Ischemic stroke is now widely recognized as a disease with a strong inflammatory profile. Cerebral vascular damage is both preceded and followed by a chain of molecular events involving immune cells and inflammatory markers, irrespective of the etiology of the ischemic injury. Over time, an increasingly comprehensive understanding of these markers has led to a better insight into the mechanisms behind the vascular event and recovery following ischemic stroke. However, to date, there are still no available circulating or tissue biomarkers for early diagnosis or prognostic stratification, making ischemic stroke diagnosis contingent on clinical and instrumental investigations. However, neurological and internal medicine research is progressing in identifying markers that could potentially take on this role. This manuscript, therefore, aims to review the most recent and innovative results of medical advances, summarising the current state of the art and future perspectives. If ischaemic stroke is an inflammatory disease, it is also true that it is not just a singular condition, but a group of entities with their own neuroinflammatory features. Thus, given that, in ischemic cerebral vascular damage, “time is brain,” tracking increasingly accurate markers in the diagnosis of ischemic stroke is a valuable tool that will potentially enable earlier recognition of this disease and, hopefully, make it less disabling and more widely treated.
