The strokes have been a challenge for doctors and have become one of the main causes of death and disability in the world, even with trained staff, imaging technologies, and appropriate hospitals, since clinical suspicion in the early stages of the event is difficult, as is the determination of severity. Consequently, possible biomarkers have been investigated in the peripheral blood of patients with a cerebrovascular accident, but none have found a place in clinical practice due to the lack of specificity and sensitivity, easy access, cost-effectiveness ratio, or protocols adapted to international guidelines, at this time, there is no consensus on a routine basis recommendation.
In an article recently published by Kulkarni, an attempt is made to give a brief review of the biomarkers associated with stroke, but leaves aside the determination of circulating cell-free DNA which has been widely studied and cited in multiple articles is not mentioned, said fragments are released shortly after cell death and rupture of the blood–brain membrane in both ischemic and hemorrhagic cerebrovascular disease, with ease for its determination by polymerase chain reaction, correlating with the severity of the cerebrovascular event.,
In the cited article, the biomarker is excluded from the possible options for future research, we recommend increasing the clinical evidence taking into account its promising use is underestimated, however, the author's effort is acknowledged since it shares a general but clear vision of the possibilities to use biomarkers in cerebrovascular disease, revealing the limitations for their present-day use.
