The Lennox-Gastaut syndrome has been a source of interest for many workers both from a clinical and electroencephalographic view point. Treatment has always posed problems. Without suggesting an ideal medication for this syndrome, the authors have obtained good results with barbexaclone. Taking into consideration the convulsive manifestations, psychic changes and electroencephalographic details as parameters the therapeutic efficacy of this drug was studied in seven cases.

In a group of rhesus monkeys (Macaca mulatta) inoculated intracerebrally and intravenously with a strain (Enage strain rhesus L6 56) of kuru already passaged in rhesus monkeys, 1 monkey presented the typical EEG pattern of epileptogenic encephalopathy reminiscent of the Lennox-Gastaut syndrome. This observation provides no direct evidence for the viral origin of epilepsies of this type. It does, however, show that it is possible to induce an epileptogenic encephalopathy by an unconventional infectious agent.

Myoclonus is a phenomenon which cuts through a considerable number of neurological conditions. It occurs in a variety of epileptic conditions (Primary generalized epilepsy, hypsarrhythmia, Lennox-Gastaut syndrome, also known as "petit mal variant"), in inborn errors of metabolism (Tay-Sachs disease, forms of ceroid lipofuscinosis), in neurobiochemically still poorly understood forms of degenerative processes such as Essential hereditary myoclonus epilepsy (Lafora-Unverricht-Lundborg), in benign heredo-degenerative disorders (Hartung's syndrome), in CNS infections (SSPE, Jakob-Creutzfeldt disease), in metabolic encephalopathies (renal failure, hypoglycemia), in CNS poisoning, in acute cerebral anoxia and in post-anoxic states. The EEG plays a crucial role in the differential diagnosis of these conditions by the demonstration of a) presence or absence of typical inter-ictal abnormalities, and b) various correlates of the myoclonic ictal event.

A 14-year-old boy had suffered from intermittent acute hepatic porphyria, myoclonic convulsions and mental retardation (Lennox-Gastaut syndrome). The porphyria was treated by stopping the administration of phenobarbitone and phenytoin. Sodium valproate at a dose of 70 mg/kg per day lessened the severity and frequency of convulsive crises.

During the evolution of a treated A.L.L. (without C.N.S. radiotherapy) in a young girl, the development of leukemic meningitis and a Lennox-Gastaut syndrome were observed. Abnormal intra-cerebral lesions are observed by computerized transverse axial tomography. These lesions are presumably secondary to lymphoblastic infiltration. There were no lymphoblasts in the C.S.F. This new method of exploration of the central nervous system which is strictly atraumatic, is considered as a valuable adjunct to the lumbar puncture in the control of the neurological complications of acute leukemia.

The electroencephalographic findings observed in twenty-nine patients with Lennox-Gastaut syndrome were related with prognosis of the epileptic manifestations. The presence of slow spike-wave complexes with preponderance of spike over the slow wave and the presence of fixed complexes in spite of the medical treatment, are related with poor prognosis for the epileptic manifestations.

Sulthiame has been used by most investigators in psychomotor seizures, other focal seizures and grand-mal, usually in conjuction with other anticonvulsants. Reports on its use in myoclonic epilepsy and as a sole anti-convulsant are few and inconclusive. The present report presents the results of a study carried out on the use of sulthiame in 54 cases of myoclonic epilepsies originating in infancy, childhood and adolescence. The different types of myoclonic epilepsy are defined. An illustrative case report is included. Results indicated that sulthiame is the drug of choice, often as the sole anti-convulsive agent, in cases of "juvenile myoclonic epilepsy". In the myoclonic encephalopathies of childhood (the so-called "minor motor epilepsy" or Lennox-Gastaut syndrome), which are notoriously refractory to therapy, sulthiame appears to be an efficacious adjunct to currently-used agents, including benzodiazepines, succinimides, dipropyl acetate, steriods and a ketogenic diet.

Computerized axial tomography (CAT) in 38 patients with Lennox-Gastaut syndrome showed normal findings in 20 patients and abnormalities in 18; diffuse cerebral atrophy (8) was the most common abnormality. These findings are not basically different from those recently reported by Gastaut and Gastaut (1976). Emphasis is laid upon age and possible increase of diffuse abnormalities with advancing age. The observation of 2 cases with cerebellar atrophy is also discussed.

Clinical and electroensephalographic aspects of twenty seven (27) patients with Lennox-Gastaut syndrome were studied (20 without previous West syndrome, group A, and 7 with this antecedent, group B). The epileptic seizures were characterized through descriptions made by relatives who were in close contact with the patients, and also by direct observation by the author in the clinic. The direct observation was possible due to high frequency of the seizures. Denominations were given to the manifestations not previously mentioned in the literature, according to the quality and eventual sequence of observable phenomena, in agreement with the terminology used by the Clinical and EEG Classification of Epileptic Seizures. The incidence, prognostic, clinical and evolutive aspects of elementary forms of epileptic seizures were discussed. Great variability of the convulsive seizures was verified, permitting their division into simple, complex and mixed forms.

Clinical and electroencephalographic aspects of partial and non convulsive forms of epileptic seizures of twenty seven (27) patients with Lennox-Gastaut syndrome were studied (20 without previous West syndrome, Group A, and 7 with this antecedent, group B). The epileptic seizures were characterized through descriptions made by relatives who were in close contact with the patients, and also by direct observation by the author in the clinic. The direct observation was possible due to high frequency rates of the seizures. Denominations were given to the manifestations not previously mentioned in the literature, according to the quality and eventual sequence of observable phenomena, in agreement with the terminology used by the Clinical and EEG Classification of Epileptic Seizures. The incidence and clinical aspects of elementary partial and non-convulsive forms of epileptic seizures were discussed. Great variability of the non-convulsive seizures was verified permiting their division into simple, complex and mixed forms, similarly to the absences. Unilateral forms of atonic seizures were identified.
