The ARIC MRI Study

Status Completed

Clinical Trial Summary

To perform a follow-up study of cerebrovascular disease in the Atherosclerosis Risk in Communities (ARIC) magnetic resonance imaging subcohort.

Clinical Trial Description

BACKGROUND:

Although the clinical manifestations of cerebrovascular disease (CVD) typically appear acutely, the deleterious effects of CVD on brain structure and function likely begin in a presymptomatic fashion at a younger age than clinical strokes. In an effort to characterize the prevalence, risk factors, and cognitive correlates of subclinical CVD, the Atherosclerosis Risk in Communities (ARIC) Study funded by the National Heart, Lung, and Blood Institute performed cerebral magnetic resonance imaging (MRI) and cognitive assessments on a large, bi-racial sample of middle-aged and young-elderly adults. Results from the ARIC MRI baseline study revealed a remarkably high prevalence of subclinical CVD including silent cerebral infarctions, white matter hyperintensities, and brain atrophy. Moreover, these subclinical abnormalities were found to be associated with reduced cognitive functioning and with clinical CVD outcomes such as incident stroke. Surprisingly little is known about risk factors related to the incidence or progression of subclinical CVD or how progression of these markers may relate to clinical outcomes such as stroke or neurocognitive decline.

DESIGN NARRATIVE:

This is a follow-up study of the ARIC MRI cohort, with repeated semiquantitative MR imaging and cognitive assessments. The study will also take advantage of recent advances in MR imaging and obtain volumetric measurements of selected brain regions and expand upon the baseline cognitive assessment to further characterize neurocognitive functioning. The longitudinal design of the proposed study will fill salient gaps in current understanding of subclinical CVD. Moreover, conducting this study within ARIC takes advantage of ARIC's baseline MRI data, unique African American population, and extensive vascular risk factor data (including new genetic and biochemical factors as well as subclinical markers of both large and small vessel disease), making an efficient study to provide new insights into the incidence, progression, and outcomes associated with subclinical CVD. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
