Meltdown An autistic meltdown is a severe, involuntary response to overwhelming situations where a person loses control of their behavior and emotions due to being overstimulated or experiencing sensory overload. It’s different from a tantrum, as it’s not a deliberate attempt to manipulate or get attention. Instead, it’s a visceral reaction to feeling overwhelmed, and the person may struggle to communicate or regulate their emotions.

Monotropism is a theory suggesting that autistic individuals tend to focus their attention and energy on a smaller number of interests or topics, leading to intense focus and potentially missing or overlooking information outside of that focused area. It’s a way of processing information where fewer interests are aroused at any given time, and those interests attract more processing resources, making it harder to shift attention.
