The researchers from NHS Lothian and Edinburgh University are recruiting adults WITH a diagnosis of bipolar disorder and adults WITHOUT bipolar disorder (control subjects).
The changing levels of light across the day and night affect many of our bodily processes – from our energy and hunger levels to our body temperature, mood, and feelings of sleepiness. These daily cycles are called circadian rhythms. The aim of the study is to find out why some people with bipolar disorder experience disrupted circadian rhythms.
If you are interested, you will be required to attend six study visits between the Royal Infirmary of Edinburgh and the University of Edinburgh.
The study involves:
Baseline visit: 90-minute appointment to answer questions about your day-to-day activities and sleep.
Part A: Two consecutive overnight stays at the Clinical Research Facility to measure hormone response to a night-time light experiment.
Part B: Two 2-hour appointments to test colour perception and responses to visual stimuli.
Part C: Three 40-minute appointments to image your eyes, spread out over an 18 month period
You will be reimbursed for your time and travel expenses if you take part.
