Perceptual Uncertainty and Its Monitoring in Visual Snow Syndrome: A Multimodal Framework

Clinical and Translational Neuroscience
Neurobehavioral signatures, such as cortical hyperexcitability, thalamo-cortical dysrhythmia, and pulvinar dysfunction, appear to drive the persistent visual misperceptions in Visual Snow Syndrome (VSS).

Learnings from familial visual snow syndrome: A case series

Headache: The Journal of Head and Face Pain, Volume 66, Issue 6, Page 1419-1424, June 2026.
Abstract Visual snow syndrome is a neurological condition defined by the core symptom of visual snow and various additional visual and nonvisual symptoms. It can be of significant impact for affected individuals and treatment is currently challenging. Following an index patient reporting a clustering of visual snow syndrome in his family, we identified

Visual snow syndrome: a review on diagnosis, pathophysiology, and treatment [PDF]

Current Opinion in Neurology, 2020
Purpose of review Visual snow is considered a disorder of central visual processing resulting in a perturbed perception of constant bilateral whole-visual field flickering or pixelation. When associated with additional visual symptoms, it is referred to as visual snow syndrome. Its pathophysiology remains elusive.

Mindfulness and MBCT-vision (mindfulness-based cognitive therapy modified for visual symptoms) for visual snow syndrome: a therapeutic perspective

Frontiers in Neurology
Visual snow syndrome (VSS) is a neurological disorder characterized by intrusive visual symptoms and associated with dysregulation in brain networks, including the Salience Network, Default Mode Network, and thalamocortical circuits.

Unmasking the noise: aberrant cortical oscillations in visual snow syndrome

The Journal of Headache and Pain
Background Visual snow syndrome (VSS) is characterised by persistent visual static and disabling perceptual disturbances, yet its underlying neural mechanisms remain poorly understood and are frequently confounded by migraine comorbidity.
