Overview
- The DZNE–Harvard analysis estimates about 36% of dementia cases in Germany are attributable to modifiable factors, based on the 2023 German Age Survey.
- Using the Lancet Commission framework, the study could assess 12 of 14 established risk factors with nationally representative data.
- About 1.8 million people currently live with dementia in Germany, with projections reaching roughly 2.7 million by 2050 if prevention does not improve.
- Modeling suggests a 15% reduction in risk factors could avert around 170,000 cases by 2050, rising to more than 330,000 with a 30% reduction.
- Top contributors identified for Germany are depression, hearing loss, low educational attainment, overweight, and diabetes, underscoring needs in care access, education, and health promotion.
