Adults and children as young as 4 utilize the same neural network, the multiple demand network, to help solve difficult cognitive problems. The findings demonstrate this important network for problem-solving and attention develops early in life.
Ultra-processed foods have been linked to accelerated cognitive decline associated with aging and an increased risk of developing dementia. Researchers say it may be possible to mitigate some negative dietary effects on cognition by adopting a healthier diet, such as the keto or Mediterranean diet.
A genetic predisposition to oral health problems increased the risk of white matter hyperintensities and was associated with a 43% increase in microstructural damage in the brain.

Adopting a healthy lifestyle, in particular, a healthy diet was associated with a slower than average decline in memory over ten years in older adults, even those with the APOE4 Alzheimer's associated genetic variant.
