(2019) Evaluating the effect of the Vielight Neuro Gamma Device on real-time EEG signals in older adults at rest. (March 2017 – April 2019)


Published Study (Nature, Scientific Reports) : Link

Study Title
Evaluating the effect of the Vielight Neuro Gamma Device on real-time EEG signals in older adults at rest.

Study Objective
To evaluate whether the energy delivered by the Vielight Neuro Gamma produces a reliable effect on neural activity in older adults.

Double-blind, prospective, crossover.

Study Duration
Two session evaluation.

Study Site(s)
Vielight Inc. Office

Number of Subjects
Maximum of 20 older adults

Major Inclusion/Exclusion Criteria
• 60 years of age or older
• No current major psychiatric or neurologic disease
• No history of stroke or seizures
• All other medical conditions controlled by stable therap

Study Product and Planned Use
The experimental intervention will be the Vielight Neuro Gamma general wellness device. The device uses 5 light emitting diodes (810nm wavelength). Four diodes provide near-infrared energy transcranially, while the last does so intranasally, all targeting regions of the Default Mode Network. No significant heat is generated, allowing for a sham device which will be indistinguishable from the intervention to both the subjects and EEG technician. Devices will be utilized concurrently with EEG recording of subject at rest. The devices will be used in a randomized crossover design within the single study visit with the same EEG recordings to be obtained under both sham and active conditions.

Study Procedures
1. Informed Consent
2. Eligibility Assessment
3. First EEG Recording
4. One week washout period
5. Second EEG Recording

Primary Endpoint
Change from baseline in overall power spectral density between active and sham session.

Statistical Methodology
Repeated measures ANOVA with treatment as within subject measure.

2.1. Study Rationale & Background
Vielight Inc. has developed a novel general wellness device, called the Vielight Neuro Gamma, which delivers near infrared light through LEDs positioned over the skull and intranasally. This device is intended to enhance mental acuity as a general wellness device.

There are questions as to whether near infrared light is capable of penetrating the skull and/or nasal mucosa to reach and produce reliable effects in the brain.

Thus, Vielight Inc. wishes to utilize electroencephalography (EEG) as a method to measure, in real time, the effects of the Vielight Neuro Gamma on neural activity.

2.2. Study Device: Vielight Neuro Gamma
The Vielight Neuro Gamma device is a portable, wearable, low-level light delivery device that administers near-infrared light to the brain trans-cranially and intra-nasally and is intended to enhance mental acuity as part of general wellness. The device, shown below, consists of a controller (1), a Nasal Applicator (2), and a Head Set (3).

Figure 1. Vielight Neuro Gamma device
The Vielight Neuro Gamma delivers painless, non-invasive, non-thermal, non-laser, pulsed (40 Hz; 50% duty cycle), near-infrared light (810 nm wavelength) through 5 non-laser light emitting diodes (LEDs) over a 20 minute session. The device is powered by three rechargeable NiMH batteries. As shown below, one of the Vielight Neuro Gamma

LEDs is placed inside the nose for intranasal transmission of light energy and the remaining four LEDs are positioned over the skull for transcranial transmission.

Figure 2. Placement of Vielight Neuro Gamma device
2.3. Study Objective
In order to effectively test the capability of the Vielight Neuro Gamma to affect neural activity, EEGs using an active device must be compared to sham device EEGs in 20 subjects. This will allow us to reasonably calculate whether there is a significant difference in power spectral density as well as examine other relevant outcomes post-hoc.

• Study staff will place the saline-rinsed EEG electrode cap on the subject and may apply additional saline to individual electrode locations in order to ensure good conductivity
• Once the electrode cap is producing reliable readings, the subject will be asked to remain still and quiet with their eyes closed for an initial 10 min Rest-EEG recording
• At the completion of the 10 min recording, study staff will then place the Vielight Neuro Gamma device or Sham device on the subject, as shown in Figure 2 above.
• Study staff may then re-apply additional saline to individual electrode locations in order to ensure good conductivity
• Once the electrode cap is producing reliable readings, the subject will be asked again to remain still and quiet with their eyes closed for a 20 min Rest-EEG recording
• At the completion of the 20 min recording, study staff will then remove the Vielight Neuro Gamma device or Sham device and again re-apply additional saline to individual electrode locations in order to ensure good conductivity
• Once the electrode cap is producing reliable readings, the subject will be asked to remain still and quiet with their eyes closed for a final 10 min Rest-EEG recording

The second study visit will be a replication of Part C of the first visit. At the conclusion of the visit, the subject will be provided financial compensation of $100 CAD for the study.

