Investigating smell and sight changes as early signs of Alzheimer's disease

Olfactory and Visual Dysfunction as Potential Predictors of Preclinical Alzheimer's Disease

NIH-funded research San Diego State University · NIH-10534224

This study is looking at how problems with smelling and seeing might be early signs of Alzheimer's disease in people who are at risk, like those with certain genetic factors or mild memory issues, to see if these changes can help spot the disease before it fully develops.

What this research studies

This research explores how changes in the ability to identify odors and visual function may indicate early signs of Alzheimer's disease (AD). It focuses on individuals at risk for AD, such as those with the ApoE e4 allele or mild cognitive impairment (MCI). By using advanced testing methods beyond simple odor identification, the study aims to determine if these sensory impairments can serve as reliable indicators of preclinical AD. The research will also examine the relationship between these sensory changes and biomarkers found in cerebrospinal fluid and brain imaging.

Who could benefit from this research

Good fit: Ideal candidates for this research include individuals with a family history of Alzheimer's disease, those carrying the ApoE e4 allele, or individuals diagnosed with mild cognitive impairment.

Not a fit: Patients who do not have any risk factors for Alzheimer's disease or those with advanced stages of dementia may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to earlier detection of Alzheimer's disease, allowing for timely interventions and better management of the condition.

How similar studies have performed: Previous research has shown that sensory impairments can be indicative of Alzheimer's disease, but this study aims to refine and validate these findings through a novel multimodal approach.
