Beyond Chemical Reductionism: How New Depression Research Supports Embodied Medicine

Review Article

Abstract

A landmark systematic umbrella review by University College London researchers published in Molecular Psychiatry found no solid scientific evidence supporting the serotonin theory of depression, challenging the foundational "chemical imbalance" hypothesis underlying SSRI treatment and opening new avenues for alternative therapeutic approaches.

This essay examines how the collapse of the chemical imbalance theory validates embodied medicine approaches to depression that recognize the inseparable unity of mind, body, and environment, moving beyond Cartesian dualism toward holistic healing paradigms.

We synthesize findings from the UCL review with phenomenological research, embodied cognitive science, and integrative healing approaches, drawing particularly on the work of Thomas Fuchs, Kevin Aho, and Julian Ungar-Sargon's critique of reductionist medicine.

The convergence of evidence demonstrates that depression emerges not from isolated neurochemical deficiencies but from disruptions in embodied consciousness, intercorporeality, and the person's dynamic engagement with their world. Phenomenological research reveals depression as involving spatial-temporal disruption, corporeal alienation, and breakdown of meaning-making processes. Body-oriented psychotherapies and embodied interventions show promise as alternatives to purely pharmacological approaches.

Conclusions: The collapse of the serotonin theory represents more than a scientific correction—it signals a paradigm shift toward understanding depression as a meaningful response of embodied persons to life circumstances rather than a brain disease. This supports therapeutic approaches that address the person's total existential situation, restore embodied agency, and honor the sacred dimensions of healing encounters. Future research should focus on developing integrative frameworks that transcend the artificial mind-body split while maintaining scientific rigor.
