People with older-looking brains were born with lower birth weight and genes for smaller brains compared to those with normal aging brains, a new study reports. As both factors present early in life, researchers say "brain age" is likely related to early life influences and not so much on events that occur later in life.
In both aging human and mouse experiments, researchers identified a link between the MEF2 gene and cognitive resilience. Findings suggest enhancing MEF2 activity could protect the brain against age-related dementia.
A diet high in processed foods leads to neuroinflammation and memory decline in older rats, a new study reports. Supplementing a processed food diet with DHA, an omega 3 fatty acid, helped mitigate memory problems and reduce inflammation.
The Tsimane, an indigenous people from the Bolivian Amazon, have less brain atrophy than American aging adults, a new study reports. Additionally, the decrease in their brain volume associated with aging is 70% less than seen in older American adults.
