Understanding autism

Some parents still have old reports tucked away in drawers with terms like PDD or PDD-NOS written across the top. Then years later, they hear different language around autism and suddenly start wondering whether they have misunderstood everything somehow. Whether the diagnosis still “counts”. Whether they are using the wrong terminology. Whether everybody else got some updated handbook they missed. It happens far more often than people realise. PDD stood for Pervasive Developmental Disorder . PDD-NOS meant Pervasive Developmental Disorder – Not Otherwise Specified . Years ago, these terms were often used when a child showed autistic traits or developmental differences, but did not fit neatly into the narrower autism categories being used at the time. Today, most children who may previously have received a PDD or PDD-NOS diagnosis would now fall under the broader Autism Spectrum Disorder umbrella. But the language changing does not erase the child standing in front of you. What parents often noticed first For most families, it was never really about the terminology in the beginning anyway. It was: the child who became overwhelmed by noise the child who struggled socially in ways nobody could fully explain the child who seemed completely fine one moment and overloaded the next the child who melted down after school every day the child who copied other children constantly just to keep up the child who seemed anxious all the time underneath the surface the child who felt “different” long before anybody had language for why Some children were highly verbal and academically capable but still struggling enormously underneath. Others had uneven developmental profiles that confused the adults around them. A lot of parents knew something was different long before anybody gave it a name. Why the terminology changed Years ago, autism diagnoses were divided into several separate categories, including: Asperger’s Syndrome Autistic Disorder PDD-NOS Childhood Disintegrative Disorder Over time, professionals realised these categories overlapped heavily and often did not reflect how autism actually presents in real life. Some children moved between labels depending on who assessed them. Others did not fit neatly into one category at all. That is one reason the broader Autism Spectrum Disorder diagnosis is now used more commonly. For parents, though, the change in language can sometimes feel unsettling. Especially when: older reports still use PDD-NOS schools use outdated terminology online information contradicts itself different professionals explain things differently family members question whether the diagnosis is “serious enough” That confusion is understandable. What PDD-NOS often looked like Children previously described as having PDD-NOS often showed autistic traits in ways that looked more subtle, uneven or inconsistent than people expected at the time. A child may have: struggled socially but seemed highly verbal managed academically while battling emotionally become overwhelmed by sensory input struggled badly with change or unpredictability copied peers socially to blend in experienced intense anxiety missed social cues seemed “quirky” or “different” without fitting older stereotypes of autism Many children who received this label were intelligent, observant and highly aware of the world around them, but still struggling to navigate environments that felt exhausting, confusing or overwhelming. What is often misunderstood One of the hardest things for many families is that children with more subtle or uneven presentations are often misunderstood for years. Children may be described as: anxious dramatic immature controlling overly sensitive socially awkward perfectionistic difficult Sometimes adults focus only on the behaviour they can see without recognising the stress sitting underneath it. A child who melts down after school may have spent the entire day masking. A child who seems rigid may actually be trying desperately to create predictability in a world that feels chaotic. A child who struggles socially may not lack interest in friendship at all. They may simply be exhausted by how much processing social interaction requires. Often, there is far more happening beneath the surface than people realise. School and hidden effort School can be particularly difficult for children with uneven autism profiles because outward performance does not always reflect internal effort. A child may: achieve good marks while struggling socially appear calm in class but collapse emotionally at home become overwhelmed by noisy classrooms or group work mask anxiety throughout the day struggle badly with transitions or unpredictability spend huge amounts of energy trying not to “get things wrong” Sometimes the child who seems fine is actually surviving through constant compensation. Helpful support at school may include: predictable routines sensory-aware environments reduced overwhelm where possible processing time calm communication flexibility around participation emotional support understanding around masking and exhaustion Children usually cope far better once adults stop focusing only on outward behaviour and start noticing the effort underneath it. At home Home is often where all the held-togetherness finally gives way. Parents may see: meltdowns after school withdrawal irritability shutdowns anxiety emotional exhaustion rigidity around routines overwhelm over things that seem tiny from the outside This can feel deeply confusing when the child appeared completely fine earlier in the day. But many children are spending enormous amounts of energy simply trying to get through environments that feel socially, emotionally and sensory overwhelming. Home often becomes the place where all that hidden effort finally spills over. Strengths and capacity Children previously labelled with PDD or PDD-NOS are individuals first. Many are thoughtful, creative and deeply observant. Some notice patterns other people miss completely. Others develop extraordinary depth around the things they love and care about. Many also show strengths in: creativity deep focus honesty memory problem-solving specialist interests original thinking attention to detail At the same time, strengths do not erase support needs. A child can be bright, verbal and academically capable while still struggling enormously with anxiety, sensory overload, emotional regulation or social exhaustion. Both things are often true at the same time. When to seek support If a child is consistently struggling with sensory overwhelm, emotional regulation, social interaction, anxiety or coping with everyday demands, it may help to speak to an appropriately qualified healthcare or educational professional familiar with autism and developmental differences. Assessment is not about reducing a child to a label. For many families, understanding finally brings language to experiences that previously felt confusing or isolating. A final thought If your child received a PDD or PDD-NOS diagnosis years ago, it does not mean you misunderstood them or somehow failed to keep up. The language evolved. Your child did not suddenly become a different person. Sometimes parents become so anxious about saying the “right” thing that they forget the most important thing was always understanding the child in front of them.  And that understanding matters far more than perfect terminology ever will.

