Theory Briefing
- GLP-1 drugs like Ozempic reduced anhedonia in people who already had depression, according to researcher Neal at MUSC.
- The concern is whether the same reward-dulling effect could flatten pleasure in people without depression who take the drugs.
- The brain's dopamine reward system is the proposed link — GLP-1 receptors may dial down signals that make food, and possibly other things, feel good.
- Researchers say the theory still holds even as early data looks cautiously positive for depressed patients.
