Dementia affects a person’s adaptation in everyday life, social life and usually affects a professional quality. Caring for patients with dementia causes distress to their family members. In modern psychiatric practice, a multi-vector approach is used within the biopsychosocial model of care for dementia patients. The leading strategy for the treatment of this category of patients includes measures to prevent development of cognitive deficits and, of course, treatment as itself. The main components of treatment are pharmacotherapy, psychotherapy and psychoeducational interventions aimed at people who provide care for patients. A comprehensive program of medical and psychological rehabilitation developed for patients with dementia includes the following components: pharmacotherapy, psychotherapy, psychoeducation (for patients and their relatives), psychological training (training of communicative, cognitive, social skills).
