Cannabis Reverses Aging Processes in The Brain Say Researchers
Like any other organ, our brain ages. As a result, cognitive ability also decreases with increasing age. This can be noticed, for instance, in that it becomes more difficult to learn new things or devote attention to several things at the same time. This process is normal, but can also promote dementia. Researchers have long been looking for ways to slow down or even reverse this process.
Afterwards, they tested learning capacity and memory performance in the animals – including, for instance, orientation skills and the recognition of other mice. Mice who were only given a placebo displayed natural age-dependent learning and memory losses. In contrast, the cognitive functions of the animals treated with cannabis were just as good as the two-month-old control animals. “The treatment completely reversed the loss of performance in the old animals,” reported Prof. Andreas Zimmer from the Institute of Molecular Psychiatry at the University of Bonn and member of the Cluster of Excellence ImmunoSensation.
Years of meticulous research
This treatment success is the result of years of meticulous research. First of all, the scientists discovered that the brain ages much faster when mice do not possess any functional receptors for THC. These cannabinoid 1 (CB1) receptors are proteins to which the substances dock and thus trigger a signal chain. CB1 is also the reason for the intoxicating effect of THC in cannabis products, such as hashish or marihuana, which accumulate at the receptor. THC imitates the effect of cannabinoids produced naturally in the body, which fulfil important functions in the brain. “With increasing age, the quantity of the cannabinoids naturally formed in the brain reduces,” says Prof. Zimmer. “When the activity of the
cannabinoid system declines, we find rapid ageing in the brain.”

To discover precisely what effect the THC treatment has in old mice, the researchers examined the brain tissue and gene activity of the treated mice. The findings were surprising: the molecular signature no longer corresponded to that of old animals, but was instead very similar to that of young animals. The number of links between the nerve cells in the brain also increased again, which is an important prerequisite for learning ability. “It looked as though the THC treatment turned back the molecular clock,” says Zimmer.
Next step: clinical trial on humans
A low dose of the administered THC was chosen so that there was no intoxicating effect in the mice. Cannabis products are already permitted as medications, for instance as pain relief. As a next step, the researchers want to conduct a clinical trial to investigate whether THC also reverses ageing processes in the brain in humans and can increase cognitive ability.
The North Rhine-Westphalia science minister Svenja Schulze appeared thrilled by the study: “The promotion of knowledge-led research is indispensable, as it is the breeding ground for all matters relating to application. Although there is a long path from mice to humans, I feel extremely positive about the prospect that THC could be used to treat dementia, for instance.”

you cant reverse the aging process dumbass. You can potentially slow it down, but not reverse it
I wouldn’t shout that to loud. https://motherboard.vice.com/en_us/article/engineering-the-end-of-aging?trk_source=homepage-lede
100 cones a day helps keep the doctor away no wonder i feel and look so young.
From your avatar you look sixteen and from your nick I feel you got that right.
I was always pro-cannabis,eating it and using its oil for medical purposes not smoking it,but now that the university of Jerusalem has come out in favor,I`ll have to rethink my position.
I hereby volunteer to be a guinea pig on this one send me all your weed and let the research begin!
All these ”miraculous” things revealed from hemp plants resin actually were revealed in the WHO long term study which was not published because of political reasons. Report briefly emerged in EU parliament, but was not published, because politicians would have been forced to take responsibility for criminalizing not only important, but also worlds oldest medical plant. Over 90% of cancers react well to cannabis treatments, although there is evidence that different cancers require different strains. Next time you you see a politician speaking, just think of dementia, MS-disease and childrens cancer ward…
