Vielight Brain Lights


When dementia red light therapy devices become the norm, we will hold up Vielight as the breakthrough device that led the way.

Use the Vielight Neuro as the yardstick by which all other dementia and brain injury red light therapy devices are measured.

Vielight is the most well-tested brain red light therapy you can buy.

The Vielight Duo combines the Alpha and Gamma models into one combination unit. 

Learn whether you need the Alpha, Gamma, or Duo in this Vielight Neuro Red Light Therapy review.

  • For Alzheimer’s and other neurodegenerative diseases: Neuro Gamma
  • For Brain Injury: Neuro Alpha
  • For Biohackers (brain health and longevity): Neuro Duo combined with X-Plus





Red light therapy is not a cure, but it does significantly reduce memory loss, anxiety, irritability, and the severity of other dementia and brain injury symptoms.

How to Choose the Duo, the Alpha, or the Gamma

Which Vielight to get depends on the problem you want to solve. For some people, it also depends on whether you are sensitive to the 40 Hz pulsation.

Here’s an easy way to decide which Vielight to get.

  • Brain Injury and Sundowning: Get the Neuro Alpha
  • Parkinson’s, Huntington’s, Alzheimer’s, and other dementias: Get the Neuro Gamma

For Dementia

Get the Vielight Gamma for dementia from Alzheimer’s, Parkinson’s, and Huntington’s, as well as for mild cognitive impairment (MCI).

In studies of the Gamma’s effects on dementia symptoms, the Vielight Neuro Gamma significantly decreased memory loss and emotional issues such as depression and anxiety.

Vielight recommends the Gamma for this population.

For Brain Injury

Get the Vielight Alpha for traumatic brain injury (TBI), chronic traumatic encephalopathy (CTE), and concussion, as well as for sundowning symptoms from Alzheimer’s.

In studies on the effect of red light therapy on brain injury, patients did significantly better on cognitive tests and sleep health using the Vielight Alpha.

Depression and anxiety scores fells as well.

What About the Neuro Duo?

Vielight recommends the Gamma for dementia because the 40 Hz pulsation address brainwave abnormalities common in dementia brains.

They recommend the 10 Hz Alpha device for brain injury because the slower pulsation works better for people who are sensitive to light changes.

There will be some people for whom the 40 Hz is recommended but they will also do well with the 10 Hz.

Likewise, some people will get the 10 Hz Alpha but would have done well with the 40 Hz  Gamma.

To cover all the bases, get the Neuro Duo device to get the 10 Hz and 40 Hz pulsation in one device.

Treatment Schedule

Alpha 10 Hz pulsation often makes the user sleepy, so use this treatment in the afternoon or evening. 40 Hz can be energizing, so use this treatment in the morning.

Dementia and Brain Injury Science using the Vielight Neuro

Vielight is a therapeutic device that has been clinically proven to reduce the severity of dementia symptoms.

Vielight emits a gentle light therapy that helps improve brain function and overall well-being.

Vielight uses precision light therapy to stimulate the brain’s “Default Mode Network,” improving cognitive function and reducing agitation.

Vielight has been found to improve increase socialization, and stimulate memory recall in patients with dementia.

Vielight is a safe and effective treatment that can be used in the home or care facility.

The Gulf War Illness Study

Researchers tested the effects of the Vielight Neuro Alpha on Gulf War Illness (GWI) symptoms.

GWI symptoms overlap dementia and brain injury complaints, including those of:

  1. persistent headaches
  2. cognitive difficulties
  3. joint pain
  4. musculoskeletal pain
  5. fatigue
  6. gastrointestinal probelms
  7. Post Traumatic Stress Disorder (PTSD)

Because the pattern can present in non-Gulf War veterans, the phenomenon is also called Chronic Multisymptom Illness (CMI).

