Everything you need to know about this condition
What is Nontraumatic chronic subdural hemorrhage?
Nontraumatic chronic subdural hemorrhage is a type of bleeding in the brain that occurs without any trauma or injury. It is a condition where blood collects in the space between the brain and the skull, causing symptoms such as headaches, confusion, and weakness. This condition is more common in older adults and can be caused by blood thinners or anti-coagulant medications, age-related brain atrophy, or high blood pressure. According to WHO guidelines, nontraumatic chronic subdural hemorrhage is a significant cause of morbidity and mortality in older adults.

- High blood pressure, which can cause blood vessels in the brain to become weakened and prone to bleeding
- Genetic factors, such as a family history of bleeding disorders
