ABSTRACT
ABSTRACT

Background:

Nonconvulsive status epilepticus (NCSE) is a condition that needs timely diagnosis and treatment. It has insignificant clinical features and presents high risk of misdiagnosis.

Objective:

To investigate NCSE among patients with stroke, given that stroke plays an important role in the etiology of NCSE.

Methods:

In this retrospective study, acute stroke patients who were admitted and followed up at a stroke outpatient clinic between January 2013 and March 2016 were included. Patients with previous histories of epilepsy, brain tumor, head trauma, hypertensive encephalopathy, arteriovenous malformation, subarachnoid hemorrhage or cerebral venous thrombosis were excluded. Demographic properties, stroke etiology, imaging method, EEG findings, stroke severity according to the NIHSS score, functional disability and modified Rankin Scale were recorded for all patients.

Results:

Thirty-nine out of 792 stoke patients experienced NCSE. The mean age of the study population was 70±1.2 years (min-max 46‒90). The study population was composed of 28 females (71.8%) and 11 males (28.2%). NCSE had early onset in 23 patients (59%) and late onset in 16 (41%). The early-onset NCSE patients were older and this was statistically significant between the groups (early onset 73.5±11.5; late onset 65.9±12.1; p=0.04). A history of previous stroke was more frequent in the late-onset NCSE group (14; 87,5%) than in the early-onset group (11; 47.8%) (p=0.01). The prognosis was worse in the early-onset group, but without statistical significance.

Conclusion:

Changes in mental status in the early stages of stroke are mostly attributed to stroke itself, but NCSE should be suspected in the right clinical setting, such as in older patients with suspicious anatomical and clinical associations.
RESUMO
RESUMO

Introdução:

O Estado de Mal Não-Convulsivo (EMNC) é uma condição que necessita de diagnóstico e tratamento oportunos. Possui características clínicas insignificantes e apresenta alto risco de diagnóstico incorreto.

Objetivo:

Investigar o EMNC entre pacientes com acidente vascular cerebral (AVC), visto que ele desempenha um papel importante na etiologia do EMNC.

Métodos:

Neste estudo retrospectivo, pacientes com AVC agudo que foram admitidos e acompanhados em um ambulatório de AVC entre janeiro de 2013 e março de 2016 foram incluídos. Pacientes com história prévia de epilepsia, tumor cerebral, traumatismo cranioencefálico, encefalopatia hipertensiva, malformação arteriovenosa, hemorragia subaracnóidea ou trombose venosa cerebral foram excluídos. Propriedades demográficas, etiologia do AVC, método de imagem, achados de EEG, gravidade do AVC pela escala NIHSS, incapacidade funcional e escala de Rankin modificada foram registrados para todos os pacientes.

Resultados:

Um total de 39 dos 792 pacientes com AVC experimentaram EMNC. A idade média da população do estudo foi de 70±1,2 anos (mín-máx 46‒90). A população do estudo foi composta por 28 mulheres (71,8%) e 11 homens (28,2%). O EMNC teve início precoce em 23 pacientes (59%) e início tardio em 16 (41%). Os pacientes com EMNC de início precoce eram mais velhos, o que foi estatisticamente significativo entre os grupos (início precoce 73,5±11,5; início tardio 65,9±12,1; p=0,04). Um histórico de AVC prévio foi mais frequente no grupo com EMNC de início tardio (14; 87,5%) do que no grupo de início precoce (11; 47,8%) (p=0,01). O prognóstico foi pior no grupo de início precoce, mas sem significância estatística.

Conclusão:

As alterações no estado mental nos estágios iniciais do AVC são atribuídas principalmente ao próprio AVC, mas deve-se suspeitar de EMNC com diagnóstico clínico correto, como em pacientes mais velhos com associações anatômicas e clínicas suspeitas.
