ALSUntangled™ reviews alternative and off label treatments (AOTs), with the goal of helping people with ALS make more informed decisions about them.
MitoQ has a promising mechanism, positive preclinical data from two different ALS models, and appears reasonably safe and inexpensive, especially at doses of 10 mg daily. Available anecdotal data are insufficient to determine how helpful this might be in PALS. A small open-label pilot trial with validated ALS diagnoses and outcomes appears warranted.

Acupuncture is reasonably safe, and has potential mechanisms of action, pre-clinical studies and case reports suggesting that it could be a useful treatment for ALS. However, before it can be endorsed even as a candidate for a phase II trial, the studies described above need to be independently replicated using more clearly verified diagnoses and more rigorous designs, including appropriate controls and validated ALS outcome measures.
There is rapidly expanding evidence implicating alterations in the fecal microbiome in wide-ranging human diseases, including potential contributions via a gut-brain signaling axis in neurodegenerative and neuroimmunologic disorders. Proposed mechanisms such as immune modulation and the production of neurotoxins by clostridia or other microbiota could bypass an intact blood-brain barrier. To date, there are no data directly implicating the fecal microbiome in ALS, nor published case reports of FMT being tried in PALS. Data in other neurodegenerative and neuroimmunologic disorders are largely circumstantial, comprising a handful of published case reports. Therefore, ALSUntangled does not recommend FMT as a treatment for ALS at this time. However, it is plausible that the fecal microbiome plays a role in some neurologic disorders, including ALS. Given the lack of effective therapies and the relatively low cost and low risk of FMT – if performed by experienced clinical centers we support further investigations in this developing field. A reasonable next step would be a detailed molecular analysis of gut bacteria in ALS patients; certainly, these are the types of studies being advocated by the NIH Human Microbiome Project. If alterations are detected in the gut microbiome of ALS patients, a following step would be properly controlled studies in animal models, such as ALS mice. These studies could employ the same germ-free, and/or probiotic treatment regimens published in mouse models of EAE, Alzheimer’s disease, and obesity.
Mitochondrial dysfunction, glutamate excitotoxicity, and oxidative stress have all been implicated in ALS pathogenesis, and targeting these mechanisms individually or by a cocktail such as the Deanna Protocol could play a role in future ALS therapies. However, many of the preclinical and animal studies related to these pathways have not translated into successful treatments in patients with ALS. While there are anecdotal reports of improvements in patients with ALS on the Deanna Protocol, there is no convincing objective evidence of benefit yet. Thus, at this time, ALSUntangled does not recommend the Deanna Protocol to patients with ALS.
Before it can be recommended, a reproducible version of the Deanna Protocol should be shown to influence plausible physiologic mechanisms such as central nervous system ketone bodies, as well as clinically meaningful outcome measures such as ALSFRS-R and FVC in patients with ALS.
