AI in Neurology: Stroke Triage, Brain Imaging, and EEG
Neurology has the clearest case in medicine for AI measured in minutes rather than accuracy points, and three very different problems that AI is being applied to.

AI in Neurology
AI in brain imaging, stroke detection, neurodegenerative disease research, and neurological diagnosis.
Overview
Neurology is applying AI to brain MRI analysis, stroke triage, seizure detection, and early identification of conditions like Alzheimer's and Parkinson's disease. Time-sensitive applications like stroke triage have seen strong AI integration.
Neurology has the clearest case in medicine for AI measured in minutes rather than in accuracy points. In large vessel occlusion stroke, the interval between imaging and intervention is the outcome variable, and a device that compresses it can improve care without ever being a better reader than the radiologist.
That is why the first computer-aided triage authorization in the United States was a stroke device, and why the CADt category exists at all.
Three distinct problems
Stroke triage is a speed problem. Brain volumetry is a measurement problem, because radiologists describe atrophy qualitatively and inconsistently while clinically meaningful year-over-year change sits below what visual inspection detects. Continuous EEG is a volume problem: days of recording that no one can read in full, where automated detection is not an accuracy improvement over an expert but the only way the data gets examined at all.
Clinical Use Cases
- Stroke detection and large vessel occlusion triage
- Brain MRI lesion detection
- EEG seizure detection
- Alzheimer's and Parkinson's screening
- Neurosurgical planning support
Where The Evidence Actually Stands
Stroke triage has the best real-world evidence in this specialty, though most reported time savings come from transfer-network studies and will not reproduce in a single-site hospital with an in-house interventional team. Volumetric quantification is highly sensitive to acquisition parameters, and comparing scans across scanners can produce apparent change that is entirely technical. EEG detection carries high false-positive rates in artifact-heavy intensive care recordings.
