Extensive research is ongoing in the use of Photobiomodulation (PBM, often referred to as low-level or cold laser therapy) to treat Alzheimer’s disease as well as other debilitating diseases. The following case studies further confirm that PBM could be a breakthrough approach to limit the progression of insidious diseases. We present four cases, two with mild to moderate dementia and two with more advanced symptoms. Several publications have shown beneficial results, however, several weeks of daily treatments were necessary. The cases described here suggest that moderate and advanced dementia cases can be significantly improved with three or four eight-minute treatments over a 5 - 7-day period when using super-pulsing technology on Monday-Wednesday-Friday schedule (Figure 1). Gives a brief visual explanation of super-pulsing versus continuous wave technology.

Background: Brain disorders have become more and more common today, due to both the aging population and the ever-expanding sports community. However, a new therapeutic technology called photobiomodulation (PBM) is giving hope to thousands of individuals in need. Traumatic brain injury (TBI), dementia, post traumatic stress (PTSD) and attention deficit (ADD) disorders are in many cases quickly and safely improved by PBM. PBM employs red or near-infrared (NIR) light (600 - 1100 nm) to stimulate healing, protect tissue from dying, increase mitochondrial function, improve blood flow, and tissue oxygenation. PBM can also act to reduce edema, increase antioxidants, decrease inflammation, protect against apoptosis, and modulate the microglial activation state. All these effects can occur when light is delivered to the head, and can be beneficial in both acute and chronic brain conditions. Methods: In this case series, we used a high power, FDA-approved superpulsed laser system applied to the head to treat four chronic stroke patients. Patients received as few as three 6 - 9 minute treatments over a one-week period. The follow up time varied, but in one case was two years. Results: Patients showed significant improvement in their speech and verbal skills. Improvements were also noticed in walking ability, limb movement, less numbness, and better vision. Conclusion: The use of PBM in stroke rehabilitation deserves to be tested in controlled clinical trials, because this common condition has no approved pharmaceutical treatment at present.

We perform benchmark calculations of the p-wave resonances in the exponentially cosine screened Coulomb potential using the uniform complex-scaling generalized pseudo-spectral method. The present results show significant improvement in calculation accuracy compared to previous predictions and correct the misidentification of resonance electron configuration in previous works. It is found that the resonance states approximately follow an n2-scaling law which is similar to the bound counterparts. The birth of a new resonance would distort the trajectory of an adjacent higher-lying resonance.

Traumatic brain injury is a major health concern worldwide with massive financial and social impact. Conventional treatments primarily focus on the prevention of further damage to the brain parenchyma, while failing to address the already existent symptoms. Previous clinical studies have shown that Low Level Laser Therapy (LLLT) can significantly reduce pain and induce temporary vasodilation in capillaries, which the authors hypothesize can be used to improve the quality of life in TBI patients by treating their current symptoms, which are predominately migraine-like headaches. This case report illustrates the use of LLLT in the treatment of a patient with a TBI and the great clinical success achieved in the reduction of pain, as measured by VAS—achievable within five treatments of 10 minutes in duration.
