Summary

This study looks at how mood disorders and insomnia interact by monitoring heart and brain activity. Researchers will measure signals like heart rate variability and brain waves in 200 people, including healthy volunteers and those with mood or sleep issues. The goal is to understand the biological links between emotional health and sleep, which could lead to better diagnosis or treatment approaches.

What this could lead to

What could go wrong
