  1. Epidemiology of Dementia: the MoVIES Project • Alzheimer’s Disease Patient Registry (ADPR ), University of Pittsburgh • Initially funded by NIA 1987-1989 under cooperative agreement, U01 AG06782: Population-based Dementia Registry: • Subsequently funded by NIA 1989-2002 as project grant R01, AG07562, Epidemiology of Dementia: A Prospective Community Study. • Locally called “Monongahela Valley Independent Elders Survey” (MoVIES). Home

  2. MoVIES Project • Site: mid- Monongahela Valley in Washington and Westmoreland counties, Southwestern Pennsylvania; • 23 communities served by the 23 Mon Valley communities served by the Mon Valley Community Health Center, Monessen, PA. • Rural area with small towns, former home to coal mines and steel mills until the 1970s. Home

  3. MoVIES Cohort • Random sample, N=1422 1:13 age-stratified (65-74, 75+ years) random sample drawn from Voter Registration lists for the selected communities. • Volunteer sample, N=259 drawn from same area, meeting same entry criteria. Home

  4. MoVIES Entry Criteria • Age 65+ at time of recruitment; • Mon Valley resident; • Not in nursing home at time of recruitment; • Fluent in English; • At least Grade 6 education. Home

  5. MoVIES Cohort Characteristics • Total sample size of original cohort: • N=1681 (random plus volunteer) • Age: Mean (SD) = 72.6 (5.7) yrs (baseline) • Sex ratio: F:M=55.5 : 45 • Education: % < high school graduate: 43.3% Home

  6. MoVIES:Overview • Sample recruited 1987-1989 as part of ADPR; prevalent cases identified. • Began prospective followup in 1989; • Subjects re-assessed approximately every two years; incident cases identified. • Followup completed in 2002. Home

  8. MoVIES:Study procedures • At each wave: • All consenting survivors: cognitive screening and risk factor assessment. • Screening identifies those who are • (a) cognitively “impaired;” • (b) cognitively “declined.” • Impaired and declined subjects undergo clinical diagnostic evaluation for dementia. Home

  9. MoVIES Screening Criteria (1) Cognitive impairment: Actual scores, at any given time, at or below the 10th %ile of the sample on: • MMSE and/or • At least one memory test and one other test. Home

  10. MoVIES Screening Criteria (2) Cognitive Decline: Decline over time in scores • To “impaired” levels, and/or • By amounts greater than or equal to that experienced by 95 % of the cohort on • MMSEand/or • At least two other tests. Home

  11. MoVIES Clinical Evaluation (1) • In-home evaluation; • History and general physical exam; • Detailed neurological exam; • Brief mental status exam; • Psychiatric exam; • Blood: chemistry/hematology/serology; Home

  12. MoVIES Clinical Evaluation (2) • Based on Pittsburgh ADRC/CERAD assessment protocols, modified for field use; • DSM-III-R criteria for dementia; • CDR rating for stage/severity; • NINCDS-ADRDA criteria for Probable and Possible AD. Home
