### input:
My son, 23 years old is a suspected drug user. Marijuana and Methanphetimine. He also suffers from asthma and allergies and chronic psoriasis and ADHD . He can never sit still or stop fidgeting and he itches all of the time to the extent that it is hard for him to get a job because of these symptoms. He also has a hard time expressing himself verbally. He is high strung and very aggitated all of the time. We have Kaiser insurance but his Dr. says there is nothing he can do about the psoriasis, there is no cure. He is a very stressful individual and is having relationship problems. It s hard to talk to him without getting him all defensive. I ve read somewhere that stress can be a factor in psoriasis outbreaks. Is this true? YYYY@YYYY

### output:

Hi, Thanks for writing in.  Psoriasis is caused by genetic and autoimmune factors.  Stress can aggravate psoriasis. Keeping the stress levels low is key to treatment of psoriasis. Effective oral and topical medications are now available for Psoriasis. Psoriasis can be kept under control and patient can have long-standing remissions free of psoriasis skin lesions. My advice to you would be to use topical steroid with good moisturizer.  Few treatments like PVA therapy and phototherapy can help to treat psoriasis effectively. Consult a good dermatologist who can provide you with these options along with effective oral prescription medicines. Remember psoriasis can be controlled very effectively but cannot be completely cured. Hope this helps. Regards Chat Doctor.
