RATIONALE: Neuropsychological changes may follow temporal lobectomy. Information on visuospatial and visuomotor changes following nondominant temporal lobectomy is limited.
METHODS: Twentythree consecutive patients undergoing right temporal lobectomy underwent neuropsychological testing prior to surgery ( 11 males,12 females,mean age at surgery 37.7 years). Postoperative testing was done in 19 patients six months after surgery.Surgery consisted of 4 to7 cm anteroposterior as well as amygdala/ anterior hippocampal resection.The following were tested: Wechsler Adult Intelligence Scale-Revised or Wechsler Abbreviated Scale of Intelligence,Visual Form Discrimination,Judgement of Line Orientation,Trailmaking Tests,Grooved Pegboard Test,Finger Tapping,and Handdynamometer.
RESULTS: No changes were seen postoperatively in perceptual -organisational and motor components of general intelligence tests and in other visuomotor tests. However,a significant improvement in handgrip strength was seen for nondominant hand postsurgery(t=-3.876,p[lt]0.006)
CONCLUSIONS: There is no evidence visuospatial/visuomotor deterioration following right temporal lobectomy.Findings suggest an improvement in left hand grip strenth during followup.
