PRIMARY outcome

Timeframe: up to seven days after enrollment

Population: Subjects who completed light or sham treatment and at least one MRI scan. 43 patients completed the study with at least one MRI scan, 19 subjects in the Light treatment group and 24 subjects in the sham treatment group.

Number of subjects to successfully complete light therapy without serious unanticipated adverse events related to application of the device.

SECONDARY outcome

Timeframe: up to 3 months after treatment

Population: Of the 68 patients that were randomized, 28 completed at least one light therapy session. 43 patients completed the study with at least one MRI scan. 19 subjects in the light treatment group and 24 subjects in the sham treatment group. One MRI was deemed low quality and excluded from analysis (19 light treatment / 23 sham)

The presence of chronic white matter disease was evaluated using Fazekas scale. The scale divides the white matter in periventricular and deep white matter, and each region is given a grade depending on the size and confluence of lesions. periventricular white matter (PVWM). 0 = absent 1. = "caps" or pencil-thin lining 2. = smooth "halo" 3. = irregular periventricular signal extending into the deep white matter A neuroradiologist evaluated the 3D T2-SPACE-FLAIR images to detect the presence of T2 hyperintensities and their degree (0: absent; 1: mild; 2: moderate; and 3: severe) for PVWM. Higher values represent a worse outcome.

SECONDARY outcome

Timeframe: RPQ scores were collected at approx 72 hours, 14 days, 3 months, and 6 months and the mean was calculated for the values reported.

RPQ is a 16 item self-assessment questionnaire completed via an in-person or phone interview. Each item in the questionnaire is assessed on a 5-point scale ranging from 0 (no problem) - 4 (severe problem). The questions are grouped in two non-overlapping sets: the RPQ-3 includes early, objective, physical symptoms, and the RPQ-13 group includes later, more cognitive and behavioral symptoms. The RPQ-3 encompasses headache, dizziness, and nausea/vomiting. The RPQ-13 includes questions evaluating noise sensitivity, sleep disturbance, fatigue, irritability, depressed mood, forgetfulness, poor concentration, longer thinking time, blurred vision, light sensitivity, double vision, and restlessness. The RPQ-3 ranges from 0 - 12 (best to worst) and RPQ-13 ranges from 0 - 52 (best to worst). RPQ Total is the theoretical max/min RPQ score with a combined possible score ranging from 0-64 (best to worst). The outcome measures are
