Autistic meltdowns and shutdowns in adults: what helps and what to avoid

This guide is for autistic adults and for the family, partners and friends around them. A meltdown is an intense response to being overwhelmed that shows on the outside. A shutdown comes from the same overwhelm and is held on the inside. Neither is chosen. It covers triggers and early signs, what helps and what makes things worse, recovery, and writing a plan together.

Meltdown and shutdown

What a meltdown and a shutdown are, side by side

The National Autistic Society describes a meltdown as an intense response to an overwhelming situation, when somebody becomes completely overwhelmed and temporarily loses control of their behaviour. A shutdown starts from the same overwhelm and goes the other way, into silence and stillness.

Meltdown

The overwhelm shows on the outside

Shouting, crying, kicking out, or hurting themselves

Shutdown

The overwhelm is held on the inside

Silence, stillness, withdrawing, not able to answer

  1. Before

    Early signs

    Meltdown

    What you may see

    Signs of distress building. The National Autistic Society calls this the rumble stage: pacing, asking the same question again and again, rocking, or going very still.

    What helps

    Lower the demands and the noise now. This is the point where a meltdown can sometimes be avoided.

    Shutdown

    What you may see

    A similar build-up that can be harder to see from outside. Answers may get shorter, stimming may increase, and small decisions can become difficult.

    What helps

    Take questions and choices away, offer a quiet room, and do not read the short answers as rudeness.

  2. During

    At the peak

    Meltdown

    What you may see

    An intense response to being completely overwhelmed, with a temporary loss of control. It can be verbal or physical, and it is not chosen.

    What helps

    Keep everyone safe, say very little, turn down light and sound, and give space. One calm person stays nearby.

    Shutdown

    What you may see

    The person may stop speaking, seem zoned out or unresponsive, go to bed or a dark room, or be unable to move on to anything.

    What helps

    One short sentence about what happens next, then quiet. Stay within reach if they want you there, and leave them alone if they do not.

  3. After

    Recovery

    Meltdown

    What you may see

    Tiredness, often a great deal of it. The National Autistic Society notes that it can take a while to recover from that much sensory or information overload.

    What helps

    Rest, food and drink, and familiar things. Talk about what happened later, and only if the person wants to.

    Shutdown

    What you may see

    Energy and speech may come back slowly. A sudden loss of energy is part of a shutdown, so the tiredness does not lift at once.

    What helps

    Keep the rest of the day light. Writing or texting may be easier than talking for a while.

What the two have in common

  • Neither one is done on purpose, and the person cannot simply stop it.
  • A meltdown is not a tantrum. It is not aimed at getting something.
  • A shutdown is not ignoring you, sulking or refusing.
  • Some people have meltdowns, some have shutdowns, and some have both at different times.
What any one person looks like before, during and after is their own. This is a general picture drawn from the National Autistic Society, Autistica and NHS guidance, and the person themselves is the best guide to theirs.

Leicestershire Partnership NHS Trust explains the difference through the body's fight, flight or freeze response. A meltdown is the fight response. It can be verbal, such as shouting, growling or crying, or physical, such as kicking or flapping, or both. A shutdown is the freeze response: the person may become unresponsive, find speaking hard or impossible, and want to hide somewhere dark and quiet. Autistica adds that a meltdown can include self-injury.

Why a meltdown is not a tantrumSection titled Why%20a%20meltdown%20is%20not%20a%20tantrum

The National Autistic Society is clear that a meltdown is not a temper tantrum and not bad or naughty behaviour. A tantrum has a purpose, such as getting something or avoiding something, and it tends to ease when that purpose is met. A meltdown has none. The Leicestershire trust describes it as a loss of control that is not aimed at getting support, which is why rewards, warnings and reasoning do not end one. NHS Scotland's guidance goes further and says neither meltdowns nor shutdowns should be viewed as challenging behaviour.

