Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that affects approximately 6% of children and 2.5% of adults worldwide.
ADHD is believed to be related to neurotransmitter imbalances, particularly in dopamine, norepinephrine, and serotonin levels in the brain. Lower dopamine levels may affect focus and task completion, and genetic variations in dopamine transporter proteins could result in too much dopamine being removed too quickly from the brain.
Additionally, ADHD has been associated with changes in functional connectivity in various brain networks, including the default mode network, visual, sensory motor, attentional, frontal, central executive, and frontal networks.
There is some evidence that light therapy may be an effective treatment for ADHD.
In this study, the researchers investigated the potential of morning bright light therapy as a 3-week treatment for 29 adults with attention-deficit/hyperactivity disorder (ADHD). The results showed a significant decrease in ADHD symptoms, improved mood symptoms, and a phase advance in circadian preference.
Another study by Stephan, W. et al. (2022) found that tPBM reduced neuroinflammation, increased cerebral blood flow, reduced oxidative stress, and stimulated neuroplasticity and synaptogenesis, which consequently resulted in greater ability to focus, organize, and manage ADHD symptoms in adults. These findings suggest that tPBM may be a safe and effective treatment option for ADHD.
