# Primary care prescribers of GLP-1s at therapeutic weight-loss doses lack psychiatric competency to monitor for CNS effects, creating structural risk of anhedonia in patients without psychiatric support

GLP-1 receptors are densely distributed in VTA, nucleus accumbens, insula, and prefrontal cortex—psychiatric-relevant brain circuits. The drugs function as dopaminergic modulators, not just metabolic agents. However, psychiatrists are managing patients prescribed GLP-1s by primary care/endocrinology without understanding CNS mechanisms, dosing nuances, or psychiatric adverse effects. The competency gap creates structural risk: wrong prescriber (primary care optimizing for weight loss), wrong dose (therapeutic doses creating high tonic suppression), wrong monitoring (no psychiatric assessment for anhedonia). Primary care prescribers optimize for the measurable metric (weight loss, HbA1c) while externalizing the psychiatric cost. Osmind recommends: 'Psychiatrists should consider prescribing GLP-1s directly for SUD and mood disorders, not outsourcing to primary care.' The article identifies this as a structural misalignment where the prescribing system optimizes for one outcome while creating unmonitored harm in another domain. This is analogous to Belief 3's structural misalignment thesis: systems optimize for measurable proxies while externalizing costs to domains outside their competency.


## Extending Evidence

**Source:** Psychopharmacology Institute Q1 2026 Review

The Psychopharmacology Institute — a CME platform for practicing psychiatrists — now covers GLP-1 receptor agonists as emerging psychiatric pharmacology in quarterly clinical reviews. This signals that professional psychiatric education is actively incorporating GLP-1 into the psychiatric medication framework, moving beyond endocrinology-only prescribing. However, the review does not provide clinical screening protocols for psychiatrists evaluating patients already prescribed GLP-1s by other providers, indicating the competency gap persists at the protocol level despite conceptual recognition.

## Extending Evidence

**Source:** Dr. Will Sauvé, Osmind CMO

Osmind CMO Dr. Sauvé frames competency gap as existential for psychiatry: 'If our field of psychiatry does not get a hundred percent ahead of how this GLP thing works, then we're going to be left behind.' Identifies specific gap: psychiatrists managing GLP-1-prescribed patients without understanding central mechanisms, dosing nuances, or psychiatric side effects.


## Supporting Evidence

**Source:** Psychiatric News (APA), February 2026

APA's Psychiatric News (February 2026) recommends GLP-1 RAs as second-line AUD treatment requiring metabolic comorbidity, despite JAMA Psychiatry 2025 showing 41.1% reduction in heavy drinking days (NNT 4.3) in AUD + obesity population. The conservative framing (second-line, comorbidity required) contrasts with evidence supporting first-line efficacy. Individual psychiatrists prescribing to >60 patients report 60-70% response rates for alcohol and nicotine reduction, but APA-adjacent guidance maintains naltrexone/acamprosate as first-line despite inferior NNT.
