• Brain edema can be classified into five types. In clinical practice several types may coexist but identification of the predominant type may guide therapy.
• In some conditions non-specific intracranial pressure reduction therapy can be used to improve cerebral perfusion pressure, reduce edema formation, and increase edema resolution.
• Edema associated with hydrocephalus or brain tumors may best be treated using cerebrospinal fluid drainage and steroids respectively.
• Increased understanding of the biochemical mediators of edema genesis is leading to successful experimental therapeutic intervention with novel agents. Their efficacy in the clinical situation remains a subject for investigation.
