Summary

This observational study looks at whether people with shingles (herpes zoster) have a higher risk of vascular dementia—memory loss from reduced blood flow to the brain. Researchers will analyze tiny particles called exosomes in blood samples from 375 participants over 12 months. No treatment is given; the goal is to understand the connection.
