3. Aphasia is an impairment (but not loss) of speech and of comprehension of speech. Aphasia usually results from lesions to the language-relevant areas of the brain, such as Broca's area, Wernicke's area, and the neural pathways between them. Depending on the area and degree of the damage, someone suffering from aphasia may be able to speak but not write, or vice versa, or display any of a wide variety of other deficiencies in language conception and production, such as being able to sing but not speak. Aphasia may co-occur with speech disorders such as dysarthria or apraxia of speech, which also result from brain damage.

Major causes are stroke, trauma, poliomyelitis, amyotrophic lateral sclerosis (ALS), botulism, spina bifida, multiple sclerosis, and Guillain-Barré syndrome.
