• Leukomalacia: Softening or destruction of the white matter of the brain. Brain tissue that surrounds fluid-filled parts of the brain (ventricles) is destroyed. It tends to occur mainly in premature or newborn babies who have been deprived of oxygen or have poor blood flow to parts of the brain. Intrauterine infections and premature membrane rupture tend to predispose infants to this condition. This type of brain destruction can cause cerebral palsy. Severity of symptoms varies according to the degree of injury to the brain.
