How does birth asphyxia relate to cerebral palsy?

Severe birth asphyxia (causing HIE) can damage the developing brain and result in cerebral palsy - a permanent disorder of movement and posture.

However, birth asphyxia accounts for only a minority of cerebral palsy cases - most have antenatal/other causes (prematurity, infection, congenital/genetic factors) - so cerebral palsy should not be assumed to be due to intrapartum events.

Clinical relevance. Birth asphyxia can cause cerebral palsy but accounts for only a minority of cases - important for accurate counselling and not over-attributing it to birth events.

More Detail

Birth asphyxia and cerebral palsy

Birth asphyxia is one cause of cerebral palsy, but most cases have other origins.

The link

• Severe perinatal hypoxic-ischaemic injury (HIE) can cause permanent brain damage -> cerebral palsy (a permanent disorder of movement and posture) and other neurodisability (developmental delay, epilepsy).
• The classic pattern from term HIE is dyskinetic or spastic quadriplegic cerebral palsy.

Important caveat

• Birth asphyxia accounts for only a minority (a small proportion) of cerebral palsy.
• Most cerebral palsy has antenatal or other causes - prematurity, intrauterine infection/inflammation, congenital malformations, genetic factors, and postnatal causes.
• So cerebral palsy should NOT be automatically attributed to intrapartum asphyxia - specific criteria are needed to link the two.

Implication

• Important for counselling and medico-legal contexts - and for not over-attributing cerebral palsy to birth events.
