Brain wave test gets tick for ADHD

Regulators have approved the first "brain wave" test to help diagnose ADHD in children and teenagers.

The US Food and Drug Administration said on Monday it had cleared the NEBA (Neuropsychiatric EEG-based Assessment Aid) System for use in 6-17-year-olds.

The test, which takes about 15-20 minutes, uses EEG to calculate the ratio of theta to beta waves. This ratio has been shown to be higher in children with ADHD than those without.

Testing should form part of a wider battery
