In ICD-10, the diagnosis of neurasthenia requires the following: 1) persistent and painful complaints of “tiredness after using the brain”; or persistent and painful complaints of “weakness and extreme fatigue after light exertion”; 2) the presence of at least two of the following At least two of the following: (1) muscle pain; (2) dizziness; (3) tension headache; (4) sleep disturbance; (5) inability to relax; (6) irritability; (7) indigestion. 3. Any co-existing autonomic symptoms or depressive symptoms do not meet the criteria for more specific disorders in this classification system in terms of severity and duration.

According to the principle of hierarchical diagnosis, the disorder can be diagnosed only if other psychiatric disorders are excluded.
