NICE ADHD guidance (NG87) updated May 2025 with new diagnostics pathway link. Autism guidelines (CG142 adults, CG170 under-19s) reviewed September 2025 — coexisting mental health and developmental problems sections updated. NHS England mandates learning disability annual health checks from age 14+ (previously 14-17 was optional).
Neurodiversity for GPs: Your Essential Guide
Different wiring, same worth — and yes, the consultation may need a software update
Last Updated: 24 March 2026
What This Page Covers
This page is about recognising, understanding, and safely supporting neurodivergent patients in UK general practice. We focus on consultation adaptation, diagnostic thinking, common co-occurring problems, and safety. You'll learn how to run neurodiversity-aware consultations, when to suspect ADHD or autism, how to avoid diagnostic overshadowing, and how to coordinate care across the complex landscape of schools, specialists, and community services.
Why This Matters in GP
Neurodiversity belongs in mainstream general practice, not as a niche add-on. Here's why:
📊 It's Common
~5% have ADHD, > 1 in 100 are autistic, yet only 1 in 9 with ADHD are diagnosed. You're seeing neurodivergent patients every day — whether you recognise them or not.
🎭 It's Often Missed
Especially in women, adults, and people who mask. That "anxious" patient? That "chaotic" teenager? That adult with 15 years of "treatment-resistant depression"? Look again.
💬 It Affects Everything
Presentation, communication, engagement, adherence, health outcomes. If you don't adapt your consultation style, you won't get the history. If you don't recognise the pattern, you'll miss the diagnosis.
⚖️ It's Your Responsibility
Reasonable adjustments are a legal requirement under the Equality Act 2010. Annual health checks for learning disability from age 14+ are an NHS England priority. This isn't optional.

Symptom-Based Differential Frameworks
Click each symptom cluster to explore differential diagnoses
| Condition | Key Features | How to Distinguish |
|---|---|---|
| ADHD | Lifelong pattern, childhood onset, multiple settings, inattention + hyperactivity/impulsivity | Symptoms present before age 12, pervasive across contexts, functional impairment, family history common |
| Anxiety | Worry-driven distraction, rumination, physical symptoms (palpitations, sweating) | Concentration improves when anxiety treated, situational triggers, no childhood history of ADHD symptoms |
| Depression | Low mood, anhedonia, fatigue, psychomotor slowing, poor concentration as part of depressive syndrome | Mood symptoms predominate, episodic rather than lifelong, responds to antidepressants |
| Sleep Disorder | Daytime sleepiness, fatigue, poor concentration due to sleep deprivation | History of poor sleep (insomnia, OSA, shift work), improves with sleep hygiene/CPAP |
| Thyroid | Hypothyroid: fatigue, weight gain, cold intolerance. Hyperthyroid: anxiety, tremor, weight loss | TFTs abnormal, systemic symptoms, responds to thyroid treatment |
| Substance Use | Cannabis, alcohol, stimulants — can mimic or worsen ADHD symptoms | Temporal relationship with substance use, improves with abstinence |
| Autism | Difficulty concentrating on non-preferred tasks, hyperfocus on interests, sensory overload | Social communication difficulties, repetitive behaviours, sensory sensitivities, rigid thinking |
⚠️ Co-occurrence is common: ADHD + anxiety, ADHD + depression, ADHD + autism. Treat all conditions. Don't assume one explains the other.
