The subtypes of visual hypersensitivity are transdiagnostic across neurodivergence, neurology and mental health

Area of Science:

• Neuroscience
• Psychology
• Ophthalmology

Background:

• Neurodivergent individuals often experience heightened sensitivity to visual stimuli, impacting daily life.
• The transdiagnostic nature and underlying mechanisms of visual hypersensitivity remain unclear across various conditions.

Purpose of the Study:

• To investigate the transdiagnostic patterns of four visual hypersensitivity subtypes across diverse neurodivergent, mental health, and neurological conditions.
• To determine if visual hypersensitivity represents a shared vulnerability across these conditions.

Main Methods:

• Surveyed 2582 participants across 11 conditions (Autism, ADHD, Dyslexia, Dyspraxia, Fibromyalgia, Migraine, PPPD, synaesthesia, Distress, Eating Pathology, Fear).
• Assessed self-reported sensitivity to four visual subtypes: Brightness, Pattern, Strobing, and Intense Visual Environments.
• Utilized regression analyses to control for comorbidities and identify unique predictors.

Main Results:

• All four visual hypersensitivity subtypes were reported across all 11 conditions.
• Sensitivity to Intense Visual Environments was particularly prominent in Autism, ADHD, Dyslexia, and Dyspraxia, forming a shared pattern.
• Autism, Fibromyalgia, Migraine, and PPPD were the strongest unique predictors of visual hypersensitivity.

Conclusions:

• Visual hypersensitivity is a transdiagnostic phenomenon with shared underlying vulnerabilities in perceptual systems.
• Distinct patterns of visual hypersensitivity subtypes transcend traditional diagnostic boundaries, suggesting common etiological factors.
• Findings imply a unified approach to understanding and managing visual sensitivities across diverse clinical populations.
