Summary

This study aims to investigate the feasibility of the use of repetitive transcranial magnetic stimulation (rTMS) for symptoms associated with Visual Snow syndrome (VS).

Detailed description

The study will gather information about the treatment of up to 10 people with VS using rTMS. Treated participants will undergo 10 sessions of rTMS administered 5 times a week over 2 weeks. All visits will take place in the University of Colorado School of Medicine NeuroMag/Transcranial Magnetic Stimulation laboratory on University of Colorado Anschutz Medical Campus. The specific aims for this feasibility study include: 1. Determine whether any participant experiences untoward effects of rTMS in the setting of visual snow syndrome and determine the potential drop-out rate of larger study. 2. Determine the performance of a novel scale (Colorado Visual Snow Scale) and two three psychophysical visual processing tasks 1. Determine the standard deviation and test-retest reliability for the novel scale and two visual processing tasks 2. Determine whether the visual processing tasks perform similar to performance found by the developer 3. Describe changes in outcome measures between pre- and post-treatment with rTMS
