New ADHD test analyzes brainwaves
Doctors have been given the green light by the Food and Drug Administration to start using a new tool to diagnose ADHD, one that utilizing electroencephalograms (EEG) to record electrical impulses produced by neurons in the brain. This new test takes between 15 and 20 minutes and calculates the ratio of two known brain wave frequencies, which can be higher in children and adolescents with ADHD, compared to their peers without the condition. It’s believed that this approach can more accurately determine than traditional methods if ADHD is the source of a behavioral problem.
NEBA Health, based in Augusta, Georgia, conducted a clinical trial involving 275 children and adolescents, aged 6 to 17. All of the participants underwent both conventional testing – which utilizes behavioral questionnaires and testing, IQ tests and physical examinations - and testing using the NEBA System. When the results of both tests were shown to an independent group of ADHD experts, the experts concluded that the EEG-based test provided a more accurate diagnosis.
Some experts, however, have questioned if anyone will use the machinery, arguing that it’s unnecessary, even if it is slightly more accurate.
