Dr Rijnen and colleagues identified preoperative determinants of 12-month postoperative cognitive performance in 82 adults who underwent meningioma surgery. Preoperative determinants were assessed with a computerized neuropsychological battery on the day before surgery and during follow-up.¹ It raises two methodological questions about (1) how the use of medication has been taken into account and (2) the validity of the measurements on the day before surgery.
