Abstract

Prior studies have shown high prevalence of neuropsychological deficits after aneurysmal subarachnoid hemorrhage; however, few studies detect cognitive impairments in patients with good functional outcome, measured whith Rankin Modified Scale, in the late phase of subarachnoid hemorrhage. We confirmed a high prevalence of alterations in neuropsychological tests in 44 patients with Rankin Modified ≤ 2. We proposed the application of simple and fast tests that allowed us to detect impairments with precision similar to that of complex cognitive batteries used in previous studies. We also attempt to confirm statistical association between factors that could be related to poor cognitive outcome, like Hunt-Hess scale classification, bleeding intensity measured with Fisher scale, therapeutic type (microsurgery ou embolization), and aneurysm localization; however, there was no significance.

Resumo

Estudos anteriores mostraram que a prevalência de déficits neuropsicológicos após hemorragia subaracnóide aneurismática é alto, mas poucos estudos detectaram alterações cognitivas em pacientes com bom desfecho funcional, medido através da escada de Rankin Modificada, na fase tardia da hemorragia subaracnóide. O estudo confirmou em 44 pacientes com RankiN Modificado ≤ 2 a alta prevalência de alterações em testes neuropsicológicos. Propusemos a aplicação de testes simples e rápidos, capazes de detectar alterações, com precisão semelhante a baterias cognitivas complexas utilizadas em estudos anteriores. Nós também avaliamos a associação estatística entre alguns fatores como a escala de Hunt-Hess (HH), a intensidade do sangramento pela escala de Fisher, tipo de tratamento (microcirurgia ou embolização) e localização do aneurisma, ao pior desempenho cognitivo, no entanto não houve significância.
