Abstract TP568: Predictors of Long-Term Impaired Processing Speed After Stroke

Background and Aims: Impaired Processing Speed (IPS) affects up to 50 to 70 % of stroke survivors and has a major influence on post-stroke cognitive dysfunction, affecting quality of life and increased dependence on others. Few studies have examined predictors of IPS after stroke, and there is a paucity of data in terms of long-term prevalence. This study examined baseline predictors associated with long-term impaired processing performance in an existing population-based cohort, four years after stroke. Method: IPS was assessed using the Symbol Digit Modalities Test (SDMT), at four years after stroke in a sample drawn from an existing population-based study (n=133, mean age =67.0 ± 13.4). Baseline predictors were obtained at time of stroke and/or within two weeks of the acute event. Multivariate linear and logistic models were used to identify baseline predictors (reported as OR with 95%CI) and prevalence of long-term IPS. Results: Four years after stroke 62% of survivors had IPS indicated by a mean scor...
