More Info

Transcranial Infrared Laser Stimulation (TILS) is the use of infrared on brain regions to decrease decline and improve brain health.

1064 nm, 250 mW/cm^2 irradiance has already been shown to increase cognitive function when applied to right prefrontal cortex in young adults.

This study tested older adults at risk for cognitive decline due to circumstances including traumatic brain injury and carotid artery thickness.

Testing included the use of EEG, MRI, and standardized tests.

Treatment targeted the right prefrontal cortext, which has the strongest relationship between carotid clog and working memory performance. Treatment location extended 4 cm medial and 4 cm lateral to FP2 point (10-20 EEG placement).

The laser stimulation alternated each minute between medial and lateral sites.

Each site received 4 minutes during an 8 minute session.

Treatment schedule: 1/week/5 weeks.

There were no side effects.

All subjects improved:

  • increased resting state alpha, beta, and gamma power
  • more efficient prefrontal blood-oxygen level
  • memory and cognition test scores
