Summary

Story summary

Professor Takuya Takahashi of Yokohama City University leads a study on Long COVID cognition.
Using [11C]K-2 AMPAR PET, researchers compared AMPAR density in 30 patients and 80 controls.
They report a significant rise in AMPAR density in patients, correlating with symptom severity.
The imaging yields 100% sensitivity and 91.2% specificity; AMPAR antagonists are a potential therapy, pending trials.
