Dyslexia in India: prevalence and public-health burden
Dyslexia (ICD-11 6A03.0) is among the most common childhood neurodevelopmental conditions, affecting roughly 5–10% of school-age children internationally, with Indian school studies reporting specific learning disorder in the 3–10% range — several million young learners nationally. The public-health burden is large but largely preventable in its consequences: early screening and structured phonics-based remediation change reading trajectories. Population gains depend on universal early-grade screening, trained teachers, clear referral and embedded remediation.
Read the answer AnswerPrevalence & public-health burden of EBD in young children in India
Emotional & Behavioural Difficulties are among the most common early-childhood mental-health concerns in India, with community surveys placing overall child mental-health difficulties broadly in the 12–20% range and most cases under-identified. Given India's vast child population, the burden is significant — and largely reducible through systematic, non-stigmatising early screening and family-centred support.
Read the answer AnswerPrevalence and public-health burden of feeding and eating difficulties in India
India has no single national prevalence figure for feeding and eating difficulties (ICD-11 6B8Z), but international estimates of 25–45% in young children and Indian clinic data show a large, under-counted burden that intersects with undernutrition, family stress and missed early-intervention windows — making systematic early screening a public-health priority.
Read the answer AnswerFASD prevalence and public-health burden in India
India has no robust national prevalence estimate for Fetal Alcohol Spectrum Disorder (ICD-11 LD2F.00) in young children; the burden is under-counted owing to stigma, weak antenatal screening and no registry. FASD is lifelong but wholly preventable, making developmental surveillance and prevention the highest-value public-health levers.
Read the answer AnswerFine Motor Delay: Prevalence and Public-Health Burden in India
India lacks a single national prevalence figure for Fine Motor Delay in isolation; it sits within broader developmental-delay surveillance, where community studies range from a few percent to roughly one in ten. The burden is real but under-detected, and embedding low-cost fine-motor screening into existing ICDS and RBSK platforms is a high-return public-health strategy.
Read the answer AnswerPrevalence & Public-Health Burden of Genetic Syndromes in India
Genetic and chromosomal syndromes affect an estimated 2–3% of live births, translating to a large absolute burden across India's roughly 25 million annual births. Collectively they are a leading cause of childhood intellectual disability and developmental delay, with late identification and uneven regional access being key public-health gaps. The priority response is earlier screening and equitable, scalable early intervention.
Read the answer AnswerGlobal Developmental Delay in India: prevalence and public-health burden
Global Developmental Delay describes significant delay in two or more domains in under-fives. Indian estimates vary widely by tool and region, but the at-risk under-five cohort is vast, screening coverage is uneven, and early intervention measurably reduces lifelong burden — making population screening and referral the highest-leverage public-health action.
Read the answer AnswerGross Motor Delay in India: Prevalence & Public-Health Burden
India has no single national prevalence figure for gross motor delay in isolation; it forms a substantial share of overall developmental delay, observed in roughly 1 in 10 young children in community studies, concentrated where prematurity, low birth weight and undernutrition cluster. Its public-health value lies in being an early, visible, modifiable marker — best addressed through routine milestone surveillance and timely early intervention.
Read the answer AnswerHearing Impairment in young children: India's prevalence and public-health burden
Permanent childhood hearing loss affects roughly 1–6 per 1,000 newborns in India, making it among the most prevalent yet most preventable childhood disabilities. Because it is invisible until language fails, undetected loss disrupts speech, literacy and schooling — but early screening linked to the WHO/AAP 1-3-6 pathway makes most of that burden avoidable.
Read the answer AnswerHypotonia prevalence and public-health burden in India
There is no single validated national prevalence figure for hypotonia in young Indian children, because it is a clinical sign with many causes rather than one disease. It is, however, among the commonest motor presentations at early developmental assessment and a key gateway sign to treatable conditions — making early screening, referral and motor therapy its central public-health value.
Read the answer AnswerIntellectual Disability in India: prevalence and public-health burden
Intellectual disability (ICD-11 6A00) affects roughly 1–2% of young children in Indian community studies, though many cases go undetected before school age. The burden spans clinical, economic and educational dimensions; the highest-yield response is early, systematic developmental screening linked to structured early intervention.
Read the answer AnswerPrevalence and public-health burden of Motor Planning Difficulties in India
There is no validated India-specific prevalence figure for Motor Planning Difficulties; global estimates for Developmental Coordination Disorder sit around 5–6% of school-aged children. In India the public-health burden is driven less by raw prevalence than by late identification and high co-occurrence with speech, attention and sensory conditions. The priority for government partners is standardised screening and surveillance, not a single headline number.
