Genetic variants of the NEK1 gene that cause the coded protein to lose its function seem to increase the odds of developing amyotrophic lateral sclerosis (ALS) by more than ninefold, with these patients significantly more likely to experience weakness in their hands as a first symptom, a study has…

A cancer treatment called tamoxifen, which previously showed promise in preclinical studies for the treatment of amyotrophic lateral sclerosis (ALS), provides only modest and short-lasting benefits to patients with the disease, a small Phase 1/2 clinical trial has found. According to the study’s researchers, larger studies and longer…

The teeth of people with amyotrophic lateral sclerosis (ALS) show their bodies metabolize metals — from chromium to zinc — in abnormal ways starting in infancy, and these changes predispose them to ALS disease as adults. The study, which looked at how metal uptake early in life can affect…

The Phase 2 clinical trial investigating Clene Nanomedicine‘s CNM-Au8 as a potentially disease-modifying therapy for people with amyotrophic lateral sclerosis (ALS) has enrolled more than half of its participants ahead of schedule. RESCUE-ALS (NCT04098406) dosed its first participant in January,…

The U.S. Food and Drug Administration (FDA) has given fast track designation to Orphazyme’s investigational therapy arimoclomol for the treatment of amyotrophic lateral sclerosis (ALS). A therapy candidate is put on the FDA’s fast…

Levels of creatinine kinase — a marker of muscle damage — are elevated in most amyotrophic lateral sclerosis (ALS) patients and appear to be significantly higher among those whose disease progresses at a slower pace, a study in patients and mice shows. These findings suggest that this protein, whose rise…

Changing the composition of bacteria in the gut using antibiotics or fecal transplants may help prevent or reduce the severity of symptoms of amyotrophic lateral sclerosis (ALS), a study in mice with the most common ALS mutation shows. This gut-brain connection may help explain why some patients with this…

The clear, colorless liquid that fills and surrounds the brain and spinal cord may spread toxic protein aggregates from one nerve cell to others among people with amyotrophic lateral sclerosis (ALS), a study in mice suggests. When repeatedly infused with the cerebrospinal fluid (CSF) from ALS patients, animals…

Exposure to a neurotoxic molecule produced by blue-green algae seems to raise a person’s odds of developing amyotrophic lateral sclerosis (ALS), particularly for those under 65, a population-based study from Italy shows. The research examined individuals who lived close to freshwater systems — a river, lake, even a…

Rare variations in the TET2 gene seem to double a person’s risk of multiple neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), frontotemporal dementia (FTD), and Alzheimer’s disease, according to a recent study. This gene codes for a protein involved in removing small chemical groups from DNA…
