Researchers from the Mayo Clinic have identified a new target in the battle against dementia and age-related cognitive decline – zombie cells. More formally known as senescent cells, these are cells that have stopped dividing but don’t die, and tend to accumulate with age. The new research reveals that many pathological signs of neurodegenerative disease can be eliminated by removing these cells from the brain. read more

Hope for Alzheimer’s Patients

from Sky News:

Patients have been implanted with a tiny “brain pacemaker” in an attempt to slow the progress of Alzheimer’s disease.

Three patients were fitted with the device, which fires electric pulses into surrounding cells, as part of the ground-breaking trial.

 Doctors report that it reduced the speed at which their brain function declined. In two patients, the effects were significant. read more

Our Brains Also Sag with Age

The numerous folds which cover our brains change over time, becoming slacker as we age, according to a study.

What’s more, this slacking was seen to be more pronounced in those with Alzheimer’s disease.

Researchers believe that learning more about how the mechanisms which control how folding changes with age could potentially be used to help diagnose brain diseases and spot dementia.
