Electrophysiological changes in children with different subtypes of attention deficit hyperactivity disorder

Abstract EN

Attention Deficit Hyperactivity Disorder (ADHD) is the most common psychiatric disorder of childhood.

This study investigated the Electroencephalography (EEG) changes among different subtypes of attention deficit hyperactivity disorder children.

The study group (60 children) was divided into three subgroups according to the 3 subtypes of ADHD.

All children were between the ages of 5 and 14 years.

EEG was recorded during an eyes-closed resting condition.

The present study revealed that 47% of all ADHD groups showed electroencephalographic changes.

There were significant differences among ADHD subtypes regarding intensity of LT frontal alpha wave, which was significantly increased in combined ADHD group more than in inattention and hyperactive-impulsive ADHD groups, but there were no significant differences between ADHD subtypes regarding intensity of other EEG waves.
