Dr. O'Leary explores the neuroscience of dissociation, defining it as a degenerate concept that refers to a wide range of functional disconnections within the brain rather than a single clinical entity. The discussion moves from the standard medical definitions—such as depersonalization, derealization, and amnesia—toward a broader view of dissociation as a neurobiological defense mechanism that uses sensory attenuation to mana...

In December 2025, the FDA authorized  the Flow F100, an innovative at-home wearable headset that utilizes transcranial direct current stimulation (tDCS) to treat major depressive disorder. Unlike traditional pharmaceuticals that act systemically, this device targets the dorsolateral prefrontal cortex with localized electricity to modulate neuronal excitability and address the asymmetry hypothesis of depression. While the Empower st...

PsyDactic welcomes The Game Theorist's Guide to Parenting co-author, Kevin Zollman who discusses game theory as the science of strategic thinking. We explore how mathematical models like the Prisoner’s Dilemma and mechanism design can be used to manage family dynamics by creating win-win solutions rather than competitive, zero-sum outcomes. The conversation highlights practical techniques such as "I cut, you pick" fo...

Dr. O'Leary proposes Childhood Deficit Disorder as a way to conceptualize the rise in mental health issues among modern youth, exploring how systemic changes in culture and environment contribute. He contrasts the "free-range" parenting style prior to the 1980s, which fostered autonomy and resilience, with the modern trend of intensive, managerial parenting driven by economic anxiety and a "culture of fear"...

Dr. O'Leary explores the history of clozapine, highlighting its initial revolutionary impact as the first atypical antipsychotic, followed by a ban on its use, followed by its re-emergences as a strictly monitored medication, and then culminating in new recommendations that greatly encourage its use. The discussion details the severe side effects that led to its initial discontinuation,  and then emphasizes other critical but ...

This episode includes a fascinating interview with a researcher in ultrasound, Dr. Michael Canney who is an acoustics researcher the chief scientific officer at a French company named Carthera (https://carthera.eu/) and they make ultrasound devices that can disrupt the blood-brain barrier in order to let medicines into the brain that otherwise could only get through in very small amounts.

We talk more broadly about the exp...

This PsyDactic podcast episode, hosted by Dr. O'Leary, delves into the complex and often controversial topic of diagnosing Pediatric Bipolar Disorder and its differentiation from other conditions, particularly Disruptive Mood Dysregulation Disorder (DMDD). Dr. O'Leary, a Child and Adolescent Psychiatry Fellow, explores the DSM-5-TR diagnostic framework, the history of Pediatric Bipolar diagnosis, the debate surrounding ir...

Functional Neurological Disorder was previously called Conversion Disorder or psychogenic neurological symptoms and is a condition in which a patient develops any number of neurological symptoms (such as loss of ability to move or seizure like episodes or inability to feel parts of their body or phantom pain) that cannot be explained by a clear lesion in the nervous system.  It was called conversion disorder because it was previous...

"People are 14 times more likely to die during a hospital stay than outside of hospital for inpatient psychiatry."  In the last episode, I shared an episode of Psychiatry Boot Camp, which is a podcast created by Dr. Mark Mullen to help medical students and junior residents hone their psychiatric skills.  Mark interviews some of the most competent and amazing psychiatrists our country has to offer.  I am excited that Mark ...

In the last episode, Dr. O'Leary interviewed the creator and host of the Psychiatry Bootcamp Podcast, Dr. Mark Mullen, who is currently a psychiatry clerkship director at St. Louis University School of Medicine.  He created this podcast after discovering a dearth of resources available for medical students and junior psychiatry residents to prepare them for their transition to practice. 

He graciously allowed PsyDactic to inclu...

Dr. O'Leary is excited to introduce you to  Psychiatry Boot Camp (PBC), a podcast created by Dr. Mark Mullen during his psychiatry residency to help prepare medical students for psychiatry residency. It covers fundamental topics in psychiatry and inspires young psychiatrists to think critically about their approach to the field. The curriculum is based on published literature on psychiatry crash courses and boot camps, and fea...

--In today's episode, Dr. O'Leary explores agonists, inverse agonists, partial agonists, and antagonists. These terms describe how molecules bind to receptors and either increase, decrease, or prevent changes in receptor signaling. Agonists increase receptor activity, with full agonists like dopamine and serotonin raising activity to its maximum. Partial agonists can increase activity in the absence of full agonists but d...

--Dr. O'Leary discusses the term Transference, and if you listen until the end, he relates it to some computational neuroscience.   Transference is a historically loaded term.  Transference is supposed to be an unconscious process, so it can not really be observed, only inferred, so this means that both the definition of transference and any instance of it in psychotherapy is dependent upon the therapist’s model and their part...

  -- More recently I have faced the diagnostic conundrum of catatonia in autism, and that is what I want to explore in more excruciating detail today.  There is surprisingly little literature on the subject, and that is concerning because being able to identify and treat catatonia can be life-saving, not to mention life-altering for patients and their caretakers.  Misidentifying catatonia as mere aggression or highly limited intere...

  --  Dr. O’Leary interviews forensic psychiatrist and author Dr. Michael Schirripa about his career as a forensic psychiatrist, the release of his first thriller, Mindhunt, and his podcast Mindhunting.  Dr. Shirripa explores how his love of literature influenced his decision to pursue forensic psychiatry and ultimately resulted in his creation of an international thriller with an ambitious forensic psychiatrist as the main charact...

- - In the world of psychotropic medication, the question is not just whether it works or not, but whether it works better than a placebo and whether the effect size is clinically significant and the benefits outweigh the risks.  In the case of MDMA (aka molly or ecstasy), the effect size for improving post-traumatic stress disorder symptoms reported by researchers has been very large.  Often it is found to be two to three times hi...
