10,000 scots to help unlock Dementia's secrets
NCT ID NCT05892952
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
The IONA study is recruiting 10,000 people aged 50 and over living in Scotland to track their memory, thinking, lifestyle, and health over many years. Participants will provide information on risk factors like hearing loss and obesity, and some will give blood or spinal fluid samples for genetic and biomarker testing. The goal is to better understand how dementia develops and to identify groups who may have different disease patterns.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could help researchers build better models to predict who might develop dementia and identify factors that slow or speed up the disease.
- What could go wrong
- This is an observational study, not a treatment trial. It will take years to gather enough data, and the findings may not lead to any direct medical advances.

Who is studied
The IONA LCS is designed to be inclusive and from within this diverse population smaller sub-populations will be derived. Given the main objective of the programme, the study is open to people over the age of 50 who range from having no symptoms of neurodegenerative disease to those living with a dementia syndrome at the mild stage of illness. All participants will have the capacity to consent to the study at the baseline. Participants who develop moderate-to-severe dementia, and those who lose capacity to provide informed consent during the study, will remain in the study to ensure disease models can capture the full trajectories of these diseases. Recruitment strategies will be designed using the above five sources to ensure all people representative of the Scottish population (ensuring there is representation from different ages, sex, ethnicity, education, socioeconomic status) who are suitable for the IONA LCS are invited to participate.
