A study of nearly 13,000 adults found that people consuming the most artificial sweeteners experienced a 62% faster decline in memory and thinking skills, equivalent to approximately 1.6 additional years of brain aging. Six popular sweeteners were linked to faster cognitive decline, raising concerns about the long-term brain health effects of common sugar substitutes, although causation was not established.

Sugar substitutes are often promoted as a healthier way to enjoy sweet foods and drinks without consuming as much sugar...

A new UCLA study has found a connection between how quickly the brain ages and the bacteria and chemical byproducts found in the gut, offering a clue to what drives brain aging long before symptoms appear.

Researchers have long used brain scans to estimate a person’s “brain age,” a measure that can differ from someone’s actual age in years. When a brain looks older than expected on a scan, prior research has linked it to poorer memory, thinking skills and mood. However, most of these studies involved older adults or people with existing brain diseases. Whether this gap between brain age and chronological age means anything in younger, generally healthy people has been unclear.

In a new study published in the journal eBioMedicine, UCLA Health rese...

People who sleep poorly are more likely than others to have brains that appear older than they actually are. This is according to a comprehensive brain imaging study from Karolinska Institutet, published in the journal eBioMedicine. The paper is titled “Poor sleep health is associated with older brain age: the role of systemic inflammation.”

Increased inflammation in the body may partly explain the association.

Poor sleep has been linked to dementia, but it is unclear whether unhealthy sleep habits contribute to the development of dementia or whether they are rather early symptoms of the disease.

In a new study, researchers at Karolinska Institutet have investigated the link between sleep characteristics and how old the brain appears in relat...

Restricting calories is known to improve health and increase lifespan, but much of how it does so remains a mystery, especially in regard to how it protects the brain. Buck Institute for Research on Aging scientists have uncovered a role for a gene called OXR1 that is necessary for the lifespan extension seen with dietary restriction and is essential for healthy brain aging.

“When people restrict the amount of food that they eat, they typically think it might affect their digestive tract or fat buildup, but not necessarily about how it affects the brain,” said Kenneth Wilson, Ph.D...
