810 Transcranial Photobiomodulation for the Treatment of Children with Autism Spectrum Disorder (ASD): A Retrospective Study

Summary of Key Findings

• Background:Autism Spectrum Disorder (ASD) is characterized by deficits in social communication and restricted, repetitive patterns of behavior.Currently, there are no pharmacological treatments for the core symptoms of ASD.This retrospective study investigated the efficacy of Transcranial Photobiomodulation (tPBM)—using near-infrared light—as a non-invasive neuromodulation intervention for children with ASD.

  • This retrospective study investigated the efficacy of Transcranial Photobiomodulation (tPBM)—using near-infrared light—as a non-invasive neuromodulation intervention for children with ASD.
• Mechanism:Brain Oscillation Modulation: The study used two specific protocols (Alpha and Gamma) to modulate corresponding brain wave bands.Cellular Energy & Blood Flow: tPBM delivers near-infrared light to the brain, which is absorbed by mitochondrial enzymes (cytochrome c oxidase), increasing ATP production and improving regional cerebral blood flow.Neuroplasticity: It is thought to reduce neuroinflammation and promote synaptic plasticity, helping to "re-tune" the neural circuits that are dysfunctional in ASD.

• Clinical Results:Reduced Severity: Significant reduction in ASD severity scores was observed (CARS scores, p < 0.001) over the 6-month treatment period.Behavioral Improvement: A relevant decrease in noncompliant/disruptive behaviors and behavioral rigidity (MERS-R scores) was reported.Cognitive & Life Quality: Patients showed improvements in attentional functions and sleep quality (PSQI).Family Impact: Parents reported a significant reduction in parenting stress (APSI scores).

• Conclusion:Transcranial Photobiomodulation (tPBM) is a promising, safe, and effective at-home intervention for improving the core and associated symptoms of Autism Spectrum Disorder.It offers a new non-pharmacological direction for enhancing social function, reducing rigidity, and improving the overall quality of life for children with ASD and their families.
