The words "concuss" means to shake violently. Cerebral concussion is defined as a transient, temporary, neurogenic dysfunction caused by mechanical force to the brain. Cerebral concussions are the most common form of head injury. Concussions are classified as mild or classic, based on the degree of symptoms, particularly those of unconsciousness and memory

204 Cerebral Concussion loss. Mild concussion is a temporary neurological dysfunction without loss of consciousness or memory. Classic concussion includes temporary neurological dysfunction with unconsciousness and memory loss. Recovery from concussion usually takes minutes to hours. Most concussion patients recover fully within 48 hours, but subtle residual impairment may occur.

In rare cases, a secondary injury caused by cerebral hypoxia and ischemia can lead to cerebral edema and increased intracranial pressure (ICP). Some patients develop a postconcussion syndrome (postinjury sequelae after a mild head injury). Symptoms may be experienced for several weeks and, in unusual circumstances, may last up to 1 year. In rare situations, patients who experience multiple concussions may suffer long-term brain damage. Complications of cerebral concussion include seizures or persistent vomiting. In rare instances, a concussion may lead to intracranial hemorrhage (subdural, parenchymal, or epidural).
