Aphasia is a communication disorder and defined as acquired (= not inherited, acquired afterwards) loss of language function due to brain injury in an area related to comprehension and speech production. It refers to any partial or total loss of language skills in adults and children and general inability to speak. Aphasia can be permanent or temporary and in most cases manifests itself suddenly. Aphasia is usually the result of a stroke. Other etiologies include accidents, tumors, infections, toxicity.
Speech and language therapy is the major treatment for aphasia once the reason has been identified. The person with aphasia relearns and practices language abilities, as well as learning to communicate in other ways. Family members are frequently involved in the process, assisting the person in communicating.