5.1. Devices and Procedural Purposes
Device(s) being evaluated for effect on neural activity
Vielight Neuro Gamma

Quantitative EEG system with recording electrode cap
BrainMaster Discovery 20 System

5.2. Device Safety
Vielight Neuro Gamma: The controller houses three 1.5V NiMH batteries (1900 mAh each) and the controlling electronics for the Neuro Gamma. Both the Headset and Nasal Applicator are connected to the controller with connectors that prevent them from being incorrectly inserted. A single button initiates a software controlled 20-minute therapy – automatically timed but can be discontinued by pressing the button a second time. The maximum power output density to the nasal mucosa is 25 mW/cm2 with a 50% duty cycle (total energy delivered per session = 15 J). The maximum power output density to the scalp is 100 mW/cm2 with a 50% duty cycle for the posterior band LEDs and 100 mW/cm2 with a 50% duty cycle for the anterior band LED (total energy delivered per session = 225 J). All LEDs are well under the exposure limits established by IEC 62471:2006 – Photobiological safety of lamps and lamp systems..

BrainMaster Discovery 20 System: The BrainMaster Device does not produce any electro-magnetic fields and does not interfere with the operability of other devices. The unit is entirely powered by the USB interface, eliminating the need for batteries, while maintaining subject safety.

6.1. Planned Analysis
The primary endpoint for this study will be the change from baseline in overall power spectral density between active and sham session. To statistically determine a significant difference a repeated measures ANOVA with treatment as the within-subject measure will be utilized.

Additional exploratory analysis of a variety of measures obtained from the EEG recording will be conducted post-hoc.

6.2. Primary Endpoint Analysis: Sample Size Selection
The sample size of the study was chosen based on a review of the literature for exploratory EEG studies of novel neurotechnologies. Utilizing a sample size of 20 for this initial study will allow us to best estimate effects sizes of critical measures to be examined in follow-up confirmatory studies.

6.3. Eligibility of Subjects, Exclusions, Missing Data, and Removal of Subjects
All subjects responding to the advertisements are potential study candidates and will be screened for eligibility. Every effort will be made to ensure eligibility of the subjects prior to study enrollment. Subjects who do not meet all inclusion/exclusion criteria will not be enrolled or followed in the study. Subjects for whom no data was acquired due to technical failures or those that withdraw consent will be excluded from analysis. Subjects for whom only partial data was acquired will be included in all possible analysis.

7.1. Serious Adverse Events
A serious adverse event is any adverse event which occurs during the study visiti. is life threatening; orii. results in permanent impairment of a body function or permanent damage to a body structure; oriii. necessitates significant intervention, such as major surgery, to prevent permanent impairment of a body function or permanent damage to a body structure; oriv. requires hospitalization or an extended hospital stay; orv. results in moderate transient impairment of a body function or transient damage to a body structure; orvi. requires intervention, such as medication or cardioversion to prevent permanent impairment of a body function or damage to a body structure.Examples of serious adverse events include death, cardiac tamponade, myocardial infarction, stroke, and seizure.

7.2. Adverse Events
An adverse event is any adverse event that results in minimal transient impairment of a body function or damage to a body structure or which does not require any intervention other than monitoring. Examples of an adverse event include skin reaction or headache at the locations where the Vielight Neuro Gamma device makes contact with the subject’s skin.
A pre-existing condition should not be reported as an adverse event unless there has been a substantial change in severity that cannot be attributed to natural history.

7.3. Reporting
As this is a minimal-risk study, no serious adverse events are anticipated. However, any adverse events reported by subjects or observed by the study staff, during the course of the study visit procedures, will be recorded in the subjects CRF along with a brief description and any action taken. All adverse events determined by the principal investigator to be a potential result of study visit procedures, will be reported to the Institutional Review Board and the study sponsor.

