Light therapy has not yet been convincingly shown to help people with ALS. However, at specific wavelengths and energy densities, LT appears safe and has theoretically plausible mechanisms. There is a single case report suggesting benefits for light therapy in ALS, but it contains in sufficient detail to independently confirm diagnosis or treatment benefit. Further studies are needed to determine whether LT is useful for people with ALS, and via what specific protocols.
Mechanistic plausibility
Anti-fungals
It is unknown if fungi exist in the brain of PALS. If they do exist, it is unknown if they have any pathogenic effect, and unknown if antifungal drugs would modify ALS disease progression. There are no pre-clinical ALS model studies, verified ALS cases, or ALS clinical trials to suggest that antifungals would be of any significant benefit to PALS, and these medications can cause harm. At this time, we strongly discourage PALS from taking antifungal drugs for their ALS disease. We hope in the future that independent laboratories will look for fungi in the CNS of PALS using more appropriate experimental methods.

Penicillin G/Hydrocortisone
In our opinion, there is no convincing evidence that GABA overload plays a role in ALS progression. PNG/HC has other theoretical mechanisms by which it could slow ALS progression, but previous human trials involving steroids and a trial of a b lactam with more potent effects on glutamate did not help. We have not been able to confirm the diagnoses, nor the improvements described in the case series of 3 PALS taking PNG/HC; however, even if these treatment effects were real, these improvements were transient and quickly became unresponsive to treatment. Unless the ongoing placebo-controlled trial shows objective and sustained clinical improvements, we do not recommend that PALS take this expensive and risky combination of penicillin G and hydrocortisone.

Antiretrovirals
Antiretrovirals are a group of diverse drugs developed for HIV infections that vary widely in theoretical efficacy against HERVs, side effect profiles, and cost. HERV expression is apparently increased in some PALS; however, it is unknown if this is a
beneficial, neutral, or pathological process. Furthermore, it is not clear if ARV-targeted mechanisms such as cell infection and viral replication are taking place in PALS. Based on the lack of evidence for use of ARVs in PALS who test negative for HIV and HTLV, we cannot recommend them as a treatment for ALS. We look forward to the results of the two ongoing trials of ARVs in PALS.

Copper
Copper dysregulation may play a role in ALS progression, particularly for the form caused by SOD1 mutations. Given the complexity of this problem, simple copper supplements are unlikely to be useful to PALS with normal serum copper levels. We do not recommend using these. CuATSM, on the other hand, has more promising potential mechanisms of action, and several positive pre-clinical studies in mutant SOD1 ALS models. There are even a small number of PALS reporting benefits from it, though in our opinion the described benefits are thus far of uncertain clinical significance. At this time, the safety of repeated doses of CuATSM is unknown, as is the optimum daily dose, and it appears to be very expensive. Until trials clarify dosing and safety, as well as effectiveness in patients with and without SOD1 mutations, we do not recommend using CuATSM for ALS.

Basis
Basis has mechanisms of action that could theoretically be useful in treating ALS. It appeared reasonably safe in a small, short duration study of healthy volunteers and it is fairly inexpensive. However, we found no data in preclinical ALS models, no case reports, and no trials in PALS. Based on this lack of data, ALSUntangled cannot currently recommend use of Basis to slow, stop, or reverse the progression of ALS.

Eric is Winning
In conclusion, we find few plausible mechanisms by which components of the EIW regimen might impact ALS progression, and no pre-clinical or clinical evidence to support using this complicated, expensive and potentially risky treatment. Mr. Edney appears to have had very slow ALS progression even before he started his protocol, and there is no convincing evidence that the EIW regimen slowed, stopped or reversed his disease.

Acuscope
Acuscope appears reasonably safe, but it is not clear that it has a mechanism of action that would be useful to PALS. One person with PLS experienced slightly slower ALSFRS-R measurements while using Acuscope than she did before starting it, but a PALS had slightly faster ALSFRS-R progression during treatment. Since the natural history of motor neuron disease progression can vary spontaneously, it is not clear that either of these slight changes in progression were related to the treatment. Given these limitations, at this time we cannot endorse the use of Acuscope to slow, stop or reverse ALS progression.
