Psilocybin-assisted therapy for the treatment of resistant major depressive disorder (PsiDeR): protocol for a randomised, placebo-controlled feasibility trial

BMJ Open December 1, 2021 James Rucker, Hassan Jafari, Tim Mantingh et al. 23 citations

A randomized, placebo-controlled trial is testing the feasibility of psilocybin-assisted therapy for people with major depressive disorder who have not responded to at least two prior treatments. Up to 60 participants in London, UK receive either 25 mg psilocybin or a placebo in a single dosing session, along with psychological therapy. The primary outcomes are recruitment rates, dropout rates, and variance in depression scores measured by the Montgomery Asberg Depression Rating Scale at 3 and 6 weeks. The trial also collects neuroimaging and omics data and offers an open-label extension dose of psilocybin.

Psilocybin for dementia prevention? The potential role of psilocybin to alter mechanisms associated with major depression and neurodegenerative diseases

Pharmacology & Therapeutics April 6, 2024 Zarah R. Haniff, Mariia Bocharova, Tim Mantingh et al. 16 citations

Major depression increases the risk of later dementia, and late-life depression may be an early sign of dementia. Adult hippocampal neurogenesis (AHN), the lifelong birth of new neurons in the dentate gyrus, supports learning, memory, and mood. Microglia, the brain's immune cells, regulate AHN, and disruptions in AHN and microgliosis are linked to both depression and neurodegenerative diseases. Psychedelics like psilocybin, a serotonergic agonist with rapid antidepressant effects, may promote neuroplasticity and modulate microglial function. This narrative review examines evidence that psilocybin could affect AHN and microglia, potentially altering the progression from major depression to dementia in at-risk individuals.
