It is well-known that patients suffering from idiopathic partial epilepsies (IPE) may have abnormally large somatosensory evoked potentials (SEPs). Clinical records of 6 IPE-patients with enlarged SEPs (ESEPs) were compared with those of 14 IPE-patients with normal SEPs in order to evaluate differences in the following clinical tasks: familial antecedents for febrile convulsions and/or epilepsy, personal antecedents for perinatal damage, neonatal seizures and febrile convulsions, age of onset of epilepsy, frequency of seizures after antiepileptic treatment, neurologic and neuropsychologic examinations (including tests of parietal lobe functions: extinction of double tactile stimulus, two-point discrimination, fingertip). The only relevant difference was seizure frequency before antiepileptic treatment: during a follow-up period of 3-120 months, all patients with ESEPs and 5 out of 14 (36%) patients with normal SEPs had low (≤ 1/three months) or very low (≥ 1/year) frequency of seizures. We conclude that ESEPs is a favourable marker in patients suffering from idiopathic partial epilepsy.

Abstract
It is well-known that patients suffering from idiopathic partial epilepsies (IPE) may have abnormally large somatosensory evoked potentials (SEPs). Clinical records of 6 IPE-patients with enlarged SEPs (ESEPs) were compared with those of 14 IPE-patients with normal SEPs in order to evaluate differences in the following clinical tasks: familial antecedents for febrile convulsions and/or epilepsy, personal antecedents for perinatal damage, neonatal seizures and febrile convulsions, age of onset of epilepsy, frequency of seizures after antiepileptic treatment, neurologic and neuropsychologic examinations (including tests of parietal lobe functions: extinction of double tactile stimulus, two-point discrimination, fingertip). The only relevant difference was seizure frequency before antiepileptic treatment: during a follow-up period of 3-120 months, all patients with ESEPs and 5 out of 14 (36%) patients with normal SEPs had low (≤ 1/three months) or very low (≥ 1/year) frequency of seizures. We conclude that ESEPs is a favourable marker in patients suffering from idiopathic partial epilepsy.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
