Memory and Intelligence

For centuries man is trying to explore ways to enhance the memory performance. Several researches and studies are there.

Scientists (Vasudevan, Mani et al.) found that Thespesia populnea bark appears to be a promising candidate for improving memory, and it would be worthwhile to explore the potential of this plant in the management of Alzheimer patients. This bark is found in Indian region. Studies (P. T. Staff) indicate that ginkgo can help improve memory, concentration and mood. Ginkgo is recommended in a dose of 40 mg to 80 mg three times per day of an extract standardized to 24% flavonoid glycosides and 65% terpenoids. Expect to take the herb for at least eight weeks before seeing an improvement in memory.

(A.T. Frais) Omega-3 fish oil has been shown to improve memory. (Health News) Omega-3 might ease depression, enhance mind & memory. There's a growing body of evidence that DHA benefits gray matter, but it's not a cure-all, say researchers.

(P. T. Staff) Memory experts are now focusing on phosphatidyl-serine (PS), a naturally produced, fat-soluble nutrient. Found throughout our bodies, PS works particularly hard in the brain to improve brain cell communication and regulate serotonin and dopamine--both mood-related chemicals. Numerous studies have shown that people who take PS remember more names, faces, phone numbers and written information. And research conducted by Thomas Crook, Ph.D., founder of the Memory Assessment Clinic in Bethesda, Maryland, found that subjects who took 300 mg of PS for 90 days showed remarkable improvement in their memory. PS, according to Kidd, "can turn back the clock 12 to 15 years."
