Like many couples, Joe and Linda Lacroix of Milton, Vermont, spent much of their lives working, raising families, maintaining their home, and planning for the future. Unlike most, however, there was always a dark cloud looming on their horizon — a gene for Huntington’s disease carried by Joe’s mother.

Skin cells from people with amyotrophic lateral sclerosis (ALS) have altered metabolisms and increased levels of a type of cellular stress called oxidative stress, a new study shows. This may indicate new treatment targets for ALS. The study, “ALS skin fibroblasts reveal oxidative stress and ERK1/2-mediated…

A machine learning algorithm has shown that depression and a perceived lower quality of life are significant predictors of high caregiver burden among those who care for patients with amyotrophic lateral sclerosis (ALS), a study has found. The study, “Prediction of caregiver burden in amyotrophic lateral sclerosis:…

There are differences in the way the fluid around the brain and spinal cord moves in people with amyotrophic lateral sclerosis (ALS), and understanding these could have implications for the development of future therapies, a study suggests. The study, “Non-invasive MRI quantification of cerebrospinal fluid dynamics…

The European Medicines Agency (EMA) granted orphan drug status to Cytokinetics‘ reldesemtiv for the treatment of amyotrophic lateral sclerosis (ALS), the company announced. The move follows fast track designation granted in December by the U.S. Food and Drug Administration for the same indication, and provides the…

A zebrafish model that reproduces key amyotrophic lateral sclerosis (ALS) symptoms and characteristics, including protein clumping, when exposed to blue light could aid in understanding disease mechanisms and in developing new treatments. The model was described in the study, “Optogenetic modulation of TDP-43 oligomerization accelerates ALS-related…

The Medidata Institute and Project ALS have announced a research partnership aimed at better understanding amyotrophic lateral sclerosis (ALS) and developing new and personalized treatment approaches. With a focus on rare diseases, the institute works with scientists, regulatory agencies, patient advocates, life science companies, and research…

Astrocytes — cells of the nervous system cell that provide support to neurons — were seen to help protect motor neurons from damage caused by toxic protein clumps in a cell model of amyotrophic lateral sclerosis (ALS). The study reporting this finding, “Distinct responses of neurons…

Factors like head trauma or fracture, electric shock, playing some competitive sports, drinking water from private wells, use of herbicides for gardening, and taking specific dietary supplements all may be associated with the development of amyotrophic lateral sclerosis (ALS), according to a new study. However, larger studies are required…

A neurotoxic amino acid called β-N-methylamino-L-alanine (BMAA) fed to vervet monkeys caused damage to the spinal cord similar to what is seen in amyotrophic lateral sclerosis (ALS), potentially making them a much-needed new animal model for research, a study reported. Adding L-serine, a non-toxic amino acid, to their diet…
