Marijuana can surprisingly improve age-related memory loss

Washington, Nov 20 : A daily puff of a marijuana can help reduce memory loss in old age and fight Alzheimer's Disease, a shocking new study has revealed.

According to Ohio State University scientists, specific elements of marijuana can be good for the aging brain by reducing inflammation there and possibly even stimulating the formation of new brain cells.

The research suggests that the development of a legal drug that contains certain properties similar to those in marijuana might help prevent or delay the onset of Alzheimer's disease. Though the exact cause of Alzheimer's remains unknown, chronic inflammation in the brain is believed to contribute to memory impairment.

"It's not that everything immoral is good for the brain. It's just that there are some substances that millions of people for thousands of years have used in billions of doses, and we're noticing there's a little signal above all the noise," said Gary Wenk, professor of psychology at Ohio State and principal investigator on the research.

Any new drug's properties would resemble those of tetrahydrocannabinol, or THC, the main psychoactive substance in the cannabis plant, but would not share its high-producing effects.

"Could people smoke marijuana to prevent Alzheimer's disease if the disease is in their family? said Wenk.

"We're not saying that, but it might actually work. What we are saying is it appears that a safe, legal substance that mimics those important properties of marijuana can work on receptors in the brain to prevent memory impairments in ageing. So that's really hopeful."

The research, which was presented to the Society for Neuroscience, involved giving rats a constant dose of a cannabis derivative for three weeks.

A control group of rats received no intervention.

In follow-up memory tests, in which rats were placed in a small swimming pool to determine how well they use visual cues to find a platform hidden under the surface of the water, the treated rats did better than the control rats in learning and remembering how to find the hidden platform.
