Objective. To identify the differences in the level of subjective well-being in adult people in the process of refining and establishing the diagnosis of epilepsy. Material and methods. The study enrolled in total 67 people, including 37 patients, aged from 24 to 51 years, referred to the epileptologist to refine the diagnosis of epilepsy, 15 age-matched healthy controls and 15 age-matched controls with neurological diseases. The Subjective Well-Being Scale modified by M.V. Sokolova was used. Results and conclusion. An individual experiences negative emotional feelings during the process of refining and establishing the diagnosis of epilepsy, which are strengthened by the specifics of dysphoric disorders in epilepsy. This decreases the level of self-reported subjective well-being that is convincingly confirmed by psychodiagnostic methods.
