How long does it last?
About 80% of children with ADHD have symptoms that persist through high school. Of those, 50% have symptoms into adulthood. 

If untreated, children with ADHD of the hyperactive-impulsive type are at high risk for school failure. Their lack of social skills can lead to difficulty making and maintaining friendships and as a result they can experience sadness and feelings of rejection. Their impulsivity and lack of judgment may bring them into conflict with the law.

Among children and adolescents with ADHD, there are high rates of co-existing psychiatric disorders such as conduct disorder, anxiety disorder, or depressive disorders, and oppositional defiant disorder. They also have higher rates of alcohol, nicotine, and other drug abuse.[1]