Some gifted children do not look gifted in the way people expect. They are not always the child bringing home perfect marks and smiling politely in every school photo. Sometimes they are the child arguing with the teacher because the instructions felt illogical. Sometimes they are halfway through a novel under the desk because the lesson is moving painfully slowly. Sometimes they are deeply anxious, emotionally intense or completely exhausted from trying to exist in environments that do not fit them. Some are identified early. Others are missed for years because their giftedness sits alongside ADHD, autism, dyslexia, anxiety or emotional overwhelm. ( neuroparentinghub.co.za ) Giftedness is often far more complicated than people realise. It is not simply “being smart”. Many gifted children experience the world with unusual intensity, depth, curiosity and sensitivity. They may learn rapidly, think abstractly at a young age, ask complex questions or become deeply absorbed in particular interests. At the same time, many also struggle with perfectionism, emotional regulation, boredom, anxiety or feeling profoundly out of sync with the people around them. What giftedness can look like Gifted children do not all look the same. Some are highly verbal and endlessly curious. Some disappear into books or projects for hours. Some ask questions adults are not remotely prepared to answer. Others seem emotionally intense, highly sensitive or constantly frustrated by repetition and routine. A gifted child may: ask unusually deep or complex questions learn rapidly with minimal repetition become intensely focused on preferred interests struggle with boredom in repetitive environments show advanced vocabulary or reasoning become frustrated when ideas move slower than their thinking notice inconsistencies or unfairness quickly experience perfectionism or fear of failure struggle socially with age peers feel emotionally “out of sync” with other children become overwhelmed by sensory or emotional input argue passionately when something feels illogical appear mature in some ways and much younger in others Many gifted children have extremely uneven development. A child may discuss politics or philosophy far beyond their years and still completely fall apart because their sock feels wrong or their routine changed unexpectedly. That unevenness confuses adults constantly. Gifted does not mean easy One of the biggest misconceptions about gifted children is that they automatically thrive. Some do. Others spend years: under-stimulated misunderstood emotionally overwhelmed anxious disconnected from peers hiding their abilities socially frustrated by environments that never quite fit Some children become perfectionistic because things came easily early on and they never learned how to cope with struggle or mistakes. Others underperform intentionally because standing out socially feels unsafe. Some disengage completely after years of boredom and repetition. Giftedness does not protect children from difficulty. Sometimes it creates entirely different kinds of difficulty. Emotional intensity Many gifted children experience emotions intensely. A small injustice can feel enormous. A difficult world event may keep them awake at night. A tiny mistake can spiral into crushing self-criticism. Some children think deeply enough to worry about things adults do not expect children their age to even notice yet. Others become highly sensitive to: criticism conflict unfairness disappointment pressure failure emotional tension around them Adults sometimes mistake this intensity for dramatic behaviour or overreacting. Often, the child is genuinely experiencing emotions with unusual depth and intensity. School and gifted children School can become surprisingly complicated for gifted children. Some thrive academically but struggle socially. Some appear inattentive because they are mentally under-stimulated. Some become disruptive because their brain is searching constantly for complexity, novelty or stimulation. Others become quiet and disengaged after years of feeling disconnected from the learning environment. A gifted child may: finish work very quickly struggle with repetitive tasks become frustrated by slow pacing daydream when insufficiently challenged avoid work they see as meaningless become perfectionistic around mistakes underperform intentionally to fit in socially feel isolated from age peers struggle when learning focuses heavily on memorisation over thinking Sometimes the child described as “lazy” is actually deeply disengaged. Sometimes the child interrupting constantly is desperate for intellectual stimulation. Sometimes the child who appears anxious is carrying enormous internal pressure. Helpful support at school may include: enrichment opportunities intellectual challenge opportunities for deeper thinking flexible learning approaches emotional support understanding around perfectionism and anxiety environments that value curiosity and creativity support for uneven development Gifted children generally cope far better when adults understand that advanced intelligence does not remove emotional or developmental needs. ( neuroparentinghub.co.za ) Giftedness and neurodiversity Some gifted children are also