Q

What is the growth of nervous system from child to adult?

A

• Child’s brain constantly undergoes organization in function and
myelinization – full impact of insult not immediately apparent
• Open sutures and fontanels – early signs of increased in intracranial
pressure may not be apparent in infant

Q

what are the laboratory studies and diagnostic tests for neurological disorders?

A

• Blood studies – FBC, blood culture, test for toxic substance
• Urinalysis – infection or toxicology
• Lumbar Puncture (LP) – measure presses and obtain CSF
for chemistries and detect infection
• Radiography – skull fractures
• Electroencephalogram (EEG)– abnormal electrical brain wave discharges
• Echoencephalography – abnormal structure
• Computer Tomography (CT) – tissue and structure
• Magnetic Resonance Imaging (MRI) – visualization of structure and tissue
features at more detail level
• Nuclear brain scan (radioactive contrast) – identifies focal brain lesion,
CSF pathway

18
Q

What is generalised seziure?

A 
• Tonic refers to the muscle
becoming stiff
• Clonic means the muscles in
the arms and legs contracts
repeatedly to produce jerking
movements
19
Q

What is focal or partial seizure?

A 
• Abnormal discharge occurs in
only one area of the brain
• Eg. Motor,
somatosensory/special
sensory symptoms
20
Q

What are the subtle clinical manifestations of neonatal seizures?

A
  • Sucking, lip smacking or other oral-buccal-lingual movement
  • Bicycling or pedaling movement
  • Rhythmic ocular movements eg. Horizontal eye deviation
  • Occasionally apneic spells
21
Q

What is the management for neonatal seizure?

A
  • Infection
  • Electrolyte derangement
  • Metabolic abnormalities
22
Q

What is febrile seizure?

A

Febrile seizures are seizures or convulsions that occur in young children and are triggered by fever.

  • Seizures occurs when a child’s temperature rises to 38.5 degrees celcius or more
  • Affecting about 5% of all children
  • Occur in children aged 6 months to 6 year
  • Tend to run in families
23
Q

What is simple febrile seizure?

A
  • Generalized seizures last less than 15mins
    – typically 1-2mins is a tonic clonic
  • One occurrence per day
24
Q

What is complex febrile seizure?

A
  • Seizures last longer than 15mins
  • Occur multiple times a day
  • Or are partial seizures
25
Q

What is hydrocephalus?

A

Hydrocephalus is an abnormal buildup of fluid in the ventricles (cavities) deep within the brain

26
Q

what is congenital hydrocephalus?

A

It usually results from a defect,

such as Chiari’s malformation, also associated with spinal bifida

27
Q

What is acquired hydrocephalus?

A

usually the result of an injury or illness
• Acquired hydrocephalus results from space-occupying lesion:
- Hemorrhage
- Intracranial infection

28
Q

Treatment for hydrocephalus?

A

Direct removal of obstruction and insertion of

ventriculoperitoneal shunts to provide primary drainage of CSF to an extracranial compartment, usually peritoneum

29
Q

Major complication for hydrocephalus?

A

Infections and malfunction

30
Q

What is cerebral palsy?

A

A group of disabilities caused by injury or insult to the brain
- Either before or during birth
- In early infancy
• Most common permanent disability of children

31
Q

What are the classifications of cerebral palsy? (CP)

A
  1. Spastic ( Hypertonic )
  2. Mixed
  3. Athetoid ( Non-spastic or dsykinetic )
  4. Hypotonic
  5. Ataxic
32
Q

What is spastic cerebral palsy (70%) ? or also known as hypertonic palsy

A

Abnormal patter of posture and/or movement,
increased tone, pathological reflexes

most individuals with this type experience high muscle tone and exaggerated, jerky movements

33
Q

What is athetoid cerebral palsy? ( dsykinetic )

A

This type causes issues with involuntary movement in the face, torso, and limbs.

Athetoid cerebral palsy is characterized by a combination of hypotonia (loosened muscles) and hypertonia (stiffened muscles) which causes muscle tone to fluctuate.

Involvement of basal ganglia and extra-pyramidal
tracts. Involuntary, uncontrolled, recurring stereotyped movement

34
Q

What is ataxic palsy?

A

This type of cerebral palsy causes ataxia and issues with balance, coordination, and voluntary movement.

Ataxic cerebral palsy is caused by damage to the cerebellum, which is responsible for coordinating physical movement. Individuals with ataxic cerebral palsy often experience tremors and a reduction in muscle tone.

Wide-based gait, rapid repetitive movement and
disintegration of movement in the upper extremities when child
reaches for object

35
Q

What is hypotonic ( atonic cerebral palsy )?

A

This cerebral palsy type is classified by low muscle tone that causes loss of strength and firmness, resulting in floppy muscles.

Instability and floppiness in muscles caused by hypotonic cerebral palsy can cause a child to miss developmental milestones such as crawling, standing, or walking.

36
Q

What are the symptoms of spastic CP?

A

Common symptoms of spastic cerebral palsy include:

Abnormal walking
Awkward reflexes
Contractures (permanently tightened muscles or joints)
Stiffness in one part of the body

37
Q

What are the symptoms of dyskinetic CP?

A

Common symptoms of athetoid cerebral palsy include:

Feeding issues
Floppiness in the limbs
Problems with posture
Stiff or rigid body

38
Q

What are the symptoms of ataxic?

A

Common symptoms of ataxic cerebral palsy include:

Poor coordination
Problems with depth perception
Shakiness and tremors
Speech difficulties
Spreading feet apart when walking
39
Q

What are neuromuscular disease?

A
  1. Floppy infant

2. Neuromuscular disease

40
Q

Floppy infant

A

Decreased muscle tone
• Decreased muscle tone – down syndrome
• Neonate with decreased muscle tone – assume a “frog leg” posture with his legs abducted and
at least partially extended at the hips

41
Q

What is neuromuscular disease?

A 
Characterized by:
• Hypotonia
• Weakness
• Decreased deep tendon reflexes
• May involve the anterior horn cells, peripheral nerve neuromuscular junction or the muscles
42
Q

What is muscular dystrophy?

A

Progressive degeneration and weakness of skeletal muscles from infection or cardiopulmonary failure
could lead to death, usually in adolescence.
Pathophysiology: Absent of dystrophin (protein) in the muscle

43
Q

What is the nursing management for muscular dystrophy?

A

• Promote optimal family function, multiple disciplinary therapeutic measures, and support child’s
need
• Prevent physical injury – provide safe environment, protective gear
• Prevent physical deformity – use prescribed braces and other devices, perform ROM exercise
• Promote mobility – age and condition appropriate motor activities
• Assess for signs of disorder progression and complication
• Adequate fluid and nutritional intake
• Medications – sedative, muscle relaxant and anticonvulsant
• Genetic counselling
