From severity scoring to predictive analytics: the emerging role of AI in neurosurgery

The rapid integration of artificial intelligence (AI) into neurosurgical practice is transforming every phase of patient care from diagnostic imaging and preoperative planning to intraoperative decision-making and postoperative management. This narrative review traces the evolution of data-driven neurosurgery, beginning with traditional severity scoring systems and advancing toward predictive analytics and intelligent automation. By examining structured data (such as electronic health records and laboratory valu…

The quick read

By its publication date of January 1, 2026, this narrative review in Frontiers in Neurology traced the shift from traditional severity scoring to AI-driven predictive analytics in neurosurgery, summarizing how models use EHRs, labs, imaging, videos, and notes across diagnosis, planning, intraoperative decision-making, and postoperative management.

The synthesis matters because it links reported model performance to direct patient-care tasks like tumor segmentation and outcome forecasting, while uncertainty remains around generalizability, bias, interpretability, and regulatory pathways, with future work proposed around federated learning and continuous learning ecosystems.

Main points
  • Review covers structured data such as electronic health records and laboratory values and unstructured inputs including neuroimaging, surgical videos, and free-text notes.
  • Reported performance includes Dice 0.82-0.84 for tumor segmentation and AUC 0.80-0.90 for molecular prediction and outcome forecasting.
  • Applications discussed include lesion detection, surgical navigation, prognostication, and rehabilitation.
  • Emerging paradigms noted are federated learning, generative AI, and continuous learning ecosystems.
Gain

AI models applied to neurosurgical data achieved Dice scores of 0.82-0.84 for tumor segmentation and AUC values of 0.80-0.90 for molecular prediction and outcome forecasting, supporting lesion detection, surgical navigation, and prognostication.

The rundown

The review describes how AI extracts clinically meaningful patterns from both structured EHR and lab data and unstructured neuroimaging, surgical video, and notes, enabling lesion detection, navigation, prognostication, and rehabilitation support.

It reports prior study metrics of Dice 0.82-0.84 for segmentation and AUC 0.80-0.90 for molecular and outcome prediction, while noting ongoing issues of interpretability, harmonization, bias, and regulation, and pointing to federated learning and generative AI as future directions.
