The causes of developmental disorders can be multifactorial. They can include:
1. Genetic Factors: Mutations or genetic anomalies, such as those seen in Fragile X Syndrome or Down Syndrome. 2. Prenatal Factors: Exposures during pregnancy, such as maternal infections, substance abuse, or lack of proper nutrition. 3. Perinatal Factors: Complications during birth, such as prematurity, low birth weight, oxygen deprivation, or physical trauma. 4. Environmental Factors: Postnatal influences like exposure to toxins, inadequate stimulation, or lack of proper care and nutrition.
