Childhood Form of ALS Identified, Linked to SPLTC1 Mutations

A previously unknown form of amyotrophic lateral sclerosis (ALS) — one with onset during childhood — is caused by mutations that alter the production of certain lipids (fat molecules), scientists report. “We found that a genetic form of the disease can also threaten children. Our results show for the first…

MediciNova Secures European Patent for MN-166 Plus Riluzole

The European Patent Office will grant MediciNova a patent that covers the combination of MN-166 (ibudilast) and riluzole for the treatment of amyotrophic lateral sclerosis (ALS), MediciNova announced. The patent, once issued, will cover a wide range of doses and dosing regimens for both medications, and it…

3D Imaging System May Have Applications in ALS Research

A novel system for three-dimensional (3D) imaging of zebrafish may be useful for studying the motor and neuronal deficits linked with amyotrophic lateral sclerosis (ALS), a study suggests. The system was described in the journal Optica, in the study “Coded-aperture broadband light field imaging using…

Stretchable Electronics May Allow Wearable Sensors to Diagnose ALS

Stretchable electronics that are “intrinsically” stretchable — meaning they have tissue-like mechanical properties that integrate sensory devices with human skin — can better detect signals from a patient’s body than current, more rigid sensors, a study suggests. For now, its researchers are looking into a design for these electronics as a…

Imaging Technique Measures Mitochondrial Abnormalities in ALS

An imaging technique, called 31-phosphorus magnetic resonance spectroscopy (MRS), can be used to assess mitochondrial abnormalities in people with amyotrophic lateral sclerosis (ALS), a new study demonstrates. This non-invasive procedure could be useful for evaluating potential ALS treatments, researchers suggested. The study, “Magnetic resonance spectroscopy…

TDP-43 Protein Abnormalities in ALS Linked to DNA Damage

Abnormalities in the activity of the protein TDP-43, whose gene is often mutated in amyotrophic lateral sclerosis (ALS), can increase DNA damage in cells, a study shows. These findings shed light on the molecular underpinnings of ALS, and may open new avenues for treatment, its researchers said. The study,…

Melatonin Might Benefit ALS Patients, But More Research Needed

People with amyotrophic lateral sclerosis (ALS) who use melatonin have better survival outcomes and experience slower disease progression, a new analysis indicates. The findings suggest that melatonin may be beneficial for people with ALS. However, because the analysis was not designed to find cause-and-effect relationships, further studies are needed,…
