Abstract

Background This study investigated the incidence of current poststroke dementia (PSD), the annual conversion ratio into PSD, and the risk factors for conversion. Methods In a 4.8-year follow-up period, 112 poststroke patients (ischemic stroke and intracerebral hemorrhage) were retrospectively investigated in cognitive examinations. They were categorized into 3 subgroups: converters into PSD, nonconverters who maintained their normal cognitive functions, and reverters who recovered to the normal mentality range. The clinical and demographic characteristics of these 3 subgroups were analyzed. Results Among all 112 poststroke patients (61.6% male, 73.6 ± 10.4 years old), 16.1% had PSD. During the follow-up period, a part of the normal baseline mentality group (83.9% of 112 original patients) newly developed PSD (subdivided into converters) with an annual conversion rate of 7.6%. The reversion rate from the baseline PSD group was 11.3%. There were significant differences in age (P
