities were quantified using Aphasia Quotients (AQ; range 0-100), which were calculated using the formula proposed by Kertesz (10) (fluency score+comprehension score/20+repetition score /10+naming score/10)×2.
Which type of aphasia is the most severe?
Global aphasia is the most severe type of aphasia. It is caused by injuries to multiple parts of the brain that are responsible for processing language. Patients with global aphasia can only produce a few recognizable words. They can understand very little or no spoken language.
