Quizplus · Accepted Answer

The more severe forms of intellectual disability are more likely due to organic causes, such as genetic/chromosomal abnormalities, brain malformations, or brain damage. Mild intellectual disability may have a wider range of causes, including cultural and environmental factors. Familial causes may be a factor in both severe and mild intellectual disability, while idiopathic (unknown) causes are relatively rare.
