Teens often continue to have the symptoms of
attention deficit hyperactivity disorder (ADHD) that
began in childhood, although they are expressed differently.
Inattention
This symptom is the most difficult to identify in childhood. The
primarily inattentive ADHD subtype may not be recognized at all until a child
grows into a teen. Although symptoms of inattentiveness begin during childhood,
a child may be able to function fairly normally. In addition, family members
and other caregivers may be able to help the child to compensate, without
realizing the problem might be ADHD. As adolescence approaches, inattentiveness
may become pronounced with the new demands from increasing academic workloads
and other responsibilities.1 Problems usually develop
that prompt an evaluation for ADHD during major transition points, such as when
starting middle school, high school, or even college.1
Impulsivity
Because of their impulsivity, teens with ADHD are more likely to
engage in risky behaviors, such as reckless driving, having unprotected sex, or
using alcohol or drugs.
Hyperactivity
Obvious symptoms of hyperactivity may decrease during the teen
years, but they may be replaced by fidgeting or feelings of restlessness.
Other conditions
Children with ADHD may have
oppositional defiant disorder (ODD). If a child has
ODD, it may lead to
conduct disorder during the teen years, especially if
left untreated.
Children with ADHD may develop low self-esteem, which is most
likely related to the child's difficulty with relationships and poor
performance in school. Because of their ADHD symptoms and risk for low
self-esteem, teens may become depressed or develop other emotional
illnesses.
