Neuropathological observations in the sudden infant death syndrome: a brief survey of the literature.

Neuropathological abnormalities are found in the brains of many babies who die from Sudden Infant Death Syndrome. At least some of these are likely to be secondary to chronic hypoxia or other systemic or localized insults. The role of these 'secondary' abnormalities and of other findings such as maturational delay in the pathogenesis of the Syndrome remains uncertain.
