I have no idea, but with ADHD and all, I have taken recently the habit of reading aloud, especially course texts, doc’s and other boring stuff I easily get distracted with. I pretend to be a BBC 4 broadcaster. It seems to work. After awhile you can stop and just read silently.
fellow ADHD. if you read in a place with no distractions, you can read silently, and fast for a long time.