| Condition | Key Features | How to Distinguish |
|---|---|---|
| Autism | Lifelong social communication difficulties, repetitive behaviours, sensory sensitivities, rigid thinking | Developmental history, pervasive across contexts, doesn't improve with exposure, prefers routine/sameness |
| Social Anxiety | Fear of negative evaluation, avoidance of social situations, physical anxiety symptoms | Wants social connection but fears judgment, improves with CBT/SSRIs, no repetitive behaviours or sensory issues |
| Schizoid Personality | Prefers solitude, limited emotional expression, no desire for relationships | Content with isolation (vs autistic people who may want friends but struggle), no sensory/communication difficulties |
| Hearing Impairment | Difficulty following conversation, asks for repetition, struggles in noisy environments | Audiometry abnormal, improves with hearing aids, no repetitive behaviours or rigid thinking |
| Language Disorder | Difficulty understanding or using spoken language, not explained by hearing loss | Language-specific difficulties, no social motivation problems, no sensory sensitivities |
| ADHD | Interrupts, talks excessively, doesn't listen, impulsive social behaviour | Wants social connection, understands social rules but struggles to follow them due to impulsivity |
| Trauma/Attachment | Difficulty trusting, hypervigilance, avoidance, relationship difficulties due to past trauma | History of abuse/neglect, PTSD symptoms, improves with trauma-focused therapy |
Masking: Many autistic people (especially women) mask their difficulties in social situations. They may appear socially competent but find it exhausting. Ask about "social hangover" — needing days to recover after social events.
| Condition | Key Features | How to Distinguish |
|---|---|---|
| ADHD | Lifelong pattern of disorganisation, impulsivity, poor time management, forgetfulness | Childhood history, pervasive across contexts, doesn't improve with external structure alone |
| Situational Stress | Recent life events (bereavement, job loss, relationship breakdown) causing temporary chaos | Clear precipitant, previously coped well, improves with time/support |
| Poverty/Social Deprivation | Chaotic life due to external circumstances (housing instability, financial crisis, domestic abuse) | External factors predominate, improves with practical support, no childhood ADHD history |
| Substance Misuse | Chaos driven by addiction — financial, relationship, legal problems | Temporal relationship with substance use, improves with abstinence/treatment |
| Bipolar Disorder | Episodic chaos during manic/hypomanic episodes, interspersed with periods of stability or depression | Episodic rather than lifelong, mood symptoms predominate, family history of bipolar |
| Personality Disorder | Unstable relationships, impulsivity, emotional dysregulation (especially BPD) | Relationship difficulties predominate, self-harm/suicidality, trauma history common |
💊 Co-occurrence: ADHD + substance misuse is very common (self-medication). ADHD + BPD overlaps significantly. Treat both. ADHD medication can reduce impulsivity and improve outcomes.
| Condition | Key Features | How to Distinguish |
|---|---|---|
| Autism | Need for sameness, routines provide comfort, distress with change, special interests | Lifelong pattern, routines are comforting (not distressing), no intrusive thoughts, pervasive social/communication difficulties |
| OCD | Intrusive thoughts (obsessions) drive compulsive behaviours, distress if can't perform rituals | Ego-dystonic (person recognises thoughts are irrational), anxiety-driven, responds to SSRIs/CBT |
| Anxiety Disorder | Repetitive behaviours to reduce anxiety (checking, reassurance-seeking) | Anxiety symptoms predominate, no social communication difficulties, responds to anxiety treatment |
| Tic Disorder | Repetitive movements or sounds, premonitory urge, suppressible briefly | Motor/vocal tics, wax and wane, no cognitive component, no distress with change |
✅ Co-occurrence: Autism + OCD is common. Autistic people have higher rates of OCD. Treat both. SSRIs can help OCD symptoms but won't change autistic traits.
🚨 CRITICAL: Behaviour change in someone with learning disability/autism = physical illness until proven otherwise. Do NOT assume it's "just their condition".
