Infrared Light for Memory Loss in Mild Cognitive Impairment (MCI)

The Neuro RX Gamma (version 2) delivers a synchronized pulse frequency of 40 Hz from all LED clusters. The gamma pulse frequency of 40 Hz has been demonstrated to attenuate amyloid beta proteins production in the hippocampus and modulate microglial activity resulting in increased scavenging of amyloid beta which may lead to improving cognition in MCI. Finally, the Vielight Neuro RX Gamma (version 2) has been designed to target the delivery of NIR energy to particular brain regions; specifically the default mode network (DMN). The active intervention device proceeds to deliver light to each LED at 40 Hz with a 50% duty cycle for 20 minutes and stops automatically. During the 20 minute treatment the power indicator LED on the controller flashes green at 40 Hz. The operator is notified that the treatment is finished when the power indicator LED on the controller stops flashing and the device beeps 2 times.

The sham device delivers infrared light for only a few seconds before stopping. The controller will still show a green light to maintain the study\'s blinding. If the headset is removed, the device will emit a beep and cease functioning.
