What Are We Actually Treating When We Treat RSD?

And what gets lost when a label replaces the harder work of knowing yourself.

In this piece:

• Why RSD and DESR are not the same thing, and why the conflation is clinically costly

• What the neurobiology of ADHD actually tells us about emotional dysregulation

• Why locating relational pain in biology forecloses the work that could genuinely change it

• What depth psychology offers that a checklist cannot

• Why every person who presents with rejection sensitivity has a backstory, and why that backstory is the treatment

A Label in Search of a Diagnosis

Rejection Sensitive Dysphoria (RSD) has become one of the most frequently used terms in contemporary mental health discourse. It appears in TikTok threads, ADHD support groups, therapy waiting room conversations, and increasingly in clinical notes. People find in it a language for something real and painful, the experience of emotional responses to perceived rejection that feel disproportionate, overwhelming, and impossible to manage.

That experience deserves to be taken seriously. However, what deserves scrutiny is the explanation being offered for it.

RSD is not a diagnosis. It does not appear in the DSM-5 or the ICD-11. It was coined in the 1990s by a psychiatrist observing patterns in his ADHD caseload, gained informal recognition within online neurodiversity communities, and has since been adopted so widely that many people arrive in clinical settings holding it as established fact. The first formal case series examining it was published only in 2024. The research, such as it is, cannot agree on a consistent definition.

This matters not because the suffering it points to is unreal. It matters because the explanation shapes the treatment. And when the explanation is wrong, the treatment misses.

The Difference Between DESR and RSD

Russell Barkley has spent decades arguing, with considerable research support, that emotional dysregulation is a core and largely overlooked feature of ADHD. His term, Deficient Emotional Self-Regulation (DESR), describes a constitutional difficulty with inhibiting inappropriate emotional responses, self-soothing under intensity, refocusing attention away from emotionally provocative events, and substituting healthier responses in the service of longer-term wellbeing. This is a defensible phenomena, grounded in rigorous research. A meta-analysis of 77 studies across more than 32,000 participants supports his position. Barkley is explicit that medication is the primary intervention for this layer, and he is sceptical that psychotherapy can meaningfully alter the underlying neural substrate.

There is however a departure, where RSD is not DESR and the two cannot be collapsed into a single concept. RSD describes something phenomenologically adjacent but mechanistically distinct. Where DESR is about the regulatory capacity of the nervous system, RSD makes a specific claim about rejection as the trigger and dysphoria as the response. It implies a particular relational sensitivity, organised around the fear of abandonment and the catastrophic experience of disapproval, that Barkley’s framework does not actually address.

What seems to have happened, both culturally and clinically, is that these two things have been collapsed into one. The constitutional substrate has been used to authorise the relational construct. And the result is that a complex, structurally specific clinical presentation is being treated as though it were a single neurobiological fact.

What Biology Can and Cannot Explain

There is a real and important connection between neurodevelopmental constitution and personality structure. Many theorists, like Kernberg, recognised this. Neurobiology produces emotional experience, and emotional experience is the raw material from which object relations are formed. In other words, our innate, biologically driven temperament dramatically influences how we symbolically represent ourselves and others. This, in turn, impacts how we come to see ourselves, others and how we interact. It is the patterns we learn in our early relationships that then shape our relational blueprint, often playing out in relationships throughout our lifetime.

The ADHD child is often constitutionally intense, impulsive, relatively harder to attune to, and presents a particular challenge to caregivers. Given the strong heritability of neurodivergence, those caregivers are often themselves dysregulated, themselves carrying unprocessed material, themselves harder to reach. The dyads, or parent-child dynamics, that form in this environment can be turbulent. This can result in misattunement, sometimes leaving lasting structural residue. And then trauma may enter, further complicating what is constitutional and what is acquired. Gabor Maté has argued, persuasively, that the boundary between these is less clean than the pure neurodevelopmental model assumes.

