This book gathers the proceedings of the 17^th International Conference on Intracranial Pressure and Neuromonitoring, held in Leuven, Belgium in September 2019. It provides an overview of the current understanding, underlying research and future perspectives concerning pathophysiology, biophysics, monitoring and management in traumatic and non-traumatic acute brain injury, hydrocephalus and spinal cord injury, including cerebrovascular autoregulation impairment in neurological as well as non-neurological diseases. The peer-reviewed contributions were prepared by specialists in neurosurgery, neurointensive care and neuroanesthesiology, as well as prominent experts from the fields of physiology, clinical and biomedical engineering, mathematics and informatics. The book continues the time-honored tradition of publishing key presentations from the ICP Conferences in order to facilitate their dissemination within the clinical and research community.
