did not experience a traumatic brain injury; have a Glasgow Coma Scale score of lower than 13, are under the age of 16, has a bleeding disorder or is using warfarin, and/or; has a visible open skull fracture. [4] Under the CCTHR, patients with minor head injuries should only receive CT scans if one or more of the following criteria are met: [4]
This means that the HIC includes the effects of head acceleration and the duration of the acceleration. Large accelerations may be tolerated for very short times. At a HIC of 1000, there is an 18% probability of a severe head injury, a 55% probability of a serious injury and a 90% probability of a moderate head injury to the average adult. [4]
Patients may have a history of loss of consciousness but they recover and do not relapse. Clinical onset occurs over hours. Complications include focal neurologic deficits depending on the site of hematoma and brain injury, increased intracranial pressure leading to herniation of brain and ischemia due to reduced blood supply and seizures.
The risk of death from an intraparenchymal bleed in traumatic brain injury is especially high when the injury occurs in the brain stem. [48] Intraparenchymal bleeds within the medulla oblongata are almost always fatal, because they cause damage to cranial nerve X, the vagus nerve, which plays an important role in blood circulation and breathing ...
[12] [13] All traumatic brain injuries are head injuries, but the latter term may also refer to injury to other parts of the head; [14] [15] [16] however, the terms head injury and brain injury are often used interchangeably. [17] Similarly, brain injuries fall under the classification of central nervous system injuries [18] and neurotrauma. [19]
Brain injury can occur at the site of impact, but can also be at the opposite side of the skull due to a contrecoup effect (the impact to the head can cause the brain to move within the skull, causing the brain to impact the interior of the skull opposite the head-impact). While impact on the brain at the same site of injury to the skull is the ...
More than 50% of patients who suffer from a traumatic brain injury will develop psychiatric disturbances. [6] Although precise rates of anxiety after brain injury are unknown, a 30-year follow-up study of 60 patients found 8.3% of patients developed a panic disorder, 1.7% developed an anxiety disorder, and 8.3% developed a specific phobia.

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.
