Transcranial Photobiomodulation in Anxiety Disorders
Sponsor: University of Texas at Austin
Summary
The investigators have previously shown that safe, non-invasive methods of brain stimulation such as the administration of transcranial infrared light can result in improvements to cognition and emotion. The investigators hypothesize that transcranial photobiomodulation (tPBM) can be used in conjunction with attention bias assessment and modification to reduce anxiety symptoms in individuals with sub-clinical anxiety.

Attention bias assessment and modification
Attention bias assessment and modification involve two versions of the dot-probe task. These tasks are based on the premise that repeated attention shifts can retrain attentional biases, with the expectation that reducing attentional bias toward threats will alleviate sub-clinical anxiety symptoms.
Transcranial photobiomodulation
Participants will receive near-infrared light at 1064 nanometers to the right side of the forehead for 8 minutes. The investigators have introduced this form of transcranial photobiomodulation (tPBM) as a means of human cognitive enhancement, and as an adjunct for attention bias modification for the reduction of symptoms of depression. In the present study, the investigators wish to extend these findings to the use of attention bias modification for the reduction of sub-clinical anxiety.
