Official title
Visual Perception in Visual Snow Syndrome
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is to learn more about the brain pathways and activity involved in creating Visual Snow Syndrome (VSS). The main questions it aims to answer are: * Does VSS arise from spontaneous activity in brain pathways? * Where in the brain does the activity contributing to VSS arise? * How does brain activity contribute to VSS? Participants will: 1. Undergo assessments and questionnaires to understand visual and mental symptoms, cognitive, and sensory function. 2. Make visual judgements based on images presented to them both inside and outside a magnetic resonance imaging (MRI) machine. 3. Undergo scanning of their brain while inside of an MRI machine.
