CBD Increases Blood Flow to the Hippocampus and May Improve Memory

by Aug 4, 2021Hemp & CBD Use

In a placebo-controlled double-blind study with 15 healthy volunteers, researchers at University College in London found that acute CBD use increased cerebral blood flow in areas associated with memory, just 3 hours after use.

While this showed exciting gains in measurable flow that is associated with memory performance, researchers did not find measurable performance gains of any significance in their 15 subjects with limited testing.

Reaction time was significantly-reduced for one of the recollection tasks, but performance results were otherwise insignificant. Investigators concluded:

These findings suggest that CBD increases CBF [cerebral blood flow] to key regions involved in memory processing, particularly the hippocampus. These results identify potential mechanisms of CBD for a range of conditions associated with altered memory processing, including Alzheimer’s disease, schizophrenia, post-traumatic stress disorder and cannabis-use disorders.

If CBD does indeed hold secrets to improved memory performance or treatment for memory-related disease, we need more study to prove it. Nevertheless, what we see so far appears very exciting.
