AlzRisk Cohort Detail

Cohort: German Study on Ageing, Cognition and Dementia in Primary Care Patients
Risk Factors:

Introduction to the Cohort
This prospective study was conducted in six centres (Bonn, Düsseldorf, Hamburg, Leipzig, Mannheim and Munich) representing an urban area of cities with a total population ranging between about 300,000 (Mannheim) and almost 1.8 million (Hamburg). Inclusion criteria for GP patients were an age of 75 years and over, at least one contact with the GP within the last 12 months, and the absence of dementia in the GP’s view.

Of the 3,327 patients interviewed at baseline, 84.8% (n = 2,820) could be personally interviewed 1.5 years later and 73.9% (n = 2,460) 3 years later. For the vast majority of subjects who could not be personally interviewed, systematic assessments, focusing particularly on dementia, were obtained from GPs, relatives or caregivers.

Ethnicity Breakdown
Participants were all residents of German cities. No other information on ethnicity or race has been reported.
