A study published in Magnesium Research found that people with mild-to-moderate Alzheimer’s disease who had low levels of ionized magnesium had the most impaired cognitive function compared to a control group.
There are two way to test for magnesium levels. One is the one docs usually use which is serum total magnesium levels. This test did not show a deficiency. The deficiency did show up when the ion test was done.
The researchers said that magnesium deficiency overexcites the brain’s neurons which results in less coherence and reduced cognitive function. So…to make sure you have the right levels of magnesium, make sure to ask your doc to run the ion test.