| Cause | Clues | Action |
|---|---|---|
| Pain | Guarding, facial grimacing, self-injury, aggression, sleep disturbance | Full examination, pain assessment tools (Abbey Pain Scale, DisDAT), trial of analgesia |
| Infection | UTI, chest infection, dental abscess — may present as behaviour change only | Urine dip, CXR, dental examination, FBC/CRP |
| Constipation | Very common, often missed. Abdominal pain, distension, overflow diarrhoea | Abdominal examination, PR if indicated, trial of laxatives |
| Medication Side Effects | New medication, dose change, drug interactions | Medication review, check for akathisia (antipsychotics), sedation, anticholinergic effects |
| Sensory Overload | Environmental change, noise, crowds, new people | Identify triggers, reduce sensory input, allow recovery time |
| Mental Health | Depression, anxiety, psychosis — may present atypically | Mental health assessment, collateral history, consider specialist referral |
| Safeguarding | Abuse, exploitation, bullying — behaviour change may be only sign | Safeguarding assessment, speak to patient alone, involve safeguarding team |
| Condition | Key Features | How to Distinguish |
|---|---|---|
| Tic Disorder | Sudden, rapid, recurrent movements/sounds, premonitory urge, suppressible briefly, wax and wane | Childhood onset, stereotyped, relieved by performing tic, worse with stress/excitement |
| Tourette's | Multiple motor tics + ≥1 vocal tic, >1 year duration, onset <18 years | Coprolalia (swearing) only in 10%, co-occurring ADHD/OCD common |
| Stereotypies (Autism) | Repetitive movements (hand-flapping, rocking, spinning), self-soothing, no premonitory urge | Longer duration, rhythmic, comforting (not distressing), part of autism presentation |
| Myoclonus | Sudden muscle jerks, no premonitory urge, not suppressible | Neurological cause (epilepsy, metabolic, degenerative), EEG abnormal |
| Chorea | Irregular, flowing, dance-like movements | Sydenham's (post-strep), Huntington's, drug-induced (antipsychotics, levodopa) |
| Akathisia | Inner restlessness, need to move, pacing, rocking | Antipsychotic side effect, distressing, improves with dose reduction/propranolol |
| Functional | Variable, distractible, inconsistent, may have psychological stressors | Diagnosis of exclusion, neurology review, MDT approach |
Management: Most tics don't need treatment. Reassure patient/family. Treat if severe or causing distress. First-line: habit reversal therapy (CBT). Medications: clonidine, guanfacine, antipsychotics (specialist only).
⚠️ Key Point: Neurodivergent people have 3-4x higher rates of depression/anxiety. Treat both conditions. Don't assume depression explains everything.
| Scenario | Clues | Action |
|---|---|---|
| Depression + ADHD | Lifelong concentration difficulties, recent onset low mood, anhedonia, sleep/appetite change | Treat depression (SSRIs/therapy), refer for ADHD assessment, treat both |
| Depression + Autism | Lifelong social difficulties, recent onset low mood, may present atypically (increased rigidity, meltdowns) | Treat depression (adapted CBT, SSRIs), autism-friendly communication, reasonable adjustments |
| Undiagnosed ADHD | Years of "treatment-resistant depression", actually unrecognised ADHD causing low self-esteem/failure | Take developmental history, screen for ADHD, refer for assessment |
| Autistic Burnout | Exhaustion from masking, sensory overload, social demands. Looks like depression but different | Reduce demands, increase support, reasonable adjustments, rest, NOT antidepressants alone |
| Situational | Clear precipitant (bullying, unemployment, relationship breakdown), improves with support | Practical support, signposting, brief intervention, monitor |
✅ Treatment Adaptations: Standard depression treatment works for neurodivergent people BUT may need adaptations: longer appointments, written information, autism-adapted CBT, ADHD medication can improve mood by reducing functional impairment.
Condition-Specific Management
Click each condition for detailed management guidance
Prevalence: ~5% of children, ~2.5% of adults. Male:female ratio 3:1 in children, 1:1 in adults (women underdiagnosed). Only 1 in 9 people with ADHD are diagnosed in UK.
Prevalence: >1 in 100 UK population. Male:female ratio ~3:1 (women underdiagnosed due to masking). Lifelong neurodevelopmental condition affecting social communication and behaviour.
🚨 CRITICAL: People with learning disabilities die 15-20 years younger than general population, mostly from preventable causes. Annual health checks from age 14+ are MANDATORY and save lives.
