Question

Quizplus · Accepted Answer

Mental retardation can be caused by a variety of factors, including genetics (single-gene and chromosomal disorders), infections, malnutrition, exposure to toxins or poisons, and problems before or during birth. Watching television, exposure to secondhand smoke, and drinking cow's milk before six months are not known causes of mental retardation. Inheriting a low IQ, lack of stimulation, and neglect can contribute to intellectual disability but are not the primary causes. Exposure to certain bacteria, fungal spores, or mouse excrement may cause other health problems but is not a major cause of mental retardation.
