When your brain bounces back and forth?
What is a concussion? During the impact of an accident, the brain bounces back and forth inside the skull. This can cause bruising, bleeding, and tearing (Fig. 1).
What is considered a traumatic brain injury?
Definition. Traumatic brain injury (TBI), a form of acquired brain injury, occurs when a sudden trauma causes damage to the brain. TBI can result when the head suddenly and violently hits an object, or when an object pierces the skull and enters brain tissue.
How long can symptoms of a concussion last?
Concussion recovery and treatment. Approximately 80 percent of concussions resolve over seven to 14 days, with an average of 10 days. People with concussions should never return to sports or other physical activity sooner than one week from sustaining the injury.
What happens with a concussion?
Following a concussion, some people may suffer persisting symptoms, such as memory and concentration problems, mood swings, personality changes, headache, fatigue, dizziness, insomnia and excessive drowsiness for several weeks to months. This is known as post-concussive syndrome.
What is COO Contra coo?
Coup and contrecoup (pronounced “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.
How does the brain heal from a concussion?
The brain “heals” itself following a TBI by rerouting neural connections and dispersing a damaged neuron’s job throughout a new network.
What is Contre Coup?
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.
What is coup and countercoup?
A blow to a stationary but moveable head causes acceleration, and the brain floating in CSF lags behind, sustaining an injury directly underneath the point of impact (coup injury). When a moving head hits the floor, sudden deceleration results in an injury to the brain on the opposite side (countercoup injury).
What does raccoon eyes indicate?
Raccoon eyes is a condition that refers to bruises around both eyes. These bruises look like the dark patches around the eyes that are characteristic of raccoons. Raccoon eyes signal a serious condition related to a skull or brain injury. Prompt diagnosis is crucial to reduce the risk of complications.
What is a halo test?
In nursing, the halo sign is the result of a test to see if drainage from a head injury contains cerebrospinal fluid. When a Dextrostix or Tes-Tape test gives a positive reading for glucose, the drainage must be further tested because glucose is also found in the blood.
Can a head injury cause bipolar disorder?
In a study from 2014, researchers found that people with a TBI were 28 times more likely to be diagnosed with bipolar disorder. This was especially true when the head trauma occurred between the ages of 11 and 15.
