Overview
Aphasia from the Greek root word \"aphatos\", meaning speechless, is an acquired language disorder in which there is an impairment of any language modality. This may include difficulty in producing or comprehending spoken or written language. Traditionally, aphasia suggests the total impairment of language ability, and dysphasia a degree of impairment less than total. However, the term dysphasia is commonly confused with dysphagia, a swallowing disorder, and thus aphasia has come to mean both partial and total language impairment in common use.
