Most brain malformations begin long before a baby is born. Something damages the developing nervous system or causes it to develop abnormally. Sometimes it's a genetic problem. In other cases, exposure to certain medicines, infections or radiation during pregnancy interferes with brain development. Types of brain malformations include missing parts of the brain, abnormal growth of certain parts of the brain, and incomplete division of the brain
