Why does cultural-familial mental disability occur more frequently among the poor?

Question

Quizplus · Accepted Answer

Impoverished environments can be less intellectually stimulating, which can lead to cognitive deficits and a higher incidence of cultural-familial mental disabilities. This is often exacerbated by limited access to educational and healthcare resources. Poor nutrition can also contribute to intellectual disabilities, but PKU specifically is a genetic disorder that is not directly caused by poor nutrition. Chromosomal abnormalities are not more common in the lower classes, and while sexually transmitted diseases can cause intellectual disabilities, they are not the primary cause of cultural-familial mental disability.
