Cerebral Palsy Flashcards
What is Cerebral Palsy?
A disorder of movement and posture due a non-progressive lesion of the motor pathways in the developing brain.
Presentations of Cerebral Palsy
Abnormal tone in early infancy
Delayed motor milestones
Abnormal Gait
Feeding difficulties
Non-motor Symptoms of cerebral palsy
60% have learning difficulties
30% have epilepsy
30% will have a squint
20% will have hearing impairments
Causes of Cerebral palsy
80% are antenatal - cerebral malformations or congenital infections (rubella, CMV, Toxoplasmosis)
10% intrapartum - birth asphyxia or trauma
10% postnatal - IVH, meningitis, hyperbilirubinaemia or head trauma
Also linked strongly to low birth weight and prematurity.
Classification of Cerebral Palsy
70% spastic - pyramidal signs, hyperreflexia, increased tone and posture - can be hemiplegia, diplegia or quadriplagia Also Dyskinetic (involuntary, uncontrolled recurring movements), ataxic (abnormal pattern of movement with loss of muscular co-ordination). Also dystonic (hypokineasia and hypertonia) or choreoathetotic (hyperkinesia and hypotonic)
Management of Cerebral Palsy
Multidisiplinary approach is needed. Treat spasticity with oral diazepam, oral or intrathecal baclofen, botulinium toxin type A, orthopaedic surgery and selective dorsal rhizotomy (possibly DBS)
May also need analgesia and anticonvulsants as required
Incidence of Cerebral Palsy
2/1000 live births. Increased in LBW babies (59/1000 2,500gs) and decreases with gestational age (111/1000 before 28wks, 1.35/1000 after 36wks)
Secondary Impairments in Cerebral palsy
Feeding problems
Constipation
Asthma, reactive airways disease or upper airway obstruction
UTIs, skin breakdown or dental problems
Gross motor function classification system (GMFCS)
I - walks fine but limited in more advanced motor skills
II - walks independently but difficulties with walking outdoors/in the community
III - walks with mobility devices
IV - Self mobilises with limitations (uses power mobilisers)
V - self mobility is severely limited even with the use of supporting technology.
Long term motor consequences of Cerebral palsy
Spasticity and loss of motor control leading to muscle shortening, bony torsion and joint instability, degenerative arthritis
