Cerebral Palsy Flashcards
What is cerebral palsy (CP)?
Cerebral palsy (CP) is the name given to the permanent neurological problems resulting from damage to the brain around the time of birth.
It is not a progressive condition, however the nature of the symptoms and problems may change over time during growth and development.
There is huge variation in the severity and type of symptoms, ranging from completely wheelchair bound and dependent on others for all activities of daily living, to para-olympic athletes with only subtle problems with coordination or mobility.
What are the causes of CP?
Note: antenatal, perinatal and postnatal
Antenatal:
- Maternal infections
- Trauma during pregnancy
Perinatal:
- Birth asphyxia
- Pre-term birth
Postnatal:
- Meningitis
- Severe neonatal jaundice
- Head injury
What are the 4 different types of CP?
- Spastic
- Dyskinetic
- Ataxic
- Mixed
Briefly describe spastic CP
Hypertonia (increased tone) and reduced function resulting from damage to upper motor neurones.
Spastic CP is also known as pyramidal CP.
Briefly describe dyskinetic CP
Problems controlling muscle tone, with hypertonia and hypotonia, causing athetoid movements and oro-motor problems. This is the result of damage to the basal ganglia.
Dyskinetic CP is also known as athetoid CP and extrapyramidal CP.
Briefly describe ataxic CP
Problems with coordinated movement resulting from damage to the cerebellum.
Briefly describe mixed CP
A mix of spastic, dyskinetic and/or ataxic features.
Briefly describe the 4 patterns of spastic CP
Monoplegia: one limb affected.
Hemiplegia: one side of the body affected.
Diplegia: four limbs are affects, but mostly the legs.
Quadriplegia: four limbs are affected more severely, often with seizures, speech disturbance and other impairments.
Which type of CP is the most common?
Spastic CP accounts for 90%.
How does CP present?
Signs and symptoms of cerebral palsy will become more evident during development:
- Failure to meet milestones
- Increased or decreased tone, generally or in specific limbs
- Hand preference below 18 months is a key sign to remember for exams
- Problems with coordination, speech or walking
- Feeding or swallowing problems
- Learning difficulties
What does a hemiplagic/ diplegic gait indicate?
Indicates an upper motor neurone lesion.
What does a broad based gait/ ataxic gait indicate?
Indicates a cerebellar lesion.
What does a high stepping gait indicate?
Indicates foot drop or a lower motor neurone lesion.
What does a waddling gait indicate?
Indicates pelvic muscle weakness due to myopathy.
What does an antalgic gait (limp) indicate?
Indicates localised pain.
