Recent studies have extensively explored the link between ischemic strokes and dementia . However, the impact of non-traumatic intracranial hemorrhage (ICH) on dementia risk remains largely understudied. To bridge this gap, a study has analyzed insurance claim data from 2.1 million individuals over a median follow-up of 5.6 years to determine whether ICH contributes to dementia development. The study found that dementia was diagnosed in 17.1% of patients with ICH compared to 12.8% of those without ICH.
Notably, the incidence rate of dementia was significantly higher in ICH patients (8.6% vs. 2.2%), with the risk of developing dementia doubling (HR – 2.0) compared to non-ICH patients. Furthermore, a higher risk of incident dementia was observed consistently across subtypes of ICH, including intracerebral hemorrhage (HR – 2.4), subarachnoid hemorrhage (HR – 1.99), and subdural hemorrhage…
