Causes & influences
What are the known contributing factors for Developmental Trauma in early childhood?
Developmental trauma in early childhood arises from chronic, cumulative adversity within the caregiving relationship — abuse, neglect, disrupted attachment, caregiver mental illness and household dysfunction — operating across relational, familial, biological and community levels. Risk is dose-dependent and buffered by attuned caregiving.
Read the answer AnswerContributing Factors for Down Syndrome in Early Childhood
Down syndrome (ICD-11 LD40.0) arises from an extra chromosome 21 present at conception — advancing maternal age is the chief causal factor, with full trisomy, translocation and mosaicism as mechanisms. In early childhood, the relevant 'contributing factors' are modifiable comorbidities — cardiac, hearing, thyroid, vision, sleep and motor — that shape developmental trajectory and respond to early intervention.
Read the answer AnswerContributing Factors for Dyscalculia in Early Childhood
Dyscalculia (ICD-11 6A03.2) is multifactorial: heritable genetic risk, atypical intraparietal-sulcus and core number-sense function, and domain-general deficits in working memory, processing speed and attention are the most replicated contributors. Perinatal factors (prematurity, low birth weight) and instructional environment modulate expression rather than cause it alone.
Read the answer AnswerContributing factors for Dysgraphia in early childhood
Dysgraphia in early childhood is multifactorial: heritable neurodevelopmental variation, fine-motor and visuomotor integration deficits, phonological/orthographic weakness, and limited working memory and executive control. Comorbid ADHD, DCD and prematurity amplify risk. Identification is appropriate from around age 6–8 after sustained instruction.
Read the answer AnswerContributing Factors for Dyslexia in Early Childhood
Dyslexia is multifactorial: substantial heritability and left-hemisphere neurobiological differences interact with cognitive-linguistic precursors (phonological awareness, RAN, verbal memory), early language and speech delay, perinatal risk, and environmental literacy exposure. These appear as risk markers before formal reading begins.
Read the answer AnswerContributing Factors for Emotional & Behavioural Difficulties in Early Childhood
Early-childhood emotional & behavioural difficulties are multifactorial: biological vulnerability (genetics, prematurity, prenatal exposures), difficult temperament, language delay, attachment and parenting quality, parental mental illness, and family adversity. Risk is cumulative rather than single-cause, and relational factors are highly modifiable.
Read the answer AnswerContributing factors for feeding & eating difficulties
Early-childhood feeding and eating difficulties (ICD-11 6B8Z) are usually multifactorial, arising from medical/organic, oromotor and sensory, developmental, and relational/environmental factors — most often in combination. Structured multidomain assessment differentiates transient fussiness from difficulty needing intervention.
Read the answer AnswerWhat are the known contributing factors for FASD in early childhood?
Prenatal alcohol exposure is the single necessary cause of FASD (ICD-11 LD2F.00); there is no safe amount. Phenotype severity in early childhood is modulated by dose, timing and binge pattern, maternal age, nutrition and ADH genetics, co-exposures such as tobacco, fetal genetic susceptibility, and the post-natal environment.
Read the answer AnswerContributing Factors for Fine Motor Delay
Fine motor delay is multifactorial: prematurity, low birth weight and perinatal hypoxia; genetic and neuromuscular conditions; sensory and visual-motor integration deficits; and reduced environmental opportunity for graded hand use. Most well children show maturational variation, but asymmetric, regressive or red-flag-accompanied delay warrants structured assessment.
Read the answer AnswerContributing Factors for Genetic / Chromosomal Syndromes
Genetic and chromosomal syndromes stem from numerical, structural and single-gene variations. Key contributing factors include advanced maternal and paternal age, inherited or de novo variants, balanced parental rearrangements, and consanguinity. These are origins of the condition, not parenting failures, and warrant genetic counselling and parallel developmental support.
Read the answer AnswerContributing factors for Global Developmental Delay
Global Developmental Delay arises from multifactorial contributors across prenatal (genetic, metabolic, congenital, infective), perinatal (prematurity, hypoxic-ischaemic injury, kernicterus), postnatal (CNS infection, trauma, toxins, endocrine and nutritional) and environmental-social domains. A substantial share remains idiopathic despite work-up, so identifying factors guides targeted investigation rather than prognosis.
Read the answer AnswerContributing Factors for Gross Motor Delay
Gross motor delay is multifactorial: prematurity and low birth weight, perinatal hypoxic-ischaemic injury, cerebral palsy and neuromuscular disease, genetic-metabolic syndromes, central hypotonia, and environmental factors such as limited floor play. Regression, asymmetry or progressive weakness warrant urgent work-up rather than watchful waiting.
