Plain English summary of protocol

Background and study aims
Transient ischemic attack (TIA), also known as a mini-stroke, is a common event during which people briefly experience stroke symptoms including loss of movement, sensation, speech and vision. There is a risk of permanent stroke during the next 90 days which can be reduced by urgent medical treatment. However, being certain of the diagnosis is challenging because other conditions can produce identical symptoms. The commonest condition which can produce the same symptoms is migraine, and people suffering migraine are not at high risk of stroke. Tests have a limited role in differentiation between TIA and migraine and uncertainty about the correct diagnosis can lead to missed opportunities to prevent stroke if TIA is not recognised, and overtreatment of people with migraine.

This research study aims to develop an assessment which will help clinicians predict the risk of stroke when reviewing patients presenting with symptoms which could be caused by both TIA and migraine.

Who can participate?
Adults (aged 40 years and over) who present with symptoms which could be caused by both TIA and migraine.

What does the study involve?
Clinical information will be collected from people who agree to take part. This will include presenting symptoms, investigations and treatments, and what happens to health over the next 90 days. This information will be analysed mathematically to develop the stroke risk assessment.

What are the possible benefits and risks of participating?
There are no direct benefits to individuals who take part in the study, but it is hoped that care for future patients will be improved as a result of this research.

Where is the study run from?
Newcastle University (UK)

When is the study starting and how long is it expected to run for?
August 2024 to July 2027

Who is funding the study?
NIHR Research for Patient Benefit Programme (UK)

Study objectivesThe aim of the study is to define the risk of stroke for people with migrainous symptoms reviewed as suspected transient ischemic attack (TIA) and develop a stroke risk assessment tool that could promote standardisation of care.
Ethics approval(s)

Approved 11/09/2024, London - Stanmore Research Ethics Committee (2nd Floor, 2 Redman Place, Stratford, London, E20 1JQ, United Kingdom; +44 207 1048258; stanmore.rec@hra.nhs.uk), ref: 24/PR/0977

Health condition(s) or problem(s) studiedSuspected TIA or migraine.
InterventionThis research project is an observational cohort study involving patients with symptoms which could be caused by both TIA and migraine. At study entry, data will be collected about presenting symptoms, investigations and treatments. After 90 days, data will be collected about further episodes of migraine or TIA, and whether a stroke has occurred.
Intervention typeOther
Primary outcome measure(s)

Stroke occurrence determined from medical record information and independent adjudication at 90 days

Key secondary outcome measure(s)

Clinical features, investigations and treatments determined from medical record information at baseline
