More Info

Vielight administered transcranial and intranasal 810 nm to Alzheimer’s patients for 12 weeks.

Tests at 6 and 12 weeks showed significant improvements in Vielight group over controls. Tests included:

  • Alzheimer’s Disease Assessment Scale-cognitive
  • Neuropsychiatric Inventory (NPI)
  • MRI

Results included:

  • increased cerebral perfusion
  • increased connectivity between the posterior cingulate cortex and lateral parietal nodes within the default-mode network

There were no side effects.

Treatment dose data comes from a subsequent study using the same criteria. Unfortunately it did not include the lower back dosage.

810 intranasal: 810 nm, 14.2 mW/cm^2, 10 Hz pulse, 10.65 J/cm^2 per nostril
neuro transcranial, intranasal: 810 nm,  41 mW/cm^2 transcranial, 23 mW/cm^2 intranasal, 10 Hz pulse, 24.6 and 13.8 J/cm^2

My calculations from that data:

week 1, “810” device, 25 minutes, intranasal 810 nm, 14.2 mW/cm^2, 10.65 J/cm^2 per nostril

week 2, “neuro” device, 25 minutes, intranasal 810 nm pulzed at 10 Hz, 23 mW/cm^2, 17.25 J/cm^2 per nostril; 25 minutes transcranial 810 nm pulsed at 10 Hz, 41 mW/cm^2, 61.5 J/cm^2 delivered to scalp, estimated to reach  40 mm depth

Intransal irradiance week 1, 14.2 mW/cm^2; week 2: 23 mW/cm^2; transcranial irradiance week 2: 41 mW/cm^2

week 1 intranasal 10.65 J/cm^2 per nostril; week 2, intranasal 17.25 J/cm^2 per nostril; week 2 transcranial, 61.5 J/cm^2 to scalp estimated to reach 40 mm depth
