Abstract

Neuroplasticity, the ability of synapses to undergo structural adaptations in response to functional demand or dysfunctions is increasingly impaired in aging and Alzheimer's disease. EGb761® has been shown in several preclinical reports to increase nearly all aspects of impaired neuroplasticity (long-term potentiation, spine density, neuritogenesis, neurogenesis). While all three fractions of constituents (ginkgolides, flavonoids, bilobalide) seem to be active, the flavonoids and specifically the aglycone isorhamnetin seem to be most relevant.
