Detecting kids with ADHD can be tricky sometimes, simply because of their age.
Meanwhile, a new study shows that it doesn't always matter whether the diagnosed kids are young or a bit older.
Let's find out more about how it works.
How it was detected
A new study looked at children with ADHD, and it found something interesting.
Some people thought that the youngest kids in a class might be diagnosed with ADHD just because they are less mature than the older kids.
But this study showed that these younger children with ADHD are just as likely to keep the diagnosis as the older kids in their class.
ADHD is a condition that makes it hard for people to focus and control their actions.
It's often seen in kids, but it can affect adults too.
The study looked at a huge group of over 6,500 people from around the world, and they followed them from ages 4 to 33.
Why it might be important
The study doesn't say if the ADHD diagnosis is right or if it's just because once a child is called ADHD, people treat them that way.
More research is needed to figure that out.
But it's interesting to see that being the youngest in the class doesn't necessarily mean you'll outgrow ADHD.
