Median neurofilament and glial fibrillary acidic protein concentrations in
the cerebrospinal fluid of 18 infants with posthaemorrhagic ventricular dil
atation were 20-200 times higher than control values. S-100 protein in cere
brospinal fluid was four times higher than control values. Glial fibrillary
acidic protein concentrations correlated with death or disability and with
parenchymal lesions but not with shunt dependence.
