“…In recent years, the use of telemetry with automatic sampling techniques (Ives et al, 1974), devised by Mr. John Ives, our neuroelectronic engineer and his team, has greatly increased the capability of recording large numbers of interictal epileptiform spikes over long periods and during various types of daily activity and during different phases of sleep without adding an undue burden and cost to the EEG laboratory. An automatic spike detection unit (Gotman and Gloor, 1976;Gotman et al, 1979) developed by Dr. Jean Gotman permits a quantitative analysis of spike localization and lateralization to a degree not possible to date by the traditional eyeball analysis.…”

“…Spontaneous attacks have occasionally been recorded since the earliest days of the EEG era at the MNI, but it is only since the introduction of relatively routine telernetry that the EEG recording of clinical seizures has become a major aspect of the study of patients with complicated seizure problems (Ives et al, 1974(Ives et al, , 1976. When the EEG record of the seizure onset is technically satisfactory, it provides the most reliable primary localizational and lateralizing information.…”

The underlying seizure tendency of complex partial seizures often involves the temporal region of the brain, but the frontal lobe can also produce similar complex partial seizures. By the end of 1980, 1,210 patients with medically refractory temporal lobe epilepsy had been operated on at the Montreal Neurological Institute. Nontumoral epileptogenic lesions were present in 1,034 patients, 169 had tumors, and 7 had major vascular malformations. Thirty-seven percent of the 894 evaluable patients with nontumoral epileptogenic lesions have become and remained seizure-free. Two hundred thirty-six (26%) patients had a marked reduction of seizure tendency. Within the seizure-free group, 63% had a complete or nearly complete reduction of their medically refractory tendency following temporal lobectomy. Of the patients with temporal lobe epilepsy due to tumoral lesions, 46% of the evaluable patients have become and remained seizure-free, and 76% have had a complete or nearly complete reduction of seizure tendency.

The past decade has seen advances in the management of patients with epilepsy. The development of practical long-term electroencephalographic techniques, with or without simultaneous video recording, has increased the accuracy of diagnosis of seizure types. The technique also provides clinicians and investigators with a method for establishing the clinical efficacy of antiepileptic drugs and determining their therapeutic serum concentrations. Computerized tomography has enhanced the identification of structural brain lesions. Most of the reported CT abnormalities consist of diffuse and focal atrophies, mild ventricular dilatations, and porencephalies. CT has detected tumors in 8 to 10% of the patients regardless of age or type of seizure involved. New concepts of antiepileptic drug therapy have developed from the recognition of pharmacological properties peculiar to each agent. Determination of serum antiepileptic drug levels has to be utilized to reduce the problem of pharmacokinetic variability from one patient to another and in the same patient at different times, so that dosage can be individualized to achieve maximum therapeutic effects with least toxicity. Review of the literature on pregnancy in epileptic women shows that a third to half experienced more seizures during gestation. Reduced serum levels of most antiepileptic drugs have recently been observed during gestation. Infants of epileptic women taking antiepileptic drugs have a two to three times greater risk for congenital anomalies than infants of nonepileptic women. However, with the exception of oxazolidinediones, evidence to date has not proved the teratogenicity of antiepileptic drugs. The role of genetic factors and the effect of seizures during pregnancy have not been determined. Modest progress has been made in epilepsy rehabilitation, but serious problems still remain. The unemployment rate of persons with epilepsy is twice the national average. Half of those who are successfully employed did not disclose their disorder at the time of employment. Several prognostic indicators have been reported, but the validity of many of these indicators is questionable. For example, does shorter life expectancy apply to all subgroups, or does it vary according to seizure type and cause? The life expectancy, treatment response, and probability of remission in epileptic persons must be reevaluated after consistent applications of current methods of epilepsy management.
