Skip to 0 minutes and 9 secondsCATHARINA HARTMAN: How common is ADHD actually? About 5% of all children are diagnosed with ADHD. That's about one or two people in every class. ADHD is more common in boys than girls. About three times as many boys than girls have ADHD. Most people with ADHD are diagnosed in primary school. From adolescence on, symptoms tend to get milder. And for some people, the symptoms completely disappear. In the end, about half of the people diagnosed with ADHD in childhood do much better later in life. But this is not so for the other half. They remain impaired throughout their life due to the symptoms of ADHD.
