This book contains the papers delivered at the Symposium on "Medical Treatment of Brain Ede- ma" at the Seventh International Congress ofNeu- rological Surgery, held in Munich in 1981. The aim of each speaker was to give a short review of current knowledge in his or her field. In addition, most of the authors presented their own data. The symposium . was divided into two parts. The experimental part focused on pathophysiological and biochemical findings, while the clinical part dealt with therapy for brain edema, with particular emphasis on steroids.
