title: Cognitive functions of epileptic patients on monotherapy with phenobarbitone and healthy controls.
abstract: Quantitative measurements have indicated that heredity, cerebral damage, psycho-social aspects, ictal and inter-ictal phenomena and antiepileptic drugs may interfere in the cognitive dysfunction of epileptic patients. In the present study objective methods included immediate and late recall and recognition of pictures, Stroop test and auditory selection. Twenty patients with symptomatic localized epilepsy aged 17-52 years (27 +/- 10, mean +/- sd) were compared to age and socially matched healthy controls. Patients were on therapeutic serum concentrations (25 +/- 12 mu/ml) of phenobarbitone and had active epilepsy with 1.94 generalized tonic-clonic, 0.85 simple partial and 6.28 complex partial seizures monthly (means). Patients performed worse than controls in all 6 tests (p less than 0.05 to p less than 0.001), indicating a generalized cognitive deficit related to seizures and/or barbiturate therapy. We suggest further studies should be carried out in populations with uniform monotherapeutic regimens and epileptic syndromes in order to isolate factors related to the cognitive dysfunction of epileptic patients.
