Benefits of Hemp THC on the aging adult brain

The strength of communication across different brain regions changes as people age and contributes to age-related memory impairments and cognitive decline. Scientists in Colorado used functional neuroimaging to assess how regular hemp THC use (at least once per week) in adults over 60 years old altered the strength of communication between several brain regions that normally declines with age.

They found that older adults who regularly used hemp THC had stronger communication patterns between three brain regions—the hippocampus, the parahippocampal gyrus, and the cerebellum—compared to non-cannabis using older adults. The stronger connectivity among older hemp THC users resembled that of much younger non-using adults and suggests that hemp THC may protect against some of the age-related declines in brain function.

Although these results are not causal in nature because it wasn’t a randomized, controlled experiment, they provide some of the first human evidence to support observations from rodent studies where small amounts of regular cannabis use protected against age-related brain changes and cognitive decline.
