Patients with mood depression have a high prevalence of seborrhoeic dermatitis

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.
