Autism implosion,” or a silent meltdown, is an internal, non-verbal reaction to being overwhelmed, where an autistic person withdraws and disconnects rather than engaging in external outbursts. It is a survival mechanism where the brain shuts down due to sensory, emotional, or information overload, making it difficult or impossible to communicate needs. like external meltdowns, implosions are not a choice, they often prevent the individual from receiving help, and can cause internal damage because the intense energy and distress have no outward release, it’s all turned inward and against the individual.
