Some medicines are known for their adverse effects. It is also common knowledge that excessive use of medication is no good. A new study reveals now that calcium supplements can turn out to be more harmful that you might have initially thought: they may induce dementia to older women.
Dementia chooses weaker victims, and paired with calcium supplements, can install faster. The new study found that women who already suffered from other conditions and needed calcium supplements for their recovery were much more prone to developing dementia.
The study is based on analyses and research with cases of 700 elderly women (aged 70 or more) who had already had a stroke or blood flow disorders. The statistics show that stroke patients who use calcium supplements are exposed to the risk of developing dementia seven times more than a healthy person. With people with blood flow disorder, the chances are smaller: they are only two times more prone to the mental condition.
The study lasted for five years, because after the first investigations were made, five years later the same 700 women have been investigated again. The second tests showed that 54 of them were already diagnosed with dementia, although at the beginning of the study, none of them was related to mental diseases. The only sign at the beginning of the study was actually a cerebrovascular disease with those particular patients.
The study showed that out of 93 women who didn’t take calcium supplements after having a stroke only 12 of them developed dementia later. On the other hand, out of 15 women who did take them in the same conditions, six of them were diagnosed with the mental disease.
Nevertheless, researchers state that there is a clear difference between calcium supplements being the cause of dementia and a mere association between the two. More research needs to be done in order to establish the exact connection between them, as well as some precaution measures for women who use the supplements.
Dr. Kern declared for Live Science:
“The mechanism for the harmful effect of calcium supplementation is not fully understood.”
Dr. Marc Gordon (Zucker Hillside Hospital, New York) advises people that supplements are not always good for their health:
“People have a tendency to assume that dietary supplements are automatically innocuous, [but] high levels of supplementation as opposed to just dietary intake [of calcium] could conceivably have some deleterious effects.”
