Has he been diagnosed with ADHD? I am not for medication but if it helps him in general then that may be a good thing.
I have a habit of stomping in for the kill and it ends in misery. I have to learn to sit back and think about it. I think it comes about due to some anxiety problem that I have. Try getting him to stop and think. Maybe after his opponent moves he has to wait a minute before he can move again. During this time he could make a list of the current position and best moves. If he followed a methodical left to right pattern across the board, noting positions, threats and best moves; that may help him make better decisions. This is something I am trying.
All the best!
