Cerebral edema is the cause of death in 5% of all patients with cerebral infarction and mortality after large ischemic strokes with cerebral edema is roughly 20 to 30% despite medical and surgical interventions. [9] [38] Cerebral edema usually occurs between the second and fifth day after onset of symptoms. [9]
According to the Centers for Disease Control, about 1.5 people die each year from a concussion in the US; [need quotation to verify] in most of these cases, the person had received another concussion previously. [13] In the presence of second-impact syndrome, the mortality rate is at best 50% when diffuse cerebral swelling occurs. [44]

The figures in females are in women between 20 and 45 years old. [5] On average, IIH occurs in about one per 100,000 people, and can occur in children and adults. The median age at diagnosis is 30. IIH occurs predominantly in women, especially in the ages 20 to 45, who are four to eight times more likely than men to be affected.
Computed tomography (CT) has become the diagnostic modality of choice for head trauma due to its accuracy, reliability, safety, and wide availability. The changes in microcirculation, impaired auto-regulation, cerebral edema, and axonal injury start as soon as a head injury occurs and manifest as clinical, biochemical, and radiological changes ...
Lee's death was officially ruled the result of cerebral edema — swelling of the brain. While a normal human brain is about 3 pounds, Lee's was reportedly closer to 3½ pounds.
When the low cerebral blood flow persists for a longer duration, this may develop into an infarction in the border zones (areas of poor blood flow between the major cerebral artery distributions). In more severe instances, global hypoxia-ischemia causes widespread brain injury leading to a severe cognitive sequelae called hypoxic-ischemic ...
The excessive pressure damages the endothelial layer and the blood–brain barrier, leading to swelling (edema). The predilection toward the posterior brain may be explained by the reduced density of sympathetic innervation in the posterior circulation compared to the anterior circulation (thus a reduced adaptive capacity to fluctuations or ...
