Patients with mood depression have a high prevalence of seborrhoeic dermatitis.

Paper Abstract

Prevalence and severity of seborrhoeic dermatitis were studied in 150 patients with psychiatric disorders, including schizophrenia, mood disorders, anxiety and organic mental illness. As a control group, we examined 150 patients waiting for surgery and regarded as obviously anxious. Thirty-eight psychiatric patients were found to have seborrhoeic dermatitis, versus 13 in the surgery group. This statistically significant difference was entirely ascribable to patients with depression.
