Brain discovery could block aging’s terrible toll on the mind
Faulty brain plumbing to blame in Alzheimer’s, age-related memory loss — and can be fixed. Faulty brain plumbing to blame in Alzheimer’s, age-related memory loss — and can be fixed. Aging vessels connecting the brain and the immune system play critical roles in both Alzheimer’s disease and the decline in cognitive ability that comes with time, new research reveals. By improving the function of the lymphatic vessels, scientists have dramatically enhanced aged mice’s ability to learn and improved their memories. The work may provide doctors an entirely new path to treat or prevent Alzheimer’s disease, age-related memory loss and other diseases.

Feeling young could mean your brain is aging more slowly
While some people are young at heart, others feel older than their age — and a recent study finds that this ‘subjective age’ may reflect brain aging. Researchers found that elderly people who feel younger than their age had a younger estimated brain age, compared with those who felt their age, or older than their age. The study is the first to find a link between brain aging and subjective age.
Treating Alzheimer’s with aspirin
A low-dose aspirin regimen may represent a new avenue for reducing Alzheimer’s disease pathology, according to new research in a mouse model. The study identifies a new role for one of the most widely used medications in the world.
Wearable device can predict older adults’ risk of falling
Every year, more than one in three individuals aged 65 and older will experience a fall. Treatment and awareness of falling usually happens after a fall has already occurred. Researchers wanted to see if they could predict an individual’s risk of falling so that preventative measures could be taken to reduce this risk.
