What is Sensory-Based Feeding Selectivity and its ICD-11 features?
Sensory-Based Feeding Selectivity is persistent food restriction driven by aversive sensory responses to texture, taste, smell or appearance. ICD-11 captures it within ARFID (6B83); early-childhood features include narrowed intake, sensory-based avoidance, and consequences such as faltering growth, nutritional deficiency or supplement dependence, not explained by illness or weight concerns.
Read the answer AnswerWhat is Separation Anxiety Disorder?
Separation Anxiety Disorder (ICD-11 6B05) is excessive, developmentally inappropriate fear of being apart from a primary caregiver. Some clinginess is normal in early childhood; it becomes a clinical concern only when distress is intense, persistent over weeks, and disrupts sleep, school and family life. Diagnosis follows a clinician-administered review, not a checklist.
Read the answer AnswerSeparation Anxiety Disorder (ICD-11 6B05): a clinician explainer
Separation Anxiety Disorder (ICD-11 6B05) is marked, developmentally excessive fear or anxiety about separation from attachment figures, persisting over time and causing functional impairment. In early childhood it presents as excessive worry about harm to caregivers, refusal to separate, separation nightmares and somatic complaints — exceeding normative developmental responses.
Read the answer AnswerWhat is Situational in child development?
In child development, 'situational' means a young child's skills, behaviour and mood can change depending on the setting — who is present, where they are, and how familiar the routine feels. It is normal and expected: context shapes how abilities show up. Because of this, watching a toddler across several everyday situations gives a truer picture than a single snapshot. A difference seen only in one setting often points to the setting; one seen everywhere is worth a closer look.
Read the answer AnswerWhat is Social Communication Difficulties?
Social Communication Difficulties (ICD-11 6A01.22) describe persistent difficulty with the social use of language — turn-taking, staying on topic, reading tone, and understanding meaning that isn't said directly — despite adequate words and grammar. It sits within developmental speech or language disorders and is distinct from autism. Diagnosis requires a clinician-led assessment that looks for a consistent, participation-limiting pattern.
Read the answer AnswerWhat is Social Communication Difficulties, and its ICD-11 features?
Social Communication Difficulties (ICD-11 6A01.22) is a persistent impairment in the pragmatic, social use of language disproportionate to structural language and cognition, diagnosed only when autism's restricted/repetitive behaviours are absent. Early-childhood features span reciprocity, context adaptation, narrative inference and non-verbal integration.
Read the answer AnswerWhat is special education?
Special education is a planned, individualised approach to teaching children who learn differently — because of developmental, communication, learning, sensory or other differences. Rather than a one-size-fits-all lesson, it adapts what is taught, how it is taught, the pace, materials and support around each child so they can access learning and thrive. Built on a child's strengths and often delivered alongside therapists, it works best when it begins early and involves the family.
Read the answer AnswerWhat is Specific Learning Disability?
Specific Learning Disability (SLD) is a persistent, unexpected difficulty with reading, writing or maths in a child whose overall ability predicts far better performance. It reflects how the brain processes certain information, not low intelligence or effort. Classified under ICD-11 6A03/6A04, it is usually identified around ages 6–8 and responds well to targeted teaching.
Read the answer AnswerWhat is Specific Learning Disability, and what are its ICD-11 features in early childhood?
Specific Learning Disability — ICD-11 Developmental learning disorder (6A03) — is a persistent, school-age difficulty in reading, written expression or mathematics, substantially below age expectation and not due to intellectual disability, sensory loss or inadequate instruction. It is not diagnosed in early childhood; only precursor skills (phonological awareness, number sense) can be monitored, with formal assessment meaningful around 6–8 years.
Read the answer AnswerWhat is Stereotyped Movement Disorder?
Stereotyped Movement Disorder (ICD-11 6A06) describes repetitive, rhythmic, seemingly purposeless movements — such as hand-flapping, rocking, or head-nodding — that begin in early childhood and are not explained by another condition. It is clinically significant only when movements are persistent, disruptive, or cause self-injury. It may occur with or without self-injury and often co-occurs with autism or intellectual developmental conditions; sudden involuntary movements need medical review to exclude other causes.
Read the answer AnswerStereotyped Movement Disorder (ICD-11 6A06)
Stereotyped Movement Disorder (ICD-11 6A06) involves voluntary, repetitive, rhythmic, purposeless movements — rocking, flapping, head-banging — that begin early, persist, and impair function or cause self-injury. ICD-11 distinguishes presentations with and without self-injury; differentiate from tics, seizures and compulsions.
Read the answer AnswerWhat is Task Completion in child development?
Task completion is a child's growing ability to start an activity, stay focused, and see it through to the end. It draws on attention, memory, planning and self-control working together, and develops gradually between about 3 and 7 years. It is not a diagnosis but a cognitive skill that grows with playful, well-paced practice and gentle scaffolding.
Read the answer AnswerWhat is Task Initiation in child development?
