Can DID symptoms go dormant and return later?

What are we calling dormant?

Someone can go years without obvious switching. Then a loss, an accident, a family milestone, or a period of heavy stress brings old patterns back into view. Did the disorder return? Was it there all along?¹²

People use “dormant” for several different experiences. One person may stop noticing obvious switches while still losing pieces of conversations or hearing internal voices. Another may have identity states sharing enough current information that changes leave few visible traces. Sometimes symptoms really are less intense for a while. Clinical literature doesn't give dormancy one fixed meaning, so much of the discussion begins with people's accounts of what those quieter years felt like.¹²

I started with a paper that addresses the question directly: Richard Kluft's 1991 Clinical Presentations of Multiple Personality Disorder. “Multiple personality disorder” was the name used at the time. Kluft was describing the condition now called DID.¹

Kluft's long quiet stretches

Kluft's paper arranges presentations he had encountered in practice and in the earlier literature, asking why the most recognisable version of the disorder appeared so rarely.¹

One of his cases gets very close to the question on this page. Kluft described an accomplished health professional whose dissociation had been overt in adolescence but was not overt from ages 16 to 29 or from 29 to 59.¹ Her diagnosis emerged unexpectedly near the planned end of therapy.

We don't know what those quieter decades felt like to her. Symptoms may have continued outside her awareness or changed enough to escape notice. One case also cannot tell us how often this happens.¹

Six years earlier, Kluft had written a longer chapter about the natural history of the disorder. His observations included 210 people he had interviewed himself, along with patients who declined treatment and returned anywhere from several months to more than a decade later.³

While this paper has a lot of weight to it, there are some shortcomings worth mentioning. The case-finding work was not formally published, participants were not assessed on one schedule, and there was no comparison group. The cases show that Kluft saw this pattern more than once, but they don't tell us how common it was.³

The language in these papers also belongs to its time. Kluft used labels such as “latent MPD” for infrequent stress-related appearances, “posttraumatic MPD” when a later event made a previously covert condition visible, and “epochal” or “sequential MPD” when one state remained dominant while others became inactive.¹ Keep in mind these are historical descriptions that don't map onto DSM or ICD subtypes.

Kluft also described people whose identity states shared current information, pursued common goals, or concealed changes well enough to pass as one for long periods. From the outside, the disorder could look absent even while dissociative activity continued.¹

This is the problem with using one word for all of it. “Dormant” may describe fewer symptoms, less awareness of them, better internal cooperation, or one state staying in control for a long time. In an old clinical record, they may all look like a quiet period.¹

Stress can make symptoms visible again

Kluft saw later trauma and stress make identity changes more obvious, especially when the new situation resembled an earlier danger or loss.¹ Sometimes it lasted briefly. In other cases, the person did not return to the earlier, quieter arrangement.

A recent paper gives us one messy example. After the 2023 earthquakes in Türkiye, clinicians identified 16 clients with DID and reported increased identity-state activity after the disaster, with newly apparent states in several cases.⁴

The team began its work after the earthquake, used no structured diagnostic interview, and lost 11 clients before they completed therapy. The abstract, table, and main text also disagree on how many people changed. I would treat it as an account of what this team saw after a disaster, rather than an estimate of how often stress brings symptoms back.⁴

What WHO says now

WHO's current clinical guidance describes DID as having a “recurrent and fluctuating clinical course.”² Symptoms may remit spontaneously with age and return during periods of increased stress. Older adults may show up with what looks like late-life paranoia, cognitive impairment, or unusual mood, psychotic, or obsessive-compulsive symptoms.²

That still leaves the obvious questions unanswered. How often do symptoms return? How long do the quieter periods last? Who is most likely to go through them? WHO does not give us those answers.²

Coons and Bowman studied a different kind of return: recurrence after treatment. They began with 25 people diagnosed with DID, and 12 provided information ten years later. Six had achieved what the authors called full integration. Two of those six later dissociated into identity states again.⁵

Two recurrences in a follow-up of 12 people leave us with a very small base for calculating the odds. The study also concerns recurrence after treatment, which is different from symptoms becoming quiet on their own.⁵

The study I wanted for this page does not seem to exist: a large group followed from active symptoms, through years of spontaneous remission, and into recurrence.¹²⁵

So, can symptoms go quiet and return? Kluft's cases and WHO guidance both say yes. How often, and why for one particular person, remains harder to answer.¹²

A quiet stretch may mean symptoms eased, changed form, or became harder to notice. If unusual experiences return after years of stability, bring them to a clinician for a new assessment. Neurological conditions, medication or substance effects, sleep problems, and other psychiatric conditions can also affect memory, identity, or perception.⁶
