For an elderly patient with a hematoma and symptoms after a fall, what is the most likely cause?

In the context of an elderly patient who has sustained a fall and presents with a hematoma along with neurological symptoms, the most likely cause is a subdural hematoma. This type of hematoma commonly occurs in older adults due to the greater susceptibility of the brain to movement within the skull as the brain shrinks with age, coupled with the fragility of bridging veins. A fall can easily cause these veins to tear, resulting in bleeding between the brain's surface and the dura mater.

Subdural hematomas often develop slowly and can manifest with symptoms such as confusion, headache, or changes in consciousness, making them a pertinent consideration in elderly patients after trauma. The age factor and the typical clinical presentation align with this diagnosis. In contrast, other types of hematomas or conditions may not commonly present in this manner or might require different mechanisms or circumstances to be likely.
