The association between stress and psoriasis is well documented. A subgroup of psoriatic patients appear to be high stress reactors who can identify specific psychosocial stresses which exacerbate their psoriasis. In contrast, low stress reactors report no association between stress and the exacerbation of psoriasis. In differentiating high versus low stress reactors, a review of the literature suggests: 1) a neurogenic mediated disease process; 2) high stress reactors' disease course is not confounded by underlying psychopathology and, 3) high stress psoriatics experience more disease related stress than low stress reactors.
