Can a concussion cause permanent loss of consciousness?

A concussion can cause a temporary loss of consciousness, typically lasting only a few seconds or minutes. However, it should not lead to permanent unconsciousness. Permanent loss of consciousness could be a sign of a more severe brain injury, such as a traumatic brain injury (TBI) or brain hemorrhage, which requires immediate and emergency medical attention. The duration of unconsciousness and memory loss can indicate the severity of the concussion. Even when consciousness is regained, it’s crucial to seek medical evaluation as other serious symptoms might develop over time.
