Research from King’s College London has found that a single dose of the cannabis extract cannabidiol can help reduce brain function abnormalities seen in people with psychosis.
Results from a new MRC-funded trial, published in JAMA Psychiatry, provide the first evidence of how cannabidiol acts in the brain to reduce psychotic symptoms.
Cannabidiol, also referred to as CBD, is a non-intoxicating compound found in cannabis. A purified form of cannabidiol has recently been licensed in the USA as a treatment for rare childhood epilepsies, and a 2017 King’s College London trial has demonstrated cannabidiol has anti-psychotic properties.
However, exactly how cannabidiol may work in the brain to alleviate psychosis has remained a mystery.
“The mainstay of current treatment for people with psychosis are drugs that were first discovered in the 1950s and unfortunately do not work for everyone,” says Dr Sagnik Bhattacharyya, from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN). “Our results have started unravelling the brain mechanisms of a new drug that works in a completely different way to traditional anti-psychotics.”
