I have an idea, as Trump immigration policy, separated children from their families; now can any one see, the mentall illnessess associated with that parental separtion; how many children develop these kind of illnesses assoiciated with child hood traumas. This could be done by long term study consisting of many years following these children to their adulthood. Results might influence creating some barriers, to such policies that might result in a huge burden of diseases, and its long term impact on mental well being of future generation. Those who are interested in such kind of study and their context allows can take initiative. What are your ideas. please share with us!
