Autism Spectrum Disorder

This course exists partly because of Oliver McGowan, a young man who died in 2016 after being given anti-psychotic medication — despite Oliver and his parents repeatedly warning staff that he had reacted badly to this type of drug before. The medication caused severe brain swelling, and he did not survive. His mother, Paula, has since campaigned to make learning disability and autism training compulsory for every health and social care worker, and that campaign succeeded.

Oliver's family believe that if the staff caring for him had properly understood autism and learning disabilities — and how these can interact with seizure activity — his care would have been managed very differently. His story is the reason the Oliver McGowan Mandatory Training on Learning Disability and Autism now exists, and why the Health and Care Act 2022 requires all relevant staff to complete training suited to their role.

The mandatory training has two parts: everyone completes an e-learning module, and then either Tier 1 (a one-hour interactive online session for staff who need general awareness) or Tier 2 (a full day of face-to-face training for staff who directly provide care and support). Both tiers are co-delivered by a person with a learning disability and an autistic person alongside a facilitator or trainer — lived experience sits at the centre of the training, not just theory.

Before moving on, it's worth watching the official explainer video on why this training matters: Oliver's Training — the story behind the training.

Autism Spectrum Disorder (ASD) is a lifelong developmental condition that shapes how someone communicates with, and relates to, other people and the wider world. It's thought to affect roughly 1 in 100 people — around 700,000 people across the UK — and while it can't be "cured", the right support makes a genuine difference to someone's quality of life.

"Spectrum" is the key word: no two autistic people experience the condition the same way. Some also live with a learning disability or epilepsy alongside their autism, which is exactly why flexible, individualised care matters so much — a rigid, one-size-fits-all approach simply doesn't work here.

You may still hear older terms like Asperger's Syndrome, Pervasive Developmental Disorder, or Autistic Disorder — these have now all been folded into the single umbrella term Autism Spectrum Disorder, although people diagnosed under the older terminology often still identify with it.

As a care worker, your job is to communicate in whatever way works for the individual in front of you, notice when someone is becoming stressed or anxious, and know when a situation calls for more specialist input than you can provide alone.

A few essential facts to hold onto

• Autism is considered a neurodevelopmental condition — it's part of how someone's brain is wired, not an illness to be treated away
• There's no cure, and there doesn't need to be one for someone to live a full life
• There's likely a genetic element, meaning it can run in families
• Sensory experience is often very different — over- or under-sensitivity to touch, taste, smell, sound, light or colour is common

Around 2.8 million people in the UK are affected by autism either directly or through a close friend or family member's diagnosis — it's far more common than most people assume, even though it remains an invisible disability to the casual observer.

Autistic people share some common ground, but the condition still touches every individual differently — and it often brings barriers that aren't obvious from the outside.

• The world can feel overwhelming, which often shows up as anxiety
• Heightened sensitivity to certain senses can tip into sensory overload
• Reading other people and joining in socially can be genuinely hard work, sometimes leading someone to withdraw or act in ways that look "antisocial"
• Most people without autism pick up on social cues almost automatically — this instinctive reading of a room is exactly what many autistic people find most difficult, which can leave them feeling like an outsider
• Without knowing someone is autistic, it's easy to misread their behaviour as deliberate misbehaviour, when really they're just trying to process an overwhelming amount of information

An early, accurate diagnosis makes it far easier to put the right support in place.

A short reflection for you as a care worker

Think honestly about your own experience so far: which of the following are you already comfortable with, and where do you feel least confident?

• Adjusting how you communicate to suit an autistic person's needs
• Drawing on family and friends' knowledge of the person you're supporting
• Spotting stress or anxiety early, and responding well
• Recognising someone's sensory needs and adjusting accordingly
• Helping someone build social skills or cope with big life transitions
• Understanding how autism and mental illness can overlap
• Supporting someone into or within employment

Understanding where our current knowledge of autism came from helps explain why practice keeps evolving.

• 1943 — Leo Kanner published the first description of what would become known as classic autism. Research since then has steadily widened the concept of autism spectrum disorders, which is part of why estimated prevalence has risen over time.
• 1966 — Victor Lotter's epidemiological study of children matching Kanner's description found a prevalence of 4.5 per 10,000.
• 1979 — Lorna Wing and Judith Gold studied children with special needs and confirmed Lotter's rate among children with an IQ under 70 — but also identified a much larger group (roughly three times as many) with a broader mix of difficulties in social interaction, communication and imagination. This gave rise to the phrase "triad of impairments," and the recognition that autism extends well beyond Kanner's original, narrower description.

Separately, later research painted a fuller picture of adult life with autism: a 2009 Act of Parliament (the Autism Act) led to a huge expansion in diagnostic services for autistic adults in England — from almost none, to coverage in 93% of areas within a decade. Even so, a 2012 study found 70% of autistic adults weren't getting the social care support they needed, one in three were experiencing serious mental health difficulties as a result, and only 15% were in full-time paid work. Isolation carries a real health cost too — research from the Campaign to End Loneliness found its impact on health comparable to smoking 15 cigarettes a day.

