What is Aphasia?

Aphasia is a language impairment caused by neurologic damage, usually to the left hemisphere of the brain. It can effect how a person comprehends language (receptive) or uses language (expression). It can also cause a "global" impairment of language (effecting both reception and expression). Aphasia is commonly diagnosed in the early stages of recovery after a stroke or a head injury. People typically receive speech therapy to improve their language skills. Prognosis for improvement varies based on type and location of brain injury and severity of lesion.
