Understanding how sensory changes and aging in midlife relate to Alzheimer's and dementia

The Beaver Dam Offspring Study Neurocognitive Aging Study (BOSS-NCAS)-A Study on the Role of Accelerated Aging and Midlife Sensory Decline for Early Alzheimer’s Disease and Dementia in Later Life

NIH-funded research University of Wisconsin-Madison · NIH-11122200

This project explores how changes in hearing, vision, and smell, along with signs of aging in middle age, might predict the risk of Alzheimer's disease and related dementias later in life.

What this research studies

This project builds on a long-term health observation called the Beaver Dam Offspring Study (BOSS). We are looking at how changes in your senses—like hearing, vision, and smell—along with certain signs of aging in midlife, might be connected to developing Alzheimer's disease and related dementias later on. Participants will undergo detailed examinations, including hearing and eye tests, smell identification, and a range of cognitive tests. We will also review medical records, speak with caregivers, and analyze blood samples for markers related to Alzheimer's. Our goal is to understand these connections better to help identify people at risk earlier.

Who could benefit from this research

Good fit: Ideal candidates are previous participants of the Beaver Dam Offspring Study (BOSS) who were between 21 and 84 years old at the baseline examination.

Not a fit: Patients who are not part of the existing Beaver Dam Offspring Study cohort would not directly benefit from participation in this specific follow-up.

Why it matters

Potential benefit: If successful, this work could help identify early risk factors for Alzheimer's disease and related dementias, potentially leading to earlier detection and prevention strategies.

How similar studies have performed: This study builds upon an established longitudinal cohort, extending previous findings on aging and health, and incorporates novel biomarkers.
