weird, I will check it. Maybe it has a character limit and is cutting off the last part of the link. back in 5.

 Nope I just messed it up somehow, it should be page 2, this worked on my computer when I copied and pasted it, but it might be re-accessing a stored link. Please let me know if it still doesn't work.

To be fair, this is an open label trial for people with mild traumatic Brain Injury, not Alzheimer's.



All Principal Investigators ARE employed by the organization sponsoring the study.

Its called

Effects of LEDs on Memory in TBI Patients (LED)

its by Ross D Zafonte at the Spaulding Rehabilitation Hospital


Over a period of 2 years 11 participants were studied with no adverse events

Population was Males and Females, ages 18 to 65 years who sustained a mild traumatic brain injury at least 6 months prior to study participation. All study subjects received treatment during 6-Week period (3x per week) for a total of 18 Transcranial LED Treatments using the MedX Health Phototherapy (light and laser). Each session was 30 minutes in duration

Two former football players with Traumatic Brain Injuries took part in the testing, both purchased the device after the trial ended.


This invited paper reviews our research with scalp application of red/near-infrared (NIR) light-emitting diodes (LED) to improve cognition in chronic, traumatic brain injury 1.

 Application of red/NIR light improves mitochondrial function (especially hypoxic/compromised cells) promoting increased ATP, important for cellular metabolism.

 Nitric oxide is released locally, increasing regional cerebral blood flow. Eleven chronic, mTBI participants with closed-head injury and cognitive dysfunction received 18 outpatient treatments (MWF, 6 Wks) starting at 10 Mo. to 8 Yr. post-mTBI (MVA, sports-related, IED blast injury).

 LED therapy is non-invasive, painless, non-thermal (FDA-cleared, non-significant risk device). Each LED cluster head (2.1" diameter, 500mW, 22.2mW/cm2) was applied 10 min (13J/cm2) to 11 scalp placements: midline, from front-to-back hairline; and bilaterally on dorsolateral prefrontal cortex, temporal, and parietal areas.

 Testing performed pre- And post-LED (+1 Wk, 1 and 2 Mo post- 18th treatment) showed significant linear trend for LED effect over time, on improved executive function and verbal memory.

 Fewer PTSD symptoms were reported.

 New studies at VA Boston include TBI patients treated with transcranial LED (26J/cm2); or treated with only intranasal red, 633nm and NIR, 810nm diodes placed into the nostrils (25 min, 6.5mW, 11.4J/cm2).

 Intranasal LEDs are hypothesized to deliver photons to hippocampus. Results are similar to Naeser et al. (2014).

 Actigraphy sleep data show increased sleep time (average, +1 Hr/night) post- 18th transcranial or intranasal LED treatment. LED treatments may be self-administered at home (Naeser et al., 2011).

 A shamcontrolled study with Gulf War Illness Veterans is underway.
