The damage of aphasia

The damage of aphasia tends to be in two brain areas, the Broca's area in the posterior left prefrontal cortex, and Wernicke's area, the posterior left temporal cortex.

• In Brocha's aphasia, people have problems with fluency, mixing the order of the words, and ignoring grammar.
• In Wernicke's aphasia, the language becomes confused or even nonsense. It can also limit fluency and word formation.
• Global aphasia describes a severe loss of the ability to communicate or understand language.
