Determining the functionality of this brain region may help us diagnose AD more accurately, thus allowing earlier treatment.", 'detailedDescription': "The posterior cingulate is a key brain region suggested by recent studies to be affected in people at risk for Alzheimer's Disease (AD). Because the PC is affected very early in the course of AD and the region may have reduced function even prior to the onset of symptoms, further understanding of its functional role and its relationship to other brain regions may be helpful in detecting AD earlier and in monitoring disease progression and treatment. This project examines the role of the PC and its connections to other brain regions using functional magnetic resonance imaging (fMRI), a technique that allows us to examine the brain at work during tests of memory and decision-making. The main goal is to see if functional connections between brain regions are modulated by risk for AD."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '65 Years', 'minimumAge': '55 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'People who are enrolled in the Wisconsin Registry for AD Prevention (WRAP), recruited from Memory clinics and the community.', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Cognitively healthy\n* (Controls Only) Parents survived past age 70 and did/do not have memory problems.\n\nExclusion Criteria:\n\n* Claustrophobia\n* Metallic or electronic implants'}, 'identificationModule': {'nctId': 'NCT00478166', 'acronym': 'PC', 'briefTitle': "Posterior Cingulate Function in Persons With Risk Factors for Alzheimer's Disease", 'organization': {'class': 'OTHER', 'fullName': 'University of Wisconsin, Madison'}, 'officialTitle': "Posterior Cingulate Function in Persons With Risk Factors for Alzheimer's Disease", 'orgStudyIdInfo': {'id': '2004-174'}}, 'contactsLocationsModule': {'locations': [{'zip': '53792', 'city': 'Madison', 'state': 'Wisconsin', 'country': 'United States', 'facility': 'University of Wisconsin - Wisconsin Comprehensive Memory Program', 'geoPoint': {'lat': 43.07305, 'lon': -89.40123}}], 'overallOfficials': [{'name': 'Sterling C Johnson, PhD', 'role': 'PRINCIPAL_INVESTIGATOR', 'affiliation': 'University of Wisconsin/VA GRECC'}]}, 'sponsorCollaboratorsModule': {'leadSponsor': {'name': 'University of Wisconsin, Madison', 'class': 'OTHER'}, 'collaborators': [{'name': 'VA Office of Research and Development', 'class': 'FED'}], 'responsibleParty': {'type': 'SPONSOR'}}}}
