Psychology question, ! ? an elderly person suffered from a stroke that damaged part of his brain. he can speak easily, but his sentences make no sense. explain which area of his brain was most likely damaged.

Alright, from what you're telling me. (And trust me, I love neuroscience).

This patient most likely has a lesion/damage to his Brocha's or Wernicke's area. A neurological examination will have to be conducted in order to determine which one, test his language comprehension in order to rule out Wernicke's. If you're looking for a more general diagnosis, I'd roughly call it the Temporal lobe.
