The role of neuropsychiatric factors in the occurrence of psoriasis / 中华皮肤科杂志

ABSTRACT

Considerable evidence has indicated that psychological factors,such as anxiety,nervousness and mental stress,can induce or exacerbate psoriasis and affect therapeutic effects to a certain degree,suggesting that psychological factors may play an important role in the occurrence of psoriasis.Current researches on neuropsychiatry-related pathogenesis of psoriasis mainly include two aspects:on the one hand,acting as stressors,psychological factors can activate the following two neuroendocrine systems,including hypothalamic-pituitary-adrenocortical axis and sympathetic-adrenal medullary system;on the other hand,neuropeptides and nerve growth factors induce in vivo neurogenic inflammation.Neuropsychiatric factors may participate in the occurrence of psoriasis through the above pathways.
