Q1a. Please indicate below if your cohort includes or expects to include, incidence of the following conditions?
Alzheimer's disease and other dementias|Neurodegenerative disease in general
Q1b. When are studies on the above condition(s) expected to become possible?
Q2a. In a single sentence what is the stated aim of the cohort?
To increase our understanding of the aging process and to identify preventive strategies that can lead to improved health and care of the elderly. I carry out several studies within SNAC-K: e.g., (1)Vascular risk factors and mechanisms of cognitive decline in aging; (2)Dementia trends over time; (3)Functional disability (might be due to brain degeneration) trend and determinants over time
Q2b. What distinguishes this cohort from other population cohorts?
My research involces 2 distinguishes in this cohort: (1)epidemiological, clinical, and brain imaging data are integrated; (2)long-term follow-up that fits the need of studying health trends.
