What Is a Spiky Profile? Why Capability and Support Needs Can Exist Together
By Robert Rackley MSc MIACP
Neurodivergent Psychotherapist | ADHD & Autism Specialist
A person can be highly capable in one area and need significant support in another.
Both can be true.
They may be articulate, knowledgeable and highly skilled in their profession, yet struggle to make a phone call.
They may understand complex ideas but become overwhelmed by seemingly ordinary decisions.
They may achieve excellent academic results while regularly forgetting to eat, respond to messages or complete essential daily tasks.
They may communicate confidently when discussing an area of interest but lose access to words when anxious, overloaded or placed under pressure.
These differences can appear contradictory to other people.
“If you can do that, surely you can do this.”
“You manage much more difficult things at work.”
“You’re clearly capable when you want to be.”
“You did it yesterday.”
But human ability is not evenly distributed.
For many ADHD and autistic people, the differences between areas of strength and areas requiring support can be particularly pronounced. This is sometimes described as having a spiky profile.
Understanding a spiky profile helps us move beyond simplistic ideas of whether somebody is capable or incapable.
A person can be both highly capable and significantly disabled.
Independent in some areas and dependent on support in others.
Confident in one environment and overwhelmed in another.
Successful and struggling.
Both can be true.
What is a spiky profile?
A spiky profile describes an uneven pattern of strengths, skills, difficulties and support needs.
If a person’s abilities were represented on a graph, the line would not remain at approximately the same level. It would contain high peaks in some areas and deep dips in others—creating a shape that looks spiky.
The person may have significant strengths in areas such as:
- Verbal reasoning
- Creativity
- Long-term memory
- Pattern recognition
- Problem-solving
- Visual thinking
- Specialist knowledge
- Analytical thinking
- Written communication
- Music or art
- Empathy
- Attention to detail
- Hyperfocus on meaningful work
At the same time, they may need considerable support with:
- Executive functioning
- Working memory
- Processing speed
- Emotional regulation
- Sensory processing
- Transitions
- Decision-making
- Planning and organisation
- Starting or stopping tasks
- Social communication
- Interoception
- Daily living activities
- Managing unexpected changes
The individual combination will be different for every person.
A spiky profile is not a diagnosis. It is a way of understanding that ability cannot always be represented accurately by one label, score or general judgement.
Research has identified unusually uneven cognitive profiles in autistic people, including significant differences between verbal and nonverbal abilities. However, a spiky profile is not limited to cognitive testing. It can also be visible across communication, learning, sensory processing, executive functioning, emotional regulation and everyday life.
The Autism Education Trust terminology guide describes a spiky profile as uneven functioning across cognitive abilities and skills, where an autistic person may excel in some areas while having increased support needs in others.
Not every autistic person likes or uses the term. As with all language concerning neurodivergence, individual preference matters. Some people prefer to describe their specific strengths and support needs rather than use the phrase “spiky profile.”
The underlying message remains important:
One area of ability cannot tell us how someone will function everywhere else.
Intelligence does not remove disability
People often assume that intelligence should transfer equally across every part of life.
If somebody can understand complex information, they are expected to organise themselves effectively.
If they can speak confidently, they are expected to communicate easily in every situation.
If they can work in a demanding profession, they are expected to manage domestic tasks without difficulty.
If they achieve academically, their difficulties may be dismissed as laziness, carelessness or a lack of effort.
But intelligence and executive functioning are not the same thing.
Knowing what needs to be done is different from being able to begin it.
Understanding time is different from accurately sensing its passage.
Having the language to explain an emotion is different from accessing those words while overwhelmed.
Being able to plan a complex project at work is different from planning dinner after a day of sensory and social demands.
A person’s areas of strength do not cancel their disability.
Sometimes those strengths actually make the disability less visible.
The person may develop complicated systems to compensate. They may work longer hours, prepare excessively, rely on anxiety, mask their confusion or use all their available energy to meet visible expectations.
Because the finished result looks competent, other people may never see what it cost.
As I discuss in Many ADHD and Autistic Adults Have Become So Good at Coping That They Don’t Realise They’re Struggling, visible achievement does not necessarily mean that someone is functioning sustainably.
“If you can do that, why can’t you do this?”
This question can create significant shame.
A person may already feel confused about why they can complete one complicated task but become stuck on something that appears much simpler.
They may think:
“Why can I do my job but not keep my home organised?”
