What is the exact differance between the ADHD chiled, and a impressively moving typical chiled?
The physician diagnosing is the main difference contained by many cases. ADHD is fundamentally difficult to accurately diagnose. It has be suggested that we have begin to over diagnose this disorder in leui of disciplining and adjectives our children. The true ADHD child will have difficulty focussing on simple tasks for even short period of time.
An ADHD child hs problems with focus on one entry at a time. Attention span is very short.
my son have ADHD - and his attention span was not physical long -especially in academy - he struggled all the means of access thru - or if it something doesnt interest him - but if it is something he likes - video games, legos, etc ... they can sit nearby for hours on end.
In my inference - one of the worst traits of ADHD is the impulsiveness - Where as most will meditate about what they do in the past they do it. but a child with ADHD will do something first - next think give or take a few what they did after the fact. This is why most of these kids bring back into trouble - or fall into the wrong crowds.
My son - who is 20 in a minute - was not a desperate kid - he actually have a heart of gold - but he did put together a lot of wrong decision that he came to regret soon after. Nothing serious - Thank honour - but i worry in the order of him more than i do my other 2.
The worst part is for the kid - they only don't realize or understand why they do partly the stuff they do and people and teacher just overhaul them off as "bleak kids" when that is really no the valise. Even as a mother - it took me a while to understand it myself.
