Even in cases of known etiology the line between "cause" and "effect" is not always clear, leading to difficulty in categorizing causes. Healthy development is not the result of a single influence. Common factors causing developmental disabilities include: • Brain injury or infection before, during or after birth • Growth or nutrition problems • Abnormalities of chromosomes and genes • Babies born long before the expected birth date - also called extreme prematurity • Poor diet and health care • Drug misuse during pregnancy, including excessive alcohol intake and smoking.
