Poor or impoverished countries often have a greater number of children in their population structure and, consequently, a greater number of children with developmental disorders. In India, for example, 40% of the 1.3 billion inhabitants are children.
But in addition to the frequency of children, we also have an increased risk to children and adults. Well-established risks for development include everything from intoxications and infections during pregnancy, to the nutritional risks of pregnant women and babies, not only talking about nutritional deficits related to calorie deprivation, but also factors related to micronutrient deficiency. Thus, adding the risks increases the symptoms and diagnoses.
