I agree with smallworld, but I know for my difficult child and husband they both need a stimulant thrown into their mix but, and this is a big huge but, it had to be added only after they were stable on mood stabilizers and an ap. difficult child did horrible on stims alone, and I do hope to get him off it eventually.
I would try to go the route of no stimulant, it is certainly safer. AD are another big no.
Have they tried Lamictal yet? If not, it may be a good option. I wonder if they have not tried it due to the fact it takes a while to titrate up on it.
