Good Light & Bad Light for the Brain

Posted in Brain Health, How Light Energy is Being Used Worldwide

Brain health, dopamine levels and light. Wow! This study found that flourescent lighting sources induced neurodegeneration lowering dopamine levels by as much as 30% in the brain of mice while near infrared light was beneficial to the brain and helped it maintain healthy levels of dopamine. Low dopamine is found in Parkinsons and other neurodegenerative diseases. This was with only 3 months of exposure. Powerful insight – “light can be detrimental or beneficial to DA neurons in SN, depending on the source and wavelength.” SHINE WITH THE RIGHT LIGHT Brain Res. 2017 May 1;1662:87-101. doi: 10.1016/j.brainres.2017.02.026.

Near Infrared Light Affects Mood and Cognition

Posted in Brain Health, Mood Support

Interesting how this study shines near infrared light through the skull of beagles to induce changes in the cellular metabolism in the brain.  The measured increased metabolic energy in the brain affects mood and cognition. Photomed Laser Surg. 2017 Feb 9. doi: 10.1089/pho.2016.4238. [Epub ahead of print] Effects of Near-Infrared Light on Cerebral Bioenergetics Measured with Phosphorus Magnetic Resonance Spectroscopy. Mintzopoulos D1, Gillis TE1, Tedford CE2, Kaufman MJ1. Author information Abstract OBJECTIVE: Cerebral photobiomodulation (PBM) improves mood and cognition. Cerebral metabolic enhancement is a mechanism proposed to underlie PBM effects. No PBM studies to...

BBA Clin. 2016 Oct 1;6:113-124. eCollection 2016. Shining light on the head: Photobiomodulation for brain disorders. Hamblin MR1. Author information Abstract 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...

Red and Infrared Light Go Deep Into the Brain

Posted in Brain Health

Phys Med Biol. 2015 Apr 7;60(7):2921-37. doi: 10.1088/0031-9155/60/7/2921. Epub 2015 Mar 19. Red and NIR light dosimetry in the human deep brain. Pitzschke A1, Lovisa B, Seydoux O, Zellweger M, Pfleiderer M, Tardy Y, Wagnières G. Author information 1Federal Institute of Technology (EPFL), Institute of Chemical Sciences and Engineering (ISIC), 1015 Lausanne, Switzerland. Abstract Photobiomodulation (PBM) appears promising to treat the hallmarks of Parkinson’s Disease (PD) in cellular or animal models. We measured light propagation in different areas of PD-relevant deep brain tissue during transcranial, transsphenoidal illumination (at 671 and 808 nm) of a cadaver...

Neurophotonics. 2016 Jul;3(3):031404. doi: 10.1117/1.NPh.3.3.031404. Epub 2016 Mar 4. Review of transcranial photobiomodulation for major depressive disorder: targeting brain metabolism, inflammation, oxidative stress, and neurogenesis. Cassano P1, Petrie SR2, Hamblin MR3, Henderson TA4, Iosifescu DV5. Author information Abstract We examined the use of near-infrared and red radiation (photobiomodulation, PBM) for treating major depressive disorder (MDD). While still experimental, preliminary data on the use of PBM for brain disorders are promising. PBM is low-cost with potential for wide dissemination; further research on PBM is sorely needed. We found clinical and...

Parkinsons, Deep Brain Health & Light

Posted in Brain Health, How Light Energy is Being Used Worldwide

Exciting to see how deeply Red and Near Infrared light can penetrate into the brain tissue.  The authors find promising to use light to support those with Parkinson’s or other neurodegenerative diseases.   We have personally seen several people with Parkinson’s respond well to using light energy applied over their eyes and sinuses.  Check their experiences out the testimonials section of this site. Phys Med Biol. 2015 Apr 7;60(7):2921-37. doi: 10.1088/0031-9155/60/7/2921. Epub 2015 Mar 19. Red and NIR light dosimetry in the human deep brain.

Behav Brain Funct. 2009 Dec 8;5:46. doi: 10.1186/1744-9081-5-46. Psychological benefits 2 and 4 weeks after a single treatment with near infrared light to the forehead: a pilot study of 10 patients with major depression and anxiety. Schiffer F1, Johnston AL, Ravichandran C, Polcari A, Teicher MH, Webb RH, Hamblin MR. Author information Abstract BACKGROUND: Many studies have reported beneficial effects from the application of near-infrared (NIR) light photobiomodulation (PBM) to the body, and one group has reported beneficial effects applying it to the brain in stroke patients. We have reported that the measurement of a patient’s left and right hemispheric...

The effects of low-intensity narrow-band blue-light treatment compared to bright white-light treatment in sub-syndromal seasonal affective disorder. Meesters Y1, Winthorst WH2, Duijzer WB3, Hommes V4. Author information Abstract BACKGROUND: The discovery of a novel photoreceptor in the retinal ganglion cells with a highest sensitivity of 470-490 nm blue light has led to research on the effects of short-wavelength light in humans. Several studies have explored the efficacy of monochromatic blue or blue-enriched light in the treatment of SAD. In this study, a comparison has been made between the effects of...
