Autistic Meltdowns, Shutdowns & Sensory Overload


A meltdown is not a choice or a behaviour to punish.


Meltdowns and shutdowns can happen when sensory, emotional, cognitive or environmental demands exceed a person's available capacity.


Explore clear visual resources about autistic meltdowns, shutdowns and sensory overload, including early signs, nervous-system responses, recovery, co-regulation and supportive approaches.
