A team of Seoul St. Mary’s Hospital investigators utilizing population health data, involving over 1 million patients over 10 years, found evidence of a 2X increase of mental health disorders associated with psoriasis. These mental health issues include:
- Depressive episodes
- Anxiety disorders
- Somatoform disorders
- Neurotic disorders
- Non-organic sleep
The St. Mary’s Hospital team sought to assess the average length of time for each of the six mental health comorbidities associated with patients post-psoriasis disorder. The team secured the data from the South Korea Health Insurance Research and Assessment Agency from the period 2002 to 2013.
Mental health disorders and psoriasis were identified by the investigators utilizing diagnostic codes. Overall, 12,762 patients were diagnosed with psoriasis. The following mental health disorders were most likely to develop in psoriasis patients, in order of most to least:
- Anxiety disorders 2.92
- Somatoform 2.62
- Neurotic 2.66
- Non-organic sleep disorder 2.58
It is not clear if these findings are transferable to the United States, where approximately 8 million struggle with psoriasis. The American Academy of Dermatology (AAD) is on record that psoriasis can increase the risk of “mood disorders,” which is what prompted the Korean study.