A CMI diagnosis is 6 months of symptoms in at least two of these categories:

  1. fatigue
  2. pain
  3. cognitive-mood disorders

A Kansas GWI/CMI is moderately severe or has multiple chronic symptoms in at least three of these categories:

  1. fatigue/sleep
  2. pain
  3. neurological/cognitive/mood
  4. respiratory
  5. gastrointestinal
  6. skin

In this study, subjects took self-assessment questionnaires and cognitive tests. They tested before treatment and at the 12-week mark.

Patients 1 and 2 presented with Kansas GWI/CMI. They used the Vielight Neuro Alpha daily for 12 weeks.

At 12 weeks both subjects improved on multiple scores.

Patient 1 no longer qualified as having Kansas GWI/CMI. His diagnosis was reduced to mild-moderate CMI. Patient 1 showed improvements on the mood-cognitive, pain, sleep, and fatigue scales.

Patient 2 no longer qualified for his diagnosis of severe Kansas CMI. His diagnosis was reduced to mild-moderate CMI. He showed improvements in fatigue, pain, and mood-cognitive scores.

The Parkinson’s Disease Vielight Study

In this study, Parkinson’s patients received Vielight Gamma treatment for various scheduled periods over a span of 40 weeks. Participants had significant improvement in these scores:

  • functional mobility
  • dynamic balance
  • cognition

They had improvements (but that were not statistically significant) in the fine motor skills and static balance tests.

The Major Depressive Infrared Study

In a study using a device with the same wavelength as the Vielight Neuro but without pulsation, patients with Major Depressive Disorder received transcranial (head) infrared therapy for six weeks.

At the study’s end, these patients score significantly higher on 17 points of the Hamilton Depressive scale.

The Depression and Anxiety Red Light Therapy Study

In another study using the same wavelength as the Vielight Neuro and again without pulsation, patients with depression and anxiety felt significant relief after four weeks of red light therapy.

In this study, the researchers did not find changes in cerebral blood flow, which was a rare finding as most red light therapy studies show a strong increase in blood flow and oxygenation to the brain.

The Dementia Case Series Vielight Study

In a 2017 study published in Photomedicine and Laser Surgery, dementia patients treated with the Vielight Alpha obtained significant gains after 12 weeks of treatment.

Currently, Vielight recommends the Gamma for dementia patients, but in 2017, they were testing the Alpha on this population.

That they had significant gains with the Alpha shows that both the Alpha and the Gamma devices have positive effects on dementia symptoms.

Dr. Chao reported in this study that medical imaging also showed neural improvements.

The light reached the “bilateral mesial prefrontal cortex, precuneus/posterior cingulate cortex, angular gyrus, and hippocampus,” she reported in this study.

Study results included improvements in:

  • faster time falling asleep
  • more hours staying asleep
  • fewer angry outbursts
  • reduced anxiety
  • reduced instances of wandering

The Brain Injury Red/Infrared Study

Researchers tested red and infrared light therapy on brain injury patients who experienced post-traumatic stress disorder (PTSD) from the accidents that caused the brain injuries.

This study tested the 633 nm red and 870 nm infrared.

The Neuro outputs 810 nm infrared, so this is not an apples-to-apples comparison.

However, it does substantiate reports that the Vielight has the effects because researchers used similar (but not exactly the same) wavelengths on the brain injury population and got results similar to those reported from using the Neuro.

In this study, the patients obtained significantly better sleep, decreased symptoms of PTSD, and improved social performance.


Studies on red and infrared light applied in sufficient but not too much quantity to the head show that this therapy obtains significant improvements at emotional, cognitive, and physical levels.

The Vielight Neuro Duo offers the Alpha and Gamma models in one device.

Although Vielight suggests that brain injury patients use the Alpha, and dementia patients use the Gamma, there is a good possibility that both populations will benefit from both devices, justifying the Duo purchase over the Alpha or Gamma alone.

Families sharing a device will also benefit from the two pulsation options.

To make this simple, get the Alpha for brain injury or sundowning, or get the Gamma for the rest of the dementia symptom set.

To make it comprehensive, get the Duo combining the Alpha and Gamma into one device. Use the Gamma setting in the morning to energize, and use the Alpha setting in the evening to relax.