PDA sits within the autism spectrum and shares some traits with other forms of autism, but its defining feature is different: an anxiety-driven need to stay in control, which shows up as avoiding everyday demands and expectations. Specialist Dr Judith Gould's work on the DISCO diagnostic framework helped identify which traits are most distinctive to PDA specifically.

The features that tend to stand out

• Appearing sociable on the surface, without the deeper social understanding that usually goes with it
• Resisting or avoiding ordinary daily demands
• Being unusually comfortable with role play or pretend scenarios, sometimes to an intense degree
• Impulsivity and pronounced mood swings
• Obsessive behaviour, often centred on particular people
• Delayed language development that often catches up significantly later on

Like every form of autism, PDA is a spectrum in itself — no two people are affected identically or to the same degree.

Children with PDA often have stronger communication and social awareness than people with other forms of autism — but this can be double-edged. Empathy and social understanding are often present, but mostly on the child's own terms, which can come across as superficial. A strong need to be "in charge" often causes friction with siblings and peers, and the child may relate to adults almost as equals rather than accepting a junior role in the household.

Avoidance of everyday demands can become extreme, and meltdowns driven by panic are common, especially in children — often taking far more energy to resist a task than it would have taken to simply do it.

Everyday routines — getting dressed, washing, brushing teeth, wearing a seatbelt, holding hands while out walking — can all become flashpoints.

Many children with PDA have vivid imaginative play, inventing whole characters and storylines for toys and games — sometimes so vividly that the line between fantasy and reality blurs, such as covering a doll's ears "so it can't hear."

In school settings, a consistent keyworker who builds a close understanding of the child — knowing when to push gently and when to back off — tends to work far better than a rotating cast of staff.

Diagnosis in childhood

A diagnosis can feel frightening for parents, but it also brings clarity — explaining behaviours that had previously seemed puzzling, and opening the door to the right support as the child grows. Some parents instead choose an informal "self-diagnosis" route, understanding the condition without seeking a formal label — there's no single right answer here, and a parent's wishes should be respected until the child is old enough to make that decision for themselves.

Signs that often prompt a parent — or a professional — to consider a diagnosis include repetitive routines (playing the same game, lining objects up precisely), not pointing things out to share interest the way other children do, strong resistance to change, emerging difficulties with social interaction or communication, and challenging behaviours such as self-injury, biting, or putting inedible objects in the mouth (pica).

Concerns should always be raised sensitively — if you're ever unsure how to approach this, speak to your supervisor first. Parents can seek a diagnosis via their GP, health visitor, or a specialist service such as the National Autistic Society. Once a GP agrees there's cause for concern, a multi-disciplinary team carries out a full assessment — typically including a school or nursery report, a medical examination, observations across different settings, a developmental and family history specific to autism, and an assessment of family strengths and needs. If the child is school-age, a Special Educational Needs Co-ordinator (SENCO) is usually involved too. Every test is explained clearly, and a full written report follows.

Diagnosis in adulthood

Not everyone is diagnosed as a child. Many adults recognise themselves in something they've read or seen about autism later in life. As with children, a GP is the first step — the adult will usually need to explain why they suspect they may be autistic, and what they hope to gain from a formal diagnosis (usually access to formal support). If the GP agrees it's worth pursuing, they're referred to a local specialist service. Adult diagnosis is typically carried out by a psychiatrist or clinical psychologist, without a physical exam or blood tests, usually following a structured interview under the DISCO framework.

Symptoms vary enormously between individuals, but three areas consistently present a challenge: social communication, social interaction, and restricted or repetitive behaviours and interests.

Social communication

Reading body language and unspoken social cues can feel like decoding an unfamiliar language. Many autistic people take language literally, assuming others mean exactly what they say — which makes sarcasm, jokes, and tone-dependent meaning genuinely hard to interpret, since the true message often lives in a facial expression or vocal tone rather than the words themselves.

Speech

Speech itself can be limited, or absent altogether, for some autistic people. It's common to understand far more than you can express — which can be deeply frustrating. Alternative communication — sign language, visual symbols, or other methods — can bridge that gap effectively. Take the time to learn how each person prefers to communicate, speak clearly and consistently, and give people enough time to process what's been said before expecting a response. Even someone with strong verbal skills may still struggle with the unwritten rules of conversation — echoing back what's said to them, or talking at length about a favourite topic without registering that the other person has lost interest.

Social interaction

Recognising and responding to other people's emotions — and expressing their own — can be genuinely difficult. What looks like insensitivity is usually just a missed emotional cue, not indifference. Feeling overloaded often leads someone to seek solitude rather than try to untangle someone else's feelings. Most autistic people do want friendships and connection — the barrier is usually skill and confidence, not desire, and the result can be real isolation.

