Memory

Adequate sleep is crucial for overall health. Insufficient sleep often leads to heightened cognitive deficits. A recent study reveals that older adults with insomnia face a higher risk of memory decline and long-term cognitive impairments, which can lead to dementia. The study utilized a large dataset and primarily focused on sleep disorders.

As a person ages, the brain gradually shrinks, losing about 5% of its volume per decade after age 40, impacting its functionality. In a pioneering study, neuroscientists investigated how regular aerobic exercise affects the hippocampus, the brain region responsible for memory. 

A new study at the University of Exeter has discovered another good reason to live a healthy lifestyle!  The research found that in people with a high genetic risk for developing dementia the risk was 32 percent lower if they followed a healthy lifestyle.
