title: Arachnoid cysts cause cognitive deficits that improve after surgery.
abstract: The authors investigated cognition in patients with arachnoid cysts by assessing 55 patients and 32 control subjects on four different cognitive tests preoperatively and 3 months postoperatively. The patients improved their performance from preoperative to postoperative testing, whereas the control subjects did not show a similar improvement.
