Renowned psychiatrist illuminates biological roots of mental illness through pioneering research

(Press-News.org) MILANO, Italy, 3 June 2025 – In a comprehensive Genomic Press Interview published in Brain Medicine, Professor Francesco Benedetti shares his transformative journey from confronting childhood awareness of mental illness to becoming a leading figure in psychiatric research. As founder and leader of the Psychiatry & Clinical Psychobiology research unit at IRCCS Ospedale San Raffaele, Dr. Benedetti has dedicated decades to reclaiming psychiatry's rightful place within medical science.

Professor Benedetti's career trajectory reflects both personal conviction and scientific rigor. Despite facing rejection from traditional psychiatric training programs that viewed mental illness as merely "functional," he persevered through an alternative path that ultimately revolutionized treatment approaches for mood disorders. "I see no boundaries between science and everyday clinical work," Dr. Benedetti states, emphasizing his commitment to translating research directly into patient care.

Chronotherapeutics: A Revolutionary Approach to Treatment

The urgent need to help acutely depressed, suicidal patients with bipolar disorder who showed no response to standard antidepressant treatments drove Professor Benedetti and his colleagues toward chronotherapeutics. Their innovative protocols combining environmental stimuli such as light and dark with sleep-wake rhythm manipulations have achieved rapid therapeutic effects in acute depression. These developments emerged from direct clinical observation rather than theoretical speculation.

Professor Benedetti's team pioneered techniques that remain widely used today. Through international lecture tours, he continues teaching colleagues these methods developed in the 1990s, demonstrating how neuroscience research and clinical practice can harmonize effectively. The work has revealed crucial insights into how genetic variants of core clock machinery components including GSK-3β, CLOCK, and hPER3 influence human behavior and brain function.

Uncovering the Immune Connection in Mood Disorders

A pattern of unusual infections and autoimmune conditions among psychiatric patients sparked Professor Benedetti's exploration into immuno-psychiatry. His clinical observations of patients experiencing relapses following fevers and infections led to groundbreaking research on immune-inflammatory mechanisms in mood disorder etiopathogenesis. This perspective gained particular relevance during the COVID-19 pandemic, when Professor Benedetti predicted and subsequently documented post-COVID depression linked to prolonged inflammation.

Current research in Professor Benedetti's laboratory focuses on how gene variants moderate the effects of life events and pathogen exposure on immune-inflammatory setpoints. These mechanisms ultimately impair brain homeostasis, particularly affecting white matter integrity. Through advanced neuroimaging techniques, his team has demonstrated how the interaction between genetic factors, adverse childhood experiences, and low-grade inflammation produces measurable changes in brain structure.

Bridging Molecular Mechanisms and Clinical Reality

Professor Benedetti's approach to psychiatric genomics extends beyond academic interest. By studying functional polymorphisms affecting treatment response, his research has contributed to personalized medicine approaches now offered through pharmacogenetic screening packages worldwide. Notably, variants affecting serotonin promoter, 5-HT2A, COMT, and GSK-3β genes influence both illness course and treatment outcomes.

The integration of brain imaging with genetic analysis has revealed how treatment interacts with gene variants to alter neural responses and brain structure during recovery. This comprehensive approach demonstrates that mood disorders involve complex interactions between biological vulnerability, environmental exposure, and therapeutic intervention. Questions arising from this work include: How might early identification of genetic risk profiles guide preventive interventions? Could immune system modulation become a primary treatment strategy for certain mood disorder subtypes?

Challenging Medical Misogyny and Advancing Women's Health

Beyond his scientific contributions, Professor Benedetti advocates passionately against medical misogyny and the dismissal of women's mental health concerns. He challenges the persistent notion that conditions specific to women represent weakness or hysteria, noting that suicide remains the leading cause of postpartum death in developed nations. This advocacy reflects his broader commitment to reducing stigma by demonstrating that mental illnesses are "deeply rooted in our body malfunction, as it happens in every other branch of medicine."

His research perspective appears endless, driven by exponential progress in neuroscience and the recognition that modern psychiatry remains "still in its infancy." Professor Benedetti continues observing patients, asking questions, and applying new methodological advances to unlock the biological basis of mental suffering. The rewards come not from academic accolades but from seeing other researchers build upon his findings to increase patient benefits.
