1026 Impact Of Blue Light Therapy On Cortical Structure, Sleep, And Anxiety Symptoms Following Mild Traumatic Brain Injury

Abstract

Cortical abnormalities following a mild traumatic brain injury (mTBI) are often associated with abnormal sleep and increased anxiety. Both fatigue and altered mood may be improved through daily morning exposure to blue wavelength light therapy (BLT). The pres- ent study focused on identifying the effect of BLT compared to the placebo amber-light therapy (ALT) on cortical volume (CV), anxiety, and sleep-onset latency (SOL) following a recent mTBI, as well as the correlations between changes in these measures.
