Severe COVID-19 infection results in cognitive impairment similar to that sustained by natural aging between the ages of 50 to 70, and is equivalent to losing 10 IQ points.
Using whole-brain virtual models, researchers simulate the effects of non-invasive neurostimulation on the aging brain. The computational models shed light on the dynamics of brain changes as a result of aging.

A new artificial intelligence algorithm analyses MRI data to accurately predict the age of a brain.
Older adults who remain active have more of a class of proteins that enhance synapses to help maintain healthy cognitive function.
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.
People whose blood pressure is elevated but still falls within the normal range are at increased risk of accelerated brain aging, researchers report.
