the proposed breakdown of sensory gating as a factor in Misophonia failed to be supported

In a 2026 study Du et al, proposed that Misophonia may be explained as a breakdown in early sensory gating processes, indicating it as an issue of effective filtering of redundant or irrelevant information before reaching conscious awareness. To test this proposed role of impaired preattentive sensory gating in misophonia, they examined relationships between P50 suppression, resting-state beta and gamma power, and MisoQuest and SGI-B scores. They found self-reported misophonia severity tracked self-reported gating difficulty, but P50 suppression was unrelated to either, and resting beta and gamma power showed at best weak relationships with symptoms. From this they concluded misophonia may not arise from deficits in early, automatic sensory filtering and likely emerges from alterations in higher-order processing networks (Du et al., 2026)
