Researchers Restore Youthful Memory In Aging Mice
An anonymous reader writes "German neuroscientists made a breakthrough in 'age-related cognitive decline', a common condition that often begins in one's late 40s (especially declarative memory — the ability to recall facts and experiences). Their new study identifies a genetic 'switch' for the cluster of learning and memory genes that cause memory impairment in aging mice. By injecting an enzyme, the team 'flipped' the switch to its on position for older mice, giving them the memory and learning performance they'd enjoyed when they were young. Now the team ultimately hopes to recover seemingly lost long-term memory in human patients." The video, which explains the gene flipping mechanism, is worth a watch (2:18).
That's my age. I do notice tt takes just a wee bit more effort to cram more stuff in my head than it used to. Other than that, I still enjoy my ability to recall ridicules bits of obscure minutia that when viewed in total aren't enough to get me a good job, but are just enough to be annoying.
Seriously, though. My ability to commit stuff to memory and recall it *IS* one of my marketable skills. And anything that can help prolong the decline is welcome news.
It's not clear to me a treatment for normal cognitive decline would necessarily be effective for Alzheimer's.
Nov 21 - I did a dumb thing today I forgot I wasnt in Miss Kinnians class at the adult center any more like I use to be. I went in and sat down in my old seat in the back of the room and she lookd at me funny and she said Charlie where have you been. So I said hello Miss Kinnian Im redy for my lessen today only I lossed the book we was using.
