Who could benefit from this research

Could help

Adults aged 40–80 with Alzheimer’s disease, FTLD, or who are controls, from diverse settings in the ReDLat network.

Less likely to help

Individuals without circadian disturbance or those outside the study populations may not directly benefit.

What this research studies

This project will analyze data from a large dementia research database to see how circadian disturbances relate to Alzheimer’s disease and frontotemporal lobar degeneration. Researchers will look at information on sleep, activity, cognition, and other factors to identify patterns that might signal risk or progression. The team uses a multi-partner dataset from Latin America to study adults aged 40–80 and will examine how timing of daily activities intersects with dementia characteristics.

Why it matters

Potential benefit: If successful, findings could help people with dementia and those at risk understand how sleep and daily rhythms affect symptoms and progression.

How similar studies have gone: Previous research links disrupted circadian rhythms to worse health outcomes, but this project aims to clarify its role in specific dementia types.
