Sleep apnoea sub-study

Aug 16, 2014

Why are ASPREE participants wearing a monitor in their own bed overnight?


Sleep apnoea refers to breathing problems that may be experienced during sleep. It is a very common disorder that is usually associated with snoring and can often be so mild that most people are not aware they have it.

SNORE-ASA (SNORE-ASA: Study of Neurocognitive Outcomes, Radiological and Retinal Effects of Aspirin in Sleep Apnoea) is an ASPREE sub-study to help determine if sleep apnoea adversely affects concentration and memory in older adults and if aspirin can help slow down associated changes in small blood vessels in the brain.

What does participation involve?

SNORE-ASA sub-study participants wear a small sleep monitor overnight in their own bed and undertake two short thinking and memory exercises at the beginning of the ASPREE trial (prior to starting study medication), repeated at 1 and 3 year’s time.

Some participants also volunteer to have a MRI (magnetic resonance imaging) of the brain and retinal photographs (specialised photography of the back of the eye).

Newly randomised ASPREE participants living in Adelaide, Melbourne, Ballarat, Bendigo, Wodonga and Southern NSW are eligible to enrol in the SNORE-ASA sub-study.
