Attention deficit hyperactivity disorder (ADHD) is a developmental and behavioral disorder that affects 3% to 5% of all school-age children.
Although the condition usually manifests in childhood, it can persist into adulthood, causing difficulties at home, at school and at work if not recognized and
treated.
ADHD
Symptoms:
The symptoms of ADHD include inattention and/or hyperactivity-impulsivity that are inappropriate for age.
There are three different types of ADHD. Combined ADHD (the most common type) includes all of the symptoms. Inattentive ADHD is marked by impaired attention and concentration and hyperactive-impulsive type is marked by hyperactivity without inattentiveness.
To help recognize ADHD, understand that some symptoms that cause impairment must be present before age seven years and some impairment from the symptoms must be present in more than one setting (like home and school or home and work).
In fact, experts now estimate that ADHD affects about 60% of adults who had ADHD in
childhood.