Why a shutdown is not ignoring youSection titled Why%20a%20shutdown%20is%20not%20ignoring%20you

During a shutdown the person may hear everything you say and still be unable to answer, move or make a choice. The silence says nothing about how they feel about you. Asking again, louder, adds to the overload that caused it.

Autism is not a mental illness and it is not a learning disability, although some autistic people also have one or the other. Autism in adults is the starting point for the rest of this part of the site, and disability care at home covers support more widely.

What builds up to one

Common triggers, and the early signs to look for

Autistica notes that triggers differ from person to person and can build up over time. These are the triggers the National Autistic Society and NHS guidance name.

Sensory overload

A loud room, bright lights, a strong smell or uncomfortable clothes. Being more or less sensitive than other people to these is part of autism for many people, and too much at once can tip into overload.

Noise, light, smell, touch

Change and uncertainty

A cancelled appointment, a different person at the door, a journey by another route. The National Autistic Society suggests explaining a change clearly and saying which parts of the day are staying the same.

Plans that move

Too many demands

A run of questions, decisions and requests, or the pressure to meet what employers, family or friends expect. The National Autistic Society names that pressure as a cause of autistic fatigue, and more frequent meltdowns as one of its signs.

Questions, choices, pressure

Tiredness, hunger and pain

Being tired, hungry, thirsty or in pain lowers how much a person can take. If meltdowns suddenly become more frequent, ask the GP to check for pain or illness, which NICE asks professionals to look for.

Needs not met

Social exhaustion and masking

Social situations, misunderstandings and hiding autistic traits all use energy. Somebody who seemed fine at a family lunch may reach their limit an hour after getting home.

After a long day with people

Not being understood

Struggling to say what is wrong, or being misunderstood, is frustrating and frightening. The National Autistic Society lists communication difficulties among the main triggers.

Communication

The early signs are specific to each person. The National Autistic Society calls this the rumble stage and lists pacing, asking the same question for reassurance, rocking, and becoming very still. The Leicestershire trust adds that a person may lose the ability to mask. At this stage, taking away the trigger, offering a quiet room or something calming, and staying calm yourself can sometimes stop a meltdown from happening. Sensory needs at home covers changes to the house that cut down overload before it builds.

During one

What helps during a meltdown or a shutdown

The aim during a meltdown or shutdown is not to end it quickly. It is to keep everyone safe and take away as much of the overload as you can, so the person can recover. What follows is general advice from Autistica and the National Autistic Society. Where the person has a plan of their own, follow that first.

  1. 1

    Make the space safe

    First
    Move anything that could hurt the person or anyone else, and give them room. If other people are around, ask them to leave or to stop watching.
  2. 2

    One calm person stays

    Not a crowd
    Autistica advises that one person takes the lead, because several people talking or helping at once adds to the overload. Stay to one side and at the person's level rather than standing over them.
  3. 3

    Turn the input down

    Light, sound, people
    Turn off the television or music, dim bright lights, and close the door on a noisy room. If the person uses ear defenders, headphones or a weighted blanket, put them within reach.
  4. 4

    Say very little

    Short and slow
    If you need to speak, use a few plain words in a slow, low voice. Ask once, calmly, whether they are all right, and allow much longer than usual for an answer.
  5. 5

    Give it time

    At their pace
    The National Autistic Society says it can take a while to recover from sensory or information overload. Stay nearby, calm and quiet, and let the person decide when it is over.
  6. 6

    Offer comfort only in the way they have asked for

    Their choice
    Some people want someone close during a meltdown, and others cannot bear to be touched. Follow what the person told you when they were calm. If you do not know, ask in as few words as possible and accept no as the answer.

A shutdown needs less of all of this. One short sentence about what happens next, such as "I will be in the kitchen, text me if you want anything", then quiet. Stay within reach if the person wants you there, and leave them alone if they do not. If anyone is hurt or at risk, the last section of this page says who to ring.

