Neurosis, also known as neurotic disorder, is a mental disorder related to psychosocial factors and is also associated with the patient's personal personality traits.

The clinical manifestations include feelings of tension and anxiety, and may be accompanied by insomnia and symptoms of autonomic nervous system dysfunction. Some patients may present with obsessive - compulsive symptoms or symptoms of somatization disorder.

Patients have obvious subjective symptoms that vary greatly, but there is a lack of objective evidence to support them.

Generally, psychological therapy and medication are required.
