If you're not sure which came first then your ADHD-like symptoms could possibly be a result of your ED. Malnutrition can definitely affect your brain function. I'm not a psychologist or psychiatrist so I don't know. Have you been thoroughly tested or evaluated by a psych? If not, then you should look into getting tested when you're farther along in your ED recovery. Do you have trouble concentrating on doing things that you're interested in? If you do, that's a strong sign of ADHD. Another thing I've noticed about ADHDers is that we don't get hyper when we drink coffee. It's hard to describe ADHD in a nutshell. PM me if you have any questions. Good luck.
