Tools and techniques for the rapid, continuous, invasive and/or noninvasive measurement, estimation, and/or prediction of a patients intracranial pressure. In an aspect, some tools and techniques can predict the onset of conditions such as herniation and/or can recommend (and, in some cases, administer) a therapeutic treatment for the patients condition. In another aspect, some techniques employ high speed software technology that enables active, long term learning from extremely large, continually changing datasets. In some cases, this technology utilizes feature extraction, state-of-the-art machine learning and/or statistical methods to autonomously build and apply relevant models in real-time.
