ADHD, autism, learning differences and IQ: what each tells you

Attention, intelligence and diagnosis answer different questions

Psychological assessment can combine interviews, observations and different kinds of tests. The question being investigated determines which information matters. A reasoning task is not a substitute for a developmental history, just as a spelling exercise cannot explain everything about someone’s learning.

Consider a fictional learner who explains a science concept clearly but struggles to produce a written answer. The observation is specific: understanding and written output differ on that task. It does not tell us whether the difficulty involves reading, handwriting, attention, language, time pressure or something else. Asking “Which part is getting in the way?” opens more useful possibilities than deciding the learner is clever or not clever.

Our guides to cognitive domains and working memory explain why these abilities should be discussed separately. They provide vocabulary for asking better questions, rather than a way to assign yourself a diagnosis.

ADHD and ADD: attention difficulties in context

ADHD involves persistent inattention and/or hyperactivity and impulsivity that interfere with functioning across settings. Adults can have ADHD, and assessment considers symptoms originating in childhood. Being distracted occasionally is not enough to establish it.

ADD, short for attention deficit disorder, still appears in some information and data sources. Current guidance uses ADHD, including an inattentive presentation. The absence of obvious physical restlessness does not, by itself, settle whether ADHD is present.

The CDC stresses that no single test diagnoses ADHD. Sleep difficulties, anxiety and other conditions can resemble it. A useful account might say: “I repeatedly lose track of multistep tasks at home and work, and this has a long history.” That is information to explore with a professional, not proof of a diagnosis.

ADHD symptoms: what changes with age and context?

Inattention can show up as repeatedly missing details, losing necessary belongings or leaving tasks unfinished. Hyperactivity can involve frequent movement or difficulty remaining seated; impulsivity can involve interrupting or struggling to wait. A person may mainly have attention difficulties, mainly hyperactive and impulsive symptoms, or both. These are examples to discuss, not a checklist for diagnosing yourself.

In children, difficulties may become visible during lessons, play or everyday routines. In adults, the picture can include internal restlessness, disorganisation and difficulty managing deadlines or appointments. Less visible movement does not necessarily mean fewer difficulties. Describe what happens now and how the pattern has changed, instead of expecting an adult to behave like a very active child.

Context matters: forgetting something during an unusually demanding week is different from a longstanding pattern that disrupts several areas of life. ADHD assessment considers frequency, persistence, developmental expectations and practical impact. Symptoms also overlap with other difficulties, and conditions can coexist. A useful question is “What else could explain this pattern, or be contributing alongside it?”

Looking for an ADHD test? First identify what it measures

An ADHD symptom questionnaire asks about experiences or behaviour. A validated screening questionnaire can help identify concerns for further assessment; its score is not a diagnosis. Before using one, check the intended age group, language and purpose, who developed it and how the result should be interpreted. A questionnaire designed for adults should not automatically be used to assess a child.

Clinical evaluation combines information rather than relying on one score. NICE guidance specifies a clinical and psychosocial assessment, developmental and psychiatric history, and information from observers. Rating scales can contribute, but NICE advises against diagnosing solely from them. For children, CDC guidance also describes checking for other explanations and gathering accounts from adults who know the child in different settings.

An IQ test asks a different question about cognitive performance. Neither a strong result nor a disappointing one tells you whether ADHD is present. Remote appointments may form part of a clinical service; an online questionnaire alone is not equivalent to that service. Ask who interprets the findings and what happens after the assessment, rather than judging it only by its format.

What to bring to a conversation about possible ADHD

Take a few examples from different parts of life, alongside any relevant records you already have. For an adult, school reports or a relative’s recollection may help explore childhood history; for a child, a teacher’s account can add another setting. If records or a suitable informant are unavailable, say so and ask how the clinician will handle that gap.

For example: “On three recent workdays I started replying before finishing the instructions and had to redo the task. At home, I abandoned two routine jobs halfway through.” This is an invented illustration of useful detail, not evidence that those behaviours mean ADHD. Add what the interruption cost you and whether someone else noticed it.

Ask what information would help distinguish ADHD from other explanations, whether additional learning needs should be assessed, and what support can be discussed while you wait. Include the difficulties that matter most to you, even if they do not match a familiar description. The appointment should clarify your needs, not simply attach a label to a questionnaire result.

