Causes of developmental delay
Idiopathic - autism, Various Dysmorphic syndromes
Chromosomal abnormalities - Down's syndrome, Fragile X
Perinatal injury - Asphyxia, birth trauma
Prenatal injury - feral alcohol syndrome, intrauterine infection (TORCH)
Endocrine and metabolic defects - Congenital Hypothroidism, Phenylketonuria
Neurodegenerative disorders - Leucomalacia
Neurocutaneous syndrome - Sturge-Weber, neurofibromatosis, tuberous sclerosis
Post natal injury - Meningitis, non-accidentally injury, Neglect
Central nervous system malformation - Neural tube defects, hydrocephalus
Hx Q for development delay
Loss of skills suggests a neurodegenerative condition
Check if concerns about vision and hearing
PmHx - Alcohol consumption. Medica problems and medication during preg. Enquire about prematurity and neonatal complications
FmHx - learning difficulties and consanguinity
Global development delay
Delay in all milestones
Generally indicated significant learning disability
Need to refer to a development assessment team.
Examination of a child with developmental delay
Developmental skills all four areas of development as well as vision and hearing. Also alertness, responsiveness, interest in surroundings, determination and concentration; these all have positive influences on a child's attainment.
GI - Dysmorphic features, microcephaly (Fetal alcohol syndrome or intrauterine infections). Poor growth is common but may be due to Hypothroidism or non-organic failure to thrive - look for signs of neglect
Look for cafe au lait spots, Depigmentation patches and port wine stains which are indicative of neurocutaneous syndromes.
Hepatosplenomegaly suggests metabolic disorder
Neuro examination - abnormal tone, strength and coordination, deep tendon reflexes, clonus, cranial nerves and primitive reflexes and ocular abnormalities.
Ix for child with developmental delay
Urine screen for metabolic defect
Common cause of severe learning disability are
Fetal alcohol syndrome
Common cause of learning disabilities
Characteristic facial appearance - flatten bridge of nose, mid face hypoplasia, short palpebral fissures, long smooth philtrum
Course facial features
Tx with thyroxine
Inborn errors of metabolism
Single gene mutation
Autosomal recessive manner
Consanguinity is common
Presentation: developmental delay, neonatal seizures, hypoglycaemia, vomiting and coma.
Course features, microcephaly, failure to thrive, and Hepatosplenomegaly
Phenylketonuria is the commonest.and is screened for.
Characterised by progressive deterioration of neurological function
- heterogeneous and biochemical defects
- Chronic viral infections
- toxic substance
May have coarse features, fits and intellectual deterioration and microcephaly
Prognosis is bad as they continue to degenerate.
Heterogeneous group of disorders
Characterised by neurological dysfunction and skin lesions
some have severe leaving disability and other are normal
Sturge Weber syndrome
Presenting features of Autistic spectrum disorder
More in males
1% of population
Lack of pretend play, pointing out objects to another person, social interest, joint attention, social play, Response to name when called.
Language development is delayed or disordered
May be unusual social use of language
- intellectual disability
- other - ADHD, aggression and disruptive behaviour, anxiety disorders and depression, obsessive compulsive disorder, Tourette syndrome
Mx of ASD
Support and education
Early intervention programmes for behaviour, speech and special education
MDT - Paediatrician, psychiatrist, SP, Psychologist
Teaching social skills and friendship skills
Advice regarding educational options
DSM 5 ASD
A persistent deficits in social communication and social interaction across multiple environments
- 1 - deficits in social- emotional reciprocity or ranging
- 2 - deficits in non verbal communicative behaviours used for social interaction ranging eg abnormal eye contact, facial expression
- 3- deficits in developing, maintaining and understanding relationships, ranging eg making friends and sharing imagination play.
B - restricted, repetitive patterns of behaviour, interest or activities. At least 2 of the following
- 1 - stereotypes or repetitive eg lining up cars, echolalia
- 2 - Insistence on sameness, inflexibility
- 3 - Highly restricted, fixated interests that are abnormal in intensity or focus.
- 4 - Hyper or hypo reactivity to sensory input or unusual interest in sensory aspects of the environment.
C - present from early development
D - impairment
E - not explained by intellectual disability or global developmental delay.
Commonest genetic anomaly
Significant learning disability with implications for long term independent living.
