The standard 1 minute each lobe 3 times per week for 4 weeks is a good start and re-evaluate to determine protocol moving forward. If you have rental laser program in your office that is ideal. The patient can perform 1-3 times per day.
Note: In a PubMed article using the Hz of 40 (infra-red and intranasal), the research showed benefits for those suffering from Alzheimer's to the settings they tested under study parameters.
Sci Rep. 2019 Apr 19;9(1):6309. doi: 10.1038/s41598-019-42693-Pulsed Near Infrared Transcranial and Intranasal Photobiomodulation Significantly Modulates Neural Oscillations: a pilot exploratory study. - PubMed - NCBI
My explanation to the reader for this success is Alzheimer's (neurodegeneration) creates a slow brain. Forty Hz is a high Beta wave (19 Hz - 40 Hz) and relatively low Gamma wave (25 - 100 Hz). The reader and treating clinician may find this useful to apply 40 Hz specific or a variation within ranges for treatment. The Erchonia laser has shown significant physiological benefit deep within the brain while lasering on the outer cranium. A 635 nm laser has a significantly more energy transfer (electron volts), per photon to the treated tissue, over longer wavelengths. Especially compared to the infra-red range (761 nm and greater is the infra-red range).
Alzheimer's and ALL neurodegenerative conditions lack neurological firing in the body. Use or lose it speeds up the disease. Vibration therapy using the VibePlate specifically for unattended "Active Unattended Laser Therapy" and to increase neural drive is fantastic!!!! The RPM can be set to mirror your laser settings from 10 - 60.