Autism, Asperger’s and the range of abilities

Autism involves differences in development affecting communication, interaction and patterns of behaviour or interests. The spectrum includes varied strengths, challenges and support needs. An autism assessment considers a wider developmental picture than a single online questionnaire.

Autistic people have different intellectual abilities. Some have an intellectual disability; others have average or above-average intelligence. A high score therefore should not be used to dismiss difficulties, and a difficulty communicating should not be treated as a measure of what someone understands.

Asperger’s disorder was a separate label in earlier diagnostic manuals. DSM-5 incorporated established diagnoses under autism spectrum disorder. You may still encounter the older wording in records or personal descriptions. Ask which terminology the person prefers and which assessment framework a document uses.

Sources: NIMH: autism spectrum disorder · NHS: what is autism · CDC: autism diagnosis

An Asperger diagnosis in an old report: what matters now?

A change in diagnostic terminology does not erase a person’s history. The DSM-5 guidance reproduced by the CDC places an established DSM-IV Asperger diagnosis within autism spectrum disorder. If an older report uses Asperger’s, keep the report and ask how its findings relate to the current assessment framework. The useful question is what it explains about the person and what needs updating.

Personal language and clinical terminology have different purposes. Some people retain Asperger’s as part of their identity; others prefer autistic person or another description. The National Autistic Society explains this variation. Follow the person’s preference when speaking about them, without assuming that their chosen term tells you how much help they need or that everyone sharing it has the same abilities.

NICE highlights that measured intellectual ability and everyday functioning can differ. A fictional adult might explain a complex work task clearly but struggle to participate in a noisy meeting or organise a change in routine. The first observation does not cancel the second. Describe both the strength and the barrier, rather than assigning a broad label such as high-functioning and leaving the practical difficulty unexplained.

A quieter workspace or an agreed way to communicate may be useful topics to discuss. Ask what the person finds helpful and review whether it actually improves access to the task. NHS guidance notes that support needs can change across situations and over time. An adjustment should address a stated need, not follow automatically from an old label or a test score.

Adult autism assessment: beyond a familiar label or questionnaire

Autism may be recognised in adulthood even though it is developmental. The NHS explains that some adults have learned to adapt or mask differences, so they are less noticeable; doing so can be tiring. A brief, comfortable conversation does not describe every setting. Explain the effort involved as well as what another person can see, without treating masking or tiredness alone as proof of autism.

An adult evaluation looks at communication, social interaction, sensory experiences, routines and interests alongside early development and present-day life. NIMH notes that some features overlap with anxiety or ADHD, so interpretation needs care. The purpose is to understand a pattern and possible explanations, not to count isolated traits or decide whether somebody resembles a stereotype.

Ask the service how it gathers developmental information and whether a previous report would help. If childhood records or someone who knew you then are unavailable, explain that and ask what other information the team can consider. The NHS describes adult assessment as potentially involving questionnaires, conversations, documents and people who know the person; a web questionnaire on its own does not provide that process.

Ask how the outcome will translate into practical support. A useful discussion includes strengths, current difficulties, any other conditions identified and who can help next. Referral routes and available services differ by location. A local health professional can explain the assessment route and support available during a wait; you do not need to settle on an identity label before describing a difficulty.

Dyslexia: reading difficulty is not an intelligence verdict

Dyslexia commonly affects reading, writing and spelling; it does not mean low intelligence. Assessment examines learning difficulties in detail and can help identify appropriate support. Local assessment pathways differ, so ask a school, educational service or qualified assessor which route applies.

For a fictional student, “reads a paragraph slowly but explains the topic well when it is read aloud” is a more informative observation than “is bad at school”. It identifies two task conditions to discuss. The aim is to understand access to the material, without using one successful or unsuccessful exercise to confirm a diagnosis.

Dyspraxia and developmental coordination disorder

Developmental coordination disorder (DCD), often called dyspraxia, affects physical coordination and everyday tasks. It can make written work or other activities harder without defining intelligence. The word dyspraxia can also be used in other contexts, so the precise meaning matters.

For example, a fictional person may know what they want to write but find the physical production of handwriting demanding. “Knows the answer” and “can produce it in this format, at this speed” are different observations. Explain the practical difficulty to an appropriate professional rather than assuming it reflects effort or ability.

