AD, Alzheimer’s disease; MCI, mild cognitive impairment; MixD, mixed type dementia (=AD + SVD); SCI, subjective cognitive impairment; SVD, subcortical vascular dementia. AD = conversion from Global deterioration scale (GDS) 2 or 3 to GDS 4 + fulfillment of AD criteria. SVD = conversion from GDS 2 or 3 to GDS 4 + fulfillment of SVD criteria. MixD = conversion from GDS 2 or 3 to GDS 4 + fulfillment of MixD criteria. Dementia, other = conversion from GDS 2 or 3 to GDS 4 (after 2 years 4 nonultra descriptum (NUD) and 1 primary progressive aphasia (PPA), after 6 years 3 additional NUD. Stable MCI = first and current examination GDS 3. Stable SCI = first and current examination GDS 2. SCI–MCI = first examination GDS 2 and current examination GDS 3. MCI–SCI = first examination GDS 3 and current examination GDS 2. MCI–healthy = first examination GDS 3 and current examination GDS 1. Round skipped = current round skipped, next examination carried out. Missing follow-up: deceased. Somatic disease = not followed up due to somatic disease. Examination declined = further examination declined. No information = not followed up, no information available.
