Wernicke’s Aphasia

Wernicke’s Aphasia

Background

Aphasia can be defined as a disorder that is caused by damage to parts of the brain that are responsible for language (“Aphasia” n.p.). Wernicke’s aphasia is a type of fluent aphasia (with the other type being nonfluent). It is named after Carl Wernicke who described the disorder as “an amnesiac disorder characterized by fluent but disordered speech, with a similar disorder in writing, and impaired understanding of oral speech and reading” (“Wernicke’s” n.p.). Wernicke’s aphasia can also be known as sensory aphasia, fluent aphasia, or receptive aphasia. It is a type of aphasia that is caused by damage to Wernicke’s area in the brain, in the posterior part of the temporal lobe of the left hemisphere. This area of the brain contains motor neurons responsible for the understanding of spoken language and is believed to be the receptive language center (“Rogers” n.p.). Wernicke’s aphasia can be most efficiently defined as a fluent language disorder commonly caused by strokes and characterized by difficulty comprehending spoken language and producing meaningful speech and writing which is both assessable by an SLP and treatable by a variety of methods.

Etiology

The onset of aphasia is extremely quick. It usually is found in people who have no former history of speech or language problems. The lesion leaves the affected area of the brain unable to function as it did only moments before (Owens 203).Wernicke’s aphasia is caused by damage to Wernicke’s area which can result from head injury, brain tumors, infections, dementia, or the most common cause, stroke. A posterior stroke that is isolated to Wernicke’s area does not result in total weakness of the arm and leg on the opposite ...