Facial features of upward sloping palpebral fissures, fold of skin over epicanthic of the eyes, protruding tongue, flat occipital,
single palmar creases, mild to moderate developmental delay.
Associated medical - GI problems eg duodenal atresia, cardiac anomalies eg atrioventricular canal defects), Otitis media, squint, Hypothroidism, Atlanta-axial vertebral instability and leukaemia.
Attention deficit hyperactivity disorder
Most common neurodevelopmental disorder in childhood
Twice as common in boys then girl
Poor impulse control and limited sustained attention to task due to delays or deficit in executive brain function.
Poor emotional regulation
Commonly associated with - oppositional defiant disorder, anxiety disorder, learning disorders, autism spectrum disorder and tics.
Risk factors for ADHD
Very low birth weight
In-Utero exposure to neurotoxins eg alcohol
Environmental deprivation in infancy.
DSM 5 criteria for ADHD
A - persistent pattern of inattention and or hyperactivity - impulsivity that interferes with functioning or development characterised by 1 and or 2
- 1 - Inattention: 6 of the following for at least 6 months. Fail of Close attention and careless mistakes in school work, difficulty sustaining focus, not listening when spoken to, failure to follow instructions or finish task, difficulty organising, avoid thing that require sustained mental effort, often losses thing that are necessary for a task, easily distracted, forgetful in daily activities.
- 2 - Hyperactivity and impulsivity: 6 or more in the last 6 months. Fidgets, doesn't remain seated when it's expected, climbs and runs when it's inappropriate, unable to play quietly, is often on the go or driven, Talks excessively, blurts out answers before the question has been completed, difficulty waiting for their turn, often interrupts others.
B - Several inattentive or hyperactive symptoms were prior to 12yrs
C - several inattentive or hyperactive impulsive symptoms present in 2 or more settings
D - impair life
E - not due to other mental health condition
Principles of mx of Cerebral palsy
- physiotherapist - to minimise the effects of spasticity and prevent contractures.
- OT - advise of equipment, activities to encourage child's hand function.
- SP - to help feeding and language.
Orthopaedic problems -
- Paediatric management for the following issues
MDT with family put is essential
Good dental health
Assess and Address the associated impairment
- communication difficulties - electronic device
- Intellectual disability and specific learning problems - aid in school
- Manual limitation - OT etc
- Visual problems - visiual aids
- Hearing deficits
Assess and address health problems
- constipation, aspiration and sequent chronic lung disease, Growth. Gastro-oesophageal reflux (pain, bleeding, anaemia), under ended testes, epilepsy, osteopenia. Psychological and social factors.
Consequences of motor disorder
- Poor saliva control, incontinence, spasticity and dystonia. Orthopaedic problems.
- Physiotherapist, OT, SP, orthotists, social workers, nurse, psychologist and special education teachers
Tools to help assess child development
- The Goodenough 'Draw a man' test. - 4-10 years, one point for each item drawn. For each 4 points add one year to basal age of 3.
- Age and stages Questionaire - 4 - 60m. Looks at communication, GM, FM, problem solving,and personal adaptive skills
- Brigance screens - 0-90m -
- Parents evaluation of development status - 0-8yr - development and behavioural problems.

Behaviour modification -
Medication - stimulants - SE - appetitive suppression, anxiety, tics, withdrawn behaviour or subdue personality. Increase Heart rate, increase BP, loss of weight and decrease weight.
Positive parenting strategies
Types of cerebral palsy
Spastic cerebral palsy is the most common form where the injury is in the cerebral cortex or motor pathways.
Athetoid cerebral palsy are less common
Due to basal ganglia damage, Writhing movements, intelligence often normal, major physical impairment
Ataxic cerebral palsy are less common
Due to cerebral damage, poor coordination, ataxic gait.
Causes of cerebral palsy
Complication of prematurity
Postnatal - injury incurred before 2 yr old
Presentation of Cerebral palsy
Follow up of "at risk" infants, such as those born prematurely
Delayed motor milestones, particularly learning to sit, stand and walk
Asymmetric movement patterns, for example, strong hand preference early in life
Abnormalities of muscle tone particularly spasticity or hypotonia
Management problems, for example, severe feeding difficulties and unexplained irritability. Many other conditions present with these features.
Signs in the neonatal period
abnormal neuro exam
