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,…

Pooling Imaging Data May Make Multi-center Clinical Trials Easier

Imaging data of brain inflammation in people with amyotrophic lateral sclerosis (ALS) that is obtained using different tracers and imaging equipment can be combined using a technique called the “pseudo reference region approach.” This finding may make it easier to conduct multi-center studies about ALS, according to a recent…

Target ALS Awards 4 Grants for Work Into Biomarker Discovery

Target ALS, a nonprofit working to advance research, has awarded a second round of grants supporting four projects that aim to discover and develop biomarkers for amyotrophic lateral sclerosis (ALS). The grants are part of The Target ALS Diagnosis Initiative, a $15 million comprehensive effort to discover…
