I can't speak for depression, but I was suffering from muscle spasms and tremors last year (both external and internal). Magnesium was suggested, I now take two a day and they have almost entirely dissipated. It certainly wouldn't surprise me that the presence or lack of such substances could have significant effects upon the brain too though I have noticed no changes in that regard.
