Brief Summary
In adult patients presenting to emergency departments within 24 hours of symptom onset with suspected acute stroke, we aim:
- 1.to identify early brain- and pathology-specific circulating, whole blood, plasma and serum panorOmic biomarkers that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis.
- 2.to identify early brain- and pathology-specific, panorOmic biomarkers in saliva that enable early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis.
- 3.to derive biomarker platforms of models for early acute stroke detection, diagnosis, dynamics, differentiation, monitoring, prediction and prognosis
- 4.to validate these models in independent and external datasets

Outcome Measures
Primary Outcomes (1)
Differentiation of stroke from non-stroke in patients with suspected stroke
Stroke is defined as either a) the presence of intracerebral haemorrhage with imaging; or b) intracerebral ischaemia with imaging; or c) clinical features of stroke in the absence of positive imaging persisting after 24 hours (cryptogenic stroke). Cryptogenic stroke is defined according to TOAST as stroke not caused by large artery atherosclerosis, cardioembolism, small vessel occlusion and stroke of other aetiology. Non-stroke includes TIA and stroke mimics. TIA is defined as the resolution of stroke-like symptoms within 24 hours of onset and the absence of acute cerebral abnormalities on CT/MRI. Stroke mimics are defined as diseases caused by neurologic symptoms that resemble a stroke. For example, seizure, complex migraines, demyelinating disease, meningitis, glucose level variations and metabolic disorders (hypoglycemia), tumors, non-cerebrovascular diseases such as epilepsy, and dementia.
Up to 24 hours

Biospecimen
Liquid biopsy samples will be taken at three time intervals between stroke onset (Time 0) and 36 hours later i.e. i) in the ED at 0+x hours; ii) at 18±6 hours, and iii) 30±6 hours. Liquid biopsy for retention: • Whole Blood samples, Red blood cell effluent, Plasma, Serum, White cell pellet, Saliva (for genomic, epigenomic, transcriptomic and proteomic studies). Biomarkers under investigation: • DNA, RNA, Proteomics, Metabolomics, Metabolomics,Lipidomics gene expression in peripheral blood and saliva.
