Brain volume study reveals anti-aging potential of taking the stairs

A new study suggests that even a moderate uptake of physical activity, such as taking the stairs instead of the elevator, can counter volume loss in key brain regions

Although we generally understand exercise to be good fo us in all sorts of ways, scientists continue to make interesting inroads around the specifics of this relationship. The latest comes from a team in Germany which has found that even slight changes to regular physical activity, such as taking the stairs instead of the elevator, can counter the age-related loss of volume in brain regions linked to disease.

New evidence shows how viral infections could promote Alzheimer’s

The lab-based research found certain viral molecules could enhance the aggregation of toxic proteins linked with several neurodegenerative diseases

Building on a growing body of evidence linking viral infections with neurodegenerative disease, a new study published in Nature Communications has demonstrated how certain molecules on the surfaces of viruses can promote the aggregation of toxic proteins associated with diseases such as Alzheimer’s and Parkinson’s.

Switching off noisy neurons in mice restores memories lost to Alzheimer’s

A new mechanism by which Alzheimer's impairs memory recall has been discovered

Researchers in Germany have discovered a new mechanism by which Alzheimer’s disease impairs memory recall – and, importantly, found a way to reverse it in mice. Neurons encoded with existing memories are being drowned out by noise from neurons encoding new experiences, and silencing these allowed the mice to regain lost memories.
