Alchemical Musings has written a sharp (as a tooth and nail) account of some pretty troubling directions in biological psychiatry, which is moving toward the territory of prevention.
As he notes:
Instinctively, preventative health care seems like a good thing. Western medicine is often criticized for primarily responding to acute crises, instead of proactively promoting health and well-being. However, the reductionist flattening of minds into brains leads to categorical errors which pervert the Hippocratic principle to “do no harm”. Applying the medical paradigm of treating risks (instead of disorders) to mental conditions stretches the dangerously elastic diagnostic net beyond the breaking point.