Read the answer AnswerPrevalence and public-health burden of non-verbal / minimally verbal presentation in India
There is no single national prevalence figure for non-verbal / minimally verbal presentation in India, because it is a functional communication profile spanning autism, intellectual disability, hearing loss and severe language disorder rather than one diagnosis. Its public-health burden is read through late identification, uneven access to speech and AAC services, and caregiver load — and it is a high-yield target for frontline early screening because expressive communication responds strongly to early support.
Read the answer AnswerOppositional Defiant Disorder in India: Prevalence and Public-Health Burden
There is no robust national prevalence figure for Oppositional Defiant Disorder among young children in India; international estimates suggest roughly 3–5% of children. The real public-health burden is indirect — caregiver strain, school disengagement and downstream conduct difficulties when support comes late. The system priority is clinician-led screening and standardised measurement, not a precise but unsupported number.
Read the answer AnswerPersistent Toe-Walking: Prevalence and Public-Health Burden in India
India has no national prevalence registry for persistent toe-walking, so country-level figures are unreliable; international community studies place idiopathic toe-walking in the low single-digit percentages of young children. Most cases are benign and self-resolving — the real public-health burden lies in missed cases that develop calf and Achilles tightness, and in the small group signalling an underlying neuromuscular or developmental condition. Structured early screening within existing child-health checks is the highest-value response.
Read the answer AnswerPrevalence and Public-Health Burden of Prematurity-Related Developmental Risk in India
India has the world's largest number of preterm births — over 3 million yearly, ~13% of live births. As survival improves, a growing cohort carries raised developmental risk across communication, motor, cognition and learning. The burden is as much about post-NICU follow-up systems as biology, making universal developmental surveillance with corrected age a high-return public-health investment.
Read the answer AnswerPrevalence and Public-Health Burden of Rett Syndrome in India
Rett Syndrome (ICD-11 LD90.0) affects mainly girls at roughly 1 in 10,000–15,000 female births. India has no dedicated national registry, so prevalence is under-counted, but the figures imply hundreds of new cases yearly and tens of thousands living with it. The public-health burden lies in diagnostic delay, lifelong multi-domain support needs and high family caregiving load — making early identification and distributed therapy capacity the key system levers.
Read the answer AnswerSchool Readiness Gap in India: prevalence and public-health burden
The School Readiness Gap is the population-level distance between the skills children have at school entry and the skills schooling demands. In India's large annual birth cohort, several million children per year enter under-prepared — a largely preventable, modifiable burden best addressed through early developmental surveillance and early-years support, not after school failure.
Read the answer AnswerWhat is the prevalence and public-health burden of Selective Mutism among young children in India?
Selective Mutism (ICD-11 6B06) likely affects a meaningful share of young Indian children — international estimates suggest 0.5–0.8% — but India has no published national prevalence figure, leaving the burden largely invisible. The condition is under-recognised, often mistaken for shyness, and is a high-return target for early identification at school entry, where early structured therapy has strong outcomes.
Read the answer AnswerSelf-Regulation Difficulties in Young Children: India's Public-Health Burden
Self-regulation difficulties are common in early childhood in India yet largely invisible to the system because they rarely carry a single diagnostic label. As an upstream driver of school readiness, family stress and later mental health, they represent a high-yield, tractable target for early identification at population scale. Developmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional.
Read the answer AnswerPrevalence & public-health burden of Sensory-Based Feeding Selectivity in India
Sensory-Based Feeding Selectivity (ICD-11 6B83) is common but under-counted in India, hidden within "picky eating" and undernutrition data. International samples suggest 20–35% of young children show picky eating, with a smaller persistent clinical subset; India has no national figure. Its burden lies in micronutrient gaps, growth faltering, family stress and clustering with neurodivergence.
Read the answer AnswerPrevalence and Public-Health Burden of Sensory Processing Differences in India
There is no validated India-wide prevalence figure for sensory processing differences as a standalone entity; global community estimates run roughly 5–16% among young children, far higher alongside autism and other developmental conditions. In India the dominant public-health burden is under-detection, not absence of need — strengthening early developmental surveillance is the highest-leverage response.
Read the answer AnswerSeparation Anxiety Disorder in India: Prevalence and Public-Health Burden
Separation Anxiety Disorder (ICD-11 6B05) is among the commonest anxiety presentations of early childhood in India, with anxiety disorders broadly estimated in the low single digits to ~10% across community studies. Its public-health burden is driven by under-recognition, school disruption and family load — and it is highly responsive to early, structured support.
Read the answer AnswerSocial Communication Difficulties in India: Prevalence and Public-Health Burden
India lacks a single national prevalence figure for Social Communication Difficulties (ICD-11 6A01.22), but it falls within developmental communication disorders affecting roughly 1–2% of young children, with autistic social-communication differences adding substantially. The burden is heavy because identification is typically late, and early screening at frontline level offers among the highest returns in child public health.
