Summary
Dyspraxia, formally known as Developmental Coordination Disorder (DCD), is a neurodevelopmental difference affecting motor planning, coordination, and proprioceptive integration. It is common (5–6% of children), frequently co-occurring with autism and ADHD, and profoundly under-researched relative to its prevalence and impact. It has been called the “forgotten” neurodevelopmental condition, and the label fits: funding, research attention, and clinical awareness lag far behind the other conditions it overlaps with.
The two names reflect different emphases. “DCD” is the clinical term used in DSM-5 and ICD-11, focusing on the motor coordination difficulty. “Dyspraxia” is the term more commonly used in the UK and by the community itself, emphasising the motor planning dimension: the difficulty is not just in executing movements but in organising, sequencing, and initiating them. This wiki uses both, following the convention that the person’s own language takes precedence.
What it looks like
The core difficulty is motor planning: the brain’s ability to conceive, organise, and execute unfamiliar movement sequences. This affects gross motor skills (running, catching, balance), fine motor skills (handwriting, using cutlery, tying shoelaces), and the planning of complex motor sequences (getting dressed in order, navigating a new route, learning to drive).
But DCD is not purely a motor condition. The sensory dimensions are substantial and underappreciated. Proprioceptive processing (knowing where your body is in space without looking) and vestibular processing (balance, spatial orientation) are frequently affected. Many people with DCD describe a persistent uncertainty about their own body: misjudging distances, bumping into door frames, not knowing how hard to grip something. See Proprioceptive processing for the overlap with autistic sensory experience.
Research has found that 31% of children with DCD show sensory modulation difficulties comparable to those seen in autism. The boundary between DCD’s proprioceptive-vestibular profile and autism’s broader sensory processing differences is blurry, which is part of why the overlap problem matters.
Executive function is also affected. Planning, organisation, time management, and working memory difficulties appear at rates exceeding what motor difficulty alone would predict. Whether these are intrinsic to DCD or reflect the cognitive overhead of compensating for motor planning difficulties (doing manually what other people’s brains automate) is unresolved.
Co-occurrence
The co-occurrence rates are striking. DCD appears in an estimated 60–90% of autistic people and roughly 50% of people with ADHD. Dyslexia co-occurs frequently. The degree of overlap raises the same question the overlap problem page addresses: are these genuinely separate conditions, or different expressions of shared underlying neurodevelopmental variation?
Despite these rates, DCD is routinely missed in autism and ADHD assessments. Clinicians assessing for autism may attribute motor difficulties to “clumsiness” without investigating further. The motor planning dimension of DCD is invisible in a standard clinical encounter where the person is sitting in a chair answering questions.
The forgotten condition
DCD has a fraction of the research funding, media attention, and public awareness of autism or ADHD. The Dyspraxia Foundation (UK) is the primary advocacy body, doing important work with minimal resources. There are no celebrity advocates, no bestselling memoirs, no TikTok awareness campaigns on the scale that autism and ADHD have attracted.
The consequences are practical. Teacher awareness is low: a child with DCD who can’t hold a pen properly is more likely to be told to “try harder” than to be assessed. Adult services are essentially non-existent in most areas. Occupational therapy, which is the primary evidence-based support, has long waiting lists and is often unavailable for adults.
Open questions
Is DCD a motor condition with sensory features, or a sensory-motor integration condition? The answer changes what support looks like: motor-focused interventions (task-oriented training) versus sensory integration approaches (addressing the proprioceptive and vestibular dimensions).
Why is DCD so underresearched given its prevalence? 5–6% is comparable to ADHD. The research funding disparity is enormous. Whether this reflects the condition’s relative invisibility, the lack of a pharmaceutical treatment (which drives ADHD research funding), or historical accident is unclear.
