Recruiting · Not specified · Washington University School of Medicine · registry updated 2026-06-09
Inclusion and exclusion lines below are quoted from ClinicalTrials.gov. No match score is shown, because a score needs a person's age, biomarkers, and treatment dates. Confirm the record with the study team.
This study involves a brain positron emission tomography (PET) scan with a new, investigational radioactive tracer called \[11C\]-CS1P1 to identify inflammation in the brain by testing with healthy older adults and with cognitively impaired older adults.
Inclusion
- Male or female, any race;
- Age ≥ 50 years;
- Capable of providing written informed consent OR having a legally authorized representative (LAR) to provide informed consent for volunteering to undergo research procedure;
- Additional inclusion for ADRD group: clinical diagnosis of mild cognitive impairment or early dementia due to ADRD, OR biomarker diagnosis of Alzheimer's disease, with or without symptoms.
Exclusion
- Hypersensitivity to \[11C\]-CS1P1 or any of its excipients;
- Contraindications to PET, CT, or MRI (e.g. certain incompatible electronic medical devices, inability to lie still for extended periods) that make it potentially unsafe for the individual to participate;
- Severe claustrophobia;
- Women who are currently pregnant or breast-feeding;
- Currently undergoing radiation therapy;
- Any condition that, in the opinion of the Sponsor-Investigator or designee could increase risk to the participant, limit the participant's ability to tolerate the research procedures or interfere with collection of the data (e.g., renal or liver failure, advanced cancer);
