Síndrome de Lennox: atualização

1977

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.

Foram descritos os estados de mal epilépticos, convulsivos e não convulsivos, observados em 14 de 27 pacientes com síndrome de Lennox-Gastaut, regularmente seguidos em regime de ambulatório. Às manifestações não citadas na literatura foram atribuídas denominações baseadas na qualidade e eventual seqüência dos fenômenos observados, obedecidas as regras de terminologia constante na Classificação Internacional das Epilepsias. Foram discutidos a incidência, significado prognóstico e aspectos clínicos do estado de mal. Verificadas a elevada incidência e a freqüente atipia dos estados de mal epiléptico foi proposta uma classificação destas complicações.

Comparação entre as manifestações epilepticas ocorridas na Sindrome de Lennox-Gastaut, com e sem Sindrome de West pregressa

Cclinical and electroencephalographic 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 rates of the seizures. Different clinical patterns were observed in patients who had and who had not previous history of West syndrome. The analysis of these differences permitted the identification of two groups of patients, although both of them had sharp and slow waves in the EEG. The clinical picture of each group was interpreted as the result of the stage of cerebral maturation at the time the diffuse epileptic encephalopathy occurred.
