Veronica, here you could file a neglect petition with DCF if a child was not being given his/her medication.
Does the mother have a reason for not medicating him? Often times, parents, especially those with cultural, educational, or other handicaps really don't understand anything about ADHD. Of course she is probably mourning the loss of her "ideal" child, but if she understands that ADHD is an illness and not a deficit, she might be able to see how medication can help him achieve his potential.
I have seen this issue from the point of view of a parent, teacher, and therapist. It always surprised me when parents refused to consider medication. It doesn't mean you are a failure or your kid is a loser. And, you still need to use all of the other organizational strategies to help the child. Both of my kids were similar to this kid. Brilliant, but with the short term memory of a gnat and one was extremely disorganized, the other impulsive. One took medication for 7 years, and then through sheer will and determination made it through HS as an honors student with no meds. The other one tried meds in HS and they made him agitated, so he stopped. He would have achieved much more at that point in his life, if he hadn't had the side effects; now there are a lot more choices.
I don't think anyone, parent or not, can really know how it feels to have ADHD. It's really limiting, causes a lot of marital distress and firings from work. About 30% of the incarcerated population in the US has it. People think it's over diagnosed, but it's more that years ago, not everyone made it to high school, and there were more options/careers for people who didn't succeed. academically. Life was different.
Don't be so quick to judge. Of course a child's treatment is always in the hands of the parent, but sometimes, a parent really does not have the right information to make the right decision.
