The typology of the objective disorders of night sleep in insomnia
: The most frequent polygraphic manifestations of insomnia were analysed in 39 neurotic patients with disorders of night sleep (NS). The frequency of pathological alterations of the objective characteristics of NS was determined after examination of the data obtained. Four types of sleep alterations were recognized. There was not always clear correlation between the subjective estimation of sleep and its objective characteristics. For choice of optimal therapeutic policy it was proposed to evaluate leading complaints of the patients for more accurate definition of the degree of expression of objective manifestations of insomnia without usage of NS polygraphy. Possible mechanisms of NS disorders were determined. Classification of different types of objective disorders of sleep in insomnia was elaborated.
