Prematurity is probably the major factor associated with brain damage in ne
wborns. Our growing knowledge of the biochemical mechanisms leading to the
onset of labour at term allows the biochemical correlates of the epidemiolo
gical risk factors for prematurity to be understood. Infection is the major
cause of early preterm labour and is now recognised to be a major cause of
fetal cerebral damage leading to cerebral palsy. Only some 5% of cerebral
palsy is due to intrapartum asphyxia at term. This may occur due to an obst
etric catastrophe or through inadequate placental function leading to chron
ic intrapartum asphyxia. Copyright (C) 2001 S. Karger AG. Basel.
