After a mild stroke, Patient showed some signs of aphasia. what pattern of symtoms would lead you to beleive the damage occured primary in the -->
(a) broca's area, (b) Wernicke's area, (c) the angular gyrus?
explain the symtoms and area most affected, least affected.
answer in a psychological perspective. :D
Aphasia means that the patient would have difficulty with language, be it understanding language or with reading and writing. If you remember, Broca's area is in the frontal section of the brain. If this area was affected (also called Broca's aphasia) the patient tend to speak in short phrases that make sense, but tend to omit small words (is, and, ect.) So, if they are trying to ask for a glass of water, they might say "want water). Patients with Broca's aphasia usually understand the speech of others fairly well and can have motor weakness or paralysis on the right side.
Wernicke's area is located in the temporal lobes. Patients with Wernicke's aphasia tend to speak in long sentences that have no meaning, including unnecessary words and made-up words. They usually have trouble understanding language, but no motor issues.
The angular gyrus is located in the parietal lobe of the brain. This area is responsible for processing visual and auditory input, and comprehension of language. Therefore, a patient with damage in the angular gyrus would have trouble with reading and writing and have trouble finding specific names or words.
Hope this helps!
