This book is organized according to the UCNS Neurocritical Care core curriculum outline (attached) to ensure that all topics represented on the boards are covered, and include both neuroscience critical care (general neurology, neurotrauma, neurovascular and neurosurgical problems) and general critical care topics (systems trauma, cardiovascular, infectious disease, pulmonary, and renal issues, and hemodynamic monitoring). A set of 25 to 50 questions is generated for each subject on the syllabus, depending on the breadth of the topic and its relative weight or importance on the test. A detailed explanation will follow in the answer section of each chapter. Neuroimaging, EEG and monitoring waveforms, anatomical drawings, histology slides, and transcranial dopplers will be included in case questions to allow candidates to familiarize themselves with these tools as they form a significant part of the exam.
