2. Defining ADHD
Healthline says that ADHD is a common neurodevelopmental disorder, often affecting children. There are different types of ADHD, but the most common version is a combination of “inattentive and hyperactive-impulsive symptoms,” it says.
The other types are predominantly hyperactive-impulsive, and predominantly inattentive, it adds. The average age of diagnosis for ADHD is 7-years, and it affects boys more often than girls, says the source.
