Psychedelics: How They Act on the Brain to Relieve Depression

Up to 30% of people with depression don’t respond to treatment with antidepressants. This may be down to differences in biology between patients and the fact that it often takes a long time to respond to the drugs – with some people giving up after a while. So there is an urgent need to expand the repertoire of drugs available to people with depression.

In recent years, attention has turned to psychedelics such as psilocybin, the active compound in “magic mushrooms”. Despite a number of clinical trials showing that psilocybin can rapidly treat depression, including for cancer-related anxiety and depression, little is known about how psilocybin actually works to relieve depression in the brain.

This article, published in theconversation.com, shows how two recent studies, published in The New England Journal of Medicine and Nature Medicine, have shed some light on this mysterious process.
