Q

what differentiates migraine from tension type headaches in children?

A
  • location (specific area vs generalised)
  • severity (migraine severe, tension mild/moderate)
  • type of pain (throbbing vs ache)
  • effect on activities (migrain stops ADL, tension headache doesn’t)
  • additional symptoms (migraine also presents with photophobia, vomiting, visual symptoms, weakness)

Q

what seizures are common in toddlers, and what nerve is involved?

Study These Flashcards
A

reflex anoxic seizures - mediated by vagus nerve

24
Q

name a few causes of provoked seizures in children

Study These Flashcards
A

hypoglycaemia
trauma
hypoxia
infection

25
what is a typical absent seizure?
abrupt loss of focus "daze", short lasting, can involve eye rolling or flickering
26
what is a tonic-clonic seizure?
seizure characterised by onset of myoclonic jerks, then tonic rigidity of body followed by clonic rhythmic jerking
27
what differentiates a psychogenic seizure from an epileptic seizure?
in psychogenic seizures patient is alert and able to communicate, vs epileptic seizure where patient loses consciousness
28
what are psychogenic seizures often associated with?
underlying psychosocial issues
29
what characterises infantile spasms?
stiff arms and legs reach upwards, head bends forwards | occurs in infants under 12 months
30
what types of epileptic seizures exist?
partial/focal | generalised
31
which type of epileptic seizure is more common in children?
generalised seizure "grand mal"
32
what is the most common cause of epileptic attacks in children?
idiopathic, no underlying cause
33
why are EEGs not reliable methods of detecting whether a child has epilepsy?
because someone with epilepsy can have a normal EEG (false negative), or EEG can show activity in someone with no epilepsy (false positive)
34
what are the possible types of seizures seen in epilepsy?
- simple/complex partial seizures - absent - tonic seizures - atonic seizures - clonic seizures - myoclonic seizures - tonic/clonic seizures
35
what is status epilepticus?
epileptic seizure lasting longer than 5 mins
36
what is the use of EEGs in diagnosing epilepsy?
- identify type of seizures - identify potential cause - identify epileptic syndrome
37
what is VNS?
vagal nerve stimulation - device which sends electric shock to vagus nerve to stop epileptic seizure
38
at which age does the posterior fontanelle close in a child?
around 3 months
39
at which age does the anterior fontanelle close in a child?
1-3 years
40
what is the definition of microcephaly?
<2 SD (standard deviation) - mild/moderate microcephaly | <3 SD (standard deviation) - severe microcephaly
41
what is the definition of macrocephaly?
>2 SD (standard deviation)
42
abnormalities of which head features can be found in children?
- head shape abnormalities | - head size abnormalities
43
what are the two types of head size abnormality in children?
microcephaly | macrocephaly
44
what causes head shape abnormalities in children?
abnormal closure of fontanelles
45
what types of abnormal head shape can be seen in children as a result of abnormal fontanelle closure?
brachycephaly (short head) scaphocephaly (boat head) plagiocephaly (flat head) craniosynostosis
46
how is skull growth measured in children?
occipitofrontal circumference (OFC)
47
when is the occipitofrontal circumference (OFC) measured?
- as routine measurement every visit from birth to 3 years old - if there is concern of neurological/developmental abnormalities
48
what does microcephaly normally indicate?
small/underdeveloped brain
49
what occurs in craniosynostosis?
fontanelles fuse too early, resulting in skull deformities
50
what is an important investigation to do if a child presents with weakness?
Creatine Kinase (CK)
51
what is Gower's sign, and what disease is it commonly seen in?
sign of proximal weakness (especially of hips/thighs) which causes child to stand up using arms/hands commonly seen in Duchenne's muscular dystrophy
52
what is the genetic inheritance of Duchenne's muscular dystrophy?
x-linked
53
name a few features of duchenne's muscular dystrophy
- delayed gross motor skills - proximal muscle weakness (pelvic/thigh) - calf (pseudo)hypertrophy - cardiomyopathy - respiratory problems - raised CK
54
what is myotonia?
inability to relax after voluntarily contracting a muscle
55
what is the most common inherited muscle disorder, and name one of its cardinal features
charcot-marie-tooth syndrome (hereditary motor/sensory neuropathy) presents with pes cavus
56
what is the difference between myopathy and myodystrophy?
myopathy - muscle weakness | myodystrophy - muscle destruction
57
what are myasthenic disorders?
disorders that affect chemical signalling at NMJ