What to avoid

What makes it worse, and what to do instead

Much of what makes a meltdown or shutdown worse comes from trying to help in the usual way: asking what is wrong, giving a hug, or explaining why it will be all right. For a person who is already overloaded, each of these is more to take in.

Touching without asking

Why it makes things worse
Touch is sensory input. For somebody already overloaded it can be too much, and being held can feel like being trapped.
What to do instead
Keep your hands to yourself unless the person has said, when calm, that touch helps them. Offer, and do not assume.

Asking questions

Why it makes things worse
Each question has to be processed and answered, which the person cannot manage at that moment.
What to do instead
Make one short statement, such as "I am here and I will wait", and then stay quiet.

Holding the person down

Why it makes things worse
Restraint can frighten and injure people, and it adds force to an overload that is already too much.
What to do instead
Make the space safe instead. Autistica advises against restraint unless it is needed to prevent violence or injury.

Telling off or talking about consequences

Why it makes things worse
The person is not choosing this. Autistica notes that talking about consequences increases anxiety.
What to do instead
Stay neutral. Leave any conversation about what happened until the person is rested, and only if they want it.

An audience

Why it makes things worse
Being watched adds pressure, and more people means more to process.
What to do instead
Ask others to leave the room or look away. The National Autistic Society suggests asking people not to stare.

Matching their distress

Why it makes things worse
A raised voice and quick movements add to the noise and the sense of alarm.
What to do instead
Keep your voice low and your movements slow. Autistica advises staying calm and not mirroring the person's emotional state.

Drawn from the guidance on meltdowns from Autistica and the National Autistic Society. The person's own plan comes first where there is one.

Restraint is a legal question as well as a practical one. Section 6 of the Mental Capacity Act 2005 says that restraining an adult who lacks capacity is only protected where the person doing it reasonably believes it is necessary to prevent harm to them, and where it is in proportion to how likely and how serious that harm is. An autistic adult who has capacity makes their own decisions, including about being touched. Mental capacity and how it is assessed explains what capacity means.

Where an autistic person also has a learning disability and hurts themselves or other people, families are sometimes offered a positive behaviour support plan, which challenging behaviour and positive behaviour support explains. That page is written for families of adults with a learning disability, and a meltdown on its own is not challenging behaviour.

Afterwards

Recovery takes time, and the talking can wait

When a meltdown or shutdown ends, the person is often exhausted. It is natural to want to talk it through straight away. Let that conversation wait until the person is rested.

Where you can helpRest and low demandsA sign to look further
  1. Straight after

    Quiet and rest

    Somewhere calm, a drink, something to eat, and no demands. Let the person go to bed or be alone if that is what they want.

  2. Later that day

    Keep the rest of the day light

    Move what can be moved and say so plainly. A visit or a trip that was planned may now be too much, and that is fine.

  3. The next day or two

    Expect the tiredness to carry on

    Energy can take a while to come back, especially after a shutdown. Keep routines familiar and demands low.

  4. Once rested

    Talk about it only if the person wants to

    Some people like to go over what happened and what might help next time, and others would rather not. Writing or texting can be easier than a conversation.

  5. Over weeks

    Notice if they are coming more often

    NHS Scotland's guidance says persistent meltdowns or shutdowns can lead to autistic burnout: long-term exhaustion, losing skills the person had, and less tolerance of noise and light. Autistic burnout explains what helps.

Nobody needs to be blamed for a meltdown, including the person who had it. If the person wants to, they can add what they learned to their own plan.

Planning ahead

A plan the person writes and agrees, and when to get more help

The best time to decide what helps during a meltdown or shutdown is when nobody is having one. The Leicestershire trust advises talking about preferred responses in calm moments, so that there is a plan that fits the person. The plan belongs to the person, in their words, and they decide who reads it.

When I am overwhelmed: my plan

Written with the person, in their words, when they are calm. Agreed by them, and kept where the people who need it can read it.

