SUMMARY

The objective of this study was to establish the etiology of epilepsy in 210 chronic epileptics (110 female, 100 male), aged 14-82 years (34.2±13.3). Patients less than 10 years-old and alcoholism were excluded. All underwent neurological examination, routine blood tests, EEG and CT-scan. Twenty patients (10.5%) were submitted to spinal tap for CSF examination. Neurological examination was abnormal in 26 (12.4%), the EEG in 68 (45.5%), and CT-scan in 93 (44.3%). According to the International Classification of Epileptic Seizures (1981), 101 (48.1%) have generalized seizures, 66 (31.4%) partial seizures secondarily generalized, 25 (11.8%) simple partial and complex partial seizures, and 14 (6.6%) generalized and partial seizures. Four patients (2.0%) could not be classified. In 125 (59.5%) patients the etiology was unknown. Neurocysticercosis accounted for 57 (27.1%) of cases, followed by cerebrovascular disease 8 (3.8%), perinatal damage 5 (2.4%), familial epilepsy 4 (1.9%), head injury 4 (1.9%), infective 1 (0.5%), and miscelanea 6 (2.8%).


RESUMO

Foram investigados prospectivamente 210 pacientes epilépticos crônicos (110 mulheres, 100 homens), idade variando de 14 a 82 anos (34,2±13,3) no sentido de estabelecer a etiologia de suas crises epilépticas. Pacientes com menos de 10 anos e com alcoolismo foram excluídos. Todos foram submetidos a anamnese, exames físico e, neurológico, exames laboratoriais de rotina, EEG e TC. Vinte pacientes (10,5%) foram submetidos a punção lombar para exame do LCR. O exame neurológico foi anormal em 26 (12,4%), o EEG em 68 (46.5%) e a TC em 93 (44,3%). De acordo com a Classificação Internacional de Epilepsia (1981), 101 (48,1%) apresentavam crises generalizadas primarias, 66 (31,4%) crises parciais secundariamente generalizadas, 25 (11,8%) crises parciais simples ou complexas e 14 (6,6%) crises parciais e crises generalizadas; 4 (2,0%) pacientes não puderam ser classificados. Em 125 pacientes (59,5%) a etiologia da epilepsia não foi estabelecida. Neurocisticercose foi a causa identificável mais comum, 57 casos (27,1%), seguida pelos acidentes cerebrovasculares 8 (3,8%), sofrimento perinatal 5 (2,4%), epilepsia familial 4 (1.9%), trauma craniano 4 (1,9%), infecção 1 (0.5%) e miscelânea 6 (2,8%).
