Brief Summary
The Bio-Repository of DNA in Stroke (BRAINS) recruits all subtypes of stroke as well as controls from two different continents, Europe and Asia. Subjects recruited from the United Kingdom (UK) will include stroke patients of European ancestry as well as British South Asians. Stroke subjects from South Asia will be recruited from India and Sri Lanka. Subjects are also recruited in Qatar. South Asian cases will also have control subjects recruited.

Eligibility Criteria
Patients and spouse or age-matched controls will be screened at the participating clinical centres in the United Kingdom (London, Luton, Birmingham, Leeds, Leicester, Airedale, Bradford, Wolverhampton and Blackburn), India (New Delhi and Kerala), Qatar and Sri Lanka (Colombo). Detailed phenotype data will be collected in a specially designed BRAINS data collection form. Stroke will be confirmed with computed tomography or magnetic resonance imaging and subtyped according to the Trial of ORG10172 in Acute Stroke Treatment (TOAST) classification. Baseline clinical and demographic data will also be collected. Blood samples will be collected in EDTA coated plastic serological tubes from all consenting patients and controls by means of a single venepuncture and DNA extracted from peripheral lymphocytes using standard procedure and stored at -20°C. Following genotyping the genetic data will be merged with phenotype data (environmental risk factors, stroke sub-type) for analysis.
You may qualify if:
- Patients should be aged \> 18 years at the time of enrolment.
- Diagnosis of haemorrhagic or ischemic stroke using World Health Organization guidelines confirmed by clinical examination and imaging (CT or MRI).
- All patients with cerebral arteriovascular malformations and aneurysms.
- South Asian or Caucasian ethnic backgrounds.
- Patient or relative written informed consent.
You may not qualify if:
- Unable to provide consent themselves or through surrogate.
- Stroke not defined on CT or MRI.
- Controls
- Patients should be aged \> 18 years at the time of enrolment.
- No previous history of stroke.
- able to provide written consent.
