My girl was often thought to have ADHD. She's 10 now and the jury is still out, but basically, if she is properly stimulated and engaged, she's fine.
My son is the same. Also:
"probably ADHD" would set off alarm bells, especially if you see different behavior in every other setting.
...same again - his behaviour changes in different settings. Our pediatrician doubts the diagnosis, and even the psychologist said "take it with a grain of salt" saying that the assessment didn't reflect his true cognitive potential, just his current behaviour in a testing setting. He was seven. She recommended testing again in two years.
I contacted SENG and the person I spoke to said that often gifted kids have prefrontal cortex developmental delays which mimic ADHD (and which they'll grow out of) and they should never be assessed before the age of eight.
Cola this is a good book:
http://www.amazon.com/Misdiagnosis-Diagnoses-Gifted-Children-Adults/dp/0910707642My experience is that if giftedness doesn't present as straight A's and perfect behaviour, teachers miss it or disregard it. At least you have good test results - is the school not factoring those in?
It's tough. My son has the desk wiggles too. He'd even fall out of his chair. He'd be so distracted... more interested in how the wiring worked for the overhead projector than listening to the teacher. Any time he'd use the pencil sharpener he'd stay there because he wanted to take it apart and figure out how it works too.
He's calmer now, more able to comply even when he doesn't feel like it, but he's also 2 years older than your son. It gets better
I should add - I'm a SAHM and I enrich both my kids at home (accelerated math and reading). What do they call that... "after schooling" ?? I think it's hard to find the perfect scenario, but this seems to work for us.
