It’s not that simple. And 10 year old boys have a range of behaviors. There is a very big majority in the bell curve of 10 year old behaviors that would never be thought to need medical help. Parents do not wish to drug their children. Schools are not allowed to force meds on kids. Doctors often want to, but that is their deal.
No one ritalinizes normal 10 year old boys. Kids have a lot more behavioral issues today, sometimes from home life but mostly from malfunctioning brains - a change of diet for the child would possibly cure many. Drugs are as a last resort.
Come to PS 123 in Brooklyn and IS 163 in Brooklyn. You would be shocked what school psychologists and social workers convince parents to do.