“Why can I speak to a room full of people but avoid making one phone call?”
“Why can I help everybody else make decisions but become paralysed by my own?”
“Why can I remember detailed information from years ago but forget what I was asked to do five minutes ago?”
“Why can I write clearly but struggle to speak when I’m put on the spot?”
When other people question these differences, the individual may begin to view themselves as inconsistent, unreliable or fraudulent.
But complexity is not the only factor determining whether a task is accessible.
A task may be affected by:
- Interest
- Urgency
- Novelty
- Clarity
- Predictability
- Sensory demands
- Emotional significance
- Working-memory load
- Social expectations
- Fear of criticism
- The number of decisions involved
- The person’s current energy and regulation
- Whether the task has a clear starting point
- Whether somebody else is providing structure
A professionally complex task may be familiar, structured and interesting.
An apparently simple domestic task may involve initiation, prioritisation, sequencing, sensory discomfort and multiple decisions.
The simpler-looking task can therefore require more inaccessible skills.
Executive functioning can create deep dips in the profile
Executive functioning helps us organise behaviour towards a goal.
It includes abilities such as:
- Starting tasks
- Shifting attention
- Remembering instructions
- Prioritising
- Estimating time
- Organising materials
- Regulating impulses
- Monitoring progress
- Moving between activities
- Completing the final steps
An ADHD or autistic person may understand a task completely but remain unable to initiate it.
They may know that a bill needs to be paid.
They may have the money available.
They may understand the consequences of missing the deadline.
They may genuinely intend to do it.
Yet they remain stuck.
From the outside, this can look like a choice.
From the inside, it may feel like being unable to access the starting mechanism.
The person’s knowledge is intact. The difficulty lies in translating intention into action.
This gap can be especially difficult for other people to understand when the person performs extremely well in another area.
Success becomes evidence used against them:
“You can’t say you forgot. You remember everything about your special interest.”
“You can concentrate for hours when it suits you.”
“You manage deadlines at work.”
But memory, attention and motivation do not operate as single, consistent abilities.
A person may have an excellent long-term memory for meaningful information while struggling with working memory for everyday instructions.
They may hyperfocus on an engaging task while finding it extremely difficult to direct attention towards something repetitive or unclear.
This is not proof that the difficulty is deliberate.
It is part of the uneven profile.
Verbal ability can hide communication needs
A person may have a large vocabulary and still experience significant communication difficulties.
They may speak fluently about familiar subjects but struggle to:
- Process rapid verbal information
- Identify what they are feeling
- Understand indirect requests
- Respond to an unexpected question
- Recognise when it is their turn to speak
- Explain what support they need
- Follow multi-step spoken instructions
- Communicate during conflict
- Find words while emotionally overwhelmed
- Understand what another person expects without clear information
Strong expressive language can lead people to overestimate receptive processing, emotional awareness or the ability to advocate for oneself.
A person may sound as though they understand because they can repeat information or respond articulately.
They may only realise later that they did not fully process what was said.
Some people need written information even though they communicate very effectively through speech. Others may express themselves much more clearly in writing than in real-time conversation.
During sensory overload, shutdown, conflict or anxiety, access to language can change considerably.
The fact that someone communicated fluently earlier does not mean they are choosing not to communicate now.
Capacity can change with context.
Academic achievement can conceal everyday difficulties
A student may produce exceptional work while struggling to attend consistently.
They may have an advanced understanding of a subject but be unable to organise assignments.
They may contribute insightful ideas in discussion but find it extremely difficult to convert those ideas into written work.
They may complete the most intellectually demanding part of an assignment and then miss the submission because they could not manage formatting, uploading or the final administrative steps.
They may perform exceptionally in subjects connected to their interests while struggling significantly elsewhere.
Because the student is clearly intelligent, educators may assume that organisation, attendance or incomplete work reflects attitude.
Comments may include:
“They have so much potential.”
“They need to apply themselves.”
“They can do it when they want to.”
“They are capable of much more.”
These statements often confuse ability with access.
Potential cannot be reached simply through additional pressure. If the barrier involves executive functioning, sensory processing, unclear expectations or burnout, repeatedly telling the student they are capable may increase shame without providing the support they need.
A spiky profile means the student’s strengths should be developed while barriers are supported.
It should not require choosing between recognising capability and recognising disability.
