Study suggests kids are diagnosed with ADHD because they are young for their class
Are kids being diagnosed with ADHD just for being young?
According to a new Canadian study, it might just be because they're younger than their peers.
In British Columbia, the age cutoff date for entering each grade is December 31st of whatever year — making those born in December the youngest in the class, and those born in January the eldest. Examining a cohort of more than 900,000 students, the researchers found a significant correlation between birth month and ADHD diagnosis. In fact, children born in December were 39% more likely to be diagnosed and 48% more likely to be treated with medication for ADHD than those born in January. The situation was even worse for young girls, where the December-born were 70% more likely to be diagnosed.
This research paints a picture of children who are immature due to age differences being treated as though they have a lifelong disorder.
"The relative age of children is influencing whether they are diagnosed and treated for ADHD," said lead author Richard Morrow in a statement. "Our study suggests younger, less mature children are inappropriately being labelled and treated. It is important not to expose children to potential harms from unnecessary diagnosis and use of medications."
