The three formally recognized learning disabilities are dyslexia, which affects reading, dysgraphia, which affects writing, and dyscalculia, which affects mathematics. In the DSM-5 these are not three separate diagnoses but one — specific learning disorder — with specifiers for impairment in reading, in written expression, and in mathematics. Several other conditions appear on lists like this one without belonging to the same category: ADHD is a disorder of attention rather than learning, developmental language disorder is a language disorder, and intellectual disability is explicitly excluded from the legal definition. Knowing which is which changes what you ask for and who assesses it.
Learning disability, learning difference, learning disorder
Three terms, used interchangeably, that do not mean quite the same thing. Knowing which framework someone is working from explains a great deal of the confusion families run into.
In the DSM-5, the diagnosis is specific learning disorder, with three specifiers: impairment in reading, in written expression, and in mathematics. Dyslexia, dysgraphia, and dyscalculia are the everyday names for those three patterns rather than three separate diagnoses.
In US education law it is a legal category. Under IDEA, "specific learning disability" is one of the categories that determines eligibility for services, and the statute defines it as "a disorder in 1 or more of the basic psychological processes involved in understanding or in using language, spoken or written, which disorder may manifest itself in the imperfect ability to listen, think, speak, read, write, spell, or do mathematical calculations."
That legal definition is explicit about its edges, and this is the useful part: it includes "perceptual disabilities, brain injury, minimal brain dysfunction, dyslexia, and developmental aphasia", and it does not include "a learning problem that is primarily the result of visual, hearing, or motor disabilities, of intellectual disabilities, of emotional disturbance, or of environmental, cultural, or economic disadvantage."
"Learning differences" is increasingly preferred by many families and educators, because it describes a difference in how a person learns rather than a deficiency in the person.
The three learning disorders
These are the ones the term properly refers to.1
Dyslexia
Affects reading. Difficulty with accurate or fluent word reading, decoding, and spelling, despite adequate teaching. It is not about reversing letters and it is not a problem of intelligence or effort. Structured literacy instruction is the intervention with the strongest evidence behind it.
Dysgraphia
Affects written expression. Difficulty with the physical act of writing, with spelling, or with getting organized thought onto a page — often all three. A child may talk fluently about a subject and produce three labored sentences about it. Handwriting and written expression are separable, and it matters which one is affected.
Dyscalculia
Affects mathematics. Difficulty with number sense, learning arithmetic facts, and calculating accurately or fluently. It is far less recognized than dyslexia and frequently goes unidentified for years, often mistaken for math anxiety rather than being its cause.
Frequently listed, but a different category
Being explicit about this is the most useful thing this page can do. Most lists of this kind bundle everything together, which leaves families with the wrong search terms, the wrong expectations of assessment, and sometimes the wrong professional.
ADHD
Not a learning disability. ADHD affects attention, impulse control, and executive function.2 It very often affects learning, and it is diagnosed separately under its own criteria. A child can have both, and roughly speaking co-occurrence is common enough that assessment for one should consider the other.
Developmental language disorder
A language disorder rather than a learning disability: persistent difficulty understanding or using language, without another condition accounting for it. It is heavily under-identified, and because it can be quiet rather than disruptive it is easy to miss in a classroom.
Language processing disorder
Difficulty attaching meaning to language that is heard, as distinct from hearing it. Often described as a subtype of auditory processing difficulty, and assessed by a speech-language pathologist.
Auditory processing disorder
Difficulty making sense of sound despite normal hearing. It is assessed by an audiologist, not a psychologist, which is a practical difference worth knowing before you request an evaluation. The diagnosis itself is contested among clinicians.
Visual processing difficulty
Difficulty interpreting visual information despite adequate eyesight — spacing, copying from a board, tracking a line of text. Like auditory processing, it is about interpretation rather than the sense organ.
Nonverbal learning disorder
Not in the DSM-5 or the ICD-11. The label describes a pattern — strong verbal ability alongside difficulty with visual-spatial reasoning, motor coordination, and social inference — but it is not a formal diagnosis, and what it captures is often better described by naming its parts.
Executive function difficulty
A description rather than a diagnosis. Planning, starting, sequencing, holding information in mind, and switching between tasks. It cuts across ADHD, learning disorders, and autism, and accommodations for it are frequently more useful than a label for it.
