Q

define median age and limit age

A

Q

what are the 5 primitive reflexes?

A
  • Stepping (baby appears to take steps when held upright)
  • Moro (response to sudden loss of support, when infant feels as if it is falling, involves arm abduction, adduction, crying)
  • Grasp
  • Asymmetric tonic reflex (which way babies head is turned, arm outstretches)
  • Rooting (stroke baby’s cheek, causes baby to turn and open mouth)

  2. fixes and follows visually
  3. joins words
  4. symbolic play
A
  1. 18 months
  2. 3 months

21
Q

what is delay?

A

slow acquisition of skills

may occur in one or more domain

22
Q

what is it called when one domain is affected? or more than 2?

A

One domain affected = domain-specific

>+2 domains affected = global

23
Q

what is it called when all domains are affected equally? or differently?

A

All domains affected equally = consonant delay

All domains affected differently = dissonant delay

24
Q

what is disorder?

A

maldevelopment of a skill

25
Q

what are some causes of abnormal development?

A
  • abuse, trauma, drugs, infection
  • autism, deficits in development
  • malnutrition, cerebral palsy
26
Q

when does the delay present?

A
  • routine surveillance
  • identified risk factors
  • parents/HCPs worried
  • oppurunisitic worries raised
27
Q

what are the causes of abnormal development antenatally? (ask in history)

A
  • illness/ infections
  • medications
  • drugs
  • environmental exposures
28
Q

what are the causes of abnormal development at birth?

A
  • premature

- prolonged/ complicated labour

29
Q

what are the causes of abnormal development post-natally?

A
  • illness/ infections

- trauma

30
Q

what are the causes of abnormal development linked to consanguinity?

A

inc. chance of chromosomal/ autosomal conditions

31
Q

what examinations should you carry out to assess abnormal development?

A
  • growth parameters: height, weight, HC
  • dysmorphic features
  • neurological exam
  • skin exam
  • standardised exam assessments
32
Q

where is cerebral palsy?

A

disorder of movement and posture due to a non-progressive lesion of motor pathways

33
Q

what are the features of cerebral palsy?

A
  • manifestations merge over time

- reflects the balance b/ normal and abnormal cerebral maturation

34
Q

what is the most common cause of motor impairment in children?

A

cerebral palsy

35
Q

what are the causes of cerebral palsy?

  • hypoxic ischaemia injury at birth (10%)
  • postnatal origin = infection/ trauma (10%)
36
Q

what is the presentation of cerebral palsy?
