Summary
Rapid diagnosis of stroke is crucial for effective treatment. This review highlights promising blood biomarkers and point-of-care technologies for faster, accurate stroke diagnosis and differentiation.
Area of Science:
- Neurology
- Biomarkers
- Medical Diagnostics
Background:
- Stroke is a major global cause of death and disability.
- Early and precise diagnosis is critical for effective acute stroke care, as treatment efficacy is time-dependent.
- Current diagnostic methods require optimization for speed and accuracy.
Purpose of the Study:
- To review key blood-protein biomarkers for stroke differential diagnosis.
- To identify biomarkers capable of distinguishing between ischemic and hemorrhagic stroke.
- To provide an overview of emerging point-of-care (POC) technologies for rapid stroke diagnostics.
Main Methods:
- Literature review of well-documented blood-protein biomarkers for stroke.
- Analysis of recent advancements in point-of-care biosensor technology.
- Discussion on integrating biomarker data with clinical and imaging parameters.
Main Results:
- Several blood-protein biomarkers show significant potential for clinical translation in stroke diagnosis.
- Point-of-care technologies are advancing for rapid, accessible stroke detection.
- Multi-dimensional algorithms integrating biomarkers, clinical data, and neuroimaging are emerging.
Conclusions:
- Blood biomarkers and POC technologies offer a promising avenue for improving acute stroke diagnosis.
- Personalized stroke care will benefit from integrating fluid-based biomarker profiling with other clinical data.
- Further development and validation are needed for widespread clinical adoption.

Ischemic Stroke l: Introduction
44
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.

Hemorrhagic Stroke l: Introduction
20
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...

Hemorrhagic Stroke ll: Pathophysiology
30
A hemorrhagic stroke develops when a cerebral blood vessel ruptures, allowing blood to escape into the surrounding brain tissue, as in intracerebral hemorrhage (ICH), or into the subarachnoid space, as in subarachnoid hemorrhage (SAH). Because the skull is a rigid compartment, the sudden presence of extravascular blood rapidly increases intracranial pressure and compresses adjacent neural structures, leading to immediate tissue injury and impaired cerebral perfusion.Mass Effect and Primary...
