Background:

  • Stroke occurs when brain blood flow is interrupted, leading to cell death and potential disability.
  • Early symptom recognition is crucial for stroke prediction and proactive health management.
  • Developing accurate long-term risk prediction models is essential for preventative healthcare strategies.

Purpose of the Study:

  • To develop and evaluate machine learning (ML) models for robust long-term stroke risk prediction.
  • To design a framework capable of identifying individuals at high risk of stroke.
  • To compare the performance of various ML models, including a novel stacking method.

Main Methods:

  • Utilized machine learning (ML) algorithms to analyze stroke risk factors.
  • Developed and evaluated several predictive models.
  • Implemented a stacking ensemble method as the primary approach for risk prediction.

Main Results:

  • The stacking classification model achieved high performance across multiple metrics.
  • Achieved an Area Under the Curve (AUC) of 98.9%.
  • Reported F-measure, precision, and recall of 97.4%, with an overall accuracy of 98%.

Conclusions:

  • The developed stacking method provides a highly accurate and robust framework for long-term stroke risk prediction.
  • Machine learning offers a powerful tool for enhancing predictive capabilities in neurological health.
  • The findings support the integration of advanced ML techniques in clinical decision-making for stroke prevention.
