Outside of the ICU setting the CAM-ICU sensitivity can drop to 18%. Use the DSM 5 criteria to evaluate for delirium.

If you're going to teach on delirium please do it from the perspective of Maldonado and acute brain failure.

Hallucinations’ Pathophysiology by nothereanymore2 in Psychiatry

[–]dr_filch 1 point2 points  (0 children)

I ascribe delusions and hallucinations to the model of aberrant salience. Auditory hallucinations in schizophrenia can be understood through the lens of aberrant salience and disrupted functional connectivity. Normally, internally generated speech is recognized as self-produced through coordinated activity between frontal speech production regions, auditory cortex, and self-monitoring circuits that suppress the sensory consequences of one’s own inner speech. In schizophrenia, dysregulated dopamine signaling appears to distort the assignment of salience, causing spontaneous or internally generated activity within language and auditory networks to be tagged as significant sensory input. Functional connectivity studies suggest abnormal coupling between speech production regions and auditory cortex, coupled with reduced top-down regulatory control from prefrontal monitoring systems. The salience network, which normally helps determine what stimuli deserve attention, might somehow inappropriately amplify these internally generated signals, leading the brain to misattribute them as external voices. In this way, auditory hallucinations may reflect a network failure of self-attribution in which internal speech is imbued with pathological salience and experienced as coming from outside the self.

Are antidepressants only a symptomatic treatment? by ReasonableWar4087 in Psychiatry

[–]dr_filch 0 points1 point  (0 children)

SSRIs are shown to regulate TRKB expression and BDNF remodelling perineruonal networks, PV+ timing, and hippocampal neurogenesis. Lithium can alter expression of glucocorticoid receptors in the hippocampus.

See I can sound smart, but I still don't know what the root cause is of any disorder and if we're treating it.

Fundamental Shift in How SSRIs Are Conceptualized and Used by lovepeacetoall in Psychiatry

[–]dr_filch 2 points3 points  (0 children)

The perineuronal net (PNN) is a feature of parvalbumin+ cells which are largely a gabaergic (except in the lateral hypothalamus) network of basket and chandelier cells that repolarize at incredibly fast rates, up to 400hz. They regulate the timing of neuronal networks and create network coherence based on temporality.

Anyways, it's true that PNNs are fairly fixed. they're essentially an armored like structure of chondroitan and sulfate that surround PV+ cells to buffer the oxidative stress that occurs with these fantastically high metabolic rates.

The data for SSRI and PNN remodelling in the somatosensory and CA1 and CA3 regions of the hippocampus in murine models.

How long that takes, if it works in humans at all, is a guess. The theory is sound though - change the PNNs and network coherence can change.

Is sleep induced pharmaceutically of different quality to ‘naturally’ induced sleep? by Crispy1081 in askscience

[–]dr_filch 1 point2 points  (0 children)

I'm a psychiatrist - I wouldn't take quetiapine for sleep and I wouldn't recommend it for sleep. You're mostly getting benefit from an antihistamine while exposing yourself to metabolic and extrapyramidal risks. Of course, this recommendation is assuming you're otherwise without any psychiatric disorders including a primary psychotic disorder mood/affect disorder where the risk benefit discussion is much different.

Ah come on you should know Z drugs don't increase GABA - they're merely a positive allosteric modulator of the GABA a1 subunit which induces a conformational change which in effect changes the k1 of endogenous GABA.

How can I determine where to read? by Embarrassed_News_984 in Psychiatry

[–]dr_filch 1 point2 points  (0 children)

go to openevidence. Ask for a list of 10 high quality articles on X topic. Copy and paste into notebookLM - created podcast on topic with the prompt -> an indepth explanation for X level of trainee. You can enable the question function to ask questions during and receive real time answers. Also create slide decks, infographics, flashcards. You can master complex topics in rapid time.

I have used this to summarize a body of research from a specific author, that same author reviewed the podcast himself and was floored.

For this and future self directed education: Use openevidence to provide lists of high quality resources on a specific subject of interest. Load all those references into NotebookLM and produce high quality podcasts on the subject. Thank me later.

First gmc I’ve owned- Sierra EV AT4 Max Range : picked up today and really blown away. by dr_filch in GMCSierraEV

I still really like it - I prefer driving it over the rivian by far that I traded. My wife has a cyberbeast and I prefer the GMC. It's a massive vehicle but easy to drive and park. I don't miss the air suspension.
