Insights
Developing reliable blood biomarkers is crucial for early stroke diagnosis, especially in children and young adults. This review evaluates existing biomarkers to improve stroke detection and patient outcomes.
Area of Science:
- Neurology
- Biomarker Discovery
- Clinical Diagnostics
Background:
- Early stroke diagnosis is hindered by a lack of reliable blood biomarkers, leading to higher mortality and disability rates.
- Current screening methods are less effective in young adults and children, causing diagnostic delays.
- There is a critical need for accurate blood biomarkers for stroke triage across all age groups.
Purpose of the Study:
- To review existing single blood biomarkers and biomarker panels for stroke prediction.
- To analyze the sensitivity, specificity, clinical utility, and time-window of identified biomarkers.
- To inform future research for developing more effective stroke diagnostic tools.
Main Methods:
- A systematic literature review was conducted using PubMed and Web of Science.
- Articles published in English between 2001 and 2021 concerning stroke biomarkers were included.
- Comparative analysis of seven single biomarkers and five biomarker panels was performed.
Main Results:
- The review identified and compared seven single biomarkers and five biomarker panels for stroke prediction.
- Data on the availability, clinical usefulness, and time-window for each biomarker were compiled.
- Sensitivity and specificity data were examined for their effectiveness in emergency stroke situations.
Conclusions:
- Existing blood biomarkers show potential but require further validation for widespread clinical use.
- The identified biomarkers and panels offer a foundation for developing improved stroke diagnostic strategies.
- Enhanced biomarker research is essential to overcome current diagnostic challenges in stroke patients of all ages.
Abstract:
Early stroke diagnosis remains a big challenge in healthcare partly due to the lack of reliable diagnostic blood biomarkers, which in turn leads to increased rates of mortality and disability. Current screening methods are optimised to identify patients with a high risk of cardio-vascular disease, especially among the elderly. However, in young adults and children, these methods suffer low sensitivity and specificity and contribute to further delays in their triage and diagnosis. Accordingly, there is an urgent need to develop reliable blood biomarkers for triaging patients suspected of stroke in all age groups, especially children and young adults. This review explores some of the existing blood biomarkers, as single biomarkers or biomarker panels, and examines their sensitivity and specificity for predicting stroke. A review was performed on PubMed and Web of Science for journal articles published in English during the period 2001 to 2021, which contained information regarding biomarkers of stroke. In this review article, we provide comparative information on the availability, clinical usefulness, and time-window periods of seven single blood biomarkers and five biomarker panels that have been used for predicting stroke in emergency situations. The outcomes of this review can be used in future research for developing more effective stroke biomarkers.
