Cerebral arterial infarction is a more common cause of neonatal seizures than has been previously appreciated. In 50 full-term newborns with seizures studied, 7 had cerebral infarction which was the second most common definable cause of seizures. We describe these 7 full-term infants with cerebrovascular accidents who presented with focal or generalized seizures. Obstetrical histories were normal in 5 of these patients. Their neurological examinations demonstrated lethargy and generalized hypotonia. Electroencephalograms demonstrated focal abnormalities in 4 infants. Computed tomographic scans in the first week of life showed infarctions in 6 newborns and in another at age 6 months. Neonatal stroke should be considered as a cause of seizures in a full-term newborn in spite of a normal obstetrical history and a nonfocal neurological examination.

Recent studies have suggested a causal and pathogenetic relationship between holoprosencephaly and anencephaly. In support of the proposed relationship we report a sibship that includes anencephalic male twins and a female infant with a severe form of alobar holoprosencephaly, radial aplasia, and oligodactyly. The upper limb and brain malformations are considered to represent aprosencephaly syndrome. The coexistence of anencephaly and aprosencephaly within a sibship suggests that XK aprosencephaly syndrome may be an autosomal recessive disorder.
