Lobar Brain Bleeds Carried 3.49x Dementia Risk in NLP Stroke-Subtype Study
A 2026 Scottish health-system preprint used natural language processing of CT and MRI reports to subtype stroke and found that lobar intracerebral hemorrhage carried a higher dementia risk beyond 6 months, aHR 3.49 vs matched controls.1 The method reduced unspecified stroke coding from 26.1% to 3.4%, making location-specific prognosis easier to see.
