OR he could be 6. Please be very careful of "labels". Yes, some are necessary, but it is my experience (over 25 years working with labeled kids) if you go looking for a label, you will find one. If you go looking for a solution, you will find that too.
Please keep in mind education not medication.
Does he have the same reactions at home?
You mentioned triggers, a month is not necessarily enough time to determine triggers or not. Keep a log of all behaviour AND FOOD!
How does he come out of the situation?
Does he know what happened when he gets like that? Is he still in control?
What is the pattern? There is ALWAYS a pattern.
R., there is so much more to it than a teacher saying he is having problems. PLEASE do your due diligence. Take him to a doctor, sure, but know that they only know medicine. As a Family Success Coach, I have seen more than my share of families getting themselves into medical situations (meaning prescribing of drugs for their kids) that could have been easily handled by change of diet and supplementation to their diet. Ask a LOT of questions. ASK what kind of natural alternatives they suggest if they begin talking about drugs.
But don't get ahead of yourself. Find out what is going on for him, with him. Ask him, talk to him, visit his classroom, do whatever you have to do to find out if this is something that needs medical attention or can it be changed with good old fashioned parenting.
