New study alert! Near-infrared light therapy for autism

A recent study found that children ages 2–7 with autism who received near-infrared light therapy to the head for just 8 weeks showed meaningful improvements—including a 7-point drop in severity scores and measurable changes on EEG.

So what’s happening?

This therapy works on a biological level—not just behavioral. Near-infrared light penetrates the skull and is absorbed by mitochondria (specifically cytochrome c oxidase), helping boost ATP production. In simple terms: brain cells get more energy to communicate, regulate, and repair.

It may also help calm brain inflammation. Many children with autism show signs of neuroinflammation, and this light therapy appears to support glial cells (the brain’s immune system), reduce inflammatory markers, improve blood flow, and lower oxidative stress. The result? A more stable and connected neural environment—especially in areas like the default mode network (DMN), which is often dysregulated.

Here’s what researchers actually measured:

🧠 Decreased delta waves → linked to improved cognitive clarity and less “brain fog”

🧠 Increased beta & gamma waves → associated with attention, processing, and sensory integration

🧠 Real correlation → as brainwave patterns improved, clinical severity scores dropped too

And beyond the data, parents reported real-life changes—better sleep, more eye contact, improved speech, and stronger emotional regulation.

This is an exciting look at how supporting the brain at a cellular level can translate into meaningful, everyday improvements.
