A note before we begin. I am not a specialist in neurodivergent experience. I am a grief counsellor sitting with what the research is beginning to reveal, and with what I notice in the room. The field is young and honest about its own limits. This essay tries to be honest about them too.
Grief is supposed to be recognisable.
We know what it is meant to look like. The wet eyes at the funeral, the months of slow recovery, the gradual return of ordinary life. There is a script, and most of us have absorbed it so completely that we do not notice it is there until someone fails to follow it.
A flat voice asking factual questions about what happens to a body after death. Laughter in the middle of a condolence conversation. A total inability to open post-bereavement for two months. A research project, conducted at 2 am with the focus of someone building a case into the precise medical details of the illness that took someone.
None of these look like grief. But each of them may be exactly grief, moving through the only nervous system that person has.
I have been reading, with growing attention, the emerging research on what happens when grief moves through a neurodivergent nervous system.
The field is young, and I want to say that plainly. The most significant anchor we have is a 2024 systematic review from the University of Edinburgh, led by Ally Pax Arcari Mair and colleagues, which synthesised 39 studies and lived-experience sources across neurodevelopmental conditions and named its overarching theme “Recognise the Unrecognised”: grief in neurodivergent people frequently goes unseen, especially after non-death losses, and is often misread as challenging behaviour, or as no reaction at all.
There is also a 2023 qualitative study by Corden, Brewer and Cage, one of the few pieces of research to ask bereaved autistic adults directly about their experience. On ADHD and grief, the evidence is close to absent. On dyslexia, dyspraxia, and other neurodivergences, there is almost nothing peer-reviewed at all.
I am not writing from expertise. I am writing from curiosity, and from the conviction that what gets missed matters.
One of the mechanisms that keeps appearing in the autism and grief literature is alexithymia: difficulty identifying and describing one’s own emotional states. Around half of autistic people experience this to a significant degree, though estimates vary considerably by study and measure.
The experience is not the absence of feeling. It is the absence of translation between what the body is doing and what the mind can name.
Grief is substantially a bodily event. A tight chest. A heaviness in the limbs. Appetite that vanishes or doubles. Sleep that does not restore. For someone who reads their body’s signals differently, the body may register catastrophic loss as nausea, as pain, as a sudden intolerance for lights or sound, long before the word grief becomes available.
Rebecca Brewer at Royal Holloway, whose work on interoception and autism is some of the most precise available, helps to explain why. Interoception is the perception of the body’s internal state. Altered interoception does not mean the body is silent. It means the signals come through differently. Sometimes with more noise, sometimes with less resolution. A neurodivergent griever may be flooded with bodily distress they cannot locate as an emotion, or may register almost nothing physically and then be ambushed by the grief later, when it finds a different route in.
This matters clinically. It means that asking “how are you feeling?” may be precisely the wrong question. Something has happened. The body knows. The language has not arrived yet.
There is a second grief in the experience of many autistic people, and the research is only beginning to name it.
A death is not only the loss of a person. It is the loss of a routine, a sensory environment, a source of predictability. The weekly phone call at the same time, every Sunday. The person who could be trusted not to require eye contact. The house that smelled a specific way, that had a texture of light you recognised without thinking.
The 2023 Corden, Brewer and Cage study found that bereaved autistic adults frequently grieved this loss too, and that it was largely invisible to the people around them.
Contemporary understanding of autism places significant weight on the role of predictability in wellbeing. A death is arguably the largest single act of unpredictability a life contains. It deletes routines, roles, and futures simultaneously. For an autistic person, this may produce two concurrent griefs: the grief of losing the person, and the grief of losing the world that person helped hold stable. The second is real, and it is rarely named.
Asking “what else died with them?” is not a metaphorical flourish in this context. It is assessment.
Bereavement in the UK also arrives with an exam attached.
Register the death. Arrange the funeral. Notify every institution. Handle probate. Manage a hundred low-stimulation administrative tasks with serious consequences for delay or error.
Both autism and ADHD involve differences in executive function: the capacity to plan, initiate, switch, and hold information in working memory while doing something with it. Grief disrupts these functions for anyone. For neurodivergent grievers, there is a compounding effect. The executive load of bereavement sits on a system that was already working harder than most people realise, and it can produce paralysis, missed deadlines, and unopened envelopes that look, from outside, like avoidance or indifference.
One of the very few studies to examine ADHD and grief directly, a doctoral dissertation from Antioch University, described this plainly: the combination of emotional dysregulation and practical overwhelm can leave people concluding they are failing at grief, when they are actually managing an executive function crisis that happens to be wearing grief’s clothes.
Shame tends to follow. And shame is expensive.
Damian Milton, a sociologist at the University of Kent, introduced the concept of the double empathy problem: the observation that misunderstanding between autistic and non-autistic people runs in both directions. Neurotypical observers are, on average, poor at reading neurodivergent emotional expression.
Applied to grief, this predicts exactly what the research and lived-experience accounts consistently describe. Flat affect is read as coldness. Laughter is read as disrespect. Factual questions are read as not caring. Repeated questions are read as failure to understand the situation. Each of these may be exactly how grief is working in that person. None of them means the person is not grieving.
The 2023 bereavement study found that autistic participants frequently masked their grief in public: maintaining the expected social performance at cost, with the grief surfacing privately later, often much later. The most skilled maskers were the most invisible to the people around them.
The counselling room may be the first place the mask has been allowed to come off.
I want to be honest about the limits of what I know here.
The research is genuinely still in early stages. The 2024 Edinburgh systematic review is the best single anchor available, and even it is working from a relatively small evidence base. On ADHD and grief specifically, almost no peer-reviewed empirical research exists. On the other neurodivergences, even less. The differences I have described in this essay are each individually well-evidenced. Their specific interaction with bereavement is mostly not yet measured.
And I am aware that this essay exists in a world where neurodivergent people have spent considerable time being told that their emotional responses are wrong, too much, not enough, or simply misunderstood. I do not want to add another layer of theory to that.
What I am confident in is narrower and more important than a comprehensive theory of neurodivergent grief.
Grief moves differently through different nervous systems. The way a person is wired shapes how loss is felt, expressed, and timed. When grief does not match the expected script, it tends to get missed, dismissed, or pathologised.
That gets in the way of people being supported. It also gets in the way of them supporting themselves, because if your grief does not look like grief, it is very hard to give yourself permission to take it seriously.
I do not know if you are reading this as a neurodivergent person, or as someone who loves one, or as a practitioner sitting with questions about how standard grief models are failing some of the people who need them most, or as someone who has simply watched their own grief fail to follow the expected map and wondered what that meant.
Any of those is a legitimate reason to be here.
What I can say is this: your way of grieving is a way of grieving. The fact that it does not look like the picture does not mean it is not real, or that it does not deserve space.
The body knows before the mind does. Sometimes the kindest thing anyone can do is stop asking the mind to translate, and simply believe the body.
