Psychiatry to dermatology; panic disorder.

OBJECTIVE

Anxiety is commonly observed together with skin diseases and can aggravate them, while skin diseases can increase anxiety. The relationship of skin diseases observed in panic disorder with quantitative electroencephalography (QEEG) findings has not been investigated yet. The aim of this study is to compare the absolute alpha and delta power of panic disorder patients with and without skin disease.

METHODS

246 panic disorder patients, 19 of whom had skin disease and 227 of whom did not have skin disease, were included in the study. Panic disorder severity scale (PDSS) scores of patients were recorded, and QEEG recording was performed. Absolute alpha and delta power and PDSS scores were compared between the two groups.

RESULTS

It was found that the absolute delta power in the left hemisphere was lower and PDSS scores were higher in the patients with skin diseases compared to the control group. In the patients with skin disease, decreased delta power in the left hemisphere may cause impairment in the processing of positive emotions and may cause trait anxiety.

CONCLUSION

Trait anxiety may increase susceptibility to skin diseases by disrupting cutaneous homeostasis resulting from the prolonged sympathetic nervous system activation.
