Brief summary
The purpose of the DISCOVER study is to pilot acceptable approaches to people with covert cerebrovascular disease (CCD) and their follow-up. This is the first step in designing efficient randomised trials of treatments to reduce the risk of stroke or dementia in people with CCD.
Detailed description
DISCOVER is a prospective cohort involving individuals with covert cerebrovascular disease (CCD) in NHS Lothian. Participants will be recruited through electronic health records and clinician collaborators. Participants will be monitored at 3 and 6 months and where possible 12 months to assess cognitive, functional, and vascular event outcomes.
Interventions
We will collect information about prior neurological symptoms, including prior symptoms suggestive of TIA or stroke, cognitive or motor symptoms, blood pressure and other known vascular risk factors, medicines, frailty, functional status, education, and employment status We will collect a baseline validated function and cognitive score, and take a sample of speech. Speech will be measured at assessment, in collaboration with the NeuroCARE Clinical and Digital Measures Module (22/SS/0010 IRAS No. 310885).

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Functional scores | At 3, 6 and 12 months following enrolment | The investigators will measure day-to-day function with the Bristol Activities of Daily Living Scale, which is a 20-item assessment of daily living abilities for dementia. Each activity has 5 statement options (a - e) which refer to a different level of ability. |
| Cognitive scores | At 3, 6 and 12 months following enrolment | The investigators will measure concerns or anxiety about covert cerebrovascular disease using the Montreal Cognitive Assessment. It is a 10-minute test that assesses seven areas of cognition for a total possible score of 30 points. A score of 25 or less is indicative of cognitive impairment. |
| Speech samples | At 3, 6 and 12 months following enrolment | Speech will be measured at assessment, in collaboration with the NeuroCARE Clinical and Digital Measures Module (22/SS/0010 IRAS No. 310885). |
| Vascular events | At 3, 6 and 12 months following enrolment | At each assessment the investigators will ask about dementia, mild cognitive impairment and stroke symptoms. |
