CBD Improves Blood Flow to Brain’s Hippocampus Significantly, New Study Reveals

We're always excited when scientists discover more amazing things about CBD and Hemp!

Especially when findings could be an important revelation for diseases that affect memory, such as Alzheimer’s disease and post-traumatic stress disorder (PTSD).

Get ready, we're gonna put on our nerd hats for this one... 🤓

In this particular study, published in the Journal of Psychopharmacology, researchers investigated how CBD influences blood flow in different regions of the brain's memory processing area.

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."

15 healthy young adult participants, with little or no history of cannabis use, were selected for this randomized controlled study.

On different occasions, separated by at least a week, each participant was given a 600mg dose of oral CBD or a placebo.

Researchers measured blood flow to the hippocampus using ‘arterial spin labelling’ – an MRI technique which measures fluctuations in the 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.

In the prefrontal cortex, however, the area of the brain used for planning and decision making, CBD caused a significant increase in blood flow in the orbitofrontal cortex.

Dr. Bloomfield added:

“To our knowledge, this is the first study to find that CBD increases blood flow to key regions involved in memory processing, particularly the hippocampus.

“This supports the view that CBD has region-specific blood flow effects in the human brain, which has previously been disputed.

“If replicated, these results could lead to further research across a range of conditions characterized by changes in how the brain processes memories, including Alzheimer’s disease, along with schizophrenia and post-traumatic stress disorder.”

This is great news for CBD! 

But thanks to this study, we could soon see CDB being widely used as a natural solution for neurological and psychological conditions, as well!

In fact, whenever we have a headache or migraine, we massage our temples with a little bit of our Organic Full-Spectrum CBD Cream.

We always recommend it to our customers if they suffer from headaches or migraines, and it helps tremendously.

Now we know why 🤓
