What is Photobiomodulation (PBM) and how is it Applied in Mental Health Treatment?

Photobiomodulation (PBM) therapy is an innovative approach in mental health care, gradually gaining recognition for its potential benefits in treating a variety of psychological conditions. At Lighthouse Psychiatry, a leading brain health center with locations in Gilbert and our new facility opening this month in Scottsdale, Arizona, we integrate PBM into our treatment options to provide advanced care for our patients.

Understanding Photobiomodulation (PBM)

Photobiomodulation refers to the use of red or near-infrared light to stimulate, heal, regenerate, and protect tissue that has either been injured, is degenerating, or else is at risk of dying. The light is typically produced by lasers or powerful LEDs and targets specific areas of the brain. PBM is known for its ability to decrease inflammation and pain and for increasing blood flow and tissue regeneration. It’s non-invasive, painless, and requires no recovery time, making it an appealing option for many patients.

PBM in Mental Health

In the context of mental health, PBM is explored for its effects on brain health, particularly in managing symptoms of depression, anxiety, and cognitive decline. The therapy is believed to enhance mitochondrial function in neurons, which can lead to improved energy production and potentially healthier brain function. This can result in improved mood, better cognitive abilities, and overall mental health.

At Lighthouse Psychiatry, serving as counselors in Gilbert and soon in Scottsdale, we apply PBM as part of a comprehensive treatment plan. Our psychiatrists in Gilbert, AZ, assess each patient’s individual needs to determine the most effective treatment strategies. This patient-centered approach ensures that all aspects of the individual’s health are addressed.

Our New Scottsdale Location

This month, we are excited to expand our services with a new location in Scottsdale, where we will continue to offer innovative treatments like PBM. The new facility will allow us to serve a broader community, providing cutting-edge mental health services to more individuals in need.

For anyone interested in exploring how Photobiomodulation can be part of their mental health treatment, our team at Lighthouse Psychiatry is ready to assist. We encourage you to contact our professional staff to learn more about how PBM and other therapies can benefit your mental health. Join us in Gilbert or Scottsdale and take a step forward in your journey to wellness.
