Abstract(s)
Introdução: Uma crise epilética é a manifestação clínica ou psíquica de um processo anormal de hiperatividade e/ou hipersincronia elétrica neuronal cerebral, que pode acometer o cérebro de forma parcial (focal) ou generalizada. Pode também variar, do mais breve lapso de atenção, ou espasmo muscular, até severas e prolongadas convulsões. As crises epiléticas afetam cerca de 2 a 3% da população mundial e, em estudos realizados no Equador e no Rio de Janeiro, a sua prevalência foi de 1,43% e 1,63%, respetivamente. Não foram encontrados mais estudos relativos à prevalência de crises epiléticas no mundo e não existe nenhum estudo na população portuguesa.
Objetivo: O objetivo deste estudo é avaliar a prevalência de crises epiléticas em indivíduos com idade superior a 65 anos na área abrangida pelo Centro de Saúde de Manteigas e compará-la com a prevalência desta patologia noutros países.
Materiais e métodos: A recolha dos dados foi realizada através de uma entrevista clínica a voluntários previamente convocados por carta para comparecerem no Centro de Saúde de Manteigas e utilizando o questionário de Placencia M., orientado para a deteção de crises epiléticas em estudos de larga escala, validada em português. Nesta entrevista foram também recolhidas outras variáveis para estudo e comparação como o sexo, a idade, a naturalidade, a escolaridade e o setor de atividade profissional.
Resultados: Dos 368 indivíduos entrevistados, 123 tiveram critérios para serem definidos como positivos, resultando numa prevalência de crises epiléticas, na população em estudo, de 33,4% (IC-95%: 28,8-38,4%).
Discussão: Este valor é significativamente superior à prevalência de crises epiléticas verificada em três outros estudos do mesmo âmbito, mas realizados em populações diferentes. Esta discrepância será maioritariamente devida a limitações da aplicabilidade da escala para uma população alvo acima dos 65 anos de idade, mas também poderá estar relacionada com a diferente metodologia utilizada para a convocatória dos voluntários, ou com a existência de fatores genéticos, ou ambientais, ou outras patologias particularmente prevalentes em idosos, cujo estudo foge aos objetivos deste projeto, mas que, poderão vir a ser estudados e correlacionados com a ocorrência de crises epiléticas, num futuro projeto, para esta mesma população.
Introduction: An epileptic seizure is a clinical or a psychic manifestation of an abnormal cerebral neuronal process of electric hyperactivity and/or hypersynchrony which may affect the brain in a partial (focal), or generalized manner. It may also vary, from the shortest lapse of attention, or muscle spasm, to severe and prolonged convulsions. Epileptic seizures affect about 2 to 3% of the world population and, in studies in Ecuador and Rio de Janeiro, showed prevalence values of 1.43% and 1.63%, respectively. No other studies regarding the prevalence of epileptic seizures in the world were found and there are no studies in the Portuguese population. Objectives: The goal of this study is to analyze the prevalence of epileptic seizures in individuals older than 65 years of age within the area of Manteigas’s Healthcare Centre and to compare it with the prevalence of this pathology in other countries. Materials and methods: Data was collected using a clinical interview of volunteers who had been previously invited by post to come to Manteigas’s Healthcare Centre. In addition, the screening questionnaire by Placencia M. for the detection of epileptic seizures in a large scale survey, validated in Portuguese, was also used. In this interview other variables such as sex, age, nationality, education level and sector of professional activity were also collected for study and comparison. Results: Of the 368 individuals surveyed, 123 had criteria to be defined as positive, resulting in a prevalence of epileptic seizures of 33.4% (IC-95%: 28.8-38.4%), in this study population. Discussion: This value is significantly higher than the prevalence of seizures observed in three other studies with the same scope. This discrepancy could be mainly due to limitations of the applicability of the scale to a target population above 65 years of age but may also be related to the different methodology used to recruit the volunteers or the existence of genetic or environmental factors or other diseases particularly prevalent in the elderly, whose study does not follow the objectives of this project, but that might be studied and correlated with the occurrence of seizures in a future project for this same population.
