A study involving MS patients with secondary progressive multiple sclerosis was conducted at the Oregon Health and Science University. People who took lipoic acid had less brain atrophy. There was less brain tissue loss with people who used lipoic acid compared to a control group. The results were promising enough that phase 2 studies are being conducted regarding the safety and efficacy of lipoic acid.
This study caught my eye because I use alpha lipoic acid because it is good for skin. I wonder if the alpha lipoic acid that I have been taking for years was one of the many factors that sent my primary progressive multiple sclerosis into remission. I also take DMAE for skin, but know of no studies regarding its effect on MS.
I think many healthy practices can combine to help MS patients. For example, it is recommended that people drink 8 glasses of water per day (this is especially true in Arizona where I live). You can see the many healthy practices I used at https://www.amazon.com/Multiple-Sclerosis-Mission-Remission-Healing-ebook/dp/B07D7JBZ5L/ref=mp_s_a_1_2?ie=UTF8&qid=1529367853&sr=8-2&pi=AC_SX236_SY340_FMwebp_QL65&keywords=multiple+sclerosis+Mission+remission