Definition: Motor coordination difficulties affecting daily activities. Clumsy, poor handwriting, difficulty with sports, dressing, using cutlery. Prevalence ~5-6% of children.
Definition: Difficulty with reading, writing, spelling despite normal intelligence. Prevalence ~10%. Highly heritable.
Definition: Sudden, rapid, recurrent movements (motor tics) or sounds (vocal tics). Tourette's = multiple motor + ≥1 vocal tic, >1 year, onset <18 years.
High-Risk Scenarios
Click each red flag for detailed assessment and management
🚨 CRITICAL: Neurodivergent people have 3-9x higher suicide rates. Autistic people without learning disability have 9x higher suicide rate. ADHD + impulsivity = high risk of impulsive self-harm.
Risk Factors
Assessment
Ask directly: "Are you having thoughts of harming yourself?" "Have you made plans?" "Do you feel safe right now?" Direct questions don't increase risk — they save lives.
⚠️ Atypical Presentation: Autistic people may not express suicidal ideation in typical ways. Look for behaviour change, withdrawal, giving away possessions, sudden calmness after period of distress.
Management
🚨 HIGH RISK GROUP: Neurodivergent people (especially learning disability, autism) at higher risk of abuse, exploitation, neglect. Low threshold for safeguarding referral.
Types of Abuse
Red Flags
⚠️ Behaviour change: Withdrawal, fear, aggression, self-harm, sleep disturbance. May be only sign of abuse in non-verbal patients.
Action
Speak to patient alone: Ask carer to leave room. Use simple language. "Are you safe at home?" "Is anyone hurting you?" Document verbatim.
🚨 DIAGNOSTIC OVERSHADOWING TRAP: Behaviour change in learning disability/autism = physical illness until proven otherwise. Don't assume it's "just their condition".
Common Missed Diagnoses
Assessment
Full examination: Don't skip physical examination. Look for signs of pain (guarding, facial grimacing), infection (fever, tachycardia), constipation (abdominal distension).
⚠️ Pain assessment tools: Abbey Pain Scale, DisDAT (Disability Distress Assessment Tool). Use for non-verbal patients.
Investigations
⚠️ Definition: Sudden or gradual loss of previously acquired skills. Can't cope with daily activities that were previously manageable. Common at transition points.
Causes
Assessment
Exclude physical illness: Full examination, bloods (FBC, TFTs, B12, glucose), urine dip. Don't assume it's "just stress".
💊 Mental health assessment: Depression, anxiety, psychosis. Use adapted tools. Collateral history essential.
Management
⚠️ High Risk: ADHD + substance misuse is very common (self-medication for symptoms). Autistic people may use substances to cope with social anxiety, sensory overload.
Patterns
Assessment
Screen routinely: AUDIT (alcohol), DAST (drugs). Ask non-judgmentally. "Do you use anything to help you cope/relax/concentrate?"
Management
🚨 Don't Miss: New onset seizures, status epilepticus, acute neurological deficit, raised ICP. Epilepsy prevalence 30% in learning disability, 20-40% in autism.
Red Flags
🚨 Shocking Statistics: People with learning disabilities die 15-20 years younger. 40% of deaths are from preventable causes. Diagnostic overshadowing kills.
Common Missed Diagnoses
Prevention
✅ Annual health checks: Mandatory from age 14+ for learning disability. Proactive screening, early detection, health action plan.
Referral Pathways & MDT Working
Click each service for referral criteria and coordination tips
Service Structure
Referral Criteria
Include in referral: Developmental history, school reports, collateral history, screening tool results (ASRS), functional impairment examples, co-occurring conditions, medication history.
Waiting Lists
⚠️ Often 1-3 years. While waiting: treat co-occurring conditions, reasonable adjustments, signpost to charities, workplace/education liaison. Right to Choose (England) — patient can choose alternative provider.
Shared Care
Service Structure
Referral Criteria
Include in referral: Developmental history, AQ-10 score, collateral history (essential), functional impairment examples, co-occurring conditions, school reports if available.
