About this study

Official title: Assessing Feasibility of Prolonged Repetitive Near Infrared Light Stimulation on Cognitive and Behavioral Symptoms in Early to Mid-Stage Dementia

This study will gather data to see if infrared and near infrared light frequency can increase the activity of brain cells and provide support for the cell's ability to repair and protect themselves against further damage.

Read the detailed description

Research suggests that impaired regional cerebral blood flow (rCBF) [flow of blood in certain parts of the brain] plays an important role in dementia. Infrared and near infrared light frequency has been shown to increase the activity of brain cells and provide support for the cell's ability to repair and protect themselves against further damage. This study will evaluate the effects of repeated brief exposure to near infrared light stimulation twice a day on subjects that have problems such as attention span, working memory, strategies of learning and remembering, planning, organizing, self-monitoring, inhibition and flexible thinking for an 8 week period.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • HelmetDevice

    Also called Photobiomodulation device

    The portable device covers the head and weighs about 3.5 lb., and is made of light-weight, durable plastic, it is placed on the head with eye panels facing forward. Elastic straps holding the arrays together easily expand to conform to each subjects' head. Patients may notice slight warming of scalp after usage. This warming effect is similar to wearing a regular motorcycle helmet for a similar duration.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Memory Score

    Mini Mental State Exam will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks). This quick assessment will be able to score assessed individuals using 0-30 scoring range. Collected scores will be compared at different time points and any numerical change in score will be evaluated.

    Measured: Before first treatment, at 4 weeks and then at 8 weeks.

  2. Alzheimer's Disease Assessment Scale-Cognitive Subscale (ADAS-Cog test) test

    ADAS-Cog test will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks) to measure cognition. This comprehensive test will measure patient's ability of language and memory. Test consist of 11 parts and will help to assess baseline and determine cognitive change over period of treatment using patient's ability to answer questions and given score.

    Measured: Before first treatment, at 4 weeks and then at 8 weeks.

  3. Quantitative Electro Encephalography (QEEG)

    QEEG measurement will be performed in beginning of the study (before first treatment), in the middle of the treatment (in 4 weeks) and in the end of treatment (in the end of 8 weeks). This measurement will use modern analytic software to process activity of the brain during cognitive task in the forms of electrical signals received from the surface of the scalp. Analytical software uses algorithms to assess recorded brain impulses and evaluate brain function, helping to track changes in the brain function due to treatment.

    Waveforms of EEG being assessed:

    1. Delta frequencies (1-4 HZ) are produced during sleep are widespread in the frontal central region. Delta is necessary for sleep and stillness.
    2. Theta frequencies (4-8 HZ) are associated with selective attention, retrieving newly learned information, and preceding sleep. Theta aids creativity and problem solving.
    3. Alpha frequencies (8-12 HZ) appear in the posterior when the eyes are closed. It is associated with idling and

    Measured: Before first treatment, at 4 weeks and then at 8 weeks.

Questions about this trial

What is this clinical trial studying?

A study testing Helmet in people with Mild to Moderate Dementia, run by Baylor Research Institute at 2 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: under way, not looking for participants, as of the sponsor's last update on 11 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Memory Score (time frame: Before first treatment, at 4 weeks and then at 8 weeks.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2026.
