Though multifactorial in etiology,\n similarities to terrestrial idiopathic intracranial hypertension (IIH) suggest these changes may result from an increase or impairing in intracranial pressure (ICP). Finding a portable, accessible, and reliable method of monitoring ICP is, therefore, crucial in long duration spaceflight. A\n review of recent literature was conducted on the biomedical literature search engine PubMed using the search term \u201cnon-invasive intracranial pressure\u201d. Studies investigating accuracy of noninvasive and portable methods were assessed. The search retrieved different methods that\n were subsequently grouped by approach and technique. The majority of publications included the use of ultrasound-based methods with variable accuracies. One of which, noninvasive ICP estimation by optical nerve sheath diameter measurement (nICP_ONSD), presented the highest statistical correlation\n and prediction values to invasive ICP, with area under the curve (AUC) ranging from 0.75 to 0.964. One study even considers a combination of ONSD with transcranial Doppler (TCD) for an even higher performance. Other methods, such as near-infrared spectroscopy (NIRS), show positive and promising\n results [good statistical correlation with invasive techniques when measuring cerebral perfusion pressure (CPP): r = 0.83]. However, for its accessibility, portability, and accuracy, ONSD seems to present itself as the up to date, most reliable, noninvasive ICP surrogate and a valuable spaceflight\n asset.<jats:bold>F\u00e9lix H, Santos Oliveira E. <jats:italic>Non-invasive intracranial pressure monitoring and its applicability in spaceflight<\/jats:italic>.
