When the Presentation Doesn't Fit the Formulation: Neurodiversity in Residential Care

Children in care are significantly more likely to have ADHD, autism, and other neurodevelopmental conditions than the general population. Estimates vary by study and methodology, but the pattern is consistent: ADHD affects somewhere between ten and twenty-five percent of looked-after children compared to three to five percent of the general population; autistic spectrum conditions are similarly overrepresented. The reasons are multiple and overlapping — genetic factors, prenatal exposure to alcohol and other substances, the neurological effects of early adversity on a developing brain. But there is a further and less comfortable possibility: that neurodevelopmental conditions are going unrecognised in care-experienced children because the dominant explanatory framework is trauma. When everything can be attributed to adverse childhood experience, the child whose difficulties have a neurodevelopmental basis may spend years being supported in ways that are thoughtful, committed, and not quite right. The care plan reads as a trauma narrative. It is also, or in addition, a neurodevelopmental one. Nobody has asked the question.

The overlap between presentations associated with developmental trauma and those associated with ADHD and autism is substantial, and distinguishing between them in a young person who has experienced both is genuinely difficult. Emotional dysregulation, difficulty with executive function, impulsivity, hypersensitivity to social cues, problems navigating the implicit expectations of group environments — all of these can reflect trauma history, neurodevelopmental difference, or most commonly an interaction between the two. A residential team working from a trauma-informed model may be providing excellent care and still be missing something significant. The young person who cannot sustain attention during a keywork session, who struggles to transition between activities, who becomes overwhelmed in communal areas when the home is busy — that young person is not necessarily communicating something about their relational history. They may be communicating something about how their nervous system processes the world, which is a different problem requiring a different kind of response. A formulation that cannot hold both possibilities simultaneously is not a complete formulation.

Autistic young people in residential care are frequently identified late, often after years in which their difficulties have been attributed to everything except their neurology. The masking phenomenon — in which autistic individuals learn to suppress or camouflage their autistic traits in order to meet social expectations — is particularly pronounced among girls and young women, and carries significant costs: exhaustion, anxiety, episodic burnout, and a kind of chronic performance that leaves very little capacity for genuine engagement with the people around them. In a residential home, masking can be almost invisible to staff who are not looking for it. The young person who appears to be coping — who is compliant, who moves through daily routines without obvious difficulty — may be spending enormous energy maintaining an appearance of social competence that is not sustainable. The burnout that eventually follows, sometimes months into an apparently settled period, can look like a sudden and inexplicable deterioration. It is not inexplicable. It is the predictable consequence of a regulatory strategy that has reached its limits. A team that has read this as a placement breakdown, or as evidence of trauma destabilisation, without asking whether something neurodevelopmental is happening, has missed the most useful question available to them.

The practical implications for residential homes are specific, and many of them do not require specialist expertise to implement. Neurodiverse young people are typically well-served by environments that offer high predictability: clear structures, advance notice of changes, consistent routines, spaces that allow sensory regulation rather than requiring sustained social exposure. The communal design of most residential homes — shared living areas, group mealtimes, an expectation of participation in collective activities — can be particularly depleting for autistic young people who find group environments costly rather than neutral. This does not mean the home needs to be redesigned. It means the team needs to understand why a particular young person needs more transition time between activities, why asking them to process an emotionally loaded question in a noisy kitchen is unlikely to produce the conversation anyone wants, why their need for solitude after school is not a safeguarding concern but a regulatory necessity. These are adjustments that cost almost nothing to make. They require observation rather than specialist training: paying close attention to when a young person is genuinely settled and when they are performing settlement, and being curious rather than reassured when the two look similar from the outside.

The case for pursuing formal neurodevelopmental assessment, where the picture suggests it may be warranted, is stronger than the sector currently acts on. Access to assessment is variable — dependent on local waiting lists, on referral decisions, on whether a young person's placing authority treats it as a priority. There is a legitimate tension between advocating for assessment and over-pathologising: the risk of reaching for diagnostic labels to explain behaviour that is being generated by circumstances rather than neurology. This tension is real and worth holding. It should not, however, be used as a reason to avoid asking the question. A young person who has ADHD and does not know it, whose care plan frames their difficulties entirely in terms of attachment and trauma, who receives therapeutic input calibrated to a formulation that is incomplete — that young person is not being failed by their carers, who are acting in good faith on the information available to them. They are being failed by a system that has not asked the right questions early enough. Residential homes are in a position to raise those questions — in reviews, in conversations with social workers, in reports written for placing authorities — and to hold their formulations with enough intellectual honesty to revise them when new information suggests they should. The young person whose neurodevelopmental needs are finally recognised at seventeen, after years of being managed rather than understood, deserved that recognition much earlier. The home that noticed, and pressed for it, has done something that will outlast the placement.
