Scientists Reverse Memory Loss Caused by Aging in Mice

https://interestingengineering.com/scientists-reverse-memory-loss-caused-by-aging-in-mice

Scientists at the University of Cambridge have found the cause of aging-related memory loss in mice. During the course of their research, they discovered that memory loss could even be reversed in old mice in laboratory experiments.

Scientists have been looking for the causes of age-induced memory loss. They found one in the scaffolding that holds the brain's neurons in place. Called perineuronal nets (PNNs), these cartilage-like structures surround the neurons in our brain. Intriguingly, these nets appear at the age of five in humans after a period of neuroplasticity during which the brain learns, adapts, and makes memories.

The role of the PNNs is to reduce the plasticity in the brain, making it less capable of creating new memories while increasing the efficiency of the brain in performing regular tasks.

This is why learning becomes difficult as we age — PNNs are working to make the brain more and more efficient. This is done by a PNN constituent called chondroitin 4-sulfate.

Thanks! I'd think so too. That we're in a whole new era Hortensis Jul 2021 #5
Good news for those who employ competent older mice. Sneederbunk Jul 2021 #3

... An orally taken drug that has been licensed for human uses for other conditions can perform this task. Researchers have used it in mice studies before and now believe it could also reverse aging-related memory loss. The team is currently working to see if the treatment can work for Alzheimer's disease as well.


I'm not sure what it takes to get an existing drug approved for additional uses, but I should think it's easier than getting a new drug approved.

of great medical advances is exciting and inspiring, but even more when realizing new futures of relative wellbeing could be opening up for aged people.

Did that mouse have two pieces of cheese or three?
Truth is I can't remember myself.
