Gut bacteria affect brain health, mouse study shows
Gut bacteria can influence brain health, according to a study of mice genetically predisposed to develop Alzheimer’s-like brain damage. The study, by researchers at Washington University School of Medicine in St. Louis, indicates that gut bacteria produce compounds that influence the behavior of immune cells, including ones in the brain that can cause neurodegeneration. The findings suggest a new approach to treating Alzheimer’s and other neurodegenerative diseases.

There is currently no cure for the rare neurodegenerative disorder multiple system atrophy (MSA), and its rarity has made it difficult to understand how the disease progresses. Now a research team has created a successful mouse model of aggressive cerebellar-type…
Aerobic Exercise May Help More than Balance Training to Hold Off Symptoms of Cerebellar Ataxia
Currently, no medications exist to combat spinocerebellar ataxias, debilitating neurodegenerative diseases that cause loss of balance and coordination. Physicians recommend balance training to improve symptoms, but a new study suggests that rigorous aerobic exercise may provide greater benefit for adults…
ALS risk higher among production workers, those exposed to metals, volatile compounds on job
A new study finds people working in “production” – fields such as manufacturing, welding and chemical operation – who are exposed to hazardous chemicals on the job, may have increased risk of developing ALS. People with ALS report higher occupational exposure to metals, particulate matter, volatile organic compounds and combustion pollutants prior to diagnosis.

A new $9 million grant from Aligning Science Across Parkinson’s (ASAP) will enable advancement of UC San Diego’s discovery that inhibiting a single gene in mice converts other cell types directly into new neurons, alleviating all Parkinson’s symptoms.
Researchers link neurodegenerative disease protein to defective cholesterol metabolism
Researchers in Singapore have discovered that brain cells cannot maintain the cholesterol-rich myelin sheath that protects and insulates neurons in the absence of a protein called TDP-43. The study, which will be published August 4 in the Journal of Cell Biology (JCB), suggests that restoring cholesterol levels could be a new therapeutic approach for diseases associated with TDP-43, such as amyotrophic lateral sclerosis and frontotemporal dementia.
Spinal Fluid Biomarkers Detect Neurodegeneration, Alzheimer’s Disease in Living Patients
New research reveals that the same framework of proteins and peptides that can detect Alzheimer’s disease in cerebrospinal fluid can also detect other forms of neurodegeneration, like frontotemporal degeneration.

Rutgers Biomedical and Health Sciences has opened a new brain imaging research center to improve the diagnosis of neurological and psychiatric disorders and to help personalize and monitor treatments.
Deciphering Gene-Environment Interactions in Parkinson’s Disease
The interaction between an individual’s genetics and their local environment plays a critical role in an individual’s likelihood of getting Parkinson’s disease. In this perspective, researchers highlight how a common fly could be used to better understand the complex interactions…
New study finds low levels of a sugar metabolite associates with disability and neurodegeneration in multiple sclerosis
A new University of California, Irvine-led study finds low serum levels of the sugar N-acetylglucosamine (GlcNAc), is associated with progressive disability and neurodegeneration in multiple sclerosis (MS).
Researchers Identify Protein Produced After Stroke That Triggers Neurodegeneration
DALLAS – April 27, 2021 – Researchers with the Peter O’Donnell Jr. Brain Institute at UT Southwestern have identified a new protein implicated in cell death that provides a potential therapeutic target that could prevent or delay the progress of neurodegenerative diseases following a stroke.
Audacious projects develop imaging technology to aid eye tissue regeneration
As regenerative therapies for blinding diseases move closer to clinical trials, the National Eye Institute’s functional imaging consortium, a part of the NEI Audacious Goals Initiative (AGI), is pioneering noninvasive technologies to monitor the function of the retina’s light-sensing neurons and their connections to the brain.
Rotten Egg Gas Could Guard Against Alzheimer’s Disease
Typically characterized as poisonous, corrosive and smelling of rotten eggs, hydrogen sulfide’s reputation may soon get a face-lift thanks to Johns Hopkins Medicine researchers. In experiments in mice, researchers have shown the foul-smelling gas may help protect aging brain cells against Alzheimer’s disease. The discovery of the biochemical reactions that make this possible opens doors to the development of new drugs to combat neurodegenerative disease.

Researchers make significant step toward blood test for Alzheimer’s disease
Researchers at Washington University School of Medicine in St. Louis have developed a technique to detect minute amounts of a protein fragment linked to Alzheimer’s disease in the blood. The study, which will be published July 28 in the Journal of Experimental Medicine (JEM), shows that levels of p-tau-217 are elevated during the early stages of Alzheimer’s disease and could lead to a simple blood test capable of diagnosing the neurodegenerative disorder years before any symptoms begin to appear.
