Allostatic Recalibration Theory (ART): Serotonergic Psychedelics Exert Transdiagnostic Therapeutic Effects by Recalibrating Allostasis to the Environment
SSRN · 6598058
The Takeaway
Most medical theories focus on how psychedelics fix specific neural circuits in the brain. This new theory suggests they actually work by recalibrating allostasis, which is the body total system for managing environmental stress. By resetting this master control, the drugs can alleviate symptoms of psychiatric, immune, and metabolic disorders all at once. It explains why a single dose can have such wide ranging effects on both the mind and the body. This shift in perspective could change how we develop treatments for chronic illnesses that were previously thought to be unrelated. The drug is a whole body recalibration rather than just a mental fix.
From the abstract
Serotonergic psychedelics produce therapeutic effects in clinical trials of diverse neuropsychiatric disorders, and preclinical models of inflammatory, cardiometabolic, and neuropsychiatric diseases. These effects appear largely mediated by the serotonin 5-HT2A receptor (5-HT2AR). How could psychedelics elicit transdiagnostic therapeutic effects through a single receptor across tissues as diverse as the immune, cardiometabolic, and central nervous systems (CNS)? Psychedelic effects are exception
