Nigerian newborns presenting with convulsion in University of Calabar Teaching Hospital, Calabar during the period January 1989 to December 1990 were prospectively studied to determine the aetiology and pattern of their seizures. There were 60 patients representing 4% of admissions into the Newborn Unit during the period. Birth asphyxia, infections and hypoglycaemia were the important identifiable aetiological factors which operated either singly (48% of cases) or in concert (in another 48%) of the infants. Detectable infections included meningitis and septicaemia caused predominantly by coliforms and Staphylococcus aureus. Hypocalcaemia and electrolyte imbalance did not feature. There was an unusually high prevalence (63% of cases) of the generalised type of seizures probably due to the high frequency of mixed aetiology. The mortality rate of 50% encountered appears to be related to the underlying aetiology and prematurity. Detectable caused of neonatal seizures in our environment appear to be potentially preventable by improved obstetric and neonatal care. There is dire need also to provide modern facilities for investigating newborn seizures in order to improve upon the diagnostic yield.
