Marijuana Boosts Memory in Aging Brains

Marijuana Boosts Memory in Aging Brains

According to a study released in Nature Medicine, marijuana may boost cognitive function and memory in elderly brains–at least in mice.

In past years, the focus of marijuana research has looked at effects of cannabis consumption in teenagers and young adults. Findings concluded that cannabis use in young brains is detrimental–and this most recent study did corroborate those findings.

However, when it comes to elderly brains and cannabis, it’s a completely different story.

Andreas Zimmer, a professor of molecular psychiatry at the University of Bonn in Germany, along with a team of researchers, found “a dramatic improvement in cognitive functions” in mice given daily, low doses of THC for a month.

Researchers included young, mature, and elderly mice in the study and performed a number of behavioral experiments. In some of the experiments, THC seemed to improve the memory in the older mice to such a degree that their cognitive function appeared to be as good as those of young mice.

In one of the tasks, mice were placed in a water maze with a hidden platform that allowed them to escape. In the control group, (mice who were not given THC) the mature and old mice took longer to climb out than the young mice. Among mature and elderly mice that had been given THC, they found the platform faster than the control mice in corresponding age groups. Young mice given THC took longer to learn where the platform was hidden.

The findings raise the possibility that cannabinoids might act as anti-aging molecules in the brain. “That is something we absolutely did not expect: the old animals [that received] THC looked most similar to the young, untreated control mice,” Zimmer said.

However, other scientists cautioned that extrapolating findings in mice to humans is premature. “This well-designed set of experiments shows that chronic THC pretreatment appears to restore a significant level of diminished cognitive performance in older mice, while corroborating the opposite effect among young mice,” Susan Weiss, director of the Division of Extramural Research at the National Institute on Drug Abuse who was not involved in the study, wrote in an e-mail to Scientific America. Nevertheless, she added, “While it would be tempting to presume the relevance of these findings [extends] to aging humans…further research will be critically needed.”

Zimmer and his colleagues have already been awarded funding to begin a clinical trial studying the effects of THC in elderly adults with mild cognitive impairments.

“If we can rejuvenate the brain so that everybody gets five to 10 more years without needing extra care, then that is more than we could have imagined,” study co-author Andras Bilkei-Gorzo told The Guardian.
