Faster decline of very prodromal dementia with Lewy bodies when amyloid positive.
Introduction: The cognitive and neuroimaging evolution during dementia with Lewy bodies (DLB) from the prodromal phase (Pro-DLB; subjective cognitive impairment [SCI] to mild cognitive impairment [MCI]) according to amyloid beta (Aβ) status is poorly understood.
Methods: The decline of Lewy-Memento patients with SCI or MCI was compared according to Aβ status across four groups: Pro-DLB, prodromal Alzheimer's disease (Pro-AD), Pro-DLB+AD, and a group without prodromal DLB and AD (no symptoms [NS]). We observed the evolution of cognitive, functional, quality of life measures, brain volumetry, and metabolism on fluorodeoxyglucose positron emission tomography.
Results: In the Pro-DLB and Pro-DLB+AD groups, Aβ+ patients had more cognitive and functional decline than the Aβ- patients. In the Pro-AD and NS groups, Aβ+ patients had more functional decline. Aβ+ Pro-AD showed a greater volume decline of the brain (left insula).
Discussion: The presence of amyloid lesions worsens very prodromal DLB patients over time, both cognitively and functionally, but without increasing atrophy.
Highlights: Patients at a very prodromal stage, subjective cognitive impairment or mild cognitive impairment, had a clinical diagnosis of either prodromal Alzheimer's disease (Pro-AD), prodromal dementia with Lewy bodies (Pro-DLB), Pro-DLB+AD, or no diagnosis.Amyloid beta positive (Aβ+) patients had more functional decline, whatever the group.Aβ+ DLB patients (Pro-DLB and Pro-DLB+AD) had more global cognitive (Mini-Mental State Examination) decline.Aβ+ Pro-AD patients showed a greater volume decline of the left insula.
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.
