Which type of intracranial hemorrhage may lead to sudden loss of consciousness?

Sudden loss of consciousness can occur with various types of intracranial hemorrhages, and each type has distinct characteristics that can lead to this symptom.

Epidural hemorrhage typically occurs due to trauma that causes a rupture of the middle meningeal artery. This type of hemorrhage can develop rapidly and often follows a "lucid interval" where the patient may initially be alert before losing consciousness suddenly as increased intracranial pressure or fluctuating intracranial conditions occur.

Subdural hemorrhage, often resulting from the tearing of bridging veins in cases of acceleration-deceleration trauma, can also lead to loss of consciousness. This may happen acutely or become chronic, but its sudden occurrence can present with changes in consciousness due to the gradual accumulation of blood exerting pressure on the brain over time.

Intracerebral hemorrhage, which involves bleeding directly into the brain tissue itself, is frequently associated with hypertension, vascular anomalies, or trauma. It can lead to rapid changes in neurological status, including sudden loss of consciousness, as the expanding mass effect from the hematoma disrupts normal brain function.

Given that each of these types can independently result in a sudden loss of consciousness due to their mechanisms of injury and the consequent intracranial
