Aphasia Syndromes

Aphasia is an acquired disorder of language. It can manifest in various ways, including difficulty speaking or difficulty understanding speech or language. Stroke is the most common cause of aphasia with up to 40% of stroke patients experiencing some sort of aphasia. Depending on the nature of the injury (e.g., stroke, tumor, trauma), aphaisa can be temporary or permanent. Even in cases of severe stroke, some types and aspects of aphasia are treatable, with language improving over time. While language does not usually return to pre-morbid functional levels, many people with aphasia benefit greatly from speech therapy.

The following videos demonstrate two different types of aphasia – Broca’s aphasia (or non-fluent) and Wernicke’s aphasia (or fluent). Notice the differences between the aphasias.
