An interesting and very well-documented article in the Los Angeles Times reviews studies looking at Vitamin B and its role in improving memory.
The vitamins — including folic acid and vitamins B6 and B12 — are often touted as a way to improve memory and stave off cognitive decline. The claims are based on the finding that levels of the vitamin are low in people with various forms of cognitive impairment, including dementia and Alzheimer’s disease. But experts say it’s still unclear whether taking high doses of the vitamins will keep such conditions at bay.
[…] Haan says the existing body of studies may be inconclusive because the causes of cognitive decline — which are incompletely understood — are probably too complex to be halted with a single vitamin supplement.
Comments: To date, no supplement has been shown to effectively slow down cognitive decline and postpone Alzheimer’s disease symptoms. It seems that there is no magic pill to brain health and no single solution. Our best bet so far is a brain-healthy lifestyle including at least physical exercise, balanced diet, mental stimulation and brain training, stress management, and social engagement.
