STATISTICS

ADHD is actually more common than you might realise.

It was first described about 100 years ago but is no more prevalent now, just better recognised. 


The incidence of ADHD is approximately the same across all countries and races. And although up to three times as many boys are diagnosed with ADHD as girls, it's now suspected the ratio is more like 1:1.​

  • ADHD affects 2%-5% of all children. However, approximately one-third of children outgrow it by the time they're a teenager.
  • Of the teenagers who continue to have ADHD, approximately one-third will grow out of it by adulthood and one-third of adults will eventually mature out of the symptoms and no longer meet diagnostic criteria.
  • This isn't to say that those who grow out of it won't still experience behaviours consistent with ADHD but on reassessment, they would no longer experience them enough to warrant a diagnosis.
​
A lot of parents who have children assessed and diagnosed with ADHD begin to wonder if they are part of the 25% of parents with a child of ADHD who also has it.
