Understanding support needs
Neurodivergent people have many strengths, and may also need specific supports to navigate environments designed around neurotypical functioning. Support should be provided on identified need, not on whether a formal diagnosis is in place.
Sensory accommodations
- Adjustable lighting and sensory-aware environments
- Quiet spaces, and tolerance of noise-cancelling headphones
- Permission to use fidget tools or take movement breaks
- Choice over seating and proximity to sensory triggers
Clear communication
- Written information alongside anything said verbally
- Visual schedules and step-by-step instructions
- Advance notice of changes, with an explanation
- Explicit expectations, without requiring inference
Structure & predictability
- Consistent routines and appointment patterns
- Checklists, visual organisers and timers
- Large tasks broken into manageable steps
Time & processing
- Extended time for exams, assessments and appointments
- Flexible deadlines where they can be offered
- Processing time in conversation — silence is not disengagement
- Tools that externalise time, such as visual timers
Executive function
- Planning tools, checklists and reminder systems
- Task breakdown and step-by-step guidance
- Regular check-ins without judgement
- Appointment reminders in more than one format
Learning accommodations
- Assistive technology, including text-to-speech and speech-to-text
- Alternative assessment methods
- Multi-sensory approaches
- Written materials provided in advance
Moving forward together
Embracing neurodiversity means recognising neurological difference as part of human variation rather than a deficit to be corrected. Inclusion requires more than awareness — it requires action: advocating for adjustments, challenging stigma, amplifying neurodivergent voices, and building accessible systems. Adjustments are a duty under the Equality Act 2010, not a courtesy.
When neurodivergence goes unrecognised
The impact of late or missed diagnosis is significant, lasting, and largely preventable.
The cost of going unrecognised
- Years of being told you are lazy, disruptive or difficult
- Depression and anxiety treated without addressing the underlying neurodevelopmental difference
- Decades of masking — performing neurotypicality at considerable cost
- Internalised shame for difficulties that were never a character failing
- Autistic burnout — loss of function after prolonged masking, often misread as depression
- Increased vulnerability to abuse, exploitation and trauma
What changes
- Understanding why things have been hard, and that it was not a personal failure
- Access to appropriate support, adjustments and treatment
- Protection under the Equality Act 2010
- Connection with others who understand
- The possibility of unmasking, and of recovery
- A different narrative: not broken, differently wired
The Solihull Approach
For parents, carers and professionals — behaviour as communication
Containment
- Helping a child feel safe, held and understood
- Responding to the emotional state before managing the behaviour
- Especially important where self-regulation is difficult
Reciprocity
- Attuned, responsive interaction
- Reading and responding to the child’s cues
- Building trust through consistency and warmth
Behaviour management
- Predictable boundaries rooted in relationship
- Reducing conflict by addressing underlying need
- Practical tools that work in real settings
RSD, alexithymia & emotional experience
Rejection Sensitive Dysphoria
Intense, often overwhelming emotional pain triggered by perceived or actual rejection, criticism or failure. Commonly described in ADHD and autism, and frequently mistaken for borderline personality disorder or bipolar disorder.
- The response is disproportionate to the event, but the pain is real — this is not attention-seeking
- Often triggered by perceived criticism, failure or social exclusion
- Can cause avoidance of any situation where failure is possible
- May drive intense people-pleasing to pre-empt rejection
- ADHD medication reduces the intensity for some people
- Note: RSD is a clinically useful descriptive term, not a formal diagnosis in ICD-11 or DSM-5-TR
Alexithymia
Difficulty identifying and describing one’s own emotions. Estimated to affect around half of autistic people, and common in ADHD. It has significant implications for therapy, consultations and relationships.
- Difficulty knowing which emotion is present, or that one is present at all
- Emotions may register as physical sensation rather than a named feeling
- Makes standard talking therapy less accessible without adaptation
- Frequently misread as lacking empathy — it is not the same thing
- Avoid consultations that depend on emotion-labelling; offer scales or written options
- Body-based and somatic approaches can be more accessible
Menopause & neurodivergence
The intersection of menopause with ADHD and autism is increasingly discussed in the literature but remains poorly recognised in practice. Hormonal change through perimenopause can affect executive function, sensory sensitivity, emotional regulation and the capacity to mask — often bringing previously managed difficulties to crisis point.
