Transcranial photobiomodulation is one of the most rapidly advancing areas in clinical neuroscience, and the evidence base supporting its use in complex neurological conditions has grown substantially over the past decade. For clinicians managing patients with chronic traumatic brain injury, post-traumatic stress disorder, traumatic encephalopathy syndrome, dementia, and post-stroke aphasia, photobiomodulation therapy offers a neurobiologically grounded, non-invasive approach to supporting cellular recovery, restoring functional network connectivity, and improving patient outcomes in cases where conventional options have reached their limits. This course brings that science directly into the clinical context, covering transcranial PBM protocols, near infrared light therapy, LED and laser parameters, and the neuroscience of key intrinsic brain networks including the default mode network and salience network.

The course translates published research, including neuroimaging data from functional connectivity MRI and resting state fMRI studies, into actionable clinical knowledge. Clinicians gain a precise understanding of how red and near infrared wavelengths interact with cytochrome c oxidase in mitochondria to restore ATP production in hypoxic and compromised neural tissue. They learn how the release of nitric oxide from mitochondria drives cerebrovascular dilation, promotes glymphatic drainage, and supports the conditions necessary for lasting neurological change. Treatment parameter selection, including joules per centimeter squared, power density, and placement targets for the mesial prefrontal cortex, anterior cingulate cortex, precuneus, and orbitofrontal cortex, is addressed with clinical precision rather than abstraction.

This course is designed for licensed clinicians who are already working with neurologically complex patients and want to add a scientifically rigorous, evidence-informed modality to their practice. It is particularly relevant for those managing chronic TBI sequelae, military veterans with blast-related PTSD, aging patients with progressive cognitive decline, former contact sport athletes presenting with traumatic encephalopathy syndrome, and post-stroke patients with aphasia or language impairment. One continuing education credit hour is awarded upon completion.
