Published this week in the Neuropsychiatric Disease and Treatment, the study "Near-infrared photonic energy penetration: can infrared phototherapy effectively reach the human brain? The findings include:. Previous work by Henderson and others has shown that the most common areas injured in the human brain are the bottom of the frontal lobes and the temporal lobes which can be cm from the scalp. The Center for Disease Control reports more 2. According to Dr. Henderson, symptoms of persistent TBI can include headaches, speech irregularities, confusion, memory slips, lack of impulse control, sleep disturbance, anxiety, depression, and for some, suicide. We must caution consumers against claims of benefit from treatments using NIR at the milliwatt level," said Dr.

Traumatic brain injury TBI is a growing health concern effecting civilians and military personnel. Research has yielded a better understanding of the pathophysiology of TBI, but effective treatments have not been forthcoming. Yet, it remains unclear if sufficient photonic energy can be delivered to the human brain to yield a beneficial effect. This paper reviews the pathophysiology of TBI and elaborates the physiological effects of NIR in the context of this pathophysiology. Pertinent aspects of the physical properties of NIR, particularly in regards to its interactions with tissue, provide the background for understanding this critical issue of light penetration through tissue.
Infrared IR light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 0. This range of wavelengths corresponds to a frequency range of approximately 1 to THz, and includes most of the thermal radiation emitted by objects near room temperature. Infrared light is emitted or absorbed by molecules when they change their rotational-vibrational movements.
There are only two ways you can see something in the world. The first is to have an object that emits light. The light from this object then enters your eye and your brain interprets it. Examples of this type of object are lights and your computer monitor.
