Aphasia is a condition that affects the brain and leads to problems using language correctly.Aphasia is often classified as 'expressive' or 'receptive' aphasia, depending on whether there are difficulties with understanding or expressing language, or both.The term aphasia implies that one or more communication modalities have been damaged and are therefore functioning incorrectly.
Aphasia is most often caused by stroke, but any disease or damage to the parts of the brain that control language can cause aphasia. Some of these can include brain tumors, traumatic brain injury, and progressive neurological disordersOnce the cause has been addressed, the main treatment for aphasia is speech and language therapy. The person with aphasia relearns and practices language skills and learns to use other ways to communicate.
