Alzheimer’s Vielight 810 nm Red Light Dose

Intranasal and transcranial application of 810 nm improved memory, cognition and MRI results in Alzheimer’s patients.

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
