Until a few years ago, it was believed that children outgrow ADHD in adolescence. Hyperactivity often does diminish during the teen years, but it is now known that symptoms of ADHD can continue into adulthood.
In fact, up to 65 percent of children with ADHD will continue to exhibit symptoms in adulthood and in a major proportion it may still have a negative impact on their functioning in all aspects of life and society.
Males are far more likely to get ADHD, with the ratio of males to females with ADHD 3 to 1. However, ADHD tends to be under-diagnosed in girls as they more frequently present with the inattentive type, which is more difficult to identify than the hyperactive-impulsive type.
In certain conditions a higher incidence of ADHD is found, i.e. Tourette’s syndrome or foetal alcohol syndrome.
