Ginkgo biloba has been reputed as an aid to brain health and neurological conditions for centuries by traditional doctors. Ginkgo’s usefulness for children with attention deficit/hyperactivity disorder has now been confirmed by a clinical study from Germany. This is supported by previous research showing Ginkgo’s effects on cognition among the elderly.
The ADHD research comes from the University of Tübingen’s Center for Medicine, Society and Prevention.
Researchers tested a Ginkgo biloba extract called EGb761 on 20 children diagnosed with ADHD in an open clinical protocol. The children were given the Ginkgo extract for three to five weeks at a dosage of up to 240 milligrams. This maximum dosage was given to those children who did not have immediate effective responses to a lower dose over the initial period of three weeks.
The researchers utilized clinical assessments to rate the improvement in symptoms along with the Continuous Performance Test (Cue-CNV in the CPT) that tested the brain’s electrical activity among the children. The researchers also assessed the children with quality of life testing and the Side Effect Rating Scale.
What is CNV testing?
Contingent negative variation (CNV) testing utilizes magnetoencephalography (MEG) to measure the amplitudes of brain waves that correspond to attention and stimuli. These waves are thought to originate from the premotor cortex.
The researchers found that the Ginkgo extract improved ADHD symptoms among the children. This improvement corresponded with improved CNV results.
