High on memory

Author: admin

Here ’s ano ther sho t in the arm for advocates of legalising cannabis. A recent study by scientists at the University of Bonn and the Hebrew University of Jerusalem contend that cannabis can combat age-related decline in memory. For their study, published in journal Nature Medicine, they administered THC (the active ingredient in cannabis) to a group of mice aged two, twelve and 18 months over a period of four weeks and tested their learning and memory skills. As website tells us, the older mice who received THC displayed cognitive functions equal to the youngest mice. “The treatment completely reversed the loss of performance in the old animals,” says lead author Andreas Zimmer. “With increasing age, the quantity of the cannabinoids naturally formed in the brain reduces. When the activity of the cannabinoid system declines, we find rapid ageing in the brain. It looked as though the THC treatment turned back the molecular clock.”
