Cerebral Palsy Flashcards
What does the term ‘palsy’ refer to?
Muscle weakness or paralysis
Includes conditions like Bell’s palsy, shaking palsy (Parkinson’s), and bulbar palsy.
What is the most common movement disorder in children?
Cerebral palsy
Affects about 1 in 500 births.
What are the types of cerebral palsy?
- Spastic cerebral palsy (70-80%)
- Dyskinetic cerebral palsy (10-20%)
- Ataxic cerebral palsy (5-10%)
- Hypotonic (3%)
- Mixed
What percentage of cerebral palsy cases are congenital?
90%
List some risk factors for cerebral palsy.
- Oxygen deprivation during birth
- Pre-term birth
- Genetics (minor factor)
- Twin births
- Low socioeconomic status (poor maternal nutrition)
- Low birth weight
- Maternal infection
- Perinatal stroke (in the baby) = brain bleed/ o2 deprivation during birth
Which part of the brain is primarily injured in spastic cerebral palsy?
White matter from the Motor cortex (upper motor neurons)
What is Spastic CP characterised by?
- Hypertonia (stiffness)
- Problems swallowing, speaking
- Vision problems
- Diplegia characteristic = “scissoring gait”
What are the types of hypertonia in spastic cerebral palsy based on limb involvement?
- Diplegia - mainly legs affected
- Hemiplegia – one side of the body
- Quadriplegia – all four limbs
What part of the brain is injured in Dyskinetic CP?
Damage to basal ganglia (so problems in controlling movement)
Brain regions involved in regulating motor function and inhibiting unwanted movements
What defines ataxic cerebral palsy?
Damage to the cerebellum causing problems with coordination and balance (drunk-like movements)
What are some common issues faced by individuals with cerebral palsy?
- Intellectual disability (in 20% of people, this is severe)
- Seizures
- Bone and joint problems - e.g. arthritis due to abnormal gait, fragile bones due to low exercise and curvature of spine
- Chronic pain - linked to bone/joint problems, GI tract issues (chronic constipation) and contractures (locking of joint)
True or False: Intellectual disability is caused by cerebral palsy.
False
What types of therapies are involved in the treatment of cerebral palsy?
- Physiotherapy
- Speech and language therapy
- Assistive technologies/ mobility aids
- Muscle relaxants eg. Diazepam, baclofen, Botox
- Surgery - Musculoskeletal (repair damaged joints or lengthening of tendons to correct scoliosis) or Selective dorsal rhizotomy (lesion motor pathways coming out of spine)
- Pain relief medication
- Anticonvulsant medication
What genetic neurodevelopmental disorder is characterized by a deletion of 27 genes on chromosome 7?
Williams syndrome
What are the key features of Angelman syndrome?
- Characteristic appearance = small head, skin in corner of eyes
- Seizures
- Ataxia
- Learning difficulties
- Uncontrolled laughter
- Affects brain regions = hippocampus (cognitive deficits - learning and memory), Cortex & cerebellum (motor deficits)
