Measurement of intracranial pressure (ICP) is critical for the evaluation and management of many neurological and neurosurgical conditions. The invasiveness of ICP measurement limits the frequency with which ICP can be evaluated, hampering the clinical care of patients with ICP disorders. Thus, there has been substantial interest in developing noninvasive methods for the assessment of ICP. Numerous approaches have been applied to the problem, although none seems to represent a complete solution. The goal of this review is to familiarize the reader with the currently available methods to noninvasively evaluate ICP.
