[The medical significance of loneliness and social isolation in old age (literature review).].

Communication is considered as one of the basic human needs. For a long time, loneliness and social isolation were mainly considered as a psychosocial problem. However, in the recent years, there has been increasing evidence of the possible impact of loneliness and social isolation on the development and clinical course of somatic diseases. Research objectives were studying and analysis of current literature data about the medical consequences of loneliness and social isolation in the elderly cases. An analysis of the literature data shows that loneliness and social isolation affect not only the psycho-emotional status of elderly patients, but also their physical health. It has been shown that the number of available social connections affects the development and clinical course of diabetes mellitus, cardiovascular diseases, and outcomes of the brain stroke, immune system reactions, average life expectancy, and the risk of death caused by any causes. It has been established that the influence of social ties on the risk and clinical course of chronic non-communicable diseases is comparable to the effect of such generally accepted risk factors like smoking, alcohol consumption, physical inactivity, hypertension, obesity, hypercholesterolemia, environmental pollution, as well as various medical interventions (vaccination, drug therapy, etc.). Social isolation affects the risk of hospitalization and the frequency of outpatient care, poor socialization increases the risk of death from a heart attack. The results of the study show that loneliness and social isolation of the elderly cases have certain medical consequences that need to be taken into account when managing such patients.
