Definition
Sensory overload is a state in which sensory input exceeds processing capacity, producing distress, cognitive impairment, or shutdown. It is common in autism, ADHD, migraine, and after concussion — and can occur in typical nervous systems under sufficient load.
Why it matters
Naming sensory overload as biology, not weakness, changes both self-relation and environment design.
The Science
Sensory processing differences are documented across many conditions. Environmental modifications reduce distress and improve function.
The NSI Perspective
NSI treats sensory overload as legitimate physiology deserving accommodation.
Clinical Implications
Sensory-friendly environments are legitimate clinical infrastructure.
Practical Application
If bright lights, crowds, and loud noise overwhelm you, you are not being dramatic. That is a nervous system reading its limits.
