Research on the effects of LED light therapy, also known as photobiomodulation, on autistic children is still in its early stages, but there are several promising findings:
Positive Outcomes:
- Reduced Autism Severity: Some studies have shown a reduction in the severity of autism symptoms, including improvements in social interaction, communication, and repetitive behaviours.
- Improved Cognition and Behaviour: Research suggests potential improvements in cognitive function, attention, and sleep quality, as well as a reduction in hyperactivity and noncompliant behaviour.
- Decreased Parental Stress: Positive changes in a child’s behaviour and functioning can lead to reduced stress levels for parents and caregivers.
- Reduced Autism Severity: Some studies have shown a reduction in the severity of autism symptoms, including improvements in social interaction, communication, and repetitive behaviours.
Additional Considerations:
- Varied Methodologies: The specific types of LED light therapy used, treatment durations, and study populations have varied across research, making it difficult to draw definitive conclusions.
- Limited Sample Sizes: Many studies have involved relatively small numbers of participants, which can limit the generalizability of findings.
- Further Research Needed: More rigorous, large-scale studies are necessary to confirm the efficacy and safety of LED light therapy for autistic children and to determine the optimal treatment protocols.
- Varied Methodologies: The specific types of LED light therapy used, treatment durations, and study populations have varied across research, making it difficult to draw definitive conclusions.
Specific Studies:
Several studies have shown positive results, such as:
- An 8-week open-label study published in the journal Photobiomodulation, Photomedicine, and Laser Surgery found that transcranial LED therapy (830 nm) applied to the forehead twice a week significantly reduced autism symptoms in adults.
- A study published in the Journal of Autism and Developmental Disorders showed that red light therapy applied to the brain reduced irritability, lethargy, and social withdrawal in children and adolescents with autism in just five sessions.

Red Light Therapy for Autism Symptoms in Children and Adolescents:
This study, published in the Journal of Autism and Developmental Disorders, examined the impact of red light therapy applied to the brain in children and adolescents with autism. After just five sessions, researchers observed significant reductions in irritability, lethargy, and social withdrawal.

Non-invasive Light Therapy for Autistic Children:
While the existing research suggests that LED light therapy may be a promising intervention for autistic children, it’s important to consult with healthcare professionals to discuss the potential benefits and risks for individual cases. As research progresses, we can expect a clearer picture of the effectiveness and appropriate use of this therapy for autism.
