Calcium is unique among metals because its ions have a very large concentration gradient across the plasma membrane of all cells, from 10 â3 M Ca 2+ outside, to 10 â7 M Ca 2+ inside.

Most people with relapsing-remitting MS -- about 80% -- eventually get secondary progressive MS. The relapses and remissions that used to come and go change into symptoms that steadily get worse. The shift typically begins 15 to 20 years after youâre first diagnosed with MS.tâs often harder to treat secondary progressive MS than relapsing-remitting MS. The main type of drugs for MS, called disease-modifying drugs (DMDs), make relapses happen less often and symptoms less severe. For people with SPMS who still have relapses, DMDs can still help.
