title: Adverse behavioral response to clonazepam as a function of Verbal IQ-Performance IQ discrepancy.
abstract: Eight of 38 consecutive patients who received clonazepam had significant behavioral side effects. In these 8 patients, the mean absolute IQ discordance between Verbal IQ (VIQ) and Performance IQ (PIQ) was 17.5 points. Thirty of 38 patients had no adverse behavioral side effects while receiving clonazepam. In these 30 patients, the mean absolute VIQ-PIQ discrepancy was 6.5 points. Full neuropsychological testing had been performed on all patients. The only test variable showing a statistically significant difference was the absolute discrepancy between VIQ and PIQ (P less than 0.0001).
