Cerebral or brain infarction is a pathological process that restricts or blocks the supply of blood to the brain due to occlusion or narrowing of cerebral blood vessels. At present, computed tomography (CT) and magnetic resonance imaging (MRI) are commonly used to image cerebral infarction. Along with imaging, numerous non-invasive external brain monitoring tools are being developed that use a variety of technologies to act as sensors for neurological disorders, including stroke. This review briefly discussed the recent biomarkers for cerebral infarction and its diagnostic system through different biosensors.
