Study on the relationship between sleep–wake states and prognosis in patients with intracranial arterial stenosis and ischemic stroke

The sleep-wake state of patients with intracranial artery stenoischemic stroke changes. The main characteristics are increased diurnal sleep, increased incidence of daytime sleep, and disordered sleep-wake phases. In patients with ACIS, the diurnal sleep-wake biological rhythm mainly characterized by poor daytime stability is unbalanced. The longer the duration of daytime deep sleep and nighttime NREM sleep, the higher the possibility of adverse outcomes in patients with intracranial artery stenotic ischemic stroke.
