Aphasia

Aphasia is an inability to understand or formulate language due to damage to specific brain regions . The main causes are a stroke or head trauma, but aphasia may also result from brain tumors, brain infections, or neurodegenerative diseases such as dementia. The latter, however, are far less common and therefore not as often mentioned when discussing aphasia. To be diagnosed with aphasia, a person's speech or language must be significantly impaired in one (or more) of the four communication aspects following acquired brain injury, or significantly decreased over a short period of time (progressive aphasia) Auditive comprehension, verbal expression, reading and writing, and functional communication are the four aspects of communication. Also it can affect expressive language and receptive language. Aphasia also has an influence on visual language including sign language.
