404 ‒ Mental health beyond neurotransmitters: hormones in psychiatry, psychedelic therapies, & more
In a Nutshell
Psychiatrist Lionus advocates integrating endocrinology with traditional psychiatry, arguing that hormones like estrogen, testosterone, thyroid, and cortisol are foundational regulators of mood, cognition, and neuroplasticity that neurotransmitter-focused treatments overlook. Modern environments disrupt these biological systems through circadian disruption, chronic stress, and social isolation, narrowing distress tolerance and driving rising mental health issues. Psychedelic therapies show promise for conditions like PTSD and end-of-life anxiety but carry unpredictable risks requiring careful set-and-setting protocols and realistic expectations about variable patient responses.

Peter Attia welcomes Lionus, a psychiatrist with 35 years of experience who made a recent pivot to integrate endocrinology with traditional psychiatry. Lionus describes himself as a humanistic existential-oriented psychiatrist who practices psychopharmacology as a way to make a living, with expertise in bipolar spectrum disorders.
After 30 years in practice, Lionus felt he was in a rut and wasn't learning as much as desired. The pivot toward integrating endocrinology is recent, though he has thought deeply about the direction. He describes himself as fortunate to have chosen psychiatry and values the opportunity to know human beings on a deeper level.
Lionus found that psychopharmacology was perceived ambivalently even in successful cases. Patients often felt medication was undesirable even with spectacular symptom reduction. The organizing principle became that psychiatry aims at reduction of symptoms but not restoration of the full human experience that makes life most worthwhile.
Most psychiatrists would agree that there's unusual struggle even in cases of dramatic improvement, and encouraging patients to continue with chronic treatment when needed is often challenging, particularly with bipolar disorder.
Lionus emphasizes that understanding the patient is always greater than any provider's ability to understand them. The nature of a human being is unique and remarkable, requiring progressive layers of insight and reinterpretation of misinterpretations.
