Chronic subdural hematomas often occur in older adults and are typically associated with the gradual enlargement of the subdural space resulting from brain atrophy. As the brain shrinks, the distance between the brain surface and the dura mater increases, placing stress on the bridging veins that extend over this space. These vessels can become more susceptible to tearing due to the increased mobility of the brain within the skull.

This is particularly important in the elderly or individuals with certain neurological conditions where atrophy is more pronounced. The slow accumulation of blood from the torn veins over time can lead to significant symptoms that may develop insidiously. In contrast to more acute brain injuries that result from severe head trauma or vascular incidents such as aneurysm rupture, chronic subdural hematomas are characterized by a more gradual onset and deterioration of function. Understanding this mechanism is crucial in diagnosing and treating chronic subdural hematomas effectively.
