Subdural hemorrhage symptoms depend on how quickly blood collects inside the skull. In an acute hemorrhage, signs and symptoms will usually appear immediately. With chronic hemorrhaging, leaking blood collects more slowly, and it can take weeks or months for symptoms to appear. Often, the cause is a minor incident that doesn’t stand out as being particularly harmful. Chronic hemorrhaging is more common in older adults, who may develop symptoms that mimic a stroke or dementia.
Symptoms of a subdural hematoma may include:
- Weakness, or numbness on one side of the body
- Speech and comprehension problems
- Nausea or vomiting