Sight words and Makaton: tools with different purposes

In reading, sight words are words a reader recognises automatically. Recognising familiar words is one part of reading, alongside understanding language and working out unfamiliar words. NICHD highlights explicit, systematic instruction across phonemic awareness, phonics, fluency, vocabulary and comprehension; a word list alone does not represent the whole learning task.

Makaton is a communication programme using signs, symbols and speech. It is not an IQ test or a diagnosis. Whether it fits someone’s communication needs is a separate question from which clinical label they have.

Before choosing a resource, name the goal: recognising printed words, understanding instructions, expressing a choice or producing written work. A resource designed for one goal may not answer another. Ask the learner what is difficult and involve the relevant educational or communication professional when support is needed.

Sight words: build recognition alongside phonics and meaning

Recognising a word instantly is a reading outcome, not an instruction to memorise its outline as a picture. Phonics teaches the relationships between written letters and speech sounds. The IES foundational reading guide recommends applying these relationships to regular words, explicitly teaching irregular words and practising recognition. Familiar-word practice belongs alongside a way to work out unfamiliar words.

For practice at home, ask the teacher which words and spelling patterns the learner has already been taught. Choose a small selection from their current reading rather than an unrelated long list. Read each word accurately, attend to its letters and pronunciation, and revisit it in a sentence. Where English spelling is irregular, ask how that part is being explained at school so the support is consistent.

A useful observation is whether a learner recognises a practised word in a new sentence and understands the sentence. Recognising the same flashcard repeatedly answers a narrower question. The IES guide includes daily connected-text reading with feedback; the National Reading Panel also reviewed guided oral reading. Practice should make room for both accurate word reading and a conversation about meaning.

If progress remains difficult, bring examples of what happens when the learner sounds out words, reads familiar words and explains a passage. Ask what targeted teaching or assessment would help. The cited IES guide concerns early reading in English: an English word list should not be treated as a ready-made programme for another language. Agree suitable materials with the educator.

Makaton: choosing support for everyday communication

Makaton can support understanding as well as expression. For example, the purpose might be to make a choice or share information, rather than to practise reading printed words. The Makaton Charity explains that signs accompany speech in spoken-word order; symbols can also support someone who cannot or prefers not to sign. A person’s communication preferences matter when choosing how to use it.

Makaton and British Sign Language are different. BSL is a language with its own grammar, whereas Makaton supports spoken communication. Do not assume a Makaton course teaches BSL or provides the communication access a particular Deaf person needs. For Makaton outside the UK, check the local programme: the charity explains that signs are selected from the sign language used in that country.

The charity’s Level 1 training introduces everyday use and the first stages of its Core Vocabulary. Learning with a Makaton Tutor allows practice and feedback. Before starting, discuss one useful situation with the person and those who support their communication, then ask which authorised resources and training fit it. Coordinate with a speech and language professional if individual advice is needed. A written overview cannot demonstrate accurate signs or select a communication programme for someone.

Memory difficulties and amnesia need their own context

Occasional forgetting does not, by itself, establish amnesia or a developmental condition. Persistent memory problems that affect daily life merit medical assessment. Sleep problems, stress and other causes may be relevant; do not infer the cause from a quiz score.

Write down what happened rather than assigning a broad label: forgetting an appointment, losing the thread of instructions and being unable to recall an event are different descriptions. If confusion appears suddenly, seek urgent medical help rather than waiting to repeat an online test.

How to prepare a useful assessment question

Create a brief note with four headings: the task, the context, the history and the consequence. For instance: “Reading a work document; especially when instructions are dense; present for years; takes so long that I miss deadlines.” Include situations where the task goes better as well. This is a way to organise your account, not a scoring system.

Ask what the proposed assessment can answer, which information it uses and how findings will translate into practical support. Clarify language requirements, accessibility arrangements, costs and follow-up before booking. These questions also help distinguish an educational quiz from an assessment intended for clinical or educational decisions.

Mental health concerns may deserve attention alongside learning questions. If worry or low mood is part of the picture, our related PersonalityTester guide explains stress, anxiety and depression. The distinction matters: a difficulty concentrating should not automatically be explained by either a personality trait or a developmental diagnosis.
