Photobiomodulation and Alzheimer’s Disease: Key Points from the Review
Highlights Alzheimer’s disease (AD) is the leading cause of dementia worldwide, and there is still no cure capable of stopping its progression. Traditional amyloid-focused drug strategies have shown limited cognitive benefit, shifting attention toward multifactorial disease mechanisms. Photobiomodulation (PBM) emerges as a multi-target, non-invasive approach acting on mitochondria, inflammation, blood flow, and waste clearance. Early […]
Dose-Dependent Safety and Tolerability of Transcranial Photobiomodulation
Highlights Well tolerated at multiple settings: Participants tolerated low, medium, and high tPBM settings well. Side effects similar to sham: Reported symptoms were comparable to the “placebo” session. No meaningful vital sign changes: Blood pressure and body weight remained stable. Why it matters: Supports tPBM as a low-risk, non-invasive approach worth continued clinical research. […]
Can Light Therapy Ease Autism Symptoms in Young Children?
Highlights A randomized, sham-controlled pilot trial tested whether pulsed near-infrared transcranial photobiomodulation (tPBM) could support symptoms in children with autism ages 2–6. Children received twice-weekly sessions for 8 weeks (about 20 minutes per session) using 850 nm light pulsed at 40 Hz. The active group showed a greater reduction in autism symptom severity on a […]
A New Beam of Hope for Parkinson’s: How Light Therapy May Ease Symptoms
Highlights Parkinson’s disease (PD) affects more than 10 million people worldwide, causing tremor, stiffness, slowed movement, balance problems, and cognitive decline. A proof of concept clinical study by Liebert et al. (2021) investigated whether PBM could safely improve motor and cognitive symptoms in people with PD. The findings were encouraging: PBM was well tolerated with […]
Lighting the Way: How Red Light Therapy May Help Treat Diabetic Macular Edema?
Highlights Diabetic macular edema (DME) is a major cause of vision loss in diabetes and is driven by retinal fluid leakage. Shen et al. (2020) explored whether photobiomodulation (PBM) — low-intensity red light (670 nm) — could help reduce retinal swelling. The results were encouraging: central macular thickness decreased, especially at higher doses, and effects […]
Can Light Therapy Help Improve Brain Function in Dementia?
Highlights Dementia affects millions of people worldwide and is a leading cause of disability in older adults. The aim of the study was to investigate whether regular transcranial and intranasal photobiomodulation could improve cognition, behavior, cerebral blood flow, and brain network connectivity in people with dementia. Those who received PBM showed clear improvements compared to […]
Can Light Therapy Help Heal the Brain After Injury? A New Hope?
Highlights Traumatic brain injury (TBI) is a leading cause of disability and affects thousands of people every year A recent case series by Rindner et al. (2022) explored an innovative approach: transcranial infrared laser stimulation (TILS), a form of photobiomodulation that uses gentle near infrared light to stimulate the brain’s natural healing processes. The results […]
Can Light Therapy Help Manage Arthritis Symptoms?
Highlights Arthritis is a leading cause of long-term pain, stiffness, and reduced mobility. Many people look for non-drug, non-invasive options that can be used alongside standard care. Photobiomodulation (PBM) — also called red/near-infrared light therapy — is being studied as a supportive approach for arthritis-related symptoms. Research suggests PBM may influence inflammation, pain signaling, circulation, […]
Can Red or Infrared Laser Increase ATP? An Overview of the Literature
Highlights Red and near-infrared PBM consistently influence mitochondrial ATP production. Cytochrome c oxidase and ATP synthase are key photobiological targets. ATP increases depend on wavelength, fluence, pulse structure, and tissue type. Both in vitro and in vivo models demonstrate ATP enhancement. Non-thermal mechanisms predominate. Background ATP synthesis is central to PBM’s biological effects. Numerous […]
Green Laser Photobiomodulation and Mitochondrial Function
Highlights Green laser PBM (≈505–532 nm) has been widely studied, but mostly in ablative or photocoagulative contexts. Evidence for direct activation of mitochondrial ETC complexes by green light remains limited. Green laser PBM may exert indirect mitochondrial effects via membrane potential, calcium signaling, and redox modulation. Biological responses appear highly parameter- and context-dependent. Green laser […]
