Outcome Measures

Primary Outcomes (2)

  • Cerebral vasodilator function

    This will be assessed as the increase in blood flow in the middle cerebral artery during a hypercapnic stimulus

    Immediately before the start of the experimental or sham condition intervention. And immediately after the end of the experimental or sham condition intervention.

  • Neurocognitive function

    This will be assessed using the NIH Toolbox which is a battery that consists of several cognitive challenges.

    Immediately before the start of the experimental or sham condition intervention. And immediately after the end of the experimental or sham condition intervention.

Study Arms (2)

Transcranial Photobiomodulation

EXPERIMENTAL

Transcranial Photobiomodulation (tPBM) is a novel and non-invasive strategy that utilizes a helmet that delivers low-level laser therapy to activate intracellular enzymatic pathways leading to an increase in mitochondrial activity, cerebral oxygenation, and thus neural and overall brain function. Importantly, this approach improves cognitive function in various animal models and limited human populations. Furthermore, there is limited evidence to suggest that these neurocognitive improvements are in-part related to increases in cerebral blood flow and cerebral vascular function/health.

Device: Transcranial Photobiomodulation

Sham condition

PLACEBO COMPARATOR

In this condition the participants will wear the Transcranial Photobiomodulation (tPBM) headgear; however, no light will be delivered.

Device: Transcranial Photobiomodulation helmet (Neuradiant 1070 Plus) with no light administered

Interventions

The transcranial photobiomodulation will be delivered through the Neuradiant 1070 Plus-Programmable 4-Quadrant Photobiomodulation System. This is a commercially available helmet that will be purchased from a commercially available source.

Transcranial Photobiomodulation

In this condition the participants will wear the Transcranial Photobiomodulation helmet (Neuradiant 1070 Plus); however, the light will not be administered.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Both men and women between the ages of 18-80 and of any race/ethnicity will be included in this study.

You may not qualify if:

  • Abnormal results from the blood screening will not impact eligibility for the study.
  • Individuals with brain injuries/surgeries in a year before the study and individuals who can not provide consent on their own will be excluded from participation.
  • Pregnant subjects, women who are breast feeding, and children (i.e. younger than 18) will not be recruited for the study. This will be assessed via self-report.
  • If a subject has any allergies to spandex/lycra, the subject will be excluded. However, latex allergies are not contraindicated.
  • Individuals with cardiac pacemakers and/or implantable cardioverter defibrillators and individuals with epilepsy will be excluded.
