DIFFERENTIATING CLINICAL-FEATURES OF RIGHT AND LEFT TEMPORAL-LOBE SEIZURES

We reviewed 127 seizures in 19 consecutive patients with temporal lobe epilepsy (TLE) documented by EEG/closed-circuit TV (EEG-CCTV) monitor ing. Ten patients had seizure onset in the right temporal lobe (RTL, 5 4 seizures), and 9 had seizure onset in the left temporal lobe (LTL, 7 3 seizures). We compared the clinical characteristics in the two group s and analyzed the seizures for frequency of auras, seizures secondari ly generalized, automatisms, tonic head deviation, focal posturing and jerking, ictal speech, and postical manifestations. Automatisms overa ll were more common in the RTL group, but individual categories (extre mity, head and trunk, oroalimentary) were comparable among the two gro ups. Contralateral focal jerking and tonic head deviation were more co mmon in LTL lobe seizures, as were secondarily generalized seizures. I n addition to focal motor symptoms, three features were most statistic ally significant in distinguishing the two groups: Postictal aphasia o ccurred exclusively in the LTL group, whereas well-formed ictal speech and rapid return to baseline postictally were noted only in RTL seizu res.
