Sleep-disordered breathing (SDB ex. obstructive sleep apnea) has been found to be an independent risk factor for stroke. SBD and sleep-wake disturbances (SWD) increase the risk of stroke AND may impair neuroplasticity and recovery of function AFTER a stroke.
Sleep studies should be completed in patients with stroke or warning signs of stroke in the form of TIA's.