Restricted or repetitive behaviours and interests

Because an unpredictable world can feel overwhelming, routine and repetition offer a sense of control — the same route to school, the same meals, particular clothing preferences (especially where sensory issues are involved), and once something is learned as "the right way," alternatives can feel simply wrong, however reasonable they are. Deeply focused interests, often formed early and lasting a lifetime, are frequently central to someone's sense of wellbeing. Getting to know someone well — including any medical routines that might disrupt their day — makes it much easier to support them through necessary change.

Sensory sensitivity shows up in one sense or several, and it usually runs in one of two directions: hyper-sensitivity (senses feel far too intense) or hypo-sensitivity (senses barely register at all). Background noise most people filter out automatically — conversations, traffic, electronic beeps — can become impossible to ignore for a hyper-sensitive person, sometimes triggering real anxiety or even physical pain. A hypo-sensitive person, meanwhile, may not register pain or extreme temperature — early warning signs of injury that most of us rely on without thinking. Rocking, spinning, or hand-flapping ("stimming") is a common way of self-regulating during sensory overload or stress, and sensory differences can also affect spatial awareness — misjudging distances from furniture or other people, or finding fine motor tasks like buttons and shoelaces harder than expected.

Many autistic people also live with other conditions that shape daily life well beyond formal education — including how they learn everyday tasks like cooking or washing. Support needs vary hugely: some people live independently with light support, others need much more throughout their life. ADHD, dyslexia and dyspraxia are particularly common alongside autism, and are worth understanding further if you're supporting someone with any of these alongside their autism.

Three areas where sensory and perceptual difficulty often shows up

• Sensory over-sensitivity — reactions range from mild discomfort in a busy, bright environment through to full sensory overload. Triggers vary hugely: intolerance of fluorescent lighting, gagging at certain smells, being unable to cope with sudden loud noise, discomfort with particular food textures or physical touch. Left unaddressed, these triggers can make someone avoid entire places or situations, limiting their opportunities to learn and build coping strategies.
• Perceptual problems — someone with poor auditory perception may experience speech the way you'd experience a bad phone line, with words fading in and out; sharing information visually instead can help. Someone with visual processing difficulties might read from the corner of their eye, flick their fingers in front of their eyes, or feel anxious around fluorescent lighting and escalators — for them, the visual world can feel fragmented, like looking through a kaleidoscope, or narrowed to a small circle with no peripheral vision at all. Physically guiding someone's hands through a task, or letting them trace shapes and use 3D objects, is often more effective than showing or telling.
• Difficulty organising information — speech can sometimes dissolve into meaningless noise, and multi-tasking becomes genuinely difficult because flexible thinking is harder. This, like sensory processing, gets noticeably worse the more tired someone is.

Helping an autistic person manage anxiety, both mentally and physically, is a core part of your role. Helping someone recognise and name what they're feeling — and understand why — puts them in a much stronger position to manage it. Speak to your line manager if you'd like further training in this area.

Psychological signs

• Difficulty concentrating
• Losing patience quickly
• Fixating on worst-case outcomes
• Becoming preoccupied or obsessive about a subject
• Poor or disrupted sleep
• Low mood
• Reduced appetite

Physical signs

• Stomach pain or diarrhoea
• Excessive thirst or a dry mouth
• Sweating, especially the palms
• Needing the toilet more often
• A racing or pounding heartbeat
• Aching muscles, dizziness or headaches
• Trembling hands or other tremors

Many of these can also be side effects of unrelated conditions or medication, so it's worth genuinely getting to know the person and ruling out other causes before working through anxiety-specific strategies together.

Challenging behaviour — physical aggression or other behaviour that harms the individual or people around them — is common among autistic people, and strategies typically need to cover self-injury, physical behaviours (biting, hitting, spitting, hair-pulling), pica, and smearing.

Why it happens

Challenging behaviour is very often a form of communication — the only way someone feels able to express difficulty processing information, coping with unstructured time, managing over- or under-stimulation, adjusting to a change in routine or environment, or dealing with pain, illness, tiredness or hunger they can't otherwise put into words. Frustration builds, and it comes out as behaviour rather than speech.

Using a behaviour diary

Recording what happens before, during and after an incident helps you spot triggers and purpose over time — who was present, what changed, how the person seemed to feel. Patterns often only emerge after a few weeks of consistent recording, but once you can "decode" a behaviour, you can start working out how to prevent the trigger causing distress next time.

Practical approaches

• Communication — use short, simple language; support the person to express needs, wants, pain or discomfort in whatever way they communicate best (speech, sign, images, visual props); allow plenty of time to process before expecting a response
• Rewards — positive reinforcement for the behaviour you want to encourage helps someone understand expectations; get to know the person well enough to choose rewards and praise that genuinely mean something to them
• Relaxation — essential oils, massage, calming music, or gentle activity like swinging can all support healthy emotional regulation
• Physical release — challenging behaviour sometimes comes from pent-up energy rather than emotion; running around a garden, skipping, a punching bag, or a trampoline can release that energy before it turns into a bigger issue
