Link psoriasis and sleep apnoea

I've had quite extensive psoriasis for the last 8yrs. Creams etc don’t seem to help. Just after Christmas I was diagnosed with sleep apnea and started CPAP treatment. From day 1 of this my psoriasis started clearing up. Monday I had a dermatology appointment and showed my consultant. He said he knew there could be a link between the two. When I investigated for myself, there have been several studies done on this and the recommendations were to screen people with psoriasis for sleep apnea. In all my years of treatment, this has never been mentioned! Please may I suggest that if you have psoriasis and sleep problems or feel constantly tired that you take the Epworth Scale test for yourself and if your score recommends, you contact your GP and ask to be tested for sleep apnea. Honestly this has been a complete game changer for me.
