Abstract

Objective: To study the prevalence of anosognosia for hemiplegia (AHP) in the hyperacute phase and track the natural history of the disorder, in order provide a more complete account of the phenomenon. Background Anosognosia for hemiplegia (AHP) after stroke contributes to clinical morbidity and poor outcome in several different ways, beginning at the time of acute injury (the hyperacute phase) and continuing through the course of the illness. AHP is the behavioral response to sudden hemiplegia in 33-58% of patients and has been found to be associated with longer rehabilitation and poorer functional outcomes following stroke. Despite the pragmatic implications, relatively little is known about the natural history and neuropsychological basis of AHP. Design/Methods: We assessed patients in the acute phase and subacute phase of stroke with serial neuro-cognitive exams. Enrolled patients underwent serial neurological and neuropsychological examinations while on our stoke unit. The neuropsychology battery included a detailed awareness interview (including the Bisiach and Feinberg Scales) and neglect batteries performed in the hours and days after stroke. Results: Of the 28 patients enrolled, AHP was frequent at 28% in the hyperacute phase ( Conclusions: Anosognosia for hemiplegia is a transient phenomenon that tends to dissipate with time, and thus it9s reported frequency and presentation may vary depending on when patients are evaluated. Although there is rapid improvement in explicit recognition of hemiplegia, the fact that AHP remains an independent predictor of poor functional recovery underscores the need to further understand the underlying mechanism of the disorder, and how it contributes to a poor global functional recovery.