Waiting Lists
⚠️ Often 1-3 years. While waiting: start reasonable adjustments NOW (don't wait for diagnosis), treat co-occurring conditions, signpost to National Autistic Society.
Team Composition
Referral Criteria
SENCO = Special Educational Needs Coordinator. Every school has one. They coordinate support for children with SEN.
GP Role
Red Flags
🚨 School exclusions: High rate in neurodivergent children. Often due to unmet needs. Advocate for support, not punishment. Exclusion worsens outcomes.
Key Partners
Coordination Tips
✅ Be the coordinator: Neurodivergent patients often fall through gaps between services. GP is often best placed to coordinate care, advocate, and ensure continuity.
Simple Changes, Big Impact
These adjustments help everyone, not just neurodivergent patients. Clear communication, longer appointments, reduced sensory overload — these are just good practice.
📝 AKT Pearls
ADHD diagnosis requires: Symptoms before age 12, ≥2 settings, functional impairment, not better explained by another condition.
✅ Autism core features: Social communication deficits + restricted/repetitive behaviours. Sensory sensitivities common but not required for diagnosis.
⚠️ Learning disability: IQ <70 + adaptive functioning deficits + onset before adulthood. Annual health checks mandatory from age 14+.
💊 ADHD medication: Methylphenidate first-line (children/adults). Lisdexamfetamine alternative. Atomoxetine if stimulants contraindicated.
🚨 Diagnostic overshadowing: Behaviour change in learning disability/autism = physical illness until proven otherwise. Don't assume it's "just their condition".
🎭 SCA Scenarios
Scenario 1: Adult ADHD
35-year-old with lifelong concentration difficulties, job-hopping, relationship problems. Suspects ADHD. Take developmental history, use ASRS, collateral history, refer for assessment.
Scenario 2: Autistic Burnout
Diagnosed autistic adult, sudden functional decline. Exclude physical illness, reduce demands, reasonable adjustments, treat co-occurring depression.
Scenario 3: Behaviour Change
Learning disability patient, sudden aggression. Don't assume it's "just their condition". Full examination, pain assessment, urine dip, medication review.
Scenario 4: Reasonable Adjustments
Autistic patient struggling with appointments. Offer longer appointments, written information, reduce sensory overload, don't force eye contact.
📋 WPBA Ideas
COT: ADHD Assessment
Consultation with suspected ADHD. Developmental history, ASRS, collateral history, functional impairment, referral letter.
CbD: Annual Health Check
Learning disability annual health check. Physical examination, bloods, screening, mental health, epilepsy review, health action plan.
DOPS: Autism Communication
Consultation with autistic patient. Clear communication, written information, reasonable adjustments, sensory considerations.
SEA: Diagnostic Overshadowing
Reflect on case where physical illness was initially missed due to diagnostic overshadowing. Learning points, system changes.
QI Project: Reasonable Adjustments
Audit reasonable adjustments in practice. Implement changes (flagging system, longer appointments, staff training). Re-audit.
💪 You're Already Doing More Than You Think
Every time you book a longer appointment, use clear language, or adapt your consultation style, you're making a difference. Reasonable adjustments aren't "special favours" — they're good medicine.
🧠 You Don't Need to Be an Expert
Your job isn't to diagnose everything or know all the answers. It's to recognise patterns, adapt consultations, coordinate care safely, and refer appropriately. You're doing great.
🤝 Small Changes, Big Impact
Flagging records, offering first appointments, providing written summaries — these tiny changes transform patient experience. You don't need a specialist clinic to be neurodiversity-friendly.
🎯 Remember the Basics
Behaviour change = physical illness until proven otherwise. Annual health checks save lives. Treat co-occurring conditions. Don't assume one diagnosis explains everything. You've got this.
🌟 Now go forth and be brilliantly neurodiversity-aware. Your patients will thank you. 🌟
