The ADHD Test

What Is ADHD

The Attention Deficit Hyperactivity Disorder (ADHD) is one of the most common neurodevelopmental disorders in children.Although the diagnosis is usually made in childhood, symptoms may persist as the child gets older and reaches adulthood.The core symptoms of ADHD are difficulty paying attention, difficulty controlling impulses, and being very active.

According to the U.S. CDC (October 2016), the prevalence of ADHD is about 11% in children 4-17 years of age and 5% of all children. ADHD is about more common among boys (13.2%) than in girls (5.6%). The average age of ADHD diagnosis was 7 years of age, but children with more severe ADHD were diagnosed earlier.
