Of 115 children with dyskinetic cerebral palsy (CP) in the Mersey regi
on, 17 were born at term and at an appropriate weight for age, and hav
e preserved cognitive abilities. 10 of these are likely to have sustai
ned intrapartum asphyxial brain-damage as the cause of their CP. In su
ch circumstances, a characteristic pattern is usually seen of severe f
etal distress occurring late in labour, severe but short-lived birth a
sphyxia and only mild or moderate hypoxic-ischaemic encephalopathy. Th
is clinical picture should be distinguished from the pattern of birth
asphyxia which precedes the development of spastic quadriplegic CP.