neurodivergent. A child may be gifted and also have: ADHD autism dyslexia anxiety sensory processing difficulties executive functioning challenges This is sometimes called being “twice-exceptional” or “2E”. These children are often especially misunderstood because strengths can mask difficulties, while difficulties can mask strengths. A highly intelligent child may still struggle enormously with organisation, emotional regulation or everyday school demands. Both things are often true at the same time. At home At home, gifted children may: ask endless questions debate everything struggle to switch their brain “off” become emotionally intense react strongly to perceived unfairness hyperfocus on interests for hours become deeply frustrated by mistakes resist tasks that feel meaningless or repetitive need large amounts of downtime after school Some parents describe gifted children as emotionally exhausting and fascinating in equal measure. Many families find themselves parenting children who think deeply, feel deeply and notice far more than adults initially realise. Strengths and capacity Gifted children are individuals first. Many show strengths in: creativity problem-solving curiosity empathy humour rapid learning analytical thinking imagination deep focus around interests original thinking Some ask questions that completely change how adults see the world. At the same time, gifted children still need: emotional support understanding challenge boundaries regulation support connection space to fail safely Giftedness is not adulthood arriving early. They are still children. When to seek support If a child is consistently showing signs of advanced reasoning, intense curiosity, emotional intensity or a significant mismatch between ability and everyday functioning, it may help to speak to an appropriately qualified educational or psychological professional familiar with giftedness and neurodiversity. For many families, understanding giftedness finally explains experiences that previously felt confusing or contradictory. ( neuroparentinghub.co.za ) A final thought Gifted children are often described only through what they can do academically. But many are carrying inner worlds that are far bigger, more intense and more complicated than people realise. Sometimes the child asking endless questions is trying to understand a world that already feels overwhelming. Sometimes the child arguing constantly is searching desperately for logic and fairness. Sometimes the child who appears “too sensitive” is simply noticing and feeling far more than the people around them expected. Gifted children do not need to be turned into tiny adults or walking report cards.  They need understanding too.

Some children seem to hear everything and miss half of what was said at the same time. You call their name three times before they respond. Instructions seem to disappear halfway through. They look confused in noisy places. They constantly ask people to repeat themselves. Yet five minutes later they can hear a packet opening quietly from the other side of the house. Auditory Processing Disorder, often called APD or CAPD, is not the same as hearing loss. Children with APD usually hear sounds normally, but their brain has difficulty processing and interpreting what they are hearing, especially spoken language. In everyday life, this can make listening feel exhausting, confusing and overwhelming, particularly in busy environments like classrooms, assemblies, restaurants or group conversations. Many children with APD are working much harder to listen than adults realise. What Auditory Processing Disorder can look like APD can present differently from child to child. Some children struggle most in noisy environments. Others have difficulty remembering spoken information, following multi-step instructions or distinguishing between similar sounds. A child with APD may: ask for repetition frequently seem not to listen misunderstand verbal instructions struggle to follow conversations in noisy places confuse similar-sounding words lose track of multi-step directions appear distracted or “somewhere else” become overwhelmed in busy classrooms need extra processing time struggle with spelling, reading or phonics miss details during verbal teaching seem tired after listening-heavy environments cope better with visual information than spoken information Sometimes adults assume the child is not concentrating. Often, the child is trying incredibly hard to make sense of language that feels as though it keeps arriving scrambled, incomplete or too quickly. Hearing versus processing One of the most confusing parts of APD is that the child may pass a standard hearing test. That is because the ears themselves are often working normally. The difficulty happens further along the chain, in how the brain recognises, filters, organises and interprets sounds, especially speech. This is why many parents hear things like: “But their hearing is fine.” At the same time, the child may still be struggling enormously to keep up with verbal information in real-world environments. Why noisy environments are so difficult For many children with APD, background noise is one of the biggest challenges. A classroom fan. Chairs scraping. Children whispering