CBD DOES help the mind: Study finds that cannabidiol improves blood flow to parts of the brain associated with memory and decision-making
Researchers from University College London (UCL) found that CBD increased blood flow to the main area responsible for memories and learning.
Researchers gave 15 participants with no history of cannabis use 600 mg of CBD on different occasions for a week and then 600 mg of a placebo. The dose came in the same capsules so the patient didn’t know if they where receiving CBD or the placebo
MRI scans showed CBD increased blood flow to the hippocampus, responsible for memories and the orbitofrontal cortex, responsible for decision-making
The team says this could offer therapies for those who suffer conditions that affect memory, such as Alzheimer’s disease and post-traumatic stress disorder.
In the study, published in the Journal of Psychopharmacology, researchers set out to investigate how CBD influences cerebral blood flow in different regions on 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. 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.”
Over the course of a week 15 adults where given 600mg of oral CBD or placebo
Next, researchers used an MRI brain scanning technique called arterial spin labeling, which measures blood oxygen level changes.
Results showed that CBD significantly increased blood flow in the hippocampus and the orbitofrontal cortex, the latter of which plays a role in decision-making.
‘Cannabidiol is one of the main constituents of cannabis and is gaining interest for its therapeutic potential,’ Bloomfield said.

Sometimes you will never know the value of a moment until it becomes a memory……
