Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals aged 60 to 85 with a prodromal stage of Alzheimer's disease or cognitively healthy seniors matched by age and sex.

Probably not a fit

Patients outside the age range of 18 to 85 or those not fluent in French may not benefit from this study.

What this trial studies

This study investigates how cognitive deficits associated with aging and Alzheimer's disease relate to slow wave activity measured through EEG during both sleep and wakefulness. The researchers aim to identify slow waves as a potential biomarker for sleep disturbances and daytime vigilance issues that affect memory processes. By examining these relationships, the study seeks to understand how alterations in sleep and attention impact memory encoding, consolidation, and retrieval in older adults. Participants will undergo video polysomnography and attention tasks to gather data on their cognitive and sleep patterns.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and interventions for memory-related issues in aging and Alzheimer's patients.

How similar studies have gone: While the approach of linking EEG slow waves to cognitive decline is innovative, previous studies have explored related concepts, indicating potential for success.
