Definition
Cerebral palsy is defined as a non-progressive disorder of cerebral
function involving posture and movement, dating to events in the prenatal,
natal, or neonatal period. It is often associated with epilepsy and abnormalities
of speech, vision and intellect resulting from a lesion or defect of the
developing brain.
The incidence of cerebral palsy is 4 /1000
population.
Causes of cerebral palsy
1- Antenatal causes
a- Intra-uterine
infections: TORCH.
b- Fetal anoxia,
maternal hemorrhage, placental insufficiency.
c- Maternal irradiations
of the pelvis.
d- Congenital
malformations of brain or vascular occlusion.
2- Intranatal causes
a- Birth
injury: intracranial hemorrhage, cerebral trauma.
b- Cerebral anoxia.
c- Marked low birth
weight infants and prematurity.
3- Postnatal causes
a- Intra-cranial infections:
meningitis, encephalitis, brain abscess.
b- Neonatal asphyxia.
c- Kernicterus.
d- Hypoglycemia.
Types of cerebral palsy
1- Spastic cerebral palsy
a- Spastic
hemiplegia
b- Spastic diplegia
c- Spastic
quadriplegia
d- Spastic
monoplegia and paraplegia
2- Extrapyramidal cerebral palsy
3- Ataxic cerebral palsy
4- Mixed types
Diagnosis
Thorough history and physical examination
should be performed to eliminate progressive disorders of the CNS.
· A baseline electroencephalogram (EEG)
and CT scan may be indicated
Prevention
· Tests of hearing and visual function
should be performed.
Prevention
Prevention of cerebral palsy is the ideal
approach of this problem and is accomplished through:
1- Prevention of maternal irradiation and unnecessary drug
intake.
2- Antenatal monitoring to prevent intrapartum asphyxia.
3- Prevention of birth trauma and perinatal asphyxia.
4- Prevention of hypoglycemia.
5- Prevention of low birth weight and its complications.
6- Proper management of neonatal jaundice.
Early diagnosis is
necessary in order to try to prevent secondary positional deformities.
Treatment
· Physiotherapy: prevents gross
contractures. Serial plastering and splinting are required to treat positional
deformity.
· Reducing abnormal muscle tone: small
regular doses of benzodiazepine may be useful in reducing the severity of
spasticity.
· Surgical procedures: to improve the
mobility.
· Speech therapy and hearing aids may be useful
if there is deafness.
