Marijuana may lower the risk of neurocognitive decline in
people with HIV, according to a new groundbreaking study. The authors of the
study called for more research into whether the protective effects of marijuana
could extend to the general aging population.
There is some evidence that cannabis may reduce damage to brain neurons by decreasing inflammation and neurotoxicity. Both HIV and aging are associated with increased inflammation in the brain. Together, aging with HIV seems to have an additive effect, leading to a much higher risk of cognitive impairment.
The study, published in the Journal of Acquired Immune Deficiency Syndrome, found that people with HIV who used cannabis were significantly less likely to experience neurocognitive impairment (NCI) compared to patients who had no history of marijuana use.
When they looked at types of cognitive performance, the researchers
found that cannabis use was associated with higher verbal fluency and learning
An estimated 60% of people with HIV have used marijuana. Many patients use it to reduce symptoms such as neuropathic pain, nausea, mood problems, poor appetite, and weight loss. But these results show that it may have long-term benefits as well.
“Taken together, this literature cumulatively suggests there may be some therapeutic potential of compounds that target the cannabinoid system through modulation of neurotoxic and inflammatory processes in HIV disease and other neuroinflammatory diseases,” the authors wrote.
While the study looked at people with HIV, the authors suggested that the protective effects of cannabis on the brain could apply to all older adults, and that more research is needed to examine the possible protective effects of cannabis on the aging brain.
