Study shows that CBD may improve memory function
The team used a randomized, crossover, double-blind study in which 15 healthy young adults with little or no history of Cannabis use received CBD
Researchers at University College London found that a single dose of CBD increases blood flow to the part of the brain associated with memory function.
As reported in the Journal of Psychopharmacology in August, the investigators found that 600 mg of oral CBD increases cerebral blood flow (CBF) to important regions of the brain involved in memory processing, particularly in the hippocampus.
The team used a randomized, crossover, double-blind study in which 15 healthy young adults with little or no history of Cannabis use received CBD or a placebo. Using a magnetic resonance imaging technique called arterial spin labeling, which measures changes in blood oxygen levels, the researchers showed a significant increase in CBF in the hippocampus.
Working memory function was assessed by asking test subjects to count forward or backward in random amounts, and episodic memory was tested with a prose recall task.
Although there were no differences in task performance, the CBD-induced increases in hippocampal CBF were associated with reduced reaction time in some of the countdown-related memory tasks.

The researchers concluded that the finding may point to uses for 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 replicated, these results could lead to further research into a range of conditions characterized by changes in how the brain processes memories,” said the study's lead author, Dr. Michael Bloomfield.
