Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a single site, pilot randomized, double blinded control trial designed to assess changes in cognitive symptoms in cancer survivors with cancer-related cognitive impairment. Patients will be randomized into one of two Arms: Intervention or Control.

* Arm A: Intervention Group: Use of the THOR LED Photobiomodulation helmet 3x per week for 6 weeks. Helmet will be in 'therapeutic setting', 35mW/cm2 = 42J/cm2
* Arm B: Control Group: Use of the THOR LED Photobiomodulation helmet 3x per week for 6 weeks. Helmet will be in 'placebo setting', 0mW/cm2 = 0J/cm2

This study has been designed to assess the hypothesis that Photobiomodulation can have a positive impact on cognitive symptoms in cancer survivors with cancer-related cognitive impairment.

30 participants will be recruited for this study, 15 per group. Self-report questionnaires assessing cognitive concerns, cognitive abilities, quality of life, depression, and anxiety will be administered at three timepoints through the study Baseline, End of Study Visit and 1 Month Follow Up

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention Arm - Therapeutic Setting

Photobiomodulation Helmet, Therapeutic setting, 35mW/cm2 = 42J/cm2, 3 x Sessions per week for 6 weeks

Group Type EXPERIMENTAL

THOR LED Photobiomodulation Helmet - Therapeutic

Intervention Type DEVICE

Photobiomodulation (PBM) is a non-invasive treatment option that uses nonionizing light sources such as laser diodes and light-emitting diodes in the visible and near-infrared spectrum.

Each participant will be required to sit with the helmet device over their head for the length of their study session. Participants and study staff will wear protective goggles throughout each session. These goggles help to block out any red LED light emitted from the helmet device. Participants may experience a pleasant warmth upon their head during both the therapeutic and control settings.

Helmet will be in 'therapeutic setting' of 35mW/cm2 = 42J/cm2

Control Arm - Non-Therapeutic Setting

Photobiomodulation Helmet, Non-Therapeutic setting, 0mW/cm cm2 = 0J/cm2, 3 x Sessions per week for 6 weeks

Group Type SHAM_COMPARATOR

THOR LED Photobiomodulation Helmet - Control

Intervention Type DEVICE

Each participant will be required to sit with the helmet device over their head for the length of their study session. Participants and study staff will wear protective goggles throughout each session. These goggles help to block out any red LED light emitted from the helmet device. Participants may experience a pleasant warmth upon their head during both the therapeutic and control settings.

Helmet will be in 'non-therapeutic setting' of 0mW/cm2 = 0J/cm2
