To determine non-invasive physiologic and environmental biomarkers that can effectively forecast seizures in pediatric epilepsy patients, addressing the critical need for improved seizure prediction methods.
Key Findings:
Eleven observational cohort studies were included, primarily focusing on cardiovascular biomarkers using ECG measurements.
Pre-ictal anticipation algorithm times ranged from 21.8 seconds to 32 minutes, indicating variability in prediction accuracy.
Cardiovascular biomarker changes were observed 3.59 seconds to 40 minutes before seizures, highlighting the potential for early detection.
9 out of 11 studies were rated as low or very low certainty due to methodological flaws and risk of bias, which limits the reliability of the findings.
Interpretation:
The review highlights the potential of cardiovascular biomarkers for seizure forecasting but indicates a need for improved study designs and larger sample sizes to enhance evidence quality, particularly given the low certainty ratings.
Limitations:
Methodological flaws in the majority of studies limit the reliability of findings.
Risk of bias and inconsistent results further complicate the interpretation of the data.
Indirect or sparse evidence in the reviewed studies raises concerns about the generalizability of the results.
Conclusion:
There is a significant opportunity to advance seizure forecasting through further research on cardiovascular biomarkers, their integration with other factors, and the exploration of innovative methodologies.
