Neurocognitive sequelae of stroke create a significant impact on the patient and frequently disrupt recovery from the physical manifestations. This article strives to review types of neurocognitive changes after stroke and discuss the underlying pathophysiology. Management options are presented for the diverse changes that may be encountered.
The modern stroke unit is making significant contributions to the care of stroke victims and is proving to be an effective, cost-saving enterprise. The precise factors that contribute to the efficacy of these units have yet to be identified, but a combination of protocolized approaches to patient care, critical paths, a focus of expertise, and heightened index of suspicion for comorbidities all probably play a role. This article outlines the basic features of a modern stroke unit and surveys the literature on stroke unit outcomes.
Strokes are focal lesions in the brain and as such bring about deficits and portend a course of recovery depending on the nature of the lesion. Given the large number of possible combinations of locations, sizes, and types of lesions, a clear and reliable formula for predicting outcomes based on these characteristics has been statistically difficult, particularly early in the course of recovery. Severity of deficit and age of the patient accounts for sufficient variability that the influence of other factors becomes statistically harder to illustrate.
