Study design:

Cross-sectional 

研究目的:

1)探索重度阿尔兹海默病患者嗅觉识别能力与认知功能变化的关联性,分析特定气味嗅觉障碍是否可作为认知衰退的指标。 2)建立嗅觉-认知-MR海马的多维关系模型:研究嗅觉识别能力、认知功能变化与MR海马的协同关联,揭示嗅觉功能在 AD 病理进程中的潜在作用。  

Objectives of Study:

1) To investigate the association between olfactory identification ability and cognitive function changes in patients with severe Alzheimer's disease (AD), and to analyze whether specific odor identification impairment may serve as an indicator of cognitive decline. 2) To establish a multidimensional relationship model integrating olfactory-cognitive-MR hippocampal measures: by examining the synergistic associations among olfactory identification ability, cognitive function changes, and magnetic resonance (MR) hippocampal parameters, this study aims to untangle the potential role of olfactory dysfunction in the pathological progression of AD.
