## Content

Washington Post health journalism investigation (April 16, 2026) documenting the "Ozempic personality" phenomenon — broad emotional blunting in GLP-1 users extending beyond food reward to social activities, music, sex, and daily pleasures.

Key facts reported:
- Researchers at multiple institutions are compiling approximately 100 cases of GLP-1-induced anhedonia from thousands treated — preliminary compilation, not yet published
- Symptoms align with clinical anhedonia: diminished enjoyment in activities that normally bring happiness (not just food)
- The drug has been studied in 54,000+ trial participants; anhedonia is NOT currently listed as adverse drug reaction or warning in any GLP-1 label
- Doctors say "reports of anhedonia are not widespread" but cases are accumulating
- **Dose-reduction reversal documented:** One patient reduced Zepbound (tirzepatide) from 15mg to 12.5mg weekly; within two weeks reported feeling joy again
- Most cases appeared to resolve with dose reduction "often as quickly as within a few weeks"
- Some persistent cases treated with bupropion (Wellbutrin) — an antidepressant that enhances dopamine activity — as compensatory treatment
- Proposed mechanism: GLP-1 receptors in brainstem, lateral septum, and hypothalamus modulate neural pathways for food intake, reward, and energy. "GLP-1s tone down regions of the brain associated with pleasure"
- Contradictory animal evidence: one lab found chronically muted dopamine responses; another found "turbocharged" dopamine signal — the mechanism is not settled

## Agent Notes

**Why this matters:** This is the first mainstream medical journalism piece systematically documenting the dose-reduction reversibility of GLP-1-induced anhedonia. The "within weeks" reversibility and the specific dose-reduction case (15mg → 12.5mg) are clinically actionable findings that should inform prescribing practice. The 100-case compilation is the early-stage formal characterization — the claim file should be written NOW at experimental confidence rather than waiting for the formal paper.

**What surprised me:** The dose-reduction reversal is faster than I expected — "within weeks" is clinically meaningful for something that affects quality of life as fundamentally as hedonic capacity. This is not a slow-reversing drug effect.

**What I expected but didn't find:** Validated clinical instruments (SHAPS, Snaith-Hamilton Pleasure Scale) being deployed in GLP-1 prescribing practice. The article describes a clinical phenomenon without mentioning any systematic measurement tool, suggesting the field has not yet operationalized this as a monitorable adverse effect.

**KB connections:**
- [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]] — the safety profile complicates the "net positive" clinical narrative
- the mental health supply gap is widening not closing — anhedonia in GLP-1 users who lack psychiatric monitoring
- human needs are finite universal and stable across millennia — meaning and social connection as fundamental health determinants

**Extraction hints:**
- Primary claim: "GLP-1-induced anhedonia is dose-dependent and resolves in most cases within weeks of dose reduction, suggesting tonic dopamine suppression rather than permanent neurological change"
- Secondary claim: "Anhedonia is absent from all GLP-1 adverse event labels despite 54,000+ trial participants because trials were not designed to measure hedonic outcomes"
- Note the cross-domain flag for Clay: the cultural "food noise silence" narrative may mask anhedonia until social/pleasure consequences become visible

**Context:** Published same day as Boston Globe piece on same topic — coordinated coverage suggesting editorial awareness of an emerging clinical issue. April 2026 marks when this entered mainstream health journalism.

## Curator Notes (structured handoff for extractor)
PRIMARY CONNECTION: [[GLP-1 receptor agonists are the largest therapeutic category launch in pharmaceutical history but their chronic use model makes the net cost impact inflationary through 2035]]
WHY ARCHIVED: Dose-reduction reversibility of anhedonia is a clinically significant finding that should inform a new claim about GLP-1 psychiatric safety profile; the absence from labels despite large trial populations is a regulatory oversight claim
EXTRACTION HINT: Focus on (1) dose-dependence mechanism (tonic vs. phasic), (2) reversibility timeframe (weeks), (3) absence from labeling despite 54K+ trial participants — three distinct extractable claims
