Ten patients with refractory temporal lobe epilepsy performed a word-position association learning task every 24 hours during video EEG monitoring. On 55 occasions recall performance was tested 30 minutes and 24 hours after the initial learning phase. Patients with left- but not right-sided temporal lobe epilepsy exhibited impaired retention of word position if a seizure had occurred during the preceding 24-hour interval. Seizures may impair the consolidation of memory in patients with left-sided temporal lobe epilepsy beyond the chronic memory deficits caused by the underlying pathology.
