Among the most severe traumatic brain injuries (TBIs) are coup and contrecoup injuries, which occur when the brain suffers localized trauma from a sudden impact. These injuries often lead to brain bruising (contusions), swelling, or hemorrhaging, with the potential for long-term complications.
If your injury was caused by someone else’s negligence, an experienced traumatic brain injury lawyer can help you pursue damages for medical expenses, lost wages, and pain and suffering.
The Science Behind Coup and Contrecoup Brain Injuries
Brain injuries occur when sudden acceleration or deceleration causes the brain to move inside the skull. Unlike concussions, which may affect a broader area of the brain, coup and contrecoup injuries cause focal trauma at specific impact sites.
What Is a Coup Injury?
A coup injury happens directly beneath the point of impact when a sudden blow causes the brain to collide with the inner skull at the impact site. This type of injury is common in situations where a stationary head is struck by a moving object, resulting in bruising, swelling, or internal bleeding.
Common Causes of Coup Injuries Include:
- Falling objects striking the head, such as in construction site accidents or workplace injuries.
- Direct head impact in a motor vehicle accident, such as a driver hitting their head against the dashboard or steering wheel during a collision.
- Blunt force trauma, often seen in assault cases or sports injuries involving head contact.
What Is a Contrecoup Injury?
A contrecoup injury occurs on the opposite side of the brain from the initial impact. This happens when an external force causes the brain to shift violently inside the skull, rebounding and striking the inner surface on the opposite side.
Common Causes of Contrecoup Injuries Include:
- High-speed car crashes, where sudden deceleration forces the brain to move within the skull, hitting the opposite side.
- Severe whiplash injuries, often seen in rear-end collisions, where the head jerks forward and backward, leading to both coup and contrecoup injuries.
- Falls from significant heights, where the initial impact causes a secondary brain collision within the skull.

Why Coup and Contrecoup Injuries Often Occur Together
In high-impact accidents, both coup and contrecoup injuries frequently develop, creating multiple points of brain trauma. For example:
- A head-on car crash can cause a coup injury at the front of the brain when the driver’s head hits the dashboard, followed by a contrecoup injury at the back when the brain rebounds inside the skull.
- A fall onto a hard surface may cause a coup injury at the back of the brain at the moment of impact, followed by a contrecoup injury at the front of the brain as it shifts within the skull.
These injuries can be diagnosed through CT scans and MRIs, which detect intracranial bleeding, swelling, and contusions.
How Do These Injuries Happen?
Coup and contrecoup brain injuries occur in accidents where the head experiences sudden, violent movement or impact. Among the most common causes are motor vehicle collisions, falls, workplace injuries, and sports-related trauma.
High-Impact Collisions and Car Accidents
Motor vehicle crashes are one of the leading causes of traumatic brain injuries. The force of a collision can result in both coup and contrecoup injuries, as the brain moves forward and backward within the skull.
The Role of Whiplash in Causing Secondary Brain Injuries
Whiplash is common in rear-end collisions, where the head rapidly moves forward and backward, forcing the brain to accelerate and decelerate inside the skull. This motion can lead to both coup and contrecoup injuries, even when the head does not physically strike anything.
How Reckless Driving Increases the Risk of Traumatic Brain Injuries
Reckless or negligent driving behaviors significantly contribute to severe head trauma. Under Virginia Code § 46.2-852, reckless driving is defined as operating a vehicle in a way that endangers others.
Some of the most dangerous reckless driving behaviors include:
- Speeding, which increases impact force and severity of brain trauma.
- Failure to yield or running red lights, leading to T-bone crashes that result in head injuries.
- Driving under the influence, which slows reaction time and impairs judgment, leading to higher-impact collisions.
Falls and Blunt Force Trauma
Falls account for a large percentage of traumatic brain injuries, especially among elderly individuals and workers in hazardous environments.
How Falls Cause Different Types of Brain Injuries
- A fall from a height, such as a construction accident, may cause a coup injury at the impact site and a contrecoup injury as the brain rebounds.
- A ground-level slip-and-fall accident can lead to brain injuries due to sudden, forceful movement, even without external head trauma.
Victims who suffer TBIs in falls may have legal options if property owners failed to maintain safe conditions. If your injury was caused by unsafe premises, a slip-and-fall accident lawyer can help establish liability.
Sports, Violence, and Workplace Accidents
Coup and contrecoup injuries frequently occur due to physical assaults, contact sports, and workplace accidents.
- Football, boxing, and hockey players are at high risk for repeat head trauma, leading to chronic brain injuries.
- Physical assaults, such as punches or blunt force trauma, can result in dual-impact brain injuries.
- Workplace accidents involving falling objects or heavy machinery increase the risk of serious head injuries.