Task initiation is a child's ability to begin a task independently, without long delay, repeated prompting or distress — such as starting to dress, tidy or play when asked. In the ICF it sits under d210 (undertaking a single task) and is a foundational executive-function skill. For children aged about 3–7 it is still developing, so needing prompts is common and not a diagnosis. Persistent, peer-different difficulty starting tasks is simply a signal that gentle, early support may help build confidence and independence.
Read the answer AnswerWhat is the Cognitive area of child development?
The cognitive area of child development is how a child's mind grows — attention, memory, problem-solving, imagination and early number and letter awareness. In the WHO ICF framework it sits within mental functions (b1). It is not about being clever or slow, but the everyday thinking that lets a child explore, play and learn. Noticing where a child is, without worry, helps you support the next step, and early review protects confidence and a love of learning.
Read the answer AnswerSpecial Education vs Remedial Education for Children
Special education is a broad, ongoing, individualised approach for children with disabilities or significant learning differences — it adapts how, where and what a child is taught. Remedial education is narrower and time-bound: focused extra teaching to help a child catch up in specific skills such as reading or maths. Special education adapts the system to the child; remedial education strengthens a specific skill so the child can rejoin the pace. The two can overlap, and a structured review helps you choose.
Read the answer AnswerTEACCH vs ABA for Children
TEACCH and ABA are both established autism support approaches with different philosophies. TEACCH is environment-led — it uses visual structure, predictable routines and organised spaces to help a child understand and succeed independently, adapting the world to the child. ABA is behaviour-led — it breaks skills into small steps and uses positive reinforcement to teach and strengthen specific abilities. Neither is universally better; the right fit depends on the child's profile and family goals, and many children benefit from elements of both.
Read the answer AnswerICD-11 Classification of Dyscalculia (6A03.2)
In ICD-11-MMS, Dyscalculia is coded 6A03.2 — Developmental learning disorder with impairment in mathematics — under the parent category 6A03 within neurodevelopmental disorders. It denotes persistent, significant difficulty acquiring mathematical skills not explained by intellectual disability, sensory or neurological impairment, or inadequate schooling.
Read the answer AnswerICD-11 Classification of Dysgraphia (6A03.1)
In ICD-11-MMS, dysgraphia is classified under 6A03 Developmental learning disorder as 6A03.1 — developmental learning disorder with impairment in written expression: persistent, age-disproportionate difficulty with spelling, grammar, punctuation and written organisation, not explained by intellectual, sensory, neurological or instructional factors.
Read the answer AnswerICD-11 Classification for Dyslexia (Reading Impairment)
In ICD-11-MMS, Dyslexia is coded 6A03.0 — Developmental learning disorder with impairment in reading, under the parent category 6A03. It denotes persistent, significant difficulty with reading accuracy, fluency and comprehension below age and ability expectation, not explained by intellectual disability, sensory impairment or inadequate schooling.
Read the answer AnswerICD-11 Classification of Global Developmental Delay
In ICD-11, Global Developmental Delay sits under LD24 (Disorders of intellectual development) as a provisional descriptor for children under 5 with significant delay across multiple domains who are too young for valid standardised cognitive assessment. It is a temporary, functioning-focused placeholder that prompts early intervention and later reclassification, not a fixed diagnosis.
Read the answer AnswerICD-11 Classification for Intellectual Disability (6A00)
In ICD-11-MMS, Intellectual Disability is classified as 6A00, Disorders of Intellectual Development, under Neurodevelopmental Disorders. It is defined by significantly below-average intellectual and adaptive functioning originating in the developmental period, with severity coded mild, moderate, severe or profound, plus provisional categories where standardised testing is not yet feasible.
Read the answer AnswerICD-11 Classification for School Readiness Gap
"School Readiness Gap" is a functional descriptor, not an ICD-11 diagnostic code. It is best mapped through the WHO ICF as a participation/functioning construct, with any underlying condition (e.g. developmental language disorder, ADHD) coded separately under ICD-11 if identified. Treat it as a screening flag warranting structured developmental profiling, not a label.
Read the answer AnswerICD-11 Classification for Specific Learning Disability
In ICD-11-MMS, Specific Learning Disability is classified as Developmental learning disorder, code 6A03, under Neurodevelopmental disorders, with subtypes for impairment in reading (6A03.0), written expression (6A03.1) and mathematics (6A03.2). Difficulties must persist at least six months despite intervention and not be better explained by intellectual, sensory or neurological causes.
Read the answer AnswerSNOMED CT Concept for Dyscalculia (Mathematics Impairment)
Dyscalculia is recorded in SNOMED CT as a distinct clinical finding concept for documentation, and classified in WHO ICD-11 under 6A03.2 (Developmental learning disorder with impairment in mathematics) for reporting. Because SNOMED CT identifiers are release-dependent, verify the active SCTID in your current national edition rather than hard-coding it.
