3/9/2026

Summary

Story summary

The study, published March 5, 2026, in Molecular Psychiatry, shows ketamine alters AMPAR distribution in treatment-resistant depression and correlates with improved reward-related brain function.
Takuya Takahashi of Yokohama City University led the study using a novel PET imaging method to observe AMPAR density.
The results indicate AMPAR dynamics may predict treatment response, enabling personalized depression therapies.
Limitations include a small sample size and focus on a Japanese population.