The point is not that biology does not matter. The point is that when we explain the entirety of a person's relational pain as neurobiological, we remove the possibility of understanding it. We tell the person that this is simply how their brain is built, that the task is management and accommodation, and that expecting genuine change is asking too much. I worry that this is implicit in RSD. Psychotherapy, through this lens, does not particularly help patients with RSD because the emotions arrive too suddenly and overwhelmingly for any reflective process to intercept them.

That position may be accurate for the constitutional layer. However, I don't think it is accurate for everything that has grown on top of it.

Everyone Is a Lead Character with a Backstory

When someone arrives in the consulting room identifying with RSD, the first clinical question that comes to mind is not whether the label fits. It is what it is covering. What is it trying to crystalise? The suffering is real; however, the pain is unique and individual.

No two people arrive at the same presentation by the same route. For some, what looks like rejection sensitivity is the activation of a paranoid-persecutory dynamic, a rehearsed relational pattern in which ambiguity is automatically filled with the expectation of abandonment or punishment. The reactivity is not to rejection per se. It is to ambiguity. Clear rejection often produces less dysregulation than an unanswered message, because ambiguity is precisely what the defence was built to fill. This is accessible to interpretation in the transference. It is not captured in a single RSD snapshot.

For others, what presents as rejection sensitivity is better understood as a shame-expulsion defence. The exposure of equivalence, of being ordinary, of having contributed to a poor outcome, can be intolerable within a narcissistic structure and is evacuated by relocating deficiency into the other. The intervention required is containment of shame before interpretation, not validation of a constitutional trait that sidesteps the unbearable pain of shame.

For others still, what looks like hypersensitivity to criticism can be disorganisation under positive attention. The person finds it difficult to receive warmth, struggles to metabolise recognition, deflects compliments with such automaticity that they have never examined the rule underneath. This patient is not oversensitive to rejection. They are unfamiliar with being seen. Telling them they have RSD and offering reassurance is contraindicated. It is the intervention they cannot use.

And then there is the presentation where the RSD framing has most partial validity, the person with genuine, established ADHD who carries years of accumulated shame from repeated, public, unintended failures to meet social norms. The executive function substrate is real. The shame is consequent, not constitutional. Even here, the more generative clinical question is what internalised voice is operating, how harsh it is, and how it came to be that way. The RSD framing naturalises the sensitivity and forecloses that conversation.

The Get Out of Jail Free Card

I am also concerned that the RSD label can function, for some people, as a way of avoiding responsibility for their sensitivity. When the difficulty is framed as an immutable neurobiological fact, the pressure to reflect on one’s contribution to a relational rupture is relieved. The aggression that might more honestly be named as such gets inverted. What should be experienced as I am angry and I want to attack arrives instead as you have wounded me and I am the victim. The label legitimises the response. It forecloses the inquiry.

This is not a character flaw in the person who uses it this way. It is a predictable consequence of a framework that locates the difficulty entirely outside the person’s agency. When someone is told, repeatedly, that their responses are neurologically determined and not their fault, they lose access to the part of themselves that could engage differently. The secondary gain is real. The cost is also real.

RSD as Dream

In clinical practice I approach RSD the way I approach dream material. You do not interpret a dream by taking it literally. You treat it as a communication, a surface that is pointing toward something underneath. The dream is not the explanation. It is the beginning of the inquiry.

RSD tells you that something painful is happening in the relational field. It tells you the person has developed a particular sensitivity to the possibility of disapproval or abandonment. It tells you the affect is intense and arrives quickly. These are useful observations.

However, the particular texture of the relational pattern, the developmental wound, the internalised voice, the structure that was built to manage an environment that is no longer present, that is what depth work is for. That is what labels struggle to reach, and what no medication can address.

I trained in Johannesburg South Africa, worked in Dubai, and now practise in the United Kingdom. Across all three contexts the same thing has been true. The people who benefit most from depth work are the ones who arrive willing to be curious about their own interior life rather than certain about their diagnosis. The label can be a starting point. It becomes a problem when it is treated as an endpoint.

The question worth asking is not whether the sensitivity is real. The question is what it is made of, and for whom, and why. That is a question that takes time, and a relationship, and the willingness to sit with not knowing. It is not a question a checklist can answer.
