Outcome Measures

Primary Outcomes (1)

  • Inter-rater Reliability

    Measure of agreement among five readers using a binary read method (amyloid positive/negative) calculated using Fleiss' kappa. All scans were read in a blinded fashion without access to clinical information.

    Scan acquired 50-60 min post-injection

Secondary Outcomes (2)

  • Sensitivity of Florbetapir-PET to Detect Moderate to Frequent Beta-amyloid Neuritic Plaques (Probable/Definite Alzheimer's Disease)

    at autopsy, within 2 years of scan

  • Specificity of Florbetapir-PET to Detect no or Sparse Beta-amyloid Neuritic Plaques (Probable/Definite Alzheimer's Disease)

    at autopsy, within 2 years of scan

Other Outcomes (1)

  • Median Sensitivity and Specificity vs. CERAD Diagnosis

    Baseline scan

Interventions

No study drug will be administered in this study - scans previously acquired in in Study A05(NCT00702143) and A07(NCT00857415) will be read

Also known as: 18F-AV-45, Amyvid, florbetapir

Eligibility for subjects scans to be used in this study is determined by subject's eligibility/enrollment in Study A05 (NCT00702143) or A07 (NCT00857415). Alzheimer's disease (AD) group key eligibility criteria (from Study A05\[NCT00702143\]): * Male or female at least 50 years of age * Have probable AD per National Institute of Neurological and Communication Disorders and Stroke (NINCDS) criteria * Mini mental state exam (MMSE) score between 10 and 24 inclusive Mild cognitive impairment group key eligibility criteria (from Study A05\[NCT00702143): * Male or female at least 50 years of age * Complaints of memory or cognitive decline corroborated by an informant * Clinical dementia rating of 0.5 * No obvious cause for cognitive impairment (eg, head trauma or stroke) * Cognitive impairment onset within the past year * MMSE score greater than 24 Cognitively normal volunteer group key eligibility criteria (from Study A05\[NCT00702143\]): * Male or female at least 50 years of age * MMSE score greater than or equal to 29 and cognitively normal by informant report and psychometric test battery at screening Autopsy cohort key eligibility criteria (from Study A07\[NCT00857415\]): * Male or female 18 years or older * Projected life expectancy of less than 6 months * Consent to brain donation
