What is aphasia?
Aphasia is a disorder that results from damage to portions of the brain which are responsible for language. For most people these are areas on the left side (hemisphere) of the brain. Aphasia usually occurs suddenly, often as a result of a stroke or head injury. The disorder impairs the expression and understanding of language as well as reading and writing, in fact it can affect all communication for some people.
What causes aphasia?
Aphasia is caused by damage to one or more of the language areas of the brain. Often, the cause of the brain injury is a stroke. A stroke occurs when blood is unable to reach a part of the brain. Brain cells die when they do not receive their normal supply of blood which carries oxygen and important nutrients. Other causes of brain injury are severe blows to the head, brain tumours, brain infections, and other conditions which affect the brain.
Who has aphasia?
Anyone can suffer with aphasia, including children.
According to the National Aphasia Association over 80,000 individuals acquire aphasia each year as a result of a stroke.
