Trial-Ready Cohort for the Prevention of Alzheimer's Dementia (TRC-PAD)

Start: June 4, 2019
End: April 30, 2023
Enrollment: 2000

What Is This Study About?

The Trial-Ready Cohort for the Prevention of Alzheimer's Dementia (TRC-PAD) is an observational study designed to create a group of cognitively healthy volunteers willing to participate in clinical trials aimed at discovering treatments that will reduce the risk of developing Alzheimer's dementia. TRC-PAD will help researchers enroll participants into these trials quickly. To join the TRC-PAD study, individuals must first complete an Alzheimer Prevention Trials (APT) Webstudy online questionnaire and memory tests. If selected, participants will make an in-person visit to a study site, where they will complete several assessments to see if they qualify to join the cohort. These assessments include a positron emission tomography (PET) brain scan, cerebrospinal fluid collection, tests of memory and thinking, questionnaires about daily functioning, mood and behavior, genetic testing, and routine blood and urine tests. Individuals who enroll in TRC-PAD will come back to the clinic every six months for brief follow-up visits, with questionnaires and testing, until they qualify for a clinical trial.
