What is a Coup Contrecoup Brain Injury?

What is a coup contrecoup injury?

Coup and contrecoup (pronounce coo and contra coo) refer to a type of head injury (traumatic brain injury) and reference where the injury occurred relative to the point of impact. A coup injury occurs on the brain directly under the point of impact.  A contrecoup injury occurs on the opposite side of the brain from where the impact occurred. Coup and contrecoup injuries are a type of traumatic brain injury that results in the bruising of the brain.

Most of brain injuries are the result of outside force, meaning something comes in contact with the head. This impact, and the resulting injuries, come in three different types:

  • coup
  • contrecoup
  • coup-contrecoup.

Common Misspellings: coo contracoo, contracoup, coo injury, coop injury, contracoop, contracoo, contrecoo, conracoo brain injury

It’s important to note that these injuries are considered non-penetrating injuries. Coup and contrecoup injuries are most commonly caused by a fall, blunt force trauma, a sport injury, or the force associated with a car or motorcycle accident.

Before we move on with difference between these three terms, it may help to familiarize yourself with some more common terms associated with TBI.

What is the difference between Coup and Contrecoup Injuries?

  • Coup – (pronounced coo) injuries are present on the brain directly below the site of the impact. The surface bruises, cuts, contusions or other marks can help to pinpoint the location. Trauma can range from relatively mild to severe including bruising, swelling and hemorrhaging of the brain.
  • Contrecoup – (pronounced “contra coo”) injuries affect the side of the brain opposite from where impact occurred. They are often overlooked or misdiagnosed because of their location. Contrecoup occurs when a force or blow causes the brain to strike the side of the skull opposite from the point of impact. These injuries often occur in motor vehicle rollover accidents and motorcycle crashes. If not identified, they pose long term risks for victims.
  • Coup-Contrecoup – injuries are the most severe affecting both sides of the brain. The damage occurs to the side under the impact and the opposite side when the brain strikes the skull. Coup-contrecoup injuries are often misdiagnosed resulting in one area being treated and the other overlooked. Permanent brain damage risks are very high with coup-contrecoup injuries.

Never Ignore a Blow to the Head

Traumatic brain injuries of any type are serious. There are hundreds of symptoms and combinations of symptoms that may be present at the time of the injury or may not manifest for days or even weeks following the trauma. If you ever receive a blow to the head, other than just a bump, do not attempt to shake it off and play or work through it. You may have a serious injury and are risking permanent damage if you ignore it. Even ignoring a mild concussion can be fatal if a second injury occurs to the same area prior to healing. If it hurts for more than a couple minutes, if you feel nausea, experience vomiting, dizziness, blurred vision, affected speech, confusion or any other abnormal feeling, seek medical attention immediately. Just as with a stroke, minutes count.

Coup-contrecoup injuries are serious and should be diagnosed and treated as soon as possible. These injuries can cause hematomas (brain bleeding), brain swelling, and problems with the flow of cerebrospinal fluid which surrounds and protects the brain. Blows to the head may also cause skull fragments to enter the brain tissue or place dangerous pressure on the brain.

Damage Caused by Coup and Contrecoup Injury

The most common form of coup-contrecoup injuries are behind the forehead in the frontal lobe and underneath the temples in the temporal lobe. These injuries can result in problems with decision making, speaking, and language comprehension. Depending on the injury, a traumatic brain injury victim may also experience impaired concentration, memory loss, trouble swallowing, loss of balance and coordination, muscle weakness, paralysis, and/or sensory changes.

Contrecoup Concussion

The human brain is made of soft tissue and is protected by the skull and surrounding spinal fluid. These structures are there to safeguard the delicate organ. When a person is struck in the head, or their head is slammed forward like in a car accident, the impact can cause the brain to move around . If the impact is great enough, the brain can slam forward into the skull, and sometimes even continue the momentum and slam into the opposite side. These are coup and contrecoup injuries described above. When this happens, bruising, damage to the blood vessels, and injury to the nerves has occurred; this is called a concussion.

Concussions are often categorized as a mild traumatic brain injury, but that just means they aren’t necessarily life threatening. This doesn’t mean that they aren’t painful and don’t disrupt ones life. After a concussion, your brain doesn’t function normally. This can cause a loss of vision, nausea, loss of balance, confusion, and unconsciousness.

Because a concussion, by definition, is a bruised or damaged brain, they are strongly related to coup contrecoup injury.

Treating Coup, Contrecoup, and Coup-Contrecoup Injuries

Treating the damage caused by a serious coup, contrecoup, and coup-contrecoup type injuries is a battle of time and prevention, since the injuries are usually irreversible. This means that doctors and surgeons will need to treat the injuries right away in order to prevent any further injury or worsening damage. Depending on the case, doctors may treat the injury with simple recovery methods like rest, employ medications to reduce symptoms, or even perform neurosurgery to decrease brain swelling or bleeding.
