A ketogenic drink improves brain energy and some measures of cognition in mild cognitive impairment">A ketogenic drink improves brain energy and some measures of cognition in mild cognitive impairment

Unlike for glucose, uptake of the brain’s main alternative fuel, ketones, remains normal in mild cognitive impairment (MCI). Ketogenic medium chain triglycerides (kMCTs) could improve cognition in MCI by providing the brain with more fuel. Read & Research Alzheimer’s More

Dementia: Paradigm shifting into high gear">Dementia: Paradigm shifting into high gear

Redressing the rising threat of dementia demands not only an increase, but a diversification of efforts. We need new approaches, trials, and partners. We cannot afford to continue to only round up the usual suspects, β amyloid, and tau and try to stop them with a single drug “silver bullet”. Read & Research Alzheimer’s More

New research shows that light and moderate exercise benefits the brain both immediately and in the long run, providing a person is active frequently. Read & Research Alzheimer’s More

Erratum to “Altered bile acid profile associates with cognitive impairment in Alzheimer’s disease—An emerging role for gut microbiome” [Alzheimer’s & Dementia 2019;15:76-92.]">Erratum to “Altered bile acid profile associates with cognitive impairment in Alzheimer’s disease—An emerging role for gut microbiome” [Alzheimer’s & Dementia 2019;15:76-92.]

In the article “Altered bile acid profile associates with cognitive impairment in Alzheimer’s disease—An emerging role for gut microbiome,” published in the January 2019 issue of Alzheimer’s & Dementia, the e-mail address listed for author Rima Kaddurah-Daouk is incorrect. The correct addresses are kaddu001@mc.duke.edu and rima.kaddurahdaouk@duke.edu. Read & Research Alzheimer’s More
