Photobiomodulation (PBM) describes the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying. One of the organ systems of the human body that is most necessary to life, and whose optimum functioning is most worried about by humankind in general, is the brain.The brain suffers from many different disorders that can be classified into three broad groupings: traumatic events (stroke, traumatic brain injury, and global ischemia), degenerative diseases (dementia, Alzheimer's and Parkinson's), and psychiatric disorders (depression, anxiety, post traumatic stress disorder). There is some evidence that all these seemingly diverse conditions can be beneficially affected by applying light to the head. There is even the possibility that PBM could be used for cognitive enhancement in normal healthy people. In this transcranial PBM (tPBM) application, near-infrared (NIR) light is often applied to the forehead because of the better penetration.

Cognitive Function & Memory Enhancement: Stimulates cortical neurons to improve focus, attention, and short-term memory.
Neurodegenerative Diseases: Supports patients with Parkinson’s, Alzheimer’s, and Dementia, slowing neuronal degeneration.
Mood Disorders: Helps regulate dopamine and serotonin levels, supporting relief from depression, anxiety, and stress.
Brain Fog & Fatigue: Improves mental clarity and alertness by enhancing neuron metabolism.

Stroke & TBI Recovery: Promotes microcirculation, oxygenation, and deep neuron repair, supporting long-term rehabilitation.
Severe Cognitive Impairment: Enhances deep-brain metabolic activity, improving mental clarity and executive function.
Chronic Fatigue & Sleep Disorders: Stimulates subcortical areas involved in energy regulation and circadian rhythm.
Neuroprotection & Anti-Inflammation: Reduces oxidative stress and inflammation in deep neural networks, supporting overall brain health.

For optimal results, it is recommended to use the helmet in Pulsed Wave (PW) mode at 40Hz with 100% power, six times per week, for 24 minutes per session, and to adhere to this treatment schedule for 8–12 weeks.
Expected Progress:
After 1–2 weeks: With increased ATP production and improved mitochondrial function, users may notice enhancements in memory and mental clarity.
After 1 month: Cognitive functions such as attention, working memory, executive function, and rule-based learning show significant improvement.
After 2 months: Cellular adaptations lead to enhanced neurophysiological activity, supporting long-term neurological and psychological benefits.
Safety Note:

Near-infrared phototherapy is non-invasive, drug-free, and has no known side effects, making it safe for long-term use.
