Introduction. The study is aimed at identifying emotional factors that determine the deficit of social perception in neurasthenia. Theoretical analysis. Insufficient knowledge of the phenomenology of neurasthenia and the difficulties of its differential diagnosis at the stage of pathological personality development is shown. The lack of targeted assistance to patients and their objectively rapid disability is emphasized. The hypothesis is formulated that patients with neurasthenia have a pronounced violation of social perception, determined by social anhedonia.
