The evidence supports that transcranial and intranasal photobiomodulation with the Vielight Neuro Gamma has been studied in small clinical trials and pilot work, including home use in people with dementia. These studies suggest possible effects on cognitive measures, cerebral perfusion, and brain connectivity, but the evidence base is still preliminary and not enough to establish clinical efficacy. The product marketing makes stronger claims than the current research supports.

The Vielight Neuro Gamma is a brain photobiomodulation device designed to enhance cognitive function through the use of near-infrared (NIR) light. It employs a combination of transcranial and intranasal technology to deliver pulsed NIR energy at a frequency of 40 Hz, which aligns with gamma brain wave oscillations. This frequency is associated with improved focus, memory, and overall brain energy.

The device operates by transmitting NIR energy through the skull, stimulating brain activity without generating heat. This process, known as photobiomodulation, is supported by independent research and is believed to enhance cognitive functions by increasing cerebral blood flow and activating neuronal mitochondria. The intranasal component targets the ventral brain areas, which are crucial for various cognitive processes.

The Vielight Neuro Gamma is certified as a medical-grade device and is backed by a two-year warranty. It is recommended for use once every other day, with more frequent use suggested for individuals with cognitive impairments. The device is part of a broader category of brain health technologies that aim to improve mental clarity and cognitive performance through non-invasive methods.
