[Symptoms of circadian desynchronization in patients with multiple sclerosis].

Circadian rhythm of sleep-wakefulness and evacuation function of intestines, symptoms of neuropsychic adaptation were investigated in 36 patients, aged 21-53 years, with multiple sclerosis (MS). Frequencies of circadian rhythm disturbances of brain activity (insomnia in 66% of patients) and circadian rhythm disturbances of intestine evacuation (constipation in 72% of patients) were revealed. Insomnia and irritability in MS patients with bradyenteria occur 1.5 times more frequent than in patients with normal regulative activity of the bowels. The risk of anxiety and depression in MS patients with bradyenteria was 2-3 times higher than in patients with euenteria. The suitability of normalization of circadian desynchronization of MS patients by the restoration of optimal acrophases of circadian rhythms of the brain and bowels is established.
