- The results of our examinations and the results out of literature suggest that Minocycline could also have an effect on neuro-degenerative diseases and particularly have an effect with MSA. In the USA a study already examining the impact of orally given Minocycline to patients with Chorea Huntington or amyotrophic lateral sclerosis is taking place. The National Institutes of Health (NIH) in the USA will perform a multicentre, double-blind study about the effect of Minocycline on Parkinson’s Disease (NIH website, www.nih.gov).
