Tag: Cognitive Decline

Researchers publishing in Aging have found a correlation between cognitive decline and measurements of epigenetic aging. Familiar epigenetic clocks Epigenetic Clocks - What are they?An epigenetic clock is a biochemical test that uses DNA methylation levels and accumulation of methyl groups on DNA to determine biological age. There are many different kinds of clocks, and...

Researchers publishing in Nutrients have shown that adding a strain of lactic acid bacteria to the gut flora of older, memory-impaired people partially alleviates their memory problems. A specific anti-inflammatory bacterium The researchers begin their paper by noting that mild cognitive impairment (MCI) is associated with memory loss and is frequent precursor of Alzheimer's disease...

In a large randomized, placebo-controlled study, scientists hoped that cocoa extract would improve cognitive function in elderly patients, but instead it was a multivitamin supplement that shined [1]. A two-in-one study Multivitamins are among the most popular dietary supplements, but their effectiveness is often questioned. While some studies did fail to find any significant benefits...

A new study published in Nature Neuroscience has shown that neuromodulation of low-frequency neuronal activity in the parietal cortex improved working memory, while high-frequency modulation in the prefrontal cortex improved long-term memory in older adults [1]. As people age, their cognitive abilities get worse. This includes memory decline, which might dramatically impact quality of life....

Published in GeroScience, a groundbreaking study from the renowned Conboy lab has confirmed that plasma dilution leads to systemic rejuvenation against multiple proteomic aspects of aging in human beings. Systemic molecular excess This paper takes the view that much of aging is driven by systemic molecular excess. Signaling molecules, antibodies, and toxins, which gradually accumulate...

A new study published in Neurobiology of Aging has shown that neither caloric restriction nor intermittent fasting improve late-life cognition in genetically diverse mice, but the effect depends on genetic composition [1]. Eat less, think better? Dietary interventions are known to have potential to extend lifespan and delay age-associated diseases, at least in animal models....
