The useage of near-infrared spectroscopy in the field of cognitive impairment assessment / 中华神经科杂志

Near-infrared spectroscopy (NIRS) is a new optical imaging technique, which can indirectly reflect the auto-regulation of cerebral blood perfusion and the brain activation by monitoring blood oxygen saturation. This technique has been widely used in neurocritical care in recent years. The basic principle of NIRS and its application in cognitive impairment were reviewed, and the comparison of this technique and functional magnetic resonance imaging which has been commonly used in brain activation assessment was discussed. In the future, NIRS is expected to be more widely used in the field of cognitive impairment assessment.
