<unk>  is a disorder that results from damage to portions of the brain that are responsible for language. For most people, these are areas on the left side (hemisphere) of the brain.<unk>  usually occurs suddenly, often as the result of a stroke or head injury, but it may also develop slowly, as in the case of a brain tumor, an infection, or dementia. The disorder impairs the expression and understanding of language as well as reading and writing.<unk>  may co-occur with speech disorders such as dysarthria or apraxia of speech, which also result from brain damage.
