Multiple births are also known to be more prevalent in cerebral palsy than single births.

Risk Factors

Risk factors for CP can happen before birth, during birth, or after birth. Before birth, risk factors are often maternal cases and they include: the delayed onset of menstruation, irregular menstruation, or long inter-menstrual intervals. These are associated with CP because they may cause preterm births, which leads to CP. Another risk factor that can occur before birth is if the mother has certain medical conditions, such as seizures, intellectual disability, or thyroid disease. The risk factors during pregnancy are Pre-eclampsia, which is when the mother has high blood pressure and protein in urine, mothers receiving hormone or oestrogen, bleeding of the birth canal, and multiple pregnancies. Multiple pregnancies are thought to raise the risk of CP because they may cause birth defects, poor uterus growth, and preterm delivery. During labour, risk factors are: an elongated second stage of labour, an emergency C-section, premature separation of the placentia, and an unorthodox position of the fetus. The risk factors at birth are: low placentia weight, low birth weight, and short gestation length. According to Reddihough and Collins, 2003, these factors are thought to cause abnormal growth of the motor cortex, which leads to CP. After birth, a variety of risk factors can increase the chance of CP and they are: seizures of the newborn, respiratory disease, and preterm infant. Risk factors of CP are not just in the birth process but also in ethnicity and economic status. In terms of ethnicity black infants are 29% more likely to be diagnosed with CP than white infants. The reason for this is because black infants have higher rates of low birth weights than whites. Individuals with low socioeconomic status have an increased risk of CP.
