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)

Q

what are the milestones in social, behaviour and play domain?

A
  • 6 weeks: smile responsively
  • 6-8 months: puts food in mouth
  • 10-12 months: wave bye, play peek a boo
  • 12 months: drink from cup with 2 hands
  • 18 months: can eat by themselves
  • 18-24 months: symbolic play
  • 2 years: potty trained
  • 2.5-3 years: parallel play
20
Q

what are the limit ages of:

  1. walking independently
  2. fixes and follows visually
  3. joins words
  4. symbolic play
A
  1. 18 months
  2. 3 months
  3. 2 years
  4. 2-2.5 years
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
what are some causes of abnormal development?
- abuse, trauma, drugs, infection - autism, deficits in development - malnutrition, cerebral palsy
26
when does the delay present?
- routine surveillance - identified risk factors - parents/HCPs worried - oppurunisitic worries raised
27
what are the causes of abnormal development antenatally? (ask in history)
- illness/ infections - medications - drugs - environmental exposures
28
what are the causes of abnormal development at birth?
- premature | - prolonged/ complicated labour
29
what are the causes of abnormal development post-natally?
- illness/ infections | - trauma
30
what are the causes of abnormal development linked to consanguinity?
inc. chance of chromosomal/ autosomal conditions
31
what examinations should you carry out to assess abnormal development?
- growth parameters: height, weight, HC - dysmorphic features - neurological exam - skin exam - standardised exam assessments
32
where is cerebral palsy?
disorder of movement and posture due to a non-progressive lesion of motor pathways
33
what are the features of cerebral palsy?
- manifestations merge over time | - reflects the balance b/ normal and abnormal cerebral maturation
34
what is the most common cause of motor impairment in children?
cerebral palsy
35
what are the causes of cerebral palsy?
- antenatal (80%): genetic syndromes, congenital infection - hypoxic ischaemia injury at birth (10%) - postnatal origin = infection/ trauma (10%)
36
what is the presentation of cerebral palsy?
- abnormal limb tone and delayed milestones - feeding difficulties - abnormal gait once walking - asymmetric hand function before 12 months - primitive reflexes persist
37
what are the types of cerebral palsy?
- 70%: spastic - 10%: ataxic hypotonic - 10% dyskinetic - 10% mixed pattern
38
what are the associated problems?
- learning difficulties - epilepsy - visual impairment - hearing loss - feeding difficulties - poor growth - resp probelms
39
how do you manage cerebral palsy?
- minimise spasticity | - manage associated symptoms
40
what is autism?
neurobiological disorder characterised by: - impairment of social interactions/ communication - reptitive and stereotyped patterns of behaviour, interests and activities
41
what are the comorbidites of autism?
- learning difficulties - attention difficulties - epilepsy
42
what is the criteria of development for attention deficit hyperactivity disorder
- Inattention - Hyperactivity - Impulsivity - Lasting >6 months - Commencing <12 years and inconsistent with child’s developmental level
43
how do they carry out diagnosis?
- Questionnaires - Exclude medical causes such as hyperthyroidism - Hearing deficiets - Identify risk factors and co-morbidities
44
what does ADHD lead to an inc. risk of?
- conduct disorder - anxiety disorder - aggression
45
what is the management of ADHD?
- Psychotherapy – behavior therapy - Family therapy, drugs - Diet – exclusion of some drugs
46
what are the causes of learning difficulties?
``` 25% no identifiable cause 30% chromosome disorder 20% other syndromes 20% post natal cerebral insults 1% metabolic or degenerative disease ```
47
what may learning difficulties present with?
- Reduced intellectual functioning - Delay in milestones early - Dysmorphic features and associated problems e.g. ADHD, epilepsy, sensory impairment - MDT for long-term follow up and school recognition
