Concussions in car accidents are typically caused by a forceful impact that leads to rapid head movement, causing the brain to move within the skull. This sudden motion can result in a brain injury.
Common causes of concussions in car accidents include:
- Whiplash: This is a rapid back-and-forth movement of the head that often occurs in rear-end collisions. Whiplash can cause the brain to collide with the interior of the skull.
- Direct impact to the head: This involves striking the head against parts of a car, such as the steering wheel, windows, or dashboard. It can also occur due to impact with loose items inside a car.
- Sudden deceleration: When a vehicle stops abruptly in a crash, the body may be restrained by seat belts, but the head might still jerk forward. This can cause the brain to move violently inside the skull.
- Airbag deployment: Although airbags are crucial for preventing more severe injuries, their rapid deployment can cause a concussion if the head is too close to the airbag at the moment of deployment.
- Roll-over accidents: In these accidents, occupants can be tossed around inside a vehicle. This can cause the head to hit various surfaces.
- Secondary collisions: After the initial crash, secondary impacts, such as being hit by another vehicle or striking a stationary object, can also lead to concussions.
