CEREBRAL PALSYCEREBRAL PALSY

CEREBRAL PALSYCEREBRAL PALSY

Chronic disability of central nervous system origin characterised by aberrant

control of movement of posture, appearing early in life and not the result of progressive neurological

disease.

Spastic: Upper motor neurone lesion.

Hemiplegia: UMNL of one side of body.

Diplegia: UMNL of all four limbs but legs more than arms. May be symmetric

or asymmetric.

Quadriplegia: Equal involvement of arms and legs.

Rigidity: ↑ tone throughout range of movement.

Dyskinesia: Involuntary movements and changes in muscle tone. Damage to basal ganglia and

extraphyomides pathways.

Athetosis: Slow writhing movements of limbs. Extension and fanning of fingers and extension of wrist.

Chorea: Quick jerky movements of trunk and prox, limb muscles.

Paraplegia: Legs involved only.

Double Hemiplegia: Bilateral UMNL. Arms and legs. Also pseudobulbar palsy.

Monoplegia: One Limb.

Early Signs of Cerebral PalsyEarly Signs of Cerebral Palsy1. Birth History

a) Prematurity.b) Seizures.c) Low apgars.d) Intracranial haemorrhage.e) Periventricular leucomalacia.

2. Delayed Milestones3. Abnormal Motor Performance

a) Handedness.b) Reptilian crawl.c) Toe waking.

Early Signs of Cerebral PalsyEarly Signs of Cerebral Palsy

4. Altered Tone.

5. Persistence of primitive reflexes.

6. Abnormal posturing.

Prenatal Associations with Prenatal Associations with Cerebral PalsyCerebral Palsy

Placental insufficiency.Brain malformation.Congenital infection.Chromosomal defects.Exposure to toxins.Abnormality of neuronal migration.

PLACENTAPLACENTA

1. Correlation of placenta infarction or thrombosis with ischaemic lesions in the brains of babies who have suffered intrauterine or early neonatal deaths.

2. 11 / 15 placental slices from 15 patients with Cerebral Palsy contained thrombosis.

THROMBOPHILIA & THROMBOPHILIA & CEREBRAL PALSYCEREBRAL PALSY

a) Thrombosis in placental circulation.b) Coagulation abnormalities in mother and

foetus – Factor V Leiden Mutation which is responsible for activated protein C resist (APCR).

c) Foetal and neonatal stroke have been reported in presence of maternal anticardiolipin antibodies.

d) 20 / 31 children with cerebral palsy had one or more disorders of coagulation in neonatal blood spot analysis.

ANTENATALANTENATAL

Maternal infection & cerebral palsy

a) Maternal fever> 38oc + Chorioamnionitis associated with ↑ risk of cerebral palsy.

b) ↑ Inflammatory markers in children with cerebral palsy.
