A recent study set out to investigate how CBD influences cerebral blood flow in regions of the brain involved in memory processing.
It also set out to determine if the effects of CBD on the CBF were linked with differences in working and episodic memory task performance.
The findings showed a significant increase in hippocampal CBF after CBD which contrasts with two previous SPECT studies which actually found a decrease in CBF in healthy, and anxiety disorder participants. Several possible explanations were cited such as an increased dosage of 600 vs 400mg of CBD.
There were no differences in memory task performance, but there was a significant correlation whereby greater CBD-induced increases in orbitofrontal CBF were associated with reduced reaction time on the 2-back working memory task.
It's a really interesting piece of research and it highlights yet again, how important CBD can be in making the lives of those who may be suffering a little bit easier.
