I wouldn't group those together at all for the sake the argument. Take antidepressants for example. We're at the point of reexamining if we actually understand the consequences of long term usage of them. My personal experience was that my long term usage definitely came with issues and it's taken me a few years to feel like my emotional range has returned to a stabe baseline after going off them. I likely would have been better off using them short term. Depressiom is also quite similar to obesity in the sense that helping people develop the durable non-medical interventions while being treated with drugs would go further than just treating them with drugs alone.

Contrast this with Parkinson's which is a neurodegenerative disease with no known non-pharmacutical treatments and even the pharmacutical ones lose effectiveness as it progresses as they only treat symptoms, not the disease itself.