Professional success does not mean support is unnecessary
Many neurodivergent adults hold responsible, highly skilled positions.
They may be therapists, healthcare professionals, teachers, academics, managers, artists, engineers, business owners or specialists in their field.
Their professional ability may cause others to underestimate their difficulties.
The person may be capable of delivering a presentation but need help booking the travel.
They may manage a team but struggle to manage their inbox.
They may solve difficult problems for clients while becoming overwhelmed by paperwork.
They may produce outstanding work but be unable to function in a noisy open-plan office.
They may be highly productive during periods of hyperfocus and then experience a severe reduction in capacity.
They may appear confident during a meeting and need hours to recover afterwards.
Professional achievement does not prove that accommodations are unnecessary.
In fact, accommodations may be part of what allows the person to perform at that level.
Helpful workplace supports might include:
- Clear written instructions
- Predictable expectations
- Flexible working arrangements
- Reduced sensory demands
- Advance notice of changes
- Time to process feedback
- Support with prioritisation
- Fewer unnecessary meetings
- Written follow-up after discussions
- Access to a quiet workspace
- Breaking large projects into clear stages
- Direct rather than implied communication
These adjustments do not reduce the person’s expertise.
They make it easier to access it.
As I explore in Wrong Environment, Right Person: Why Neurodivergent Strengths Are Often Missed, the environment can significantly influence which parts of a person’s profile become visible.
Daily living skills are not a measure of intelligence
One of the most painful parts of a spiky profile can be struggling with tasks that society considers basic.
A person may need support with:
- Cooking
- Cleaning
- Shopping
- Managing appointments
- Taking medication consistently
- Personal care
- Paying bills
- Responding to correspondence
- Travelling somewhere unfamiliar
- Maintaining routines
- Recognising hunger, thirst or fatigue
- Making everyday decisions
These difficulties are often treated as evidence that the person is immature or irresponsible.
The person may also judge themselves harshly:
“I should be able to do this.”
“Other adults don’t need help with this.”
“I’m intelligent, so why is this so difficult?”
But daily living tasks rely on many different systems working together.
Preparing a meal, for example, can require:
- Noticing hunger.
- Deciding what to eat.
- Checking which ingredients are available.
- Beginning the task.
- Managing smells and textures.
- Sequencing several steps.
- Monitoring time.
- Switching attention between items.
- Cleaning afterwards.
What appears to be one simple activity is actually a series of executive, sensory, cognitive and interoceptive demands.
Needing support with those demands does not contradict intelligence.
It reflects a different part of the person’s profile.
Support needs may change from day to day
A spiky profile is not necessarily fixed.
A person’s access to their abilities can change according to:
- Sleep
- Stress
- Illness
- Hormonal changes
- Sensory load
- Emotional demands
- Uncertainty
- Social pressure
- Burnout
- The familiarity of the environment
- The amount of recovery time available
- How many demands have already occurred
Someone may complete a task independently one day and need support with the same task another day.
This can lead to suspicion:
“You did it yesterday.”
“You were fine earlier.”
“Why are you suddenly unable to cope?”
But doing something once does not prove that it will always be accessible.
Capacity is not a moral quality. It changes.
The person may have completed the task previously by using an unsustainable amount of energy. They may now be experiencing the delayed cost.
They may also have encountered additional sensory, emotional or executive demands that are not visible to anyone else.
Variable capacity is not the same as manipulation.
Support should respond to the person’s current needs, not only to their best-ever performance.
The problem with functioning labels
Terms such as “high functioning” and “low functioning” attempt to summarise a complex person with one broad label.
A spiky profile shows why this can be misleading.
Someone described as high functioning may have their support needs overlooked because they speak fluently, work or live independently.
Someone described as low functioning may have their intelligence, understanding and potential underestimated because they communicate or complete daily activities differently.
A single label cannot capture:
- How much effort functioning requires
- Which environments are accessible
- What support is already in place
- Whether the person is masking
- How capacity changes under stress
- Which abilities are hidden by communication differences
- What happens when support is removed
- How long the person needs to recover
Rather than asking whether somebody is generally high or low functioning, it is more useful to ask:
- What can this person do independently?
- What can they do with support?
- What becomes difficult under pressure?
- What communication method is most accessible?
- Which sensory experiences reduce capacity?
- What conditions help their strengths become available?
- What support makes participation sustainable?
This gives us meaningful information.
A functioning label usually does not.
