Treating Mitochondrial Disease/Dysfunction in Autism

Image
In my book I will be covering the science behind hopefully almost all autism, which then naturally leads to translating it into therapy.  In the ideal world you would just skip straight to the therapy and the final section of the book will be just that.  Clearly it would make sense to read the science first, so that you know what are the dysfunctions that you might need to treat. Hopefully there will also be some case studies from people who have applied a science-based approach to identify and implement effective therapies. Roger would clearly make a very good example of a reversible in-born metabolic-caused type of autism. I will be posting on my blog some drafts from the Part III - Translating Science to Treat Autism.  This is of course just one person's collection of other people's ideas and some of his one.  The reader and his/her medical medical team ultimately decide what to implement and must monitor its ongoing implementation.  * * *...

Nitrosative Stress, Nitric Oxide and Peroxynitrite

Image
In this example of Brain Injury, developing oligodendrocytes are injured and killed by substances released from activated microglia , including nitric oxide and superoxide, which form peroxynitrite. Peroxynitrite has been found to kill these cells through the activation of the 12-lipoxygenase pathway for metabolizing arachidonic acid. Mitochondria may be involved in this pathway as a source of reactive oxygen species. Much has been written in this blog about oxidative stress, which has now been extremely well researched in autism and more generally. Let’s recap oxidative stress. The most knowledgeable researcher in this area is Abha Chauhan.   Based on her research and that of others we now know a great deal.   Recall that the body’s key antioxidant is called glutathione (GSH) and when it neutralizes a free radical GSH is converted to its oxidized form, glutathione disulfide (GSSG).   A good measure of oxidative stress is the ratio of  GSH/GSSG. ·    ...
