When people think about autism, they often focus on communication differences, sensory issues, or rigid routines. What tends to get less attention is the importance of transition periods.
A transition period is the space between one state and another. Sometimes that change is small, such as leaving the house, getting ready for school, starting an appointment, or moving from one task to the next. Sometimes it’s far bigger, such as changing school, losing a job, moving house, going through a breakup, or adjusting to a major shift in family life.
For many autistic people, the event itself is only part of the picture. The transition into it, and out of it, can be just as significant, sometimes more so.
Why transition periods are often misunderstood
One difficulty is that transition periods aren’t always obvious, even to autistic people themselves.
A person may know that something feels off, that they’re more irritable than usual, more tired, more avoidant, or less able to cope, but may not immediately recognise that the real issue is change itself. It can look like low mood, anxiety, reluctance, bad behaviour, or simply “not coping well”, when in reality the person is still trying to move from one mental and practical state into another.
That matters because people often judge distress by looking only at the task in front of them. If the task doesn’t look especially demanding, they assume the reaction is excessive. In many cases, they’re looking at the wrong thing.
It isn’t always the event that causes the strain
A child may appear to struggle with school, when the real difficulty lies in the shift from home into school. An autistic adult may dread an appointment, not because of the appointment itself, but because of the preparation, the uncertainty, the travel, the social adjustment, and the recovery afterwards.
This is one reason some autistic people prefer face-to-face appointments over video calls, even though remote appointments are often presented as the easier option. An in-person appointment usually comes with a built-in period of transition. There’s time to get ready, travel, arrive, settle, and gradually move into the interaction. A video call can remove all of that. One moment the person is at home in their own environment, the next they’re expected to be switched on and socially available straight away.
That kind of abrupt shift can feel far more uncomfortable than people realise.
Small transitions can build up quickly
Transition periods don’t need to involve dramatic life events to have an effect. Everyday changes can create a steady accumulation of strain.
Examples include:
- waking up and getting started
- leaving the house
- arriving somewhere unfamiliar
- moving between lessons, activities, or tasks
- switching from solitude to social interaction
- returning home and trying to settle again afterwards
These things may seem minor to other people, but repeated friction across the day can be exhausting. A child or adult might manage each separate demand in theory, but still end the day drained, irritable, or shut down because the repeated transitions have taken more out of them than anyone around them has recognised.
Why parents and professionals can miss it
Transition difficulties don’t always look dramatic. Sometimes they do, particularly in children, where they may show up as meltdowns, refusal, anger, or visible distress. But just as often they’re quieter.
A child may become more rigid, more tired, less communicative, or more easily upset. An adult may withdraw, cancel plans, procrastinate, or seem unable to get moving. These responses are often misunderstood because people look for a single obvious cause and can’t find one.
In reality, the person may be carrying the effect of multiple small changes, or may still be adjusting to a larger one that others assume should be “over by now”.
This matters well beyond autism. Many public systems are built as if people can move cleanly and quickly from one state to another, with very little thought given to the process in between. The same blind spot turns up in education, transport, health services, and public administration. It’s part of the reason broader systems often fail people with additional needs in the first place, something touched on in both The Case for Nationalising Britain’s School Transport and Reasonable Case Management System. In both contexts, the core problem is similar. Systems are usually designed around process efficiency, not around the lived reality of how people actually move through change.
Larger routine changes can have a prolonged effect
The same principle applies to much bigger transitions, and this is where the impact can become more serious and longer lasting.
A breakup, for example, isn’t only emotionally painful. For an autistic person, it can also represent the collapse of an established structure. The relationship may have shaped daily routines, future expectations, communication patterns, emotional regulation, and a sense of stability. When that disappears, the problem isn’t simply grief or disappointment. It’s the loss of a whole familiar pattern of life.
The same can happen with bereavement, divorce in the family, moving house, changing schools, leaving education, starting work, losing work, or entering a new stage of adulthood. Even positive changes can be deeply unsettling if they require a person to leave behind what is known and adapt to something unfamiliar.
This is an important point for parents. It’s easy to assume that once the practical change has happened, the child or young person will begin to settle. Sometimes they do. Sometimes they don’t, at least not quickly. The formal event may be over, but the transition period is still ongoing.
Why the effects can last longer than expected
Autistic people are often expected to recover from change according to somebody else’s timetable.
A child starts a new term, so people assume the difficult bit has passed. An adult moves house, so others expect them to be settled once the boxes are unpacked. A relationship ends, and after a few weeks there’s an assumption that life should have adjusted around the loss.
That isn’t always how it works.
When routines, attachments, and familiar structures have been disrupted, the adjustment period can last much longer than outside observers expect. The person may still be trying to orient themselves within a new version of daily life. That can affect energy, mood, concentration, social tolerance, and general functioning for quite some time.
This doesn’t necessarily mean something has gone badly wrong. It may simply mean the transition is still taking place.
A brief personal note
This is something I only came to understand properly relatively recently, and I’m 27.
I’d long known that certain changes hit me harder than they seemed to hit other people. I knew I preferred some forms of structure and found some forms of abrupt change more uncomfortable than I could easily explain. What I hadn’t fully appreciated was how much of that sat in the transition itself.
Once you notice it, a lot of past experiences start to make more sense.
What can help
The first step is simply to take transition periods seriously.
That means recognising that the problem may not lie in the event itself, but in the lead-up, the shift, the loss of the previous routine, or the aftermath. Once that’s understood, support can become far more sensible.
Helpful approaches can include:
- giving clear notice of changes where possible
- avoiding abrupt or unnecessary disruption
- allowing extra time before and after demanding events
- keeping some routines stable during larger life changes
- recognising that recovery time is often part of coping
- asking whether the difficulty lies in the task itself, or in the transition around it
For parents, this often means looking beyond the surface behaviour. A child who seems unreasonable, defiant, or over-sensitive may actually be struggling with a change that hasn’t been properly acknowledged. For autistic adults, it can mean realising that difficulty with transitions isn’t a personal failing, but a genuine part of how change is processed.
Final thought
Transition periods are often treated as background detail. In autism, they can be central.
That applies to small everyday changes, such as leaving the house or moving between tasks. It also applies to major shifts, such as changing schools, moving home, bereavement, or the breakdown of a relationship.
Sometimes the hardest part isn’t the thing people can see. It’s the process of leaving one state of life behind and trying to find your footing in the next.