(2015) Significant Improvement in Cognition in Mild to Moderately Severe Dementia Cases Treated with Transcranial Plus Intranasal Photobiomodulation: Case Series Report

[ Abstract Link (US National Library of Medicine) | Full Publication (Scientific Journal of Photomedicine and Laser Surgery) | Download Transcript ]
This study investigated whether patients with mild to moderately severe dementia or possible Alzheimer’s disease (AD) with Mini-Mental State Exam (MMSE) Baseline scores of 10-24 would improve when treated with near-infrared photobiomodulation (PBM) therapy.
There was significant improvement after 12 weeks of PBM (MMSE, p < 0.003; ADAS-cog, p < 0.023). Increased function, better sleep, fewer angry outbursts, less anxiety, and wandering were reported post-PBM. There were no negative side effects. Precipitous declines were observed during the follow-up no-treatment, 4-week period. This is the first completed PBM case series to report significant, cognitive improvement in mild to moderately severe dementia and possible AD cases.

The rights, safety and well-being of clinical investigation subjects shall be protected consistent with the ethical principles laid down in the Declaration of Helsinki. This shall be understood, observed and applied at every step in this clinical investigation.
It is expected that all parties will share in the responsibility for ethical conduct in accordance with their respective roles in the investigation. The Sponsor and the Investigator(s) shall avoid improper influence or inducement of the subject, monitor, the clinical investigator(s) or other parties participating in or contributing to the clinical investigation.
10.5.1 Protection of Subject Confidentiality
At all times throughout the clinical investigation, confidentiality will be observed by all parties involved. All data shall be secured against unauthorized access. Privacy and confidentiality of information about each subject shall be preserved in study reports and in any publication. Each subject participating in this study will be assigned a unique identifier. All CRFs will be tracked, evaluated, and stored using only this unique identifier.
The Investigator will maintain a confidential subject list identifying all enrolled subjects (Enrollment Log). This list will contain the assigned subject’s unique identifier and name. The Investigator bears responsibility for keeping this list confidential. This list will not be provided to the study sponsor and is only to be used at the study center.
Monitors and auditors will have access to the subject list and other personally identifying information of subjects to ensure that data reported in the CRF corresponds to the person who signed the ICF and the information contained in the original source documents. Such personal identifying information may include, but is not limited to the subject or caregiver’s name, address, date of birth, gender, race and medical record number.
Any source documents copied for monitoring purposes by the Sponsor will be identified by using the assigned subject’s unique identifier in an effort to protect subject confidentiality.
10.5.2 Ethics Committee/Institutional Review Board Approval
Institutional Review Board (IRB) / Research Ethics Board (REB) approval is required prior to study commencement. The Investigator must also work with sponsor personnel to obtain renewal of IRB/REB approval as dictated by local requirements during the entire duration of the study. The Investigator is responsible for fulfilling any conditions of approval imposed by the reviewing IRB/REB, such as regular reporting, study timing, etc. The Investigator will provide the study sponsor with copies of such reports.
10.5.3 Quality Assurance and Supervision by Authorities and Privacy
All documents and data shall be produced and maintained in such a way to assure control of documents and data to protect the subject’s privacy as far as reasonably practicable. The Sponsor and representatives of the regulatory authorities are permitted to inspect the study documents (e.g., study protocol, CRFs, and original study-relevant medical records/files) as needed. All attempts will be made to preserve subject confidentiality.
All clinical sites are subject to audit by study sponsor personnel or designee for protocol adherence, accuracy of CRFs and compliance with applicable regulations. Any evident pattern of non-compliance with respect to these standards will be cause for the site to be put on probation until appropriate corrective action is taken.

10.6 Final Report
A final report will be completed, even if the study is prematurely terminated. At the conclusion of the trial, an abstract reporting the results will be prepared and will be presented at a major meeting(s). A manuscript will also be prepared for publication in a reputable scientific journal.

10.7 Information Confidentiality
All information not previously published concerning the test device and research, including patent applications, manufacturing processes, basic scientific data, etc., is considered confidential and should remain the sole property of Vielight Inc. All information and data generated in association with this study will be held in strict confidence and remain the sole property of Vielight Inc. The Investigator agrees to use this information for the sole purpose of completing this study and for no other purpose without written consent from Vielight Inc.

10.8 Trial Registration
The study will be registered in a publicly accessible trial database ( prior to study initiation.
