Separation anxiety disorder can be diagnosed in an adult. That has only been true since 2013, and the change matters more than a technical revision usually would.
Before it, the diagnosis lived in the section of the manual reserved for conditions first appearing in infancy, childhood or adolescence. An adult could receive it only if the onset could be traced back before the age of eighteen. [bogels-2013-separation] Anyone whose problem started at thirty had, formally, nothing.
Most adult cases did not start in childhood
The assumption behind the old rule was that adult separation anxiety is childhood separation anxiety that never resolved. When researchers actually checked, that turned out to be the minority case.
A cross-national analysis of community surveys found that 43.1 per cent of all lifetime onsets began in adulthood. [silove-2015-separation] Close to half of everyone who has ever had the disorder developed it as an adult, with no childhood history to trace.

- Onset in adulthood 43%
Proportions of lifetime onsets from the cross-national World Mental Health Surveys analysis cited in this article.
This is the one figure worth carrying out of this article. A condition that was defined as paediatric turns out, on measurement, to begin after eighteen almost half the time. The definition was wrong, not the patients.
What it looks like at forty
The attachment figure changes; the mechanism does not. In adults it is usually a partner, an adult child or an ageing parent rather than a caregiver in the childhood sense.
The distress concentrates around actual or anticipated separation, and the behaviour that follows is the recognisable part:
- Repeated calls or messages during a separation, specifically to confirm the person is unharmed.
- Real difficulty sleeping when they are not in the house.
- Turning down travel, promotions or social occasions that would require a night away.
- Physical symptoms in the hours before a separation, commonly nausea, headaches or stomach pain.
- Intrusive images of a car accident, an illness, a phone call that does not get answered.
Most people describing this know it is disproportionate. Insight does not dissolve it, which is true of anxiety disorders generally and is one reason self-directed effort so often fails.
Why it goes unnamed for years
It gets read as a personality problem rather than a condition, and it gets read that way by everyone involved. The partner experiences it as clinginess or control. The person experiencing it usually agrees, and describes themselves as needy rather than unwell.
Clinicians contribute too. Anyone trained before 2013 learned this as a childhood disorder, and a diagnosis you were taught does not exist in adults is a diagnosis you do not look for. It gets recorded as generalised anxiety, as a relationship difficulty, or as nothing at all.
The cost of the mislabel is that the treatment never gets offered. Relationship counselling addressed at a couple’s communication does not touch a fear that one of them will die on the motorway.
Separation anxiety and anxious attachment are not the same
They overlap enough to be confused and differ enough to matter. Anxious attachment describes a pattern in how somebody relates to closeness across their relationships. Separation anxiety disorder is a diagnosis with thresholds: the distress has to be excessive for the person’s developmental stage, persist for at least six months in adults, and cause real impairment.
Plenty of people with an anxious attachment style never come near those thresholds. The practical dividing line is whether the fear has started making decisions for you, about where you work, whether you travel, how far away you are willing to live.

What treatment involves
Cognitive behavioural therapy is the recommended psychological treatment for anxiety disorders in adults, and it goes after the behaviour rather than the belief. [nice-cg113-separation]
That means the checking calls, not the fear behind them. A course would work towards tolerating a separation without seeking confirmation, then a longer one, letting the anxiety rise and then fall without being cut short by a reassuring text. The reassurance is what keeps the prediction untested, in exactly the way it does in other anxiety presentations.
Medication used for other anxiety disorders is sometimes added, particularly where the anxiety is severe enough that starting the behavioural work is not realistic.
What to say at the appointment
Name it. “I think this might be separation anxiety disorder, and I know that was a childhood diagnosis until recently” is a more useful opening than describing yourself as anxious about your relationship, because it points at a specific set of criteria rather than a general state.
Bring the concrete details: who the person is, what you do during a separation, what you have declined because of it, and how long it has been going on. Six months is the duration threshold in adults, so how long matters as much as how bad.
If you want a rough measure of the general anxiety sitting alongside it, the anxiety screener here is a reasonable thing to complete and take with you. It does not measure separation anxiety specifically, and no screener on this site does.
