I’m Not Ignoring You – My Brain Has Left the Building. The “Freeze” Response and Why We Go Silent, Not Loud.
Question for my Autistic readers: Do you have, or have you ever had, a shutdown? If so, how would you describe them to other people? Also, what would you like people to know about them?
What IS an Autistic shutdown?
Similar to an Autistic meltdown, when an Autistic person has a shutdown, it is an involuntary nervous system response to compounding environmental or internal stressors.
Autistic shutdowns are a state of extreme overwhelm that can make it hard to think, move, or communicate clearly (assuming we normally have easy access to communication). As meltdowns are, shutdowns too are neurological events (like panic attacks or seizures).
Remember, both Autistic shutdowns and Autistic meltdowns are not a choice. They are neurological “overflows,” like a bucket of water that has become too full and spills over, or a brain shorting out from too much input and tripping a breaker.
What does a shutdown look like?
To the outsider looking in, meltdowns are often (but not always) more visible than shutdowns.
Meltdowns tend to be more external and can include screaming, rage, and outbursts.
Shutdowns, on the other hand, tend to be more internal, causing a person to go silent, freeze, or become very still. Because shutdowns tend to be quiet and less ‘disruptive‘, onlookers may not notice them.
When an Autistic person enters a shutdown, we may go completely (or mostly) silent, stare blankly, and not be able to speak (and may struggle to decode and understand spoken words). We may withdraw or become completely (or mostly) still.
When shutdowns happen, we’re pushed into a freeze state (of fight-flight-freeze-fawn).
The meltdowns we spoke about previously tend to show up as a fight-or-flight state.
Fawning is another response to danger (or perceived danger) that some of us develop in response to trauma. More on fawning and Autistic masking in a minute.
What is the difference between a shutdown and someone giving you the silent treatment?
Something else that onlookers may not understand is how an Autistic shutdown differs from being given the silent treatment (because from the outside they can appear similar). However, an Autistic shutdown is a neurological event, while the silent treatment is a social tactic.
A shutdown is something that happens to an Autistic person. It is involuntary and is not something we choose.
A shutdown is an involuntary reflex. Our brain is pulling the emergency brake because it has become too overwhelmed to function.
The silent treatment, by contrast, is about control.
Unlike shutdowns, the silent treatment is a strategy some people choose.
The silent treatment is a deliberate decision to ignore someone, often to punish them or gain power in an argument.
The key difference between the two is about the internal experience.
During a shutdown, we are trapped inside our own heads. We can hear people, and we may desperately want to respond, but our voice simply may not work.
During the silent treatment, the person can speak, but they actively and consciously refuse to. A person using the silent treatment may feel angry, justified, or in control of their choice.
Another key difference between the two shows up in the aftermath.
A shutdown leaves an Autistic person completely drained, exhausted, and often ashamed, because it’s a physical crash we can’t stop. We often may need to go into a recovery period before we can communicate again.
The silent treatment doesn’t cause physical exhaustion. It is a power dynamic that usually shifts the social situation, like waiting for the other person to apologize or give in.
So… since the main difference between the silent treatment and an Autistic shutdown is the internal experience, let’s dive more deeply into what it is actually like for Autistic people when we shut down.
Meltdowns are loud, external, and visible.
Shutdowns are silent, internal, and often invisible. To the outside world, they look like ‘blank stares’ or even passive aggression. But internally, a shutdown is a fight-or-flight response turned inward (a freeze state where the connection between the brain and the body is severed).
In the full piece, I take you inside the shutdown: the physical symptoms, the dissociation, and the terrifying feeling of losing control.
