Depression and anxiety impose large economic costs, and many patients do not respond to traditional antidepressants. A single dose of DMT, the main psychoactive compound in ayahuasca, initially increased anxiety-like behaviors in adult male rats but later reduced anxiety by speeding the extinction of conditioned fear memories. DMT also decreased immobility in the forced swim test, a standard measure of antidepressant-like effect. These results indicate that DMT produces both antidepressant and anxiety-reducing behavioral effects in rodents, supporting further research into ayahuasca and similar psychedelics as potential treatments for depression and PTSD.
