AbstractThis retrospective study evaluates the impact of postoperative antiepileptic drug (AED) withdrawal on psychomotor speed in seizure-free children, operated for medically refractory epilepsy. Post-surgical medication policy and neuropsychological assessments (performed shortly before and 6, 12 and 24 months after surgery), were evaluated in 57 children (32 female, median age at surgery 13 years). Patients were divided into a withdrawal (n=29) and a no-withdrawal group (n=28). Scores of four psychomotor tests performed at 12 and 24 months after surgery were compared with those of postoperative baseline measurements, performed 6 months after surgery. At 24 months, the withdrawal group had improved significantly more than the no-withdrawal group on three of four tests; reaction time to light (p=0.031), reaction time to sound (p=0.045) and tapping (p=0.003). At 12 months, a non-significant tendency in the same direction was found for both reaction time tests. Drug withdrawal after surgery improves psychomotor speed and may unleash the potential for cognitive improvement. Copyright © 2013 Elsevier B.V. All rights reserved.
