Tests of brainwaves using EEG may be helpful in distinguishing subtypes of ADHD, helping to diagnose whether a teen’s symptoms are mainly inattention or mainly hyperactivity and impulsiveness.
The two subtypes of attention-deficit/hyperactivity disorder (ADHD) are known as “inattentive” or “combined” and as well as telling these apart, the brain tests also help to rule out normal adolescents.
The researchers, publishing their study in the journal Biological Psychiatry, say the electroencephalogram (EEG) readings illustrate “that these groups display distinct physiological profiles.”
This means there may be an objective biological test for differences that are subjectively observed in the clinic.
“This study shows that there are changes in brainwaves related to visual processing and motor planning that can be used to distinguish ADHD subtypes,” says Ali Mazaheri, assistant professor University of Amsterdam, the Netherlands, and guest researcher at the Center for Mind and Brain of the University of California, Davis.
