Photobiomodulation for Memory Loss

This trial examines whether photobiomodulation (PBM) can assist individuals who feel their memory is declining, despite no medical diagnosis. PBM involves using special lights worn on the head, inserted in the nose, or placed on the neck to potentially improve mood and memory. The study will test three methods of using the lights and a sham version for comparison. Individuals concerned about memory decline, without a clinical diagnosis of dementia or other serious mental health conditions, may be suitable for this trial. Participants will use the device at home twice daily for five weeks. As an unphased trial, this study provides a unique opportunity to explore innovative treatments for memory concerns.

The trial does not specify if you need to stop taking your current medications. However, you cannot participate if you are currently using anti-coagulants or have had certain treatments like electroconvulsive therapy or ketamine recently.

Previous studies have shown that light therapy, known as photobiomodulation (PBM), is safe and easy to tolerate. Research indicates that using PBM on the head (transcranial PBM or tPBM) is practical and safe, even for daily home use. Participants reported no serious side effects and often experienced improvements in thinking and memory.

Using PBM through the nose (intranasal PBM or iPBM) also appears promising as a safe treatment. Studies found it improved memory and thinking skills in people with Alzheimer's disease, with no severe side effects noted.

For PBM targeting the vagus nerve (vagus nerve PBM or vPBM), studies suggest it is a safe and innovative way to enhance brain function and mood. No major negative effects were reported.

Researchers are excited about photobiomodulation (PBM) for memory loss because it offers a novel, non-invasive approach to potentially enhance cognitive function. Unlike traditional treatments for memory loss, which often involve medications targeting neurotransmitter activity, PBM uses light therapy applied to specific areas like the forehead, nasal passages, or vagus nerve. This method aims to stimulate cellular processes and improve brain health through light exposure, offering a different mechanism of action. The intrigue lies in its potential to provide benefits without the need for pharmaceuticals, reducing the risk of side effects commonly associated with medication.

Research has shown that light therapy, known as photobiomodulation (PBM), can improve brain function. This trial will explore different PBM applications: transcranial PBM (tPBM) on the forehead, intranasal PBM (iPBM), and vagal PBM (vPBM) targeting the vagus nerve. Studies have found that tPBM can enhance memory and overall brain performance in older adults. Specifically, iPBM has been linked to significant improvements in people with mild memory problems. Meanwhile, vPBM has shown positive effects on mood and thinking skills. These findings suggest that PBM might help improve memory and mood, making it a promising treatment for those experiencing mild cognitive issues.¹²⁴⁵⁶
