ADRC Clinical Cohort (Alzheimer's Disease)

Duke/UNC Alzheimer's Disease Center Clinical Cohort

About This Trial

The purpose of the study is to establish a clinical cohort for the Duke/UNC Alzheimer's Disease Research Center (ADRC). The cohort will be composed of subjects ages 25 to 44 at enrollment with normal cognition and subjects ages 45 to 80 at enrollment with normal cognition, mild cognitive impairment, or a dementia diagnosis. Initial data including demographics, medical and family history, physical exam, and neuropsychological testing will be obtained. Participants will be asked to contribute a blood sample, a urine sample, a cerebrospinal fluid sample, and undergo a MRI scan. The cohort ages 45 to 80 will be seen yearly until death to evaluate medical status, undergo neuropsychological testing and possibly collect additional samples or undergo additional imaging. All data will be de-identified and stored by the ADRC. The purpose of this study is to examine normal cognition, mild cognitive impairment and Alzheimer's disease and related dementias (ADRD) as people get older. The investigators also hope to be able to assess risk factor information of the role of genes and environmental exposures (for example health conditions, diet, and medications) in Alzheimer's disease and related disorders (ADRD) and other conditions of aging. The biological samples collected in the study will create a repository. A repository is a collection of blood and tissue samples from people with certain diseases and conditions. For the purpose of this research, the investigators hope to help researchers learn more about Alzheimer's disease and related disorders and other conditions of aging.

Who May Be Eligible (Plain English)

Who May Qualify: - Each subject must be ≥ 25 to ≤ 80 years of age. - Each subject must be able to read at a 6th grade level, as determined by the investigator, and must have a history of academic achievement and/or employment sufficient to exclude intellectual disability. - Each subject (or legal representative) must sign the willing to sign a consent form form after the scope and nature of the investigation have been explained to them, and before screening assessments. Some consent may be obtained via phone script and REDCap eConsent. - Each participant must be willing to have an MRI and a lumbar puncture, or alternately (to the lumbar puncture) a series of PET scans. - Each participant ages 45 to 80 must have a study partner who agrees to participate in the study and who is able to read at a 6th grade level, as determined by the investigator, and must have a history of academic achievement and/or employment sufficient to exclude intellectual disability. Who Should NOT Join This Trial: - Evidence of a clinically relevant or unstable neurological disorder including history of multiple head injuries, stroke or other CNS conditions (MS, Parkinson's disease, etc.) - Evidence of a clinically relevant or unstable psychiatric disorder. - History of alcoholism or drug dependency/abuse within the last 2 years before enrollment. - GAD-7 score \>9 and/or PHQ-8 score \>9 - An ongoing uncontrolled, clinically significant medical condition such that, in the judgment of the investigator, a subject's participation in the trial would pose a significant medical risk to the subject. - Contraindication or intolerance to 3T MRI investigations, including implanted devices ...See full criteria on ClinicalTrials.gov Always talk to your doctor about whether this trial is right for you.
