Patient: Description of condition (time of onset, main symptoms, hospital visited, etc.): Hello Dr. Xu! I had a psychological consultation at the local psychiatric department some time ago, and the description of my psychological condition ended with incomplete self-awareness. Ask you if there are any problems? Quanzhou Third Hospital Psychiatric Department Xu Guoan: Self-knowledge (insight), also known as comprehension or introspection, refers to the patient’s ability to recognize and judge his or her own mental illness. In clinical practice, self-awareness is generally restored by the disappearance of psychiatric symptoms and the recognition that one’s psychiatric symptoms are pathological. Patients with neurosis have self-knowledge and actively seek medical advice about their condition. However, psychiatric patients generally have varying degrees of self-knowledge deficits, and they do not perceive a disease, much less acknowledge a psychiatric condition, and thus refuse treatment. The presence or absence of self-knowledge and the degree of recovery of self-knowledge are clinically important indicators for determining the severity of the illness and the degree of improvement of the disease. Complete self-knowledge is one of the most important indicators of recovery from psychosis. Lack of self-knowledge is unique to psychosis.
