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...

Depression, Inflammation and Brain Health

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

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...

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...

Mood and Blue Light

Posted in Brain Health, Mood Support

BMC Psychiatry. 2016 Feb 18;16:27. doi: 10.1186/s12888-016-0729-5. 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...

Med Hypotheses. 2011 Oct;77(4):692-5. doi: 10.1016/j.mehy.2011.07.019. Epub 2011 Aug 9. Severe mood dysregulation: in the “light” of circadian functioning. Heiler S1, Legenbauer T, Bogen T, Jensch T, Holtmann M. Author information Abstract Severe affective and behavioral dysregulation, labeled as severe mood dysregulation (SMD), is a widely spread phenomenon among adolescent psychiatric patients. This phenotype constitutes severe impairment across multiple settings, including various symptoms, such as non-episodic anger, mood instability, and hyperarousal. Moreover, SMD patients often show depression and reduced need for sleep. Despite a lifetime prevalence...

Wonderful to see Harvard recognizing the effectiveness of light therapy to a broad range of imbalances in the mind and body. Harv Rev Psychiatry. 2015 May-Jun;23(3):188-94. doi: 10.1097/HRP.0000000000000078. The psychiatry of light. Schwartz RS1, Olds J. Author information Abstract Bright light therapy and the broader realm of chronotherapy remain underappreciated and underutilized, despite their empirical support. Efficacy extends beyond seasonal affective disorder and includes nonseasonal depression and sleep disorders, with emerging evidence for a role in treating attention-deficit/hyperactivity disorder, delirium, and dementia. A practical overview is offered,...
