Specific mRNA molecule may be useful as biomarker in ALS

A messenger RNA (mRNA) molecule that provides the instructions for a protein involved in glutamate signaling is not edited as efficiently in amyotrophic lateral sclerosis (ALS) patients as in people without the neurological disorder, according to a new study suggesting its potential use as an ALS biomarker. Glutamate is…

Gout medication decreases risk of ALS and other diseases: Study

Allopurinol and carvedilol, two medications respectively used to manage gout and high blood pressure, significantly reduce the chances of developing amyotrophic lateral sclerosis (ALS), Alzheimer’s, or Parkinson’s disease, a new study suggests. “These findings suggest a possible new direction for repurposing or developing medications for neuroprotection,” Brad…

Some sporadic ALS patients have mutation causing other diseases

A sizable portion of people with sporadic amyotrophic lateral sclerosis (ALS) carry a genetic mutation known to cause other neurological disorders, a new study shows. “This suggests shared risk factors among these diseases, shared mechanisms that cause nerves to die – and perhaps shared therapeutic strategies in the future,”…

Early clinical trial testing gut microbe transplants in ALS patients

An early clinical trial is testing whether fecal microbiota transplants (FMT) — a procedure that aims to introduce healthy bacteria to the digestive tract — might reduce inflammation among people with amyotrophic lateral sclerosis (ALS). “With this information, we could potentially provide new approaches for treatments by altering or…

AAN 2023: Radicava leads to better long-term survival in ALS

Radicava (edaravone) significantly prolongs long-term survival for people with amyotrophic lateral sclerosis (ALS), according to an analysis of nearly 3,000 patients. It didn’t significantly slow the progression of disease symptoms, as assessed by scores on the ALS Functional Rating Scale-Revised (ALSFRS-R), however. The results were presented at last…

AIT-101 clears toxic protein clumps, early data show

AI Therapeutics‘ experimental therapy AIT-101 led to reductions in levels of toxic proteins in people with amyotrophic lateral sclerosis (ALS) associated with mutations in the C9ORF72 gene, according to data from a clinical trial. The Phase 2a clinical trial also met its main goals of showing that AIT-101…
