Cerebral palsy Flashcards
What is cerebral palsy?
Permanent neurological problems resulting from bran damage at birth
Not progressive but changes due to growth and development
Huge range of severity
Antenatal causes of cerebral palsy
Maternal infections
Trauma during pregnancy
Perinatal causes of cerebral palsy
Birth asphyxia
Pre term birth
Post natal causes of cerebral palsy
Meningitis
Severe neonatal jaundice
Head injury
Type sof cerebral palsy
Spastic/pyramidal
Dyskinetic/athetoid/extrapyramidal
Ataxic
Mixed
What is spastic CP?
Hypertonia (increased tone) and reduced function due to UMN damage
Symptoms of dyskinetic CP
Problems controlling muscle tone
Hyper/otonia both
Causes atheotid movements and oro=motor problems
What part of brain is damages in dyskinetic CP
Basal ganglia
What is damaged in spastic CP
UMNs
Sympotms of ataxic CP + where damaged
Coordinated movement problems
Cerbellum
Patterns of CP
Monoplegia, hemiplegia, diplegia quadriplegia
What is differnece between diplegia and quadraplegia
Four limbs affected in both
Diplegia - four limbs are affected but mostly legs
Quadraplegia - four limbs are affected more severely often with seizures, speech disturbacnes and other impairments
Monoplegia vs hemiplegia
ONe limb affected -mono
Hemi - one side of body affected
What is hypoxic ischaemic encephalopathy
Perinatal asphyxia causing acute brain injury due to systemic hypoxia and decerased cerebral blood flow
Signs and sympotms of cerebral palsy during development
Failure to meet milestones
Increased or decreased tone, generally or in specific limbs
Hand prefernece below 18 months
Problems with coordination speech or wlaking
Feeding or swallowing problems
Learning difficulties
What does a high stepping gait suggest is damaged?
Foot drop or LMN lesion
What does a waddling gait suggest?
Indicates pelvic muscle weakness due to myopathy
Anatalgic gait (limp) suggests?
Localised pain
What lesion does a broad based gait/ ataxic gait suggest?
Cerebellar lesion
Muscle bulk LMN vs UMN
Bulk preserved in UMN
Reduced bulk with fasciculations
What causes hypertonia?
UMN lesion
What causes hypotonia?
LMN lesion
LMN vs UMN which more dramatically reduces power?
LMN
Reflexes UMN vs LMN
UMN - brisj
LMN - reduced
What causes hemiplegic/diplegic gait
Increased muscle tone and spasticity in the lefs
What happens in a hemiplegic/diplegic gait?
Leg extended with plantar flexion of feet and toes -> swing leg large semicircle when moving leg behind to front
