10 Key Indicators of ADHD in Children and Adults

Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder usually diagnosed in childhood, though it may persist into adulthood. According to the American Psychiatric Association, about five percent of children have ADHD. It can be difficult to distinguish between normal developmental behavior and ADHD in young children. That said, most parents find that by the time a child with ADHD reaches age seven, they start exhibiting symptoms that cannot be ignored.

1. Daydreaming

One of the hallmark symptoms of the inattentive subtype of ADHD is excessive daydreaming. While some daydreaming in the classroom is expected, children with ADHD may be unaware that their mind is drifting and may have a hard time staying in the moment. Unfortunately, daydreaming can interfere with learning. Parents and teachers might question whether the child can hear them talking, as the child typically does not respond to questions.
