causes of cerebral palsy during pregnancy
Infections during pregnancy â Mothers can pass infections to the fetus during pregnancy. Prenatal infections are most dangerous in the first few weeks after conception. German measles (rubella) and cytomegalovirus (CMV) during pregnancy are known causes of cerebral palsy. These viruses cause the motherâs immune system to release proteins that not only attack the infection, but also cause inflammation in the babyâs brain that interferes with normal development.
