Abstract
Introduction: This study investigated the association between modifiable factors and symptom progression in dementia over up to 8 years.
Methods: Multilevel growth curve models assessed the role of modifiable risk factors (low education, hearing impairment and its treatment, depression, physical inactivity, diabetes and its treatment, smoking, hypertension and its treatment, obesity, alcohol consumption, social isolation, and visual impairment) on cognitive and functional trajectories in 353 people with dementia.
Results: Higher education was associated with higher initial cognitive status but faster decline. Antidiabetic medication was associated with slower cognitive decline, whereas depression and visual impairment were linked to low baseline functioning and faster cognitive decline.
Discussion: Several modifiable risk factors influenced symptom progression. Education initially had a protective effect, whereas depressive symptoms were linked to worse symptom progression. Treatment of comorbidities (diabetes, visual impairment) could have a positive impact on dementia symptoms. Modifiable risk factors are promising targets for tertiary prevention.
Highlights: Modifiable risk factors were associated with symptom progression in dementia over up to 8 years.More education was associated with higher initial cognitive status but faster decline.Depressive symptoms were linked to less favorable symptom progression.Treatment of comorbidities (diabetes, visual impairment) may positively impact the course of symptoms.Modifiable risk factors are promising targets for tertiary prevention.
期刊介绍：
Alzheimer''s & Dementia: Diagnosis, Assessment & Disease Monitoring (DADM) is an open access, peer-reviewed, journal from the Alzheimer''s Association® that will publish new research that reports the discovery, development and validation of instruments, technologies, algorithms, and innovative processes. Papers will cover a range of topics interested in the early and accurate detection of individuals with memory complaints and/or among asymptomatic individuals at elevated risk for various forms of memory disorders. The expectation for published papers will be to translate fundamental knowledge about the neurobiology of the disease into practical reports that describe both the conceptual and methodological aspects of the submitted scientific inquiry. Published topics will explore the development of biomarkers, surrogate markers, and conceptual/methodological challenges. Publication priority will be given to papers that 1) describe putative surrogate markers that accurately track disease progression, 2) biomarkers that fulfill international regulatory requirements, 3) reports from large, well-characterized population-based cohorts that comprise the heterogeneity and diversity of asymptomatic individuals and 4) algorithmic development that considers multi-marker arrays (e.g., integrated-omics, genetics, biofluids, imaging, etc.) and advanced computational analytics and technologies.
