One of the most obviously recognizable autistic traits are meltdowns. Stimming can often be done in subtle ways, allistic-type social skills can often be learned, but meltdowns are simply beyond control. Unfortunately, they’re frequently misunderstood and mishandled by others who don’t realize what they’re seeing.
As always, we want to emphasize that meltdowns are different for everyone. Some autistic people have regular meltdowns. Some experience them rarely or not at all. And they can be caused by different things and experienced differently by different people.
Meltdowns are caused by an overload in the brain. This can be sensory overload, extreme anxiety, emotional distress, or stress: basically, there is too much or something and the brain can’t cope. Whatever the cause, the brain is in a state where it can no longer handle further input.
Many autistic people, especially adults with a lifetime of experience, are able to recognize when they are getting overloaded and are headed for a meltdown. Some people are able to leave the situation which is causing their overload and give themselves time and space for their brains to “catch up” so they can calm down and avoid the meltdown. Sometimes, however, it’s not possible to leave a situation - and sometimes, it’s not clear to the person what is happening. For example, alexithymia might prevent them from being aware that they are getting overloaded. If the person remains in the overload-inducing situation, a meltdown can occur (The person can also experience a shutdown - we’ll get into this in a minute.). Sometimes the meltdown is also caused by internal reasons (anxiety, emotional distress) which can hardly be avoided.
Once in a meltdown, the person no longer has normal control over themselves. The brain goes into “fight or flight” mode. The brain perceives a threat - the cause of the sensory overload, or stress, or whatever people happen to be nearby when it happens. It can also be a vague sense of danger / pain that’s not directed at anything. Logic and reason go out the window, and the person is gripped by a tremendous sense of panic and danger. For some people, their brain is saying: YOU ARE NOT SAFE. YOU NEED TO GET AWAY. Picture a cornered prey animal preparing to fight for its life. That’s the state the brain is in.
The person will then react to the situation as though they are in extreme danger - even if they are logically aware that they are not. Common reactions include:
Throughout this experience, the person may feel physical pain as well as panic. Common descriptions include having bees in your head, feeling like your skin is trying to crawl off of you, feeling like your chest is trying to implode, or having nerve pain that shoots up and down your body.
In addition to panic, the person is quite likely to feel profound embarrassment and/or shame, especially once the meltdown is over and the person is calming down, and especially if it happened in public. They are often aware that what they are doing is irrational, and they know how awful they look while it’s happening, but they cannot control it in any way.
This is an important thing to note: Meltdowns cannot be controlled or stopped once they begin. They are not related to temper tantrums, which they are commonly mistaken for. A temper tantrum is someone behaving in an extreme way in order to get attention or to manipulate others into giving them what they want. A meltdown is in no way voluntary. It is more like a seizure: a neurological event which cannot be controlled or stopped (though it might be shortened in some situations, and can definitely be made worse).
If a character in your story sees the meltdown happen, there are ways to help, and there are ways to make it worse. If the person knows what is happening and what to do, they can help make the meltdown as short and painless as possible in the following ways:
Naturally, such perfect “meltdown companions” rarely exist in most autistic people’s lives. Your average well-intentioned friend or family member, and certainly your average stranger, are likely to react in the following ways, and with the following results:
The amount of time a meltdown takes to pass depends greatly on the individual and the situation. They can pass in a minute or two, or they can last for upwards of an hour, especially if the person is forced to remain in the situation which triggered it. On average, they tend to end within 15-20 minutes. If left alone under ideal circumstances, they can be shortened dramatically.
When the person feels that the threat has passed and the brain has calmed itself down sufficiently, the meltdown can end. The character can gradually calm down and regain control of themselves. Aside from potentially feeling embarrassed and ashamed, they are also likely to feel exhausted, as meltdowns expend a lot of energy. Some people will even curl up wherever they are (under a table, inside the sofa, wherever) and immediately take a nap. Their cognitive functions (ability to think clearly) might take some time to go back to normal.
That’s all for meltdown. A masterpost about shutdowns will follow shortly, as well as some posts describing the mods’ personal experience with both type of reactions so you can have a concrete example. Happy writing! (Here we are, giving you more options to make your characters suffer. Do you really need that.)