nearby. Somebody coughing in the corridor. An air conditioner humming overhead. Most people’s brains automatically filter out these sounds so they can focus on the teacher’s voice. For children with APD, everything can arrive at once. By the end of the school day, many are mentally exhausted from trying to listen all day long. What APD is often mistaken for Auditory Processing Disorder is frequently misunderstood because many of the behaviours overlap with other learning and attention difficulties. Children may be described as: inattentive forgetful lazy distracted oppositional immature daydreamy “not listening” Some children are initially assumed to have behavioural difficulties when the real issue is that they are missing large pieces of verbal information. Others may also have ADHD, dyslexia, autism, language difficulties or learning differences alongside APD. That overlap can make things even more confusing for families. The emotional side of APD Children with APD often spend large parts of the day trying to work out what is happening around them. That takes energy. A child may laugh along socially without fully understanding the conversation. They may copy peers because they missed the instruction. They may panic internally when information is delivered too quickly. Some children become anxious about classrooms, group discussions or verbal tasks because they are constantly trying to catch up. Others begin avoiding participation altogether because they are tired of getting things wrong. Over time, repeated misunderstandings can affect confidence, emotional regulation and self-esteem. School and Auditory Processing Disorder School environments can be particularly difficult for children with APD because so much learning depends on listening. Children may struggle with: verbal instructions note-taking while listening classroom discussions group work following fast-paced teaching spelling and phonics remembering spoken information processing information quickly enough to respond A child may fully understand a concept once it is explained visually or one-on-one, yet still appear lost during whole-class teaching. Helpful supports at school may include: reducing unnecessary background noise where possible seating closer to the teacher visual supports alongside verbal instructions breaking instructions into smaller steps checking understanding gently allowing extra processing time written reminders and schedules calm, clear communication reducing pressure around rapid verbal responses Children usually cope far better once adults realise how tiring listening already is for them. APD at home At home, APD can sometimes look like constant repetition. Parents may feel as though they are saying the same thing over and over: Please put your shoes on. Please feed the dog. Please brush your teeth. Please come back, I’m still talking to you. This can become frustrating for everybody. But often the child is not deliberately ignoring instructions. They may have missed part of the information, processed it slowly or become distracted before the message fully registered. Helpful approaches at home may include: gaining the child’s attention before speaking reducing competing background noise where possible giving shorter instructions using visual reminders and routines checking understanding calmly allowing processing time before expecting a response breaking tasks into smaller steps Sometimes the child who seemed constantly frustrated suddenly looks calmer once communication stops feeling like a race. Strengths and capacity Children with APD are individuals first. Many are thoughtful, observant, creative and highly capable. Some become excellent visual learners or problem-solvers because they have spent years finding alternative ways to make sense of information. Some notice details other people miss completely. Others become incredibly good at reading visual patterns, routines or context because they cannot always rely comfortably on spoken information alone. At the same time, support needs remain real. A child can be bright, intelligent and articulate while still struggling enormously with listening fatigue, processing speed or noisy environments. Both things can be true at once. When to seek support If a child is consistently struggling to follow spoken information, cope in noisy environments or process verbal communication, it may help to speak to an audiologist or appropriately qualified professional familiar with auditory processing difficulties. Assessment is not about labelling a child negatively. For many families, understanding APD finally explains years of confusion, frustration and misunderstandings. A final thought Children with Auditory Processing Disorder are often working much harder to listen than the people around them realise. Sometimes the child who seems distracted is actually overloaded. Sometimes the child who keeps asking “What?” is trying desperately to piece the information together before the conversation moves on. Sometimes the child who appears to ignore instructions simply did not process them clearly enough in time. Understanding APD helps adults move away from: “Why aren’t they listening?” and towards:  “What might listening feel like for this child right now?”
