I am seeking more information about the problem of Calcium deposits building up in the brain, after long term use of Calcium suppliment drugs, used for increasing a persons bone density in deseases such as Osteoporosis. I heard of a Geriatrician who noted that several patients who had an "unusual" form of Dimentia, and who had died, after autopsey, showed large amounts of Calcium deposits in the brain. All their histories showed they had been on long-term calcium suppliments. I guess the theory is that the body excretes any 'unused' calcium and therefore there is no danger. But what happens in a case where the "norm." does not happen? Where is this extra calcium stored in the body? Can anyone point me in the direction of research done on this subject. I don't want to be a party-pooper, but the medical profession often tend to be a bit blase regarding the unknown dangers with some of the drugs we take.
