Summary

This study is analyzing blood samples from 1,799 people with Alzheimer's, dementia, depression, bipolar disorder, schizophrenia, or Parkinson's disease.

Participants also undergo thinking and memory tests, and some have brain scans. The goal is to improve understanding, not to test a new treatment.
