A single dose of cannabidiol (CBD) and CBG hemp Van Buren help to increase blood flow to the hippocampus, finds a new study. This is an important area of the brain associated with memory and emotion. Researchers say the findings could be an important discovery for conditions that affect memory. This may include Alzheimer’s disease and post-traumatic stress disorder (PTSD) and could help better target therapies.
In the study, published in the Journal of Psychopharmacology, researchers set out to investigate how CBG hemp Van Buren influences cerebral blood flow in different regions of the brain involved in-memory processing.
Lead author, Dr. Michael Bloomfield (UCL Psychiatry) said: “Cannabidiol is one of the main constituents of cannabis and is gaining interest for its therapeutic potential. There is evidence that CBD may help reduce symptoms of psychosis and anxiety. Hence, there is some evidence to suggest that CBD may improve memory function.
Additionally, CBD changes how the brain processes emotional memories, which could help to explain its reputed therapeutic effects in PTSD and other psychiatric disorders. However, the precise mechanisms underlying the effects of CBD on memory are unclear.”
For the randomized controlled study, 15 healthy young adult participants, with little or no history of cannabis use were selected. On different occasions, separated by at least a week, each participant was given 600mg of oral CBD or a placebo. The doses came in identical capsules, so participants did not know which one they were taking on which occasion.
Researchers measured blood flow to the hippocampus using ‘arterial spin labeling’. In conclusion, it is a magnetic resonance imaging (MRI) brain scanning technique that measures changes in blood oxygen levels.
CBD significantly increased blood flow in the hippocampus. However, CBD did not cause significant differences in blood flow in other regions of the medial temporal lobe (MTL), of which the hippocampus is a significant component.
