In a groundbreaking study by Tufts University, researchers found a significant correlation between vitamin D levels in the brain and cognitive performance. This research, which examined brain tissue from 290 participants, discovered that higher levels of this vitamin were associated with better cognitive function, stronger memory, and slower cognitive decline. These elevated levels corresponded with...
By Eric W. Dolan July 25, 2023 in Cognitive Science, Neuroimaging (Photo credit: psdesign1) A drug called prucalopride appears to enhance functional connectivity between major cognitive networks in the brain, according to new research published in Biological Psychiatry: Cognitive Neuroscience and Neuroimaging. The new findings provide a possible explanation for why previous studies have shown that drugs that...

by Jim Dryden, Washington University School of Medicine Older adults work with exercise trainers as part of a study to see whether exercise, mindfulness training, or both might improve cognitive performance in seniors. A new study did not show such improvements, though the researchers are continuing to explore whether there may be some cognitive effects...

WILEY Previous studies have looked for links between glaucoma—a neurodegenerative disorder that’s the leading cause of irreversible blindness—and cognitive function, but they’ve generated mixed results. Findings from a large study recently published in the Journal of the American Geriatrics Society suggest that any association may be small or absent. In the study that included 7,073 US adults...
Sleep plays an important role in enabling cognitive function and maintaining good psychological health. It also helps keep the brain healthy by removing waste products. As we get older, we often see alterations in our sleep patterns, including difficulty falling asleep and staying asleep and decreased quantity and quality of sleep. It is thought that these...
