News sources (Newsweek and others) are reporting today that "Scientists [have] discovered low doses of its main psychoactive ingredient—cannabinoid THC—can reverse the age-related decline in cognitive abilities, a finding that could lead to scientists figuring out a way of slowing brain aging in humans."
The reference is to a "... a study published in Nature Medicine on Monday, researchers led by Andreas Zimmer." The study results can be found here.
In the study, scientists "... created a task where mice had to locate a specific object. Older mice treated with THC performed to the same standard as young mice that had not been given the drug. A third test relating to partner recognition also showed THC led to improved memory in mature and older mice.
[Why mice? Thank you for asking...]
“Together, these results reveal a profound, long-lasting improvement of cognitive performance resulting from a low dose of THC treatment in mature and old animals,” the scientists write.
With 10,000 American turning 65 every single day, such studies on the effect of cannabis on aging could have profound impacts. Stay tuned.
