Protective Potential of Ginkgo biloba against an ADHD-like Condition.

BACKGROUND
Attention deficit hyperactivity disorder (ADHD) is a psychiatric disorder commonly found in children, which is recognized by hyperactivity and aggressive behavior. It is known that the pathophysiology of ADHD is associated with neurobiological dysfunction. Although psychostimulants are recognized as the therapeutic drugs of choice for ADHD patients, the side effects might be of great concern. Ginkgo biloba is a promising herbal complementary supplement that may modulate the neuronal system in an ADHD-like condition. The beneficial effect of Ginkgo biloba on ADHD-like symptoms may be related to the modulation of the system by novel molecular mechanisms. Ginkgo biloba is known to modulate dopamine, serotonin, and norepinephrine signaling. Flavonoid glycosides and terpene trilactones are the two major phytochemical components present in the Ginkgo biloba preparations, which can exhibit antioxidant and neuroprotective activities. The pharmacological mechanisms of the phytochemical components may also contribute to the neuroprotective activity of Ginkgo biloba.


CONCLUSION
In this review, we have summarized recent findings on the potential of various Ginkgo biloba preparations to treat ADHD-like symptoms. In addition, we have discussed the pharmacological mechanisms mediated by Ginkgo biloba against an ADHD-like condition.
