The article mentions sleep, which is very important to us all. But something not mentioned is that the symptoms of Sleep Apnea can look a lot like ADHD, and if you have sleep apnea and ADHD then you get a double whammy. Sleep apnea can start at any age, which could be one reason why your attention suddenly got worse. If you're waking up unrested, or have any of the other signs of sleep apnea, get it checked out. In my case my doctor resisted testing "because I wasn't obese," (more or less, perhaps I'm being unkind), so you may have to work at it. But an in-lab sleep study will give you a clear diagnosis. I have seen reports of people who were able to stop ADHD medication once their apnea was treated.