Read the answer AnswerContributing Factors for Hearing Impairment in Early Childhood
Childhood hearing impairment is multifactorial — genetic (around half of congenital cases, often GJB2), prenatal infection (notably CMV, rubella), perinatal factors (prematurity, hyperbilirubinaemia, hypoxia, ototoxic drugs) and postnatal causes (meningitis, chronic otitis media, trauma). Many appear on the JCIH risk register, underscoring universal newborn screening.
Read the answer AnswerContributing factors for hypotonia in early childhood
Hypotonia in early childhood is a clinical sign with central (most common), peripheral neuromuscular, and systemic/metabolic contributors. Localising the lesion via reflexes, strength and tone guides targeted investigation. Diagnosis and AbilityScore® are established only at a Pinnacle centre under clinician care.
Read the answer AnswerContributing Factors for Intellectual Disability
Intellectual disability (ICD-11 6A00) stems from genetic/chromosomal, prenatal, perinatal and postnatal contributors, often multifactorial and cumulative. Aetiology guides investigation but should never delay developmental surveillance and early intervention.
Read the answer AnswerContributing Factors for Motor Planning Difficulties
Motor planning difficulty in early childhood is multifactorial: prematurity, low birth weight, perinatal hypoxic-ischaemic insult and genetic/familial loading interact with atypical maturation of parieto-cerebellar and corticostriatal networks. It is a final common pathway rather than a single cause, and warrants structured developmental assessment.
Read the answer AnswerContributing factors for non-verbal / minimally verbal presentation
Non-verbal / minimally verbal presentation is a final common pathway with several contributors: hearing impairment, global developmental delay or intellectual disability, autism spectrum disorder, childhood apraxia and motor-speech disorders, developmental language disorder, and structural or neurological causes. Audiology comes first; many children carry more than one factor. A clinical AbilityScore and diagnosis are formed only at a Pinnacle centre.
Read the answer AnswerContributing Factors for ODD in Early Childhood
ODD in early childhood is multifactorial: child temperament and self-regulation deficits, harsh or inconsistent parenting and coercive family cycles, and psychosocial adversity converge transactionally. Risk is cumulative and correlational, not deterministic; protective parenting strongly moderates outcome.
Read the answer AnswerContributing Factors for Persistent Toe-Walking
Persistent toe-walking is a diagnosis of exclusion. Contributing factors cluster into neurodevelopmental associations (autism, sensory-processing, language and global delay), neuromuscular/orthopaedic causes to exclude (cerebral palsy, Duchenne, tethered cord, contracture), and a familial/idiopathic pattern with secondary tendo-Achilles shortening.
Read the answer AnswerContributing factors for prematurity-related developmental risk
Prematurity-related developmental risk is graded by gestational age and birthweight and compounded by IVH/PVL white-matter injury, bronchopulmonary dysplasia, sepsis, NEC, ROP and sensory injury, plus nutritional and socio-environmental modifiers. Risk is not binary; corrected-age surveillance de-risks most preterm children.
Read the answer AnswerKnown contributing factors for Rett Syndrome
Classic Rett syndrome is a monogenic, X-linked disorder caused in over 90% of cases by de novo MECP2 mutations on Xq28 — not by parenting, perinatal events or environment. Atypical variants involve CDKL5 and FOXG1. Contributing factors are genetic and molecular; recurrence risk is low. Refer for paediatric neurology and MECP2 testing.
Read the answer AnswerContributing Factors for the School Readiness Gap
The School Readiness Gap is multifactorial — arising from child-level factors (speech-language or global delay, sensory impairment, regulation and attention difficulties, prematurity), family and environmental factors (low language exposure, socioeconomic disadvantage, adverse experiences), and systemic factors (limited quality early education, late screening). Most contributors are modifiable with early identification.
Read the answer AnswerContributing Factors for Selective Mutism
Selective Mutism is multifactorial: behavioural inhibition, a family history of anxiety, co-occurring speech-language difficulties or bilingual demand, and anxious family interaction patterns. Silence is negatively reinforced and maintained by reduced expectation. Refer when setting-specific mutism persists beyond a month of school entry.
Read the answer AnswerWhat are the known contributing factors for Self-Regulation Difficulties in early childhood?
Self-regulation difficulties in early childhood stem from interacting biological, relational and environmental factors — temperament, prematurity, sensory and arousal differences, inconsistent co-regulation, caregiver stress, and toxic stress or adversity. These are cumulative and modifiable, with responsive caregiving the key protective mechanism. Diagnosis is formed only at a Pinnacle centre under clinician care.
