A concussion, also known as a mild traumatic brain injury (mTBI), is a head injury that temporarily affects brain functioning. [8] Symptoms may include headache, dizziness, difficulty with thinking and concentration, sleep disturbances, mood changes, a brief period of memory loss, brief loss of consciousness; problems with balance; nausea; blurred vision; and mood changes.
Closed-head injuries are caused primarily by vehicular accidents, falls, acts of violence, and sports injuries. [4] Falls account for 35.2% of brain injuries in the United States, with rates highest for children ages 0–4 years and adults ages 75 years and older. [3] Head injuries are more common in men than women across every age group. [3]
A traumatic brain injury (TBI), also known as an intracranial injury, is an injury to the brain caused by an external force. TBI can be classified based on severity ranging from mild traumatic brain injury (mTBI/concussion) to severe traumatic brain injury. [ 5 ]
In head injury, a coup injury occurs under the site of impact with an object, and a contrecoup injury occurs on the side opposite the area that was hit. [1] Coup and contrecoup injuries are associated with cerebral contusions, [2] a type of traumatic brain injury in which the brain is bruised. Coup and contrecoup injuries can occur individually ...
A cerebral laceration is a similar injury except that, according to their respective definitions, the pia-arachnoid membranes are torn over the site of injury in laceration and are not torn in contusion. [4] [5] The injury can cause a decline in mental function in the long term and in the emergency setting may result in brain herniation, a life ...
1–24 hours – the injury is moderate in severity and full recovery is expected. The patient may experience some minor post-concussive symptoms (e.g. headaches, dizziness). 1–7 days – the injury is severe, and recovery may take weeks to months. The patient may be able to return to work, but may be less capable than before the injury.
Acute concussion symptoms (those that occur shortly after an injury) should not be confused with CTE. Differentiating between prolonged post-concussion syndrome (PCS, where symptoms begin shortly after a concussion and last for weeks, months, and sometimes even years) and CTE symptoms can be difficult.
Although it is a diffuse type of brain injury itself, diffuse vascular injury is generally more likely to be caused by focal than diffuse injury. [4] Swelling, commonly seen after TBI, can lead to dangerous increases in intracranial pressure. [4] Though swelling itself is a diffuse type of injury, it can result from either focal or diffuse ...