Why it matters clinically
- Oestrogen influences dopamine and serotonin regulation, with plausible effects on ADHD symptoms
- Many women are identified as ADHD or autistic around perimenopause, when long-standing coping strategies stop working
- Perimenopausal symptoms and autistic or ADHD burnout overlap substantially and are readily confused
- Evidence on HRT and ADHD symptoms is emerging rather than established — treat it as a reasonable clinical consideration, not a settled intervention
In practice
- Where a woman in her forties or fifties presents with sudden deterioration in executive function, mood or overwhelm, consider both perimenopause and neurodivergence
- Avoid “just menopause” or “just ADHD” — it may be both, interacting
- ADHD medication may warrant review during hormonal change
- Prescribing decisions should follow NICE NG23 and local formulary guidance
Neurodivergent people & the criminal justice system
Neurodivergent people are overrepresented in the criminal justice system, both as victims and as defendants. Studies consistently report higher rates of autism and ADHD in custodial populations than in the general population.
Key issues
- Police interviews may be inaccessible — accounts can appear inconsistent, affect may appear flat after trauma, and rights may not be understood as stated
- A strong drive to be literal and truthful can work against a person’s own case
- Impulsivity may contribute to offending without full appreciation of consequence
- Neurodivergent people may be more vulnerable to exploitation and coercion into criminal activity
Rights & adjustments
- An Appropriate Adult must be provided for vulnerable suspects under PACE Code C
- Special measures and registered intermediaries can be sought in court
- Courts and prisons have duties under the Equality Act 2010 to make reasonable adjustments
- Liaison and diversion services operate at police stations and courts in England and Wales — ask for a referral
- Disclose a diagnosis, or a suspected one, to the solicitor at the earliest point
Neurodiversity & domestic abuse — the clinical link
An intersection every professional working with either group should understand
Why risk is elevated
- Social communication differences can make manipulation, gaslighting and coercive control harder to identify in real time
- Masking and people-pleasing, developed to navigate a neurotypical world, can prevent disclosure and make abuse feel ordinary
- Difficulty holding contradictory information can make “sometimes loving, sometimes abusive” hard to reconcile
- Sensory and emotional dysregulation may mean abuse is experienced more intensely but reported less clearly
- Reliance on routine and predictability raises the barrier to leaving
- Histories of being disbelieved — by parents, schools, services — reduce the likelihood of disclosure
- Higher rates of financial dependency further reduce options
What to do differently
- Adapt routine enquiry: offer written options, ask direct questions, avoid ambiguity and euphemism
- Flat affect, delayed emotional response, or inability to name a feeling is not evidence that abuse is not serious
- Inconsistency in an account is common and does not indicate dishonesty
- Complete DASH risk assessment, but interpret it with neurodivergent presentation in mind
- Note neurodivergence in MARAC referrals as a factor affecting risk and access
- IDVAs working with neurodivergent survivors need adapted communication
- Safety planning must address routine disruption, sensory safety and communication needs
Post-separation abuse
Abuse continued through children, courts and legal processes is particularly damaging for neurodivergent survivors. Court, multi-agency meetings and formal processes are precisely the environments where they face most difficulty, and perpetrators exploit that.
- DARVO is effective against people whose accounts may appear inconsistent
- Formal, unpredictable, high-demand environments can trigger shutdown or meltdown
- Request special measures early — intermediary, written communication, scheduled breaks
What support should look like
- Domestic abuse services should offer adapted versions of their materials and processes
- Allow additional processing time at every stage — appointment, disclosure, safety planning
- Provide written information as well as verbal, every time
- Ask directly: “Is there anything about how you process information that would help me support you better?”
Monotropism
Monotropism is a theory of autistic cognition developed by autistic researchers including Dinah Murray and Wenn Lawson. It proposes that autistic attention tends to be drawn intensely into fewer channels at a time, with strong resistance to shifting, rather than distributed broadly across many channels at once.
