Aphasia is a language disorder, affecting the ability to comprehend and/or produce language. Importantly, aphasia is NOT an intellectual impairment. Only the ability to communicate is impaired.
Aphasia affects about one million Americans or 1 in 250 people, with more than 100,000 Americans acquiring the disorder each year (Source – NIH: NINDS). Most people with aphasia recover some language and communication ability, however, many do not recover completely. Recent research findings show that language (and brain function) improves with treatment, not only in the early stages following stroke, but for many years following the onset of aphasia.