Strengths should not be used to deny support
A strengths-based approach is important.
Neurodivergent people are too often described only through deficits, difficulties and things they cannot do.
Recognising creativity, expertise, persistence, pattern recognition, honesty, innovation and deep knowledge can help challenge that narrative.
But strengths-based practice should not become strengths-only practice.
Celebrating a person’s abilities while ignoring their disability is not affirming.
Statements such as “ADHD is your superpower” may feel invalidating when someone is struggling to manage daily life.
Similarly, highlighting an autistic person’s specialist knowledge does not address sensory overload, communication barriers or the energy required to function.
Strengths and support needs can coexist.
The person should not have to perform incompetence to receive help.
They should not need to hide their strengths so that their difficulties will be believed.
Nor should they have to hide their difficulties to be recognised as capable.
Support does not erase independence
Independence is often understood as doing everything without assistance.
But this is an unrealistic standard.
All people rely on systems, relationships, technology and shared knowledge.
A more useful goal is sustainable autonomy: having meaningful choice, appropriate support and as much control as possible over one’s life.
Support may include:
- Visual plans
- Reminders
- Body doubling
- Written communication
- Help breaking down decisions
- Sensory adaptations
- Predictable routines
- Assistance with paperwork
- Co-regulation
- Recovery time
- Flexible expectations
- Support with transitions
These supports do not make the person less capable.
They may allow the person to use abilities that would otherwise remain inaccessible.
Glasses do not invalidate somebody’s ability to read.
A calendar does not invalidate somebody’s professional competence.
Written instructions do not invalidate intelligence.
Sensory supports do not invalidate participation.
Support is not the opposite of capability.
Often, support is what makes capability accessible.
Understanding the profile reduces shame
Before understanding their neurodivergence, many people explain their uneven abilities through personal failure.
They believe they are lazy.
Inconsistent.
Too sensitive.
Undisciplined.
Difficult.
Not trying hard enough.
They may have spent years being praised for their strengths and criticised for their difficulties without anyone recognising that both were part of the same profile.
Identifying the pattern can bring relief.
The person begins to understand:
“I am not pretending to struggle.”
“My difficulties are not disproved by my achievements.”
“Needing help does not make me incapable.”
“My abilities are real, and so are my support needs.”
This understanding does not remove every difficulty.
But it can replace shame with curiosity.
Instead of asking, “What is wrong with me?” the person can begin asking:
“What part of this task is inaccessible?”
“Which ability is being demanded here?”
“What conditions helped me do this before?”
“Am I overloaded?”
“Would written information help?”
“Do I need support with starting rather than understanding?”
“What can be changed in the environment?”
These questions lead towards practical support rather than self-blame.
Look at the whole person
A person is not only their highest achievement.
They are not only their most difficult day.
They are not only their intelligence, diagnosis, job, communication style or support needs.
Understanding a spiky profile requires holding several truths at the same time.
The person can be knowledgeable and need guidance.
Articulate and unable to speak under pressure.
Independent and need co-regulation.
Creative and struggle with initiation.
Empathetic and misread social situations.
Professionally successful and unable to manage domestic tasks consistently.
Confident and overwhelmed.
Capable and disabled.
When we accept that both can be true, we stop treating human ability as a simple scale.
We become less likely to underestimate someone because of their difficulties.
We also become less likely to deny support because of their strengths.
A person can be highly capable in one area and need significant support in another.
Their support needs do not erase their strengths.
Their strengths do not erase their support needs.
Both deserve to be recognised.
Therapy, Training and Speaking
I provide neurodivergence-affirming therapy for ADHD and autistic adults experiencing executive functioning difficulties, sensory overwhelm, masking, burnout, emotional regulation difficulties and shame connected to inconsistent capacity.
My approach combines clinical experience, specialist training and my own lived experience as a neurodivergent psychotherapist. Therapy can help individuals understand their personal profile, identify accessible supports and separate genuine areas of difficulty from years of negative messages about laziness, effort or capability.
Sessions are available in person in Limerick and online internationally.
I also provide neurodiversity training, workplace talks and professional CPD for healthcare professionals, therapists, educational settings, workplaces and organisations.
Training can explore spiky profiles, executive functioning, sensory processing, communication, masking, emotional regulation and why visible competence should never be used to dismiss a person’s support needs.
Organisations seeking a tailored programme can learn more about my group and organisational neurodiversity training.
