Studied STN stimulation in PET study. All had bilateral STN implantation. 12 patients showed worse apathy 3 months after STN stimulation. Motor function was used. The AES was used. PET showed positive correlation with right Brodmann's areas 10 (r frontal middle gyrus) and area 46 (R IFG) and negative correlation with right posterior cingulum (are 31) and left media frontal lobe ( area 9).

Postop neuropsych differed on WCST perseverative errors and Stroop.
