Neither radiation nor lead nor DDT have these kinds of effects. The most likely scenario are endocrine disrupters in the form of any number of industrial chemicals introduced over the 20th and 21st centuries. The EPA has no protocols or rules for detecting if a new chemical is an endocrine disrupter. There are also no protocols for long-term mental effects. It's simply not tested for, there is no currently known ways of doing so and there are no laws requiring it anyway.
