A

Spastic CP.

23
Q

What are the features of spastic diplegia?

A
  • Most common in preterm

A
  • Injury to thalamus, basal ganglia
  • Severe hypoxia
  • Kernicterus
  • Neurometabolic or neurogenetic disorders
25
What are common treatment strategies for spasticity?
* Pharmacological (e.g., Baclofen, Botulinum toxin) * Non-pharmacological (e.g., Physiotherapy, Occupational therapy)
26
What is the purpose of therapeutic hypothermia in infants with HIE?
To prevent Cerebral Palsy.
27
What is the Gross Motor Function Classification System (GMFCS)?
A tool to categorize the gross motor skills of children and young people with cerebral palsy into different levels.
28
What is the Manual Ability Classification System (MACS)?
A tool to categorize the ability of children with cerebral palsy to handle objects in everyday activities.
29

43%.
30
What percentage of children with CP have an intellectual disability?
1 in 2.
31
What are the treatment considerations for non-verbal children with CP?

32
What are the clinical findings and types of CP based on brain lesions?
* Spastic CP * Dyskinetic CP * Ataxic/Hypotonic CP * Mixed CP
33
True or False: All children with CP have cognitive impairments.
False.
34
Fill in the blank: The motor defect in CP largely depends on the _______.
[location of the brain lesion].
35
What is the primary pharmacological treatment for dystonia?
Botulinum toxin IM injection ## Footnote Botulinum toxin is often used for its muscle-relaxing effects in dystonia treatment.
36
Name two oral medications used to manage dystonia.
* Oral Valium * Oral clonazepam ## Footnote These medications are benzodiazepines that can help reduce muscle spasms.
37
What non-pharmacological treatments are available for dystonia?
* Physiotherapy * Occupational therapy * Orthotics * Orthopaedic surgery * Selective dorsal rhizotomy ## Footnote These treatments focus on improving function and quality of life.
38
What is an antidystonic drug that has anticholinergic properties?
Trihexyphenidyl ## Footnote This drug is used to reduce dystonia by adjusting neurotransmitter levels.
39
What is the overall survival rate of children with CP until the age of 20?
90% ## Footnote This statistic indicates a significant survival rate for children with cerebral palsy (CP).
40
At what age do most adults with CP begin to show age-related changes and diseases?
Earlier than typical populations ## Footnote This reflects the increased health challenges faced by individuals with CP.
41
What percentage of children with mild cognitive deficit survive until age 38?
95% ## Footnote This statistic highlights the prognosis for children with less severe cognitive challenges.
42
What are the 'F-words' in child development for children with CP?
Focus on six key areas of child development ## Footnote More details can be found at the CanChild website.
43
True or False: Most adults who have CP are under the age of 45.
False ## Footnote Most adults with CP are actually over the age of 45.
44
What is the role of gabapentin in the treatment of dystonia?
It is used as an adjunctive treatment ## Footnote Gabapentin is often used to help manage neuropathic pain and may assist in reducing dystonia symptoms.
45
What surgical intervention is mentioned for treating dystonia?
Deep brain stimulation ## Footnote This invasive procedure is aimed at modulating brain activity to alleviate symptoms.
46
Fill in the blank: The overall survival rate for children with CP until age 20 is _______.
90% ## Footnote This statistic underscores the improved lifespan for children with CP.
