Attention-deficit hyperactivity disorder, also known as ADHD, is something that is found among younger children in a class as compared to their older classmates, researchers have stated. It has also been suggested that ADHD is not the problem but immaturity might be.
A study was conducted by researchers on Canadian children and there were over 900,000 children and they all were six to 12 years of age. This there have been two earlier studies also that were carried out in the US and this one dovetails with them.
It is worth mentioning that the US studies also stated what this study has said.
According to the study conducted by Dr. E. Jane Garland, a child and adolescent psychiatrist at the University of British Columbia in Vancouver and colleagues states that chances of getting an ADHD diagnosis were 30 per cent in younger children in a class as compared to classmates who were older and in girls these chances were about 70 per cent.
Garland said, "The younger children in a grade were significantly more likely to be diagnosed, labeled, and treated with medication for what in some of them must simply be immaturity."
