Trial Summary

What is the purpose of this trial?

This trial measures microglial activity in Alzheimer's patients and compares it to healthy older adults. It aims to understand why some people with brain changes typical of Alzheimer's develop dementia while others do not. Microglia are brain cells that help with immune responses, and their activity might be linked to Alzheimer's symptoms.
