A model of poststroke fatigue based on sensorimotor deficits.

PURPOSE OF REVIEW

This review examines recent studies in poststroke fatigue that might contribute in understanding the pathophysiology of poststroke fatigue. Poststroke fatigue is a common problem in stroke survivors. Little is known about the pathophysiology of chronic fatigue in stroke survivors. It has long been thought of as a neuropsychiatric problem. However, there is gathering evidence to the contrary. In this study, we propose a new model of poststroke fatigue based on recent findings of corticomotor neurophysiological, behavioural, and perceptual deficits in the poststroke fatigue population.

SUMMARY

The current evidence suggests that poststroke fatigue may not be a neuropsychiatric problem but a problem of the sensorimotor system. Future studies need to address the causal link between sensorimotor deficits and poststroke fatigue.
