DISORDERS OF SLEEP STRUCTURE AND AUTONOMIC REGULATION IN THE SLEEP OFPATIENTS WITH STROKE

Peculiarities of both the structure of night sleep and autonomic regul ation in the sleep were studied in 30 patients with ischemic stroke of different location. Clinical, polysomnographic (including autonomic i ndices) and psychologic methods were used, Considerable alterations in the structure of night sleep were observed, namely: lengthening of th e period of falling asleep, increase of the time of awakening inside t he sleep, impossibility to support necessary duration of both stages a nd phases of sleep. The indices of cardiovascular system's activity su ch as heart rate (HR) and arterial pressure (AP) were altered most of all, The most dramatic disorders of both the structure of sleep and au tonomic regulation in the sleep were found in right hemispheric and me dial location of ischemic stroke. High values of HR and AP in the slee p (especially in phase of the fast sleep), high HR and AP variability as well as the decrease of these indices from the first cycle of the s leep to the third one were prognostically unfavourable factors.
