ALSUntangled #77: Psilocybin.

ALSUntangled reviews alternate and off-label treatments prompted by patient interest. Here, we review psilocybin, a chemical derived from mushrooms and belonging in the category of drugs known as psychedelics. Psilocybin has plausible mechanisms for slowing ALS progression because of its ability to cross the blood brain barrier and effect neurogenesis and inflammation.

ALSUntangled #75: Portable neuromodulation stimulator therapy.

Spurred by patient interest, ALSUntangled herein examines the potential of the Portable Neuromodulation Stimulator (PoNS™) in treating amyotrophic lateral sclerosis (ALS). The PoNS™ device, FDA-approved for the treatment of gait deficits in adult patients with multiple sclerosis, utilizes translingual neurostimulation to stimulate trigeminal and facial nerves via the tongue, aiming to induce neuroplastic changes. While there are early, promising data for PoNS treatment to improve gait and balance in multiple sclerosis, stroke, and traumatic brain injury, no pre-clinical or clinical studies have been performed in ALS.

ALSUntangled #73: Lion's Mane.

Lion's Mane ( has historically been used as traditional medicine in Asia and Europe for its potential benefits in fighting infection and cancer. It has gained interest in the neurodegenerative disease field because of its mechanisms of action; these include anti-inflammation, neuroprotection, and promoting neurite growth demonstrated in various cell and animal models. A very small, double-blind, placebo-controlled trial in patients with mild cognitive impairment showed a temporary improvement in cognitive function; this finding has yet to be replicated.

ALSUntangled #72: Insulin.

ALSUntangled reviews alternative and off-label treatments for people living with amyotrophic lateral sclerosis (PALS). Here we review insulin, which has at least one plausible mechanism for slowing ALS progression. However, pre-clinical studies are limited and there have been no trials in PALS yet.

ALSUntangled # 69: astaxanthin.

ALSUntangled reviews alternative and off-label treatments for people living with amyotrophic lateral sclerosis (PALS). Here we review astaxanthin which has plausible mechanisms for slowing ALS progression including antioxidant, anti-inflammatory, and anti-apoptotic effects. While there are no ALS-specific pre-clinical studies, one verified "ALS reversal" occurred in a person using a combination of alternative therapies which included astaxanthin.

ALSUntangled #67: rituximab.

ALSUntangled reviews alternative and off-label treatments on behalf of people with ALS who ask about them. Here we review rituximab, a drug which specifically depletes B lymphocytes. We show a current lack of evidence for a role of these cells in ALS progression.

ALSUntangled #64: butyrates.

ALSUntangled reviews alternative and off-label treatments for people living with amyotrophic lateral sclerosis (PALS). Here we review butyrate and its different chemical forms (butyrates). Butyrates have plausible mechanisms for slowing ALS progression and positive pre-clinical studies.

Short- and long-term outcome and predictors in an international cohort of patients with neuro-COVID-19.

Background And Purpose: Despite the increasing number of reports on the spectrum of neurological manifestations of COVID-19 (neuro-COVID), few studies have assessed short- and long-term outcome of the disease.

Methods: This is a cohort study enrolling adult patients with neuro-COVID seen in neurological consultation. Data were collected prospectively or retrospectively in the European Academy of Neurology NEuro-covid ReGistrY ((ENERGY).

Reasons for delayed treatment initiation in Guillain-Barre syndrome.

Objective: The goal of this study was to analyze the reasons for delayed diagnosis of Guillain-Barre syndrome (GBS).

Methods: We retrospectively reviewed the records of all adult patients with GBS treated at Shamir Medical Center (SMC) from 2006 to 2018. We divided the patients into two groups: those with early initiation of treatment (within 24 h of arrival to ED), and those with later initiation of treatment (>24 h after arrival).

Estimating the X chromosome-mediated risk for developing Alzheimer's disease.

Parental lineage has been shown to increase the risk of Alzheimer's disease (AD) in the offspring, with greater risk attributed to maternal lineage. While 40 genes/loci have been linked to the risk of developing AD, none has been found on the X chromosome. We propose a new method to estimate the risk for developing AD mediated by the X chromosome in a subgroup of late-onset AD (LOAD) patients with amnestic mild cognitive impairment (aMCI) or early AD and unilateral ancestral history of AD or dementia, and pilot-test it on our clinic data.

Prior Stroke in PFO Patients Is Associated With Both PFO-Related and -Unrelated Factors.

To identify factors associated with prior stroke at presentation in patients with cryptogenic stroke (CS) and patent foramen ovale (PFO). We studied cross-sectional data from the International PFO Consortium Study (NCT00859885). Patients with first-ever stroke and those with prior stroke at baseline were analyzed for an association with PFO-related (right-to-left shunt at rest, atrial septal aneurysm, deep venous thrombosis, pulmonary embolism, and Valsalva maneuver) and PFO-unrelated factors (age, gender, BMI, hypertension, diabetes mellitus, hypercholesterolemia, smoking, migraine, coronary artery disease, aortic plaque).

Effects of a combined transcranial magnetic stimulation (TMS) and cognitive training intervention in patients with Alzheimer's disease.

Introduction: This clinical trial evaluates the efficacy and safety of a 6-week course of daily neuroAD™ therapy.

Methods: 131 subjects between 60 and 90 years old, unmedicated for Alzheimer's disease (AD), or on stable doses of an acetylcholinesterase inhibitor and/or memantine, with Mini-Mental State Examination scores between 18 and 26, clinical dementia rating scale scores of 1 or 2, enrolled for a prospective, randomized, double-blind, sham-controlled, multicenter clinical trial. Structural brain MRIs were obtained for transcranial magnetic stimulation targeting.

Theme 1 Epidemiology and informatics.

Identifying mechanisms of neurodegenerative disease causation has for long seemed to be beyond the pale of traditional epidemiological tools. Elucidating a plausible mechanism for initiation of amyotrophic lateral sclerosis (ALS) has appeared particularly elusive (1). The impression, that environmental risk factors for ALS were not providing consistent direction, meant there was no sturdy epidemiologically-based "handle" to grasp when trying to envisage a biological mechanism for triggering sporadic ALS (2).
