I think they should first stop treating depression as a single illness. There are likely thousands different reasons for brain to end up with similar symptoms. Many forms of nutritional deficiencies likely turn into something that can be symptomatically classified as depression and sometimes be fully reversible by just restocking that missing nutrient or reducing its intake. Yet we clinically classify such conditions the same as ones caused by some brain injury or mentally horrible experiences that rewire brain circuits in weird ways.