Signs I am getting overwhelmed
I start asking what time it is over and over. I stop answering in full sentences.
What helps me early on
Turn the television off. Let me go to my room without asking why.
During a meltdown or shutdown, please
Say one thing, then stop talking. Dim the lights. Stay in the hall where I can see you.
Please do not
Touch me, ask me questions, or bring anyone else into the room.
Afterwards I need
A cold drink, my weighted blanket, and no talking about it until tomorrow.
Who to call if anyone is at risk
My sister first. If someone is hurt, 999. For urgent mental health help, NHS 111.
Agreed by me, and looked at again when things changeCopies: my sister, my support worker, my GP
NICE guidance on autism in adults asks professionals to consider a written crisis plan where it is needed, covering likely triggers, how the person reacts and what families should do. A short plan like this one, written with the person, is the everyday version of the same idea.

Keep it to one page so that it gets read, and give a copy to the people who need it. An autistic adult who has capacity decides who sees their information, so ask before you share it. Look at it again when something changes, such as a move, a new job or a new person helping at home. Autism support at home covers the rest of setting up support, including communication and routine.

Support from somebody outside the familySection titled Support%20from%20somebody%20outside%20the%20family

Some autistic adults want support at home from somebody who is not a relative, such as a calm person who knows the plan. Predictability and the same face matter a great deal to many autistic adults. On PrimeCarers the person, or the family where the person wants them involved, chooses the carer, meets them first, and agrees the hours, the routine and how contact works directly with them, and they can keep the same person for as long as it suits both of them. You can search for carers near you and compare their rates. Carers on PrimeCarers charge £18 to £25 an hour with our fee included, against £28 to £35 an hour at an agency.

PrimeCarers is an introductory service, not an agency or a care provider. Before a carer appears in a search we check their identity and right to work, confirm an enhanced DBS check (or PVG in Scotland, Access NI in Northern Ireland) issued within the last 18 months, and interview them online. Separately, carers are insured while they work. There is no way to search for carers by autism experience, and we do not check qualifications, training or references, so what a carer says about their experience is their own account on their profile, to ask about when you meet. Questions to ask at interview helps with that conversation.

Questions

Questions people ask about meltdowns and shutdowns

Both are responses to being overwhelmed. In a meltdown the distress shows on the outside, as shouting, crying, kicking out or sometimes self-injury, with a temporary loss of control. In a shutdown it is held on the inside: the person may go quiet, stop speaking, seem zoned out and withdraw somewhere dark and quiet. NHS guidance compares a meltdown to the fight response and a shutdown to the freeze response. Some people have both at different times.

No. The National Autistic Society says a meltdown is not a temper tantrum and is not bad or naughty behaviour. A tantrum has a purpose and tends to stop when it is met. A meltdown is a loss of control from being overwhelmed, and rewards, warnings or reasoning will not end it.

It varies from person to person and from one time to the next, and there is no set length. The National Autistic Society notes that recovering from sensory or information overload can take a while, so plan for the rest of the day to be quiet rather than expecting things to go back to normal once the peak has passed.

Only if they have told you, when calm, that it helps. Touch is sensory input, and for some autistic people it adds to the overload. Keep your hands to yourself, stay nearby, say very little, and turn down light and sound. Autistica advises against restraint unless it is needed to prevent violence or injury. The person's own plan is the best guide.

Adults have them too, and the guidance from the National Autistic Society, Autistica and NHS trusts covers adults as well as children. An adult may have learned to mask in public and then reach their limit later, at home.

Make the space as safe as you can and ask others to move away. If someone is seriously hurt or in danger, ring 999. For urgent help with mental health, use NHS 111 online or ring 111 and choose the mental health option. Afterwards, talk to the GP about a written plan.

A carer or support worker cannot prevent every meltdown, but one who knows the person and their plan can help cut down what sets them off and respond calmly. On PrimeCarers the person chooses and meets the carer first, and can keep the same person. There is no way to search for carers by autism experience, and we do not check training or qualifications, so ask about their experience when you meet.
