Developmental Delay and Cerebral Palsy
Developmental delay, intellectual disability and cerebral palsy for MBBS: definitions, structured approach, GMFCS classification and multidisciplinary management, mapped to NMC codes PE3.1 to PE3.8.
This chapter covers developmental delay, intellectual disability and cerebral palsy, including definitions, a structured approach to the delayed child, and the multidisciplinary management of cerebral palsy. It stresses screening for treatable causes and the role of the child development unit.
High-yield: Developmental Delay and Cerebral Palsy
- Global developmental delay applies mainly below 5 years and requires significant delay in at least two developmental domains.
- Intellectual disability requires deficits in both intellectual and adaptive functioning with onset in the developmental period, not a low intelligence quotient alone.
- Adaptive functioning in everyday life, not the intelligence quotient value alone, is the clinical anchor for diagnosing intellectual disability.
- The approach to developmental delay is: confirm delay, classify domains, look for deviance or regression, assess hearing and vision, examine neurologically, search for treatable causes, and begin early intervention.
- Any developmental concern involving speech makes hearing assessment mandatory, and any motor delay makes assessment of tone quality mandatory.
- Developmental regression, infantile spasms, recurrent choking, failure to visually fix or absent response to sound require urgent escalation rather than routine follow-up.
- The most useful first prescription in developmental delay is often a written early-intervention plan rather than a drug.
- Cerebral palsy is a non-progressive disorder of movement and posture due to an early brain injury, and it is classified by motor type, topography and GMFCS level.
- Cerebral palsy motor types include spastic, dyskinetic, ataxic and mixed, with spastic being the most common.
- The Gross Motor Function Classification System (GMFCS) grades functional mobility in cerebral palsy from levels I to V.
- Cerebral palsy management is multidisciplinary, targeting function, comorbidities and participation rather than cure.
- Common comorbidities of cerebral palsy include epilepsy, intellectual disability, visual and hearing impairment, feeding difficulty and communication problems.
- Loss of milestones, progressive weakness, absent reflexes with hypotonia or organomegaly should not be labelled cerebral palsy without re-evaluation, as these suggest a progressive disorder.
- The District Early Intervention Centre and child development unit provide assessment, early intervention, parent training and school linkage for children with delay.
Classifying cerebral palsy
- **By motor type:** Spastic (most common), dyskinetic, ataxic or mixed.
- **By topography:** Monoplegia, hemiplegia, diplegia or quadriplegia.
- **By GMFCS level:** Levels I to V graded on functional gross-motor mobility.
- **Comorbidities:** Epilepsy, intellectual disability, sensory impairment and feeding difficulty.

Frequently Asked Questions
What is global developmental delay?
Global developmental delay is a term used mainly for children below 5 years who show significant delay in at least two developmental domains such as gross motor, fine motor, language, cognition, or social skills.
How is intellectual disability diagnosed?
Intellectual disability requires deficits in both intellectual functioning and adaptive functioning with onset during the developmental period. Adaptive functioning in daily life, not the intelligence quotient number alone, is the clinical anchor.
How is cerebral palsy classified?
Cerebral palsy is classified by motor type (spastic, dyskinetic, ataxic or mixed), by topography (hemiplegia, diplegia or quadriplegia), and by the Gross Motor Function Classification System levels I to V, always noting comorbidities.
When is a diagnosis other than cerebral palsy suspected?
Loss of previously acquired milestones, progressive weakness, absent reflexes with hypotonia, episodic encephalopathy or organomegaly point to a progressive neurologic or metabolic disorder and should prompt re-evaluation rather than a cerebral palsy label.
