Overview
Differences in how sensory information is received, interpreted, and responded to, which may result in over-sensitivity, under-sensitivity, or sensory-seeking behaviours that affect daily functioning.

- Distress or discomfort in busy or stimulating environments
Impact on functioning
- Difficulty tolerating classroom environments due to noise or sensory stimulation
- Avoidance of certain activities such as group work, physical education, or messy play
- Emotional distress or behavioural escalation in overstimulating settings
- Challenges participating in daily routines or school activities
