What characteristic distinguishes a chronic subdural hematoma from other types?

A chronic subdural hematoma is primarily characterized by its prevalence in the elderly population and individuals with a history of alcoholism. This group is more vulnerable due to factors such as age-related brain atrophy, which increases the space between the brain and the skull, making it easier for blood to accumulate after a minor head injury that may go unnoticed. Moreover, alcoholics may have coagulopathy or poor nutritional status, increasing their susceptibility to falls and subsequent hematoma formation.

In contrast, other options do not accurately represent the defining traits of a chronic subdural hematoma. While children can experience other types of subdural hematomas, they are not commonly associated with the chronic form. Immediate surgical intervention is not typically required for a chronic subdural hematoma unless it causes significant symptoms or complications, as many can be managed conservatively. Additionally, the presence of fever and chills is not a characteristic of chronic subdural hematomas; these symptoms might suggest an infectious process but are not relevant to the hematoma itself.
