Hi, jroc:
I don't know about the link I provided, but calcium deficiency has been implicated in depression (and also calcium over consumption).
Years of suffering with AS have left my bones quite weak from demineralization and this is due, as were my kidney stones, to a lack of calcium. It is, however, easy for me to believe that some group did not find serum calcium low--because in AS this is usually HIGH--while it is in the process of being expelled from our bones!
I usually have some good contrary data to cite, but for now I will suggest this is my own opinion, for what it is worth: Calcium deficiency is rampant amongst those of us with AS and there are over 200 diseases related to the calcium problem and I have had some, but precious scant feedback from members successfully treating depression with calcium supplementation; I would agree that it is probably not that easy and inflammation plays a role but it is related probably through OPGL (OsteoProteGerin Ligand).
HEALTH,
John
