Psilocybin for Treatment-Resistant Depression: The Evidence

For the 30% of depressed patients who don't respond to antidepressants, psilocybin offers new hope.

Psilocybin for Treatment-Resistant Depression

Direct Answer: Yes. The Johns Hopkins 2020 trial found 71% of treatment-resistant depression patients showed significant response to psilocybin therapy, and 54% were in full remission at 4 weeks.

What Is Treatment-Resistant Depression?

Treatment-resistant depression (TRD) is defined as depression that has not responded to at least two adequate antidepressant trials. It affects approximately 30% of all depressed patients — roughly 100 million people worldwide.

Why Psilocybin Works When Antidepressants Don't

Antidepressants manage serotonin levels. Psilocybin works differently: it promotes neuroplasticity (growing new neural connections), resets the Default Mode Network's rumination loop, and allows emotional processing of the underlying causes of depression.
