[Psychiatric comorbidities of psoriasis: pilot study]

Area of Science:

• Psychiatry
• Dermatology
• Psychology

Background:

• Psoriasis is a chronic skin disease with reported associations with depression.
• Previous hypotheses suggest interactions between psoriasis and mental health, but lack empirical validation through structured psychiatric interviews.
• There is a need to rigorously assess mental health comorbidities in psoriasis patients.

Purpose of the Study:

• To compare the frequency of depression in patients with psoriasis versus those with other chronic skin diseases.
• To utilize the Mini International Neuropsychiatric Interview (MINI) for standardized mental disorder diagnosis.
• To investigate the prevalence of affective and anxiety disorders in psoriasis.

Main Methods:

• A comparative study involving 32 psoriasis patients and 32 controls with other chronic skin diseases.
• Psychiatric assessment using the Mini International Neuropsychiatric Interview (MINI).
• Evaluation of depression severity using the Beck Depression Inventory and Hamilton Rating Scale for Depression, and neurotic symptoms via the Symptoms Check List-II.

Main Results:

• The point prevalence of mental disorders was significantly higher in the psoriasis group (62.5%) compared to the control group (15.62%).
• Affective disorders were diagnosed in all affected psoriatic patients, with mild anxiety disorders also found more frequently.
• Psoriasis patients exhibited significantly higher depression scores and neurotic symptom intensity.

Conclusions:

• Psoriasis patients demonstrate a substantially elevated risk for mental disorders, particularly depression.
• The findings underscore the importance of routine mental health evaluations for individuals with psoriasis.
• Prompt identification and treatment of psychiatric comorbidities are essential for comprehensive patient care.
