Ten years ago, a famous old professor of dermatology told the following true story in a "symposium of dermatologists and patients with psoriasis". There was a female patient with psoriasis from other places to Beijing to be hospitalized for psoriasis, after more than 30 days of careful treatment and care by doctors and nurses, psoriasis skin lesions basically subsided. The old professor told her that she could be discharged within this week, and the patient was very happy. Unfortunately, in the afternoon, she received home to send an "urgent telegram", the content of the telegram is: "mother critically ill and soon home". The patient immediately rushed to the Beijing railway station to buy a ticket home, only to find that not only there was no ticket for the night, but also no ticket for three days. The patient took out the "urgent telegram" to the conductor and asked the conductor to take care of it. The conductor was too busy selling tickets to take into account the patient's request and casually said: "Now there are too many fake telegrams to take care of". Hearing this, the patient was angry and anxious, so he went to see the person in charge of duty at the railway station. The answer he got made him even sadder: "You said that your mother was ill, and he said that his father was ill. Today, several people have come to buy train tickets with telegram, who knows whether you are true or false. The patient had no choice but to go back to the hospital. After arriving at the hospital, she lay on the bed, covering the quilt and crying for a long time. She did not eat her supper, and could not sleep all night. The next day, the attending doctor made rounds and found that the patient had a lot of small red papules in the area that had subsided, and the psoriasis rash had recurred... At the end of the story, the old professor said with deep feeling that the lady's psoriasis had just been cured and suddenly recurred overnight, which was closely related to her mood and mood.

        Clinicians found that people with the following personality characteristics are prone to psoriasis :(1) people with depression, anxiety and more easily frightened type of personality. In fact, in our daily life, depression, anxiety or panic, all of these are everyone some mental performance, but there are some psychological adaptability is poorer, the same thing, ordinary people won't appear this kind of condition, this kind of person first appeared, and in this state for a long time may will induce psoriasis. (2) People with poor psychological bearing capacity and personality type: people with poor psychological bearing capacity tend to be those with relatively superior living conditions, especially those who are regarded as the treasure in the family. They are difficult to bear excessive pressure after things happen, and once experienced, they will be at a loss, which will easily cause depression, anxiety and panic. (3) Poor adaptability to negative events: People with such personality characteristics tend to have better living conditions than ordinary people, especially in their teenage years. They have excellent living conditions since childhood, lack experience of negative events, and are self-centered in everything.

        Medical tests have shown that certain personality characteristics are highly sensitive to internal and external environmental stimuli. When subjected to a certain degree of negative social events, intense emotional changes will occur, resulting in the disorder of the autonomic nervous system activity and immune function of the body, and ultimately leading to psoriasis.
