You might try getting him tested for nutritional deficiencies.

Years ago, I read about a vitamin therapy protocol that was helpful for kids with autism and I put my son on the parts of it I could find, which was some B vitamins and magnesium. After a few months, his handwriting improved and so did his social skills.

He's in his thirties and a lot more functional than I ever thought he would be. To this day, when he starts making me too crazy the solution is "he needs B vitamins." (I typically try to get some steak into him at that point so he stops being weird and difficult.)

Thanks. We have tested him for nutritional deficiencies and vitamin supplementation is making a difference. Doing it for a few years now.
