Aphasia

Aphasia is the inability to use language appropriately and may include problems speaking language, hearing language, and reading language. Some with aphasia are able to read properly, but can't speak the language, speak the language but not be able to read it, or read letters but not numbers. Aphasia usually results from damage to parts of the brain such as Broca's (speaking problems) area or Wernicke's area (understanding language problems).
