P2–182: Anxiety and depressive symptoms as predictors of progression from mild cognitive impairment to Alzheimer's disease
2006
Occurrence of cognitive impairment and dementia in the community: a 9-year-long prospective study.
2008
Objective: To determine incidence rates of non-dementia cognitive impairment, to examine the impact of attrition due to death on the observed incidence estimates, and to compare the observed and corrected estimates of non-dementia cognitive impairment with dementia incidence rates. Methods: A total of 1,435 persons without dementia aged 75+ from the Kungsholmen Project were evaluated for occurrence of dementia over 9 years. A total of 1,070 cognitively unimpaired subjects were also followed using amnestic mild cognitive impairment (aMCI) and other cognitive impairment, no dementia (OCIND) definitions. To correct the observed incidence rates for attrition due to death, cognitive status for s…
The symptom of low mood in the prodromal stage of mild cognitive impairment and dementia: a cohort study of a community dwelling elderly population.
2011
Objective: To investigate the symptom of low mood as a predictor of mild cognitive impairment (MCI) and its progression to dementia, taking into account: i) MCI severity, ii) time of assessment, iii) interaction with other factors. Methods: 764 cognitively healthy elderly living in the community, from the Kungsholmen Project. Participants were assessed by direct interview to detect low mood. Subjects were then followed for six years to identify those who developed MCI. People with incident MCI were followed for a further three years to assess progression to dementia. Results: People with low mood at baseline had a 2.7-fold (95% Confidence Interval [CI] 1.9-3.7) increased risk of developing …
Rare coding variants in PLCG2, ABI3, and TREM2 implicate microglial-mediated innate immunity in Alzheimer's disease
2017
International audience; We identified rare coding variants associated with Alzheimer's disease in a three-stage case-control study of 85,133 subjects. In stage 1, we genotyped 34,174 samples using a whole-exome microarray. In stage 2, we tested associated variants (P < 1 × 10-4) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, we used an additional 14,997 samples to test the most significant stage 2 associations (P < 5 × 10-8) using imputed genotypes. We observed three new genome-wide significant nonsynonymous variants associated with Alzheimer's disease: a protective variant in PLCG2 (rs72824905: p.Pro522Arg, P = 5.38 × 10-10, odds ratio (OR) = 0.68…
Heterogeneity in Risk Factors for Cognitive Impairment, No Dementia: Population-Based Longitudinal Study From the Kungsholmen Project
2006
OBJECTIVES: The objectives of this study were to investigate the relation of vascular, neuropsychiatric, social, and frailty-related factors with "Cognitive impairment, no dementia" (CIND) and to verify their effect independently of future progression to Alzheimer disease (AD). METHODS: Seven hundred eighteen subjects aged 75+ years who attended baseline, 3- and 6-year follow-up examinations of the Kungsholmen Project, a Swedish prospective cohort study, were studied. CIND was defined according to the performance on the Mini-Mental State Examination. Potential risk factors were collected at baseline and clustered according to four research hypotheses (frailty, vascular, neuropsychiatric, an…
