About 5-8% of all people over the age of 65 have some form of dementia, and this number doubles every five years above that age. Dementia is the loss of mental ability, severe enough to interfere with people's every life and Alzheimer's disease is the most common type of dementia in aging people.

Capsules containing 60 mg of a standardised extract of Ginkgo biloba (GK501) and 100 mg of a standardised extract of Panax ginseng (G115) showed significantly to improve an Index of Memory Quality(593), including learning and memory  but not working and long-term memory(596). Its extract, in the logical memory test and nonsense picture recognition  exhibits improvement of 58.62% logical memory in compared to baseline(594). Comercial extract Ginkgo biloba EGb 761 enhanced certain neuropsychological/memory processes of cognitively in older adults, 60 years of age and over(595).

b. Cognitive performance

On acute cognitive effects, Ginkgo biloba extract (GBE) with soy-derived phospholipids, improved secondary memory performance and significantly increased speed of memory task performance in comparision to post-dose testing sessions(599).