What it explains
- Intense interests — the attention tunnel is deep rather than wide
- Transitions — difficulty shifting attention, particularly when unexpected
- Demand avoidance — demands require shifting the tunnel, which is effortful and anxiety-provoking
- Monotropic split — being pulled in two directions at once is deeply uncomfortable
- Social difficulty — real-time processing across multiple channels is highly demanding
Clinical application
- Accounts for autistic experience more coherently than deficit-based models
- Suggests environmental modification is more effective than social skills training
- Reframes meltdowns, shutdowns and transition difficulty as attention regulation rather than behaviour
- Explains why hyperfocus is productive and why interrupting it is distressing
- A theoretical model with growing support, not an established diagnostic framework
Sleep & neurodivergence
Sleep difficulty is common across autism, ADHD and dyspraxia, and is frequently undertreated or attributed to anxiety and poor sleep hygiene when the driver is neurological.
Common presentations
- Delayed sleep phase — the circadian rhythm is shifted later. Common in ADHD. This is not insomnia; the person can sleep, but not at the expected time
- Difficulty switching off — continued processing of the day, interactions and sensory input after lying down
- Night waking — often related to sensory sensitivity or hyperarousal
- Sensory barriers — temperature, noise, texture and light affecting sleep onset and maintenance
Clinical approach
- Consider neurological factors before defaulting to CBT-I or generic sleep hygiene advice
- Address the sensory environment first — blackout, sound, temperature, weighted bedding
- Review ADHD medication timing, which can significantly affect sleep onset
- Melatonin: prescribing should follow NICE guidance and local formulary. Licensed indications are limited, so any use outside them is off-label and needs to be documented as such
Gender incongruence & neurodivergence
Warrier et al. (2020), using five datasets covering over 600,000 people, found that transgender and gender-diverse individuals were three to six times more likely to be diagnosed as autistic than cisgender individuals. Note the direction of that finding — it is frequently reversed in secondary sources. Studies also report elevated rates of gender diversity within autistic populations. This is a co-occurrence, not a causal relationship in either direction.
Clinical implications
- Do not attribute gender diversity to autism or ADHD, or treat it as a symptom to be resolved
- Do not delay or withhold gender-related support pending a neurodevelopmental assessment — these are separate needs
- Reduced conformity to social gender norms may support earlier, more authentic self-identification. That is not pathology
- Assessments should run in parallel, with communication between teams
- Gender services must adapt for neurodivergent people: written materials, longer appointments, sensory-accessible environments, consistency of clinician
Evidence & services
- Warrier et al. (2020), Nature Communications — the largest dataset to date
- Van der Miesen et al. (2018) — elevated autism rates in gender clinic populations
- Strang et al. (2020) — initial clinical guidelines for co-occurring autism and gender incongruence in adolescents
- Service note: GIDS at the Tavistock closed in 2024. Children and young people’s gender services in England are now delivered through regional NHS services, and the 2024 independent review emphasised assessing co-occurring neurodevelopmental and mental health needs
Mental health & neurodivergence
Differential diagnosis, misdiagnosis patterns, and treatment adaptation
Common misdiagnosis patterns
- Autism recorded as EUPD/BPD — emotional intensity, rejection sensitivity and relational difficulty in women are frequently misattributed
- ADHD recorded as bipolar — mood instability and energy fluctuation misread as cycling
- Autistic burnout recorded as treatment-resistant depression — burnout does not respond to antidepressants in the same way
- Anxiety treated as primary — when it is secondary to the sustained effort of masking
- Demand avoidance recorded as ODD — different underlying drivers, and different interventions
Adapting treatment
- CBT needs adaptation — slower pace, concrete examples, written materials, minimal reliance on metaphor
- Alexithymia can make emotion-focused work inaccessible without an adapted approach
- Group therapy requires neurodiversity-aware facilitation; group social demands are not neutral
- ACT and schema therapy may be more accessible for some people
- Consider autism and ADHD before settling on EUPD, bipolar or treatment-resistant depression
- Peer support from other neurodivergent people has a good evidence base
