The incidence of this disorder should be considered in terms of its potential causes and is present in most cases of traumatic brain injury, central nervous system tumors, brain ischemia, and intracerebral hemorrhage. In one study, cerebral edema was found in 28% of those individuals with thrombolysis-treated ischemic strokes, 10% of which occurred in severe forms. A further study detected cerebral edema in 22.7% of cerebral ischemic strokes. A meta-analysis of current studies showed that 31% of those affected by ischemic strokes developed cerebral edema in 31% of cases. In traumatic brain injuries, cerebral edema occurred in greater than 60% of those with mass lesions, and in 15% of those with initial normal CT scans. Research
The current understanding of the pathophysiology of cerebral edema after traumatic brain injury or intracerebral hemorrhage is incomplete. Current treatment therapies aimed at cerebral edema and increased intracranial pressure are effective at reducing intracranial hypertension but have unclear impacts on functional outcomes. Additionally, cerebral and ICP treatments have varied effects on individuals based on differing characteristics like age, gender, type of injury, and genetics. There are innumerable molecular pathways that contribute to cerebral edema, many of which have yet to be discovered. Researchers argue that the future treatment of cerebral edema will be based on advances in identifying the underlying pathophysiology and molecular characteristics of cerebral edema in a variety of cases.
At the same time, improvement of radiographic markers, biomarkers, and analysis of clinical monitoring data is essential in treating cerebral edema.Many studies of the mechanical properties of brain edema were conducted in the 2010s, most of them based on finite element analysis (FEA), a widely used numerical method in solid mechanics. For example, Gao and Ang used the finite element method to study changes in intracranial pressure during craniotomy operations. A second line of research on the condition looks at thermal conductivity, which is related to tissue water content. See also
