Overview
Possible causes for intellectual disability can be divided into genetic causes and environmental factors.
Causes
In less than 50% of individuals with mild ID, a specific cause is identified, and it increases to 75% in those with severe ID. [1]
Genetics
Down syndrome (Trisomy 21) is the most common genetic cause of ID, while Fragile X is the most common inherited cause of ID. [1]
Environmental Factors
Alcohol exposure during pregnancy, lead and other heavy metals, iodine deficiency, brain infections, congenital rubella syndrome, and cytomegalovirus infections, as well as hypoxic-ischemic injury, and periventricular hemorrhages all cause brain injury resulting in disability. [2]
