Brief Summary:
This is a mechanism-driven translational project to test the efficacy of transcranial low-level light/laser therapy (LLLT), for enhancing cognitive function in middle-aged and older adults and participants with Mild Cognitive Impairment.

Condition or disease Intervention/treatment Phase
Healthy Participants Mild Cognitive Impairment Device: LLLT Device: Placebo Phase 2

Detailed Description:
The goal of this project is to test the efficacy of LLLT to enhance neurocognitive function in middle-aged adults and examine the modulating influences of carotid atherosclerosis. The specific aims will be accomplished in a randomized controlled trial (RCT) by examining cognitive test performance and blood oxygen level-dependent (BOLD) response to a working memory task in middle-aged and older adults and participants with Mild Cognitive Impairment pre- and post- six-week long intervention of LLLT or placebo. In addition, the investigators will examine if carotid artery intima-media thickness (IMT) moderates the therapeutic effects of LLLT.

Arm Intervention/treatment
Experimental: LLLT
Six weekly sessions of LLLT. The treatment will consist of applying light of a specific wavelength (1064 nm) using a laser diode supplied by Cell Gen Therapeutics, LLC (CG-5000 laser, HD Laser Center, Dallas, TX, USA). Each laser stimulation session will consist of total 8 min, with eight 1 min/cycle treatments alternating between two locations on the right forehead.
Device: LLLT
The treatment will consist of applying light of a specific wavelength (1064 nm) using a laser diode supplied by Cell Gen Therapeutics, LLC (CG-5000 laser, HD Laser Center, Dallas, TX, USA).

Active Comparator: Placebo
The control group will undergo the same procedure as the treatment group, but will receive brief (5-s) stimulation to the intended site on the forehead, followed by 55 s of no stimulation, for each 1-min cycle. Thus the control group will receive approximately 1/12th of the cumulative energy density as the treatment group. This is sufficient to provide a brief sensation of slight heat (as active placebo) at the onset of each one-minute cycle, using a fraction of the energy received by the experimental group.
Device: Placebo
The treatment will consist of applying light of a specific wavelength (1064 nm) using a laser diode supplied by Cell Gen Therapeutics, LLC (CG-5000 laser, HD Laser Center, Dallas, TX, USA). However, the placebo group will receive approximately 1/12th of the cumulative energy density as the treatment group.
