Fig. 1.

Clock drawing test to command and copy conditions completed preoperatively (7 days before surgery) and postoperatively (42 days postoperatively) in a 76-year-old individual. Preoperative drawings show frontal compromise on the command condition (A, incorrect hand placement, gap in number spacing) and subtle signs in the copy condition (B, hands touching numbers, hands equal in length, gap in number spacing). Postoperative drawings show frontal impairment in command condition (C, increased perseverations, intrusions, incorrect number placement, missing hands) with subtle signs in the copy condition (D, hands of equal length, number gaps, self-correction of hand and number)
