Noradrenaline, sleep, and thinking in older adults with insomnia
Noradrenergic Dysregulation, Sleep and Cognition in Older Adults with Insomnia
This project will see whether lower noradrenaline activity is linked to poorer sleep and thinking in older adults with insomnia.

What this research studies
You would take part if you are an older adult with insomnia and agree to physiological monitoring and cognitive testing. The team will measure noradrenergic activity over a 24-hour period and record brain sleep signals such as slow oscillations and wake after sleep onset. You will also complete memory and thinking tests so researchers can compare sleep and noradrenaline patterns with cognitive performance. The goal is to understand whether lower daytime noradrenaline relates to worse sleep quality and thinking skills.
Who could benefit from this research
Good fit: Older adults with chronic insomnia who are concerned about memory or thinking changes would be the best fit for this work.
Not a fit: People without insomnia, those with advanced dementia, or those whose sleep issues are caused by other diagnosed sleep disorders may not directly benefit from this project.
Why it matters
Potential benefit: If successful, this work could identify biological links between insomnia and thinking problems and point to new targets to protect sleep and cognition in older adults.
How similar studies have performed: Previous studies have connected noradrenergic activity with sleep and cognition, but applying continuous 24-hour measurements in older adults with insomnia is a novel approach.
