What is it about?

We tested two types of therapy for depression: psychedelic therapy with psilocybin and a standard anti-depressant medication (escitalopram). Both were good anti-depressants, but we found that the escitalopram group had reduced responses to emotional stimuli.

Why is it important?

We think this shows that psilocybin therapy and standard anti-depressants have very different brain mechanisms, and produce their anti-depressant effects in different ways.

Perspectives

We hope this article helps make the case for why psychedelic-based therapies should be more widely available, as it shows that they are effective anti-depressants, and preserve emotional function.
