Depression Linked to Absolutely Everything, Solutions Elusive. A newstudyis out today inJAMAasserting a link between type 2 diabetes and depression and vice-versa. The study now joins reams of studies in recent years–many of them by non-psychiatrists, just to be clear–that link depression with seemingly every human malady and shortcoming. Heart disease, cancer, obesity, chronic pain, racism, poverty, smoking and so on have all been tied in with depression, locked in the kind of bio-psychological feedback loop that has doctors calling for depression screening and the inevitable push for treatment with anti-depressants (which themselves have been linked with diabetes causation in some studies just to make things even more confusing) and me scratching my head over what it all means. Because it does all mean something. And maybe nothing all at once.
