I was diagnosed with ADHD in adolescence. Since then it has always taken an enormous amount of pressure and energy for me to perform tasks that require focused attention. However, recently I was diagnosed with sleep apnea and started CPAP treatment. To my surprise, my ADHD symptoms greatly improved. I wish I had gotten a sleep study decades ago.

I’m sure the causes of ADHD are varied and complex so this won’t work for everyone, but just in case, you might want to get a sleep study.

Edit: I originally wrote that I “developed ADHD in adolescence”. I changed it because I had not intended to comment on whether ADHD is innate or acquired. I also changed “my ADHD went away” to “my ADHD symptoms greatly improved” for the same reason.

Note: Maybe it will be helpful if I give some context about what “ADHD” means to me. I’ve always thought of it as my brain working differently than most people. The most obvious characteristic has been that things most people consider “easy” like doing the dishes were entirely impossible for me to do in a timely fashion. I also struggled in school because I couldn’t get my homework done and I couldn’t study.

People, including my parents and teachers would all say things like “you’re not trying hard enough” or “you’re not applying yourself”. I tried, and failed, to explain that there was no amount of effort I could summon that could switch my brain into this steady productivity mode that other people could seemingly just turn on at will.

When I was a little kid, no one outside of maybe some academics had ever heard of ADHD, so my struggles were misunderstood and “my fault”. In my case, the hyperactivity symptoms were less prevalent, but I sometimes did annoying, obnoxious things.

I first heard of ADHD (just called ADD at the time) when I was a teenager. But there was still a big stigma around it and most people didn’t think it was a real condition, so I didn’t get treatment.

When I was a young adult, I finally got treated and prescribed stimulant medication. The medication made it possible for me to switch my brain into that steady productive mode, but it also had a lot of side effects.

Now, in middle age, my doctor suggested I have a sleep study due to some other symptoms I was having. So I did and they diagnosed me with sleep apnea with hypoxemia and prescribed CPAP treatment. After starting treatment I began to notice that I was able to switch my brain into that steady productive state even without medication. I began to wonder if sleep apnea (or perhaps more precisely nocturnal hypoxemia) had been the underlying cause of my symptoms all along.

Today, I saw an ADHD meme from another community and that prompted me to look up this community and share in case someone else could benefit from similar treatment. It had never occurred to me that there could be a connection between sleep apnea and ADHD symptoms until I tried the CPAP.

Like I said, I don’t suspect this will help everyone, but if there’s one person like me out there who it does help, I think it’s worth sharing.
