We reviewed 127 seizures in 19 consecutive patients with temporal lobe epilepsy (TLE) documented by EEG/closed-circuit TV (EEG-CCTV) monitoring. Ten patients had seizure onset in the right temporal lobe (RTL, 54 seizures), and 9 had seizure onset in the left temporal lobe (LTL, 73 seizures). We compared the clinical characteristics in the two groups and analyzed the seizures for frequency of auras, seizures secondarily generalized, automatisms, tonic head deviation, focal posturing and jerking, ictal speech, and postical manifestations. Automatisms overall were more common in the RTL group, but individual categories (extremity, head and trunk, oroalimentary) were comparable among the two groups. Contralateral focal jerking and tonic head deviation were more common in LTL lobe seizures, as were secondarily generalized seizures. In addition to focal motor symptoms, three features were most statistically significant in distinguishing the two groups: Postictal aphasia occurred exclusively in the LTL group, whereas well-formed ictal speech and rapid return to baseline postictally were noted only in RTL seizures.
