The role of psychological factors and serum zinc, folate and vitamin B12 levels in the aetiology of trichodynia: a case-control study.
Cutaneous dysaesthesia syndromes are characterized by chronic cutaneous symptoms without objective findings, and their aetiologies are obscure. Trichodynia describes pain and a stinging sensation of the scalp related to diffuse alopecia. ⋯ Trichodynia is a commonly encountered symptom in patients with diffuse alopecia, and depression and somatoform dissociation disorders may play an important role in its aetiology. Our data provide no evidence that serum levels of zinc, folate or vitamin B(12) are involved in the pathogenesis of trichodynia.
