Which of the following mechanisms of injury would likely result in coup Contrecoup trauma?
Coup and contrecoup injuries are most commonly caused by a fall, blunt force trauma, a sports injury, or the force associated with a car or motorcycle accident.
How does coup Contrecoup affect the brain?
Closed head injury (coup contrecoup) can damage more than the impact sites on the brain, as axon bundles may be torn or twisted, blood vessels may rupture, and elevated intracranial pressure can distort the walls of the ventricles. Diffuse axonal injury is a key pathology in concussive brain injury.
Which brain region is the most susceptible to coup Contrecoup injury?
As the skull then stops, the brain once again impacts on the internal surface of the skull resulting in damage. Areas most frequently affected are the inferior surface of the frontal lobes and temporal poles 3. An unusual form of contrecoup injury is traumatic lens dislocation of the eye 1.
What does coup Contrecoup cause?
The cause of a coup contrecoup injury usually involves the rapid acceleration and deceleration of the brain. Due to this sudden movement, the brain collides with the skull, disrupting and potentially damaging neurons, blood vessels, axons, and other important neural structures.
What are some examples of traumatic brain injuries?
Traumatic brain injury (TBI) is sudden damage to the brain caused by a blow or jolt to the head. Common causes include car or motorcycle crashes, falls, sports injuries, and assaults. Injuries can range from mild concussions to severe permanent brain damage.
Can a severe head injury cause problems years later?
While most people are symptom-free within two weeks, some can experience problems for months or even years after a minor head injury. The more severe the brain injury, the more pronounced the long-term effects are likely to be.
Can you recover from anoxic brain injury?
A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of making a full or partial recovery. Furthermore, symptoms and effects of the injury are dependent on the area(s) of the brain that was affected by the lack of oxygen.
What is the difference between primary and secondary brain injury?
Whereas primary brain injury (focal and diffuse) results from mechanical injury at the time of the trauma, secondary brain injury is caused by the physiologic responses to the initial injury.
What is a second impact syndrome?
Second impact syndrome, or SIS, happens when the brain swells rapidly shortly after a person suffers a second concussion before symptoms from an earlier concussion have subsided.
What are symptoms of frontal lobe damage?
Some potential symptoms of frontal lobe damage can include:
- loss of movement, either partial (paresis) or complete (paralysis), on the opposite side of the body.
- difficulty performing tasks that require a sequence of movements.
- trouble with speech or language (aphasia)
- poor planning or organization.
What are at least 5 symptoms of mild traumatic brain injury?
