Prevalence of Cognitive Impairments in Patients with Good Functional Outcome in Late Phase Subarachnoid Hemorrhage Prevalência de alterações cognitivas em pacientes com bom desfecho funcional na fase tardia da hemorragia subaracnóidea

► cognition ► embolization ► therapeutic ► microsurgery ► clinical evolution Abstract Prior studies have shown high prevalence of neuropsychological deficits after aneurys- mal 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 confirmeda 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 mea- sured with Fisher scale, therapeutic type (microsurgery ou embolization), and aneu- rysm localization; however, there was no significance.
