The role of anger, type D personality, and alexithymia in the pathogenesis and process of psoriasis: a narrative review

Clinical route of many dermatologic diseases is due to the mutual and complex interactions between biological, psychological, and social causes that can affect them as predisposing, accelerating, or enduring factors. Psoriasis is one of the most common autoimmune skin diseases with psychosomatic origins and consequences, which is accompanied by vulnerability to stress, emotional disorders, and difficulty in expressing negative feelings. Many psoriasis sufferers have problems in how much they experience anger and how to express and control anger. Two components of D personality including, negative emotionality, social inhibition, and emotional ataxia seem to be important in psoriasis. Due to the neglect of clinical researches and organized attention to the investigation and improvement of the psychological factors of this disease, a more comprehensive explanation of the occurrence of this disease with a more targeted interaction and integration of medical and psychological perspectives is nessesary. Theorethical and practical conjunction between dermatologists, psychologists and psychiatrics in the interdisciplinary field of psychodermatology can lead to maintain higher health services for psoriatic patients as well as achieving scientific outcomes.
