Greater BDNF expression in brain tied to up to 50% slower decline in memory in older people (for those in top decile of expression)
“Autopsies were conducted on their brains after death, and the amount of protein from BDNF gene expression in the brain was then measured. [...] > The rate of cognitive decline was about 50 percent slower for those in the highest 10 percent of protein from BDNF gene expression compared to the lowest 10 percent.”
