clover, if left untreated as a child it can make teenage years damaging and life as an adult much harder.
the low self esteem is one thing but its the thought patterns that need to ve changed as an adult that can make things difficult.

many things kids with adhd do that aren't their fault as treated as the child being naughty or careless. but either help and medication can easily be sorted and corrected.

next year I will get my oldest son tested as I see familiar patterns and I will have no trouble medicating him should he need it.

in saying that, please research the meds to help your child find the best one. some make you very blah, some make you feel strange- locked in was a good description and some click and make things clear for you.
an adhd child will always have a lot of energy so teaching them relaxation and wind down exercises can make a big difference.