Dyspraxia and developmental coordination disorder
A motor condition, not a learning one — but it affects handwriting, PE, and the practical side of school enough that it appears on most lists like this. Note that IDEA's definition of specific learning disability explicitly excludes learning problems that are primarily the result of motor disabilities.
Delayed speech
Speech developing later than expected. It is a speech and language matter rather than a learning disability, though early language difficulty and later reading difficulty are related often enough that it is worth watching.
Intellectual disability
A distinct diagnosis involving both intellectual functioning and adaptive behavior. IDEA's definition of specific learning disability explicitly excludes it, which is why the two are not interchangeable and why assessment routes differ.
Twice-exceptional
High ability alongside a learning difference. The two can mask each other: the ability compensates for the difficulty, the difficulty drags the ability back to average, and the child is identified for neither.
It is a common reason a plainly bright child struggles in a way nobody can account for, and it is worth raising directly if that describes your child.
How these are identified
Through a psychoeducational evaluation — cognitive and academic testing alongside developmental and school history. There is no single test.
A school evaluation is free and determines eligibility for an IEP or a 504 plan. Request it in writing — that starts a legal timeline that a conversation does not.
A private assessment is usually faster and more detailed, and it does not by itself oblige a school to do anything. Many families end up doing both.
What actually helps a child with a learning disability
Three things, and the order matters. The first is the intervention, the second removes what is in its way, and the third is the one families most often reach too late.
- Structured, explicit instruction aimed at the specific difficulty
For reading, that means structured literacy. General tutoring, and more of the same instruction that has already not worked, are the two most common substitutes — and neither is the thing. Ask what the program is called and what it targets; a specific answer is a good sign.
- Accommodations that remove the barrier, not the task
Extra time, text-to-speech, a scribe or typing, a calculator where the point of the lesson is not arithmetic. The test is whether the accommodation lets a child show what they know, rather than lowering what is asked of them. Those are different things and get confused constantly.
- Attention to the emotional side, early
Children who struggle for years without an explanation frequently conclude that they are stupid. That conclusion outlasts the academic gap and is harder to undo than the reading itself. Naming the difficulty to the child, in terms they can use, is part of the intervention rather than an afterthought.
An IEP or 504 plan is how the first two get written down and held to. Our questions-to-ask guide and school evaluation request letter are built for those meetings, and resources for teachers can be handed over directly.
When to seek an assessment
You do not need to know which learning disability it might be in order to ask for an evaluation. Identifying it is the evaluation's job.
Frequently Asked Questions
Is dyslexia in the DSM-5?
The DSM-5 diagnosis is specific learning disorder, with impairment in reading as one of its three specifiers. Dyslexia is the everyday name for that pattern rather than a separate diagnosis. IDEA, the US education law, does name dyslexia directly in its definition of specific learning disability.
Is ADHD a learning disability?
No. ADHD affects attention, impulse control, and executive function, and it is diagnosed under its own criteria. It very often affects learning and frequently co-occurs with a learning disorder, but it is a different category and is assessed differently.
How is a learning disability diagnosed?
Through a psychoeducational evaluation — cognitive and academic testing alongside developmental and school history. You can request one from your school district in writing, which starts a legal timeline, or arrange a private assessment. The two are not interchangeable and qualify a child for different things.
Can a gifted child have a learning disability?
Yes, and it is called twice-exceptional. High ability and a learning difference can mask each other, so the child performs around average and is identified for neither. It is one of the more common reasons a bright child struggles without anyone being able to say why.
What helps a child with a learning disability?
Structured, explicit instruction targeted at the specific difficulty, accommodations that remove the barrier rather than the task, and attention to the emotional side. Children who struggle for years without an explanation frequently conclude they are stupid, and that belief outlasts the academic gap.
Is nonverbal learning disorder a real diagnosis?
It is not in the DSM-5 or the ICD-11. The pattern it describes is real and recognizable, but because it is not a formal diagnosis it is often better addressed by naming the specific difficulties involved.
What are the different types of learning disabilities?
Three are formally recognized: dyslexia, which affects reading; dysgraphia, which affects writing; and dyscalculia, which affects mathematics. In the DSM-5 they are specifiers of a single diagnosis, specific learning disorder, rather than three separate ones.
What is the difference between a learning disability and a learning difference?
They describe the same thing from different angles. "Learning disability" is the clinical and legal term; "learning difference" is increasingly preferred by families and educators because it describes how a person learns rather than implying a deficiency. Neither changes what support a child needs.
