You may have heard that Dr. Google now has some serious competition. It comes from artificial intelligence. Chat GPT is a text generating program that was trained to respond to prompts from users like you and me. What will it say to our psychiatry patients? I gave it some prompts to find out.

In 2012 the Supreme Court heard two related cases involving adolescents convicted of murder and sentenced to life in prison without parole because of mandatory minimum sentencing guidelines in their states. One of the boys, Evan Miller along with an accomplice, had beat a man unconscious with a baseball bat after a fight that ensued when the man awoke to find Miller robbing him. Miller and his friend then decided to set fire to the home to cover up the evidence. This resulted in the man’s death. The second petitioner, Kuntrell Jackson, had accompanied two other boys to a convenience store in order to rob it. During the robbery, one of the boys, not Jackson, shot and killed the clerk.
Both boys were convicted and were sentenced according to minimum sentencing guidelines to life in prison without parole. The decision that the court was asked to make was not whether the boys should have been convicted, but instead, whether the sentencing guidelines that resulted in them being given life without parole constituted cruel and unusual punishment.

PsyDactic - WTF - Thalamus
play

04/24/24 • 22 min

The thalami are bilaterally symmetrical structures in the subcortical part of the brain that are cradled by the basal ganglia. They are major hubs of pretty much everything your brain does and all of the sensory information coming into the brain with the exception of smell.

More primitive models of the brain visualized it as a bunch of relatively isolated modules, each specialized to perform a single task when queried and able to send that information to wherever it should go. More modern ideas propose a more integrated picture, with various regions of the brain contributing to a more diffuse process through parallel connections with other network communities and hubs. It appears that nearly every integrated process in the brain is influenced at some level by thalamic modulation. You could characterize the Thalamus as a brain wide gateway to the cortex, modulator and mediator of inputs, coordinator of feedback, relay between higher cognitive areas, manager of brainstem nuclei, and facilitator of attention.

PsyDactic - Catatonia - Introduction and Overview
play

In this episode, I introduce a diagnosis that is not a diagnosis. By that, I mean that it is a condition that we may find our patients in, but it is not considered to be a diagnosis by itself, like major depressive disorder or schizophrenia are considered to be diagnoses. I am talking about catatonia, a condition characterized by either a lack of interaction with the world or as purposeless interaction with the world.

The Narrative Fallacy describes our tendency to find meaning, connections, and causal relationships where they do not necessarily exist. In this episode, Dr. O'Leary had the pleasure of interviewing Dr. Alexey Tolchinsky.
He recently published a paper called “Narrative fallacy and other limitations of psychodynamic case formulation.” Dr. Tolchenski did not invent the idea of the Narrative Fallacy, but he is working to apply this idea to his own clinical practice. We could all benefit from recognizing the ways that Narrative Fallacy plays out in our lives. The great thing about these ideas is that they are so generalizable. The Narrative fallacy is not limited to medicine or science, but can be applied, for example in how we explain to ourselves why our neighbor seems to hate us.

-- 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 interests in autism can result in exactly the wrong medication being given or no medication being given and a worsening of the condition. --

PsyDactic - Neuropsychiatry - Huntington Disease
play

12/03/22 • 30 min

Send us a text

Dr. O'Leary reviews one of the most frustrating diseases that a patient and their family might approach a psychiatrist with: Huntington’s Disease. Huntington’s Disease is a neurodegenerative disorder, which means that over the course of the disease neurons die or cease to function correctly and this worsens over time. The death of neurons in the caudate nucleus and putamen results in choreiform or dance-like movements of the extremities which earned it the moniker “Huntington’s Chorea." Huntington's Disease can result in many psychiatric symptoms and these may start to occur during the prodromal stage before the choreiform movements develop. Sleep disturbances, apathy, executive dysfunction, memory impairment, personality change, irritability and aggression, disinhibition and impulsivity (including hyper-sexuality), depression, mania, delusions, paranoia and other psychotic symptoms, obsessions and compulsions, and most prominently a high risk of suicide.

Stupor, Mutism, and Negativism on the surface appear to have some overlapping features. Of all the features of catatonia that non-experts might be able to describe, stupor and mutism are like the ones. They are also the most common signs. A patient is not entirely unconscious, but they don’t move, they stare forward, they don’t talk, and they don’t follow commands.

PsyDactic - Bush Francis versus the DSM

I originally promised a review of the Bush Francis Catatonia Rating Scale, but while reviewing it, I came across some questions that I think are even more interesting. I will discuss Bush Francis, but I want to do it in a larger context of the challenges that Psychiatrists face with diagnosis in general.
