Behçet's disease is a rare, chronic inflammatory condition that causes recurrent mouth and genital ulcers, eye inflammation, skin lesions, and joint pain, driven by inflammation of blood vessels throughout the body. It typically begins in young adulthood, follows an unpredictable course of flares and remissions, and is most common in Turkey, the Middle East, and East Asia along the historic “Silk Road.”
A 2007 study published in the International Journal of Dermatology compared people with Behçet's disease directly against people with psoriasis, another visible chronic skin condition, and found that Behçet's disease carries a substantially heavier psychological burden. Understanding just how much heavier, and why it seems to get worse the longer someone lives with the disease, is an important step toward getting the right kind of support early.
What the Research Shows
Researchers compared 112 people with Behçet's disease against 95 people with psoriasis, using standardized questionnaires measuring depression, anxiety, negative automatic thoughts, and hopelessness. The Behçet's disease group scored significantly higher than the psoriasis group on every single measure. Almost one-half of the patients with Behçet's disease had depression. Overall, having Behçet's disease increased the risk of depression four-fold compared with having psoriasis — and among those who had lived with the disease for more than three years, that risk climbed to twelve-fold. The longer someone had the illness, the higher their depression, negative-thinking, and hopelessness scores tended to be, a pattern that was not seen at all in the psoriasis comparison group.
Ways to Cope With Behçet's Disease
- Ask for a psychological check-in early, not just when things feel unbearable. Because risk climbs with duration of illness, getting support soon after diagnosis, rather than waiting years, may help prevent the heaviest burden from building up.
- Track your flares and your mood together. Behçet's disease often comes in unpredictable bouts. Noticing how your mood shifts around flares can help you and your care team anticipate rough patches and plan support in advance.
- Connect with a rheumatologist experienced in Behçet's disease specifically. Because it is rare, general practitioners may take time to recognize it. A specialist who understands its full-body nature can also make mental health referrals more confidently.
- Don't dismiss persistent low mood as “just” a reaction to symptoms. The research shows this is a measurable, well-documented risk tied to the illness itself, not a personal weakness, and it deserves its own dedicated treatment.
- Build a support routine around flare-ups. Painful mouth and genital ulcers can make ordinary daily life, including eating, intimacy, and going out, much harder during a flare. Planning gentle, low-pressure routines for these periods can reduce added stress.
Anxiety Is Common Too, Not Just Depression
A separate study of 73 people with Behçet's disease used a gold-standard structured clinical interview, the kind a mental health professional would use to make an actual diagnosis, rather than a self-report questionnaire alone. It found that 41.1% had at least one diagnosable psychiatric disorder at the time of the interview. Major depression was the single most common individual diagnosis, at 17.8%, but anxiety disorders were common too: 16.4% had a specific phobia, 15.1% had generalized anxiety disorder, and 9.6% had social phobia. Both any psychiatric disorder and anxiety disorders specifically were significantly more common among women than men with Behçet's disease in this study.
You Don't Have to Carry This Alone
Because Behçet's disease is an unpredictable, lifelong autoimmune condition, many of the coping approaches that help with other ongoing illnesses apply here too — our guide to Living with Chronic Illness or Pain is a good starting point. The joint pain and painful ulcers that come with flares can be significant on their own, and our resource on Coping with Chronic Pain offers additional tools for that. The visible skin lesions and oral or genital ulcers Behçet's disease can cause may also affect how you feel about your body, which our page on Body Image speaks to directly. And because this study specifically compared Behçet's disease with psoriasis, another chronic skin condition with its own mental health toll, our page on Psoriasis and Mental Health is a natural companion resource.
Tips for Supporting Someone With Behçet's Disease
- Learn that this is a whole-body disease, not “just” mouth sores. Behçet's disease can affect the eyes, joints, skin, digestive system, and in serious cases blood vessels and the nervous system. Understanding its full scope helps you appreciate what your loved one is managing.
- Check in especially as time goes on. Because psychological risk rises the longer someone has lived with the illness, don't assume that someone who has “had it for years” has adjusted and no longer needs support — the research suggests the opposite may be true.
- Be sensitive around ulcer flares. Painful mouth and genital ulcers can make eating, speaking, and intimacy difficult and can feel embarrassing to discuss. Offer practical help without requiring detailed explanations.
- Don't compare it to more familiar conditions. Because Behçet's disease is rare, well-meaning comparisons to other illnesses can feel dismissive. Take time to learn about it on its own terms.
- Encourage professional mental health support without pressure. Given how common depression and anxiety are with this condition, gently normalizing therapy or counseling as part of overall care, rather than a last resort, can make a real difference.
