Before available treatments existed, children with the most common form of spinal muscular atrophy would would need a ventilator to breathe or die by the age of two. Now, several advancements have made SMA a treatable condition. While many states screen for it at birth, physicians and advocates say even more can be done to improve outcomes for SMA.
A new UCLA-led study has identified multiple new risk genes for Alzheimer’s disease and a rare, related brain disorder by using a combination of new testing methods allowing for mass screening of genetic variants in a single experiment.
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.
A study suggests that reducing tau protein in brain neurons will not protect against Parkinson’s disease and Lewy body dementias. If borne out, this result differs from Alzheimer’s disease, where reducing endogenous tau levels in brain neurons is protective for multiple models of the disease.
University of California, Irvine biologists have developed a new genetically engineered mouse model that, unlike its predecessors, is based on the most common form of Alzheimer’s disease. The advance holds promise for making new strides against the neurodegenerative disease as cases continue to soar.
A team of Case Western Reserve University researchers has found a way to measure key characteristics of proteins that bind to RNA in cells—a discovery that could improve our understanding of how gene function is disturbed in cancer, neurodegenerative disorders or infections.
A novel Alzheimer’s disease marker—coming early in progression of the condition—could open significant new fronts of research into possible therapies
A team of researchers at the Case Western Reserve University School of Medicine has taken a major step toward understanding the mechanisms involved in the formation of large clumps of tau protein, a hallmark of Alzheimer’s disease and several other neurodegenerative disorders.
Scientists at Sanford Burnham Prebys Medical Discovery Institute have created a drug that can lure stem cells to damaged tissue and improve treatment efficacy—a scientific first and major advance for the field of regenerative medicine. The discovery, published in the Proceedings of the National Academy of Sciences (PNAS), could improve current stem cell therapies designed to treat such neurological disorders as spinal cord injury, stroke, amyotrophic lateral sclerosis (ALS) and other neurodegenerative disorders; and expand their use to new conditions, such as heart disease or arthritis.
Researchers at Case Western Reserve University School of Medicine seek to optimize emerging methods of diagnosing two common neurodegenerative diseases—dementia with Lewy bodies and Parkinson’s disease dementia—which affect 1.4 million in the United States
GRAND RAPIDS, Mich. (Sept. 21, 2020) — A collaborative team between the University of Minnesota Medical School and Van Andel Institute (VAI) will soon begin a $6.2 million study that seeks to define the molecular linkages between aging and Parkinson’s disease — an approach for new treatment targets not yet explored by many researchers. The group recently earned a three-year grant from the Aligning Science Across Parkinson’s initiative, an international collaborative research effort partnering with The Michael J. Fox Foundation for Parkinson’s Research to implement its funding.
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.
Bristol scientists have discovered a novel pathology that occurs in several human neurodegenerative diseases, including Huntington’s disease.
The article, published in Brain Pathology, describes how SAFB1 expression occurs in both spinocerebellar ataxias and Huntington’s disease and may be a common marker of these conditions, which have a similar genetic background.
The long-running study on aging and brain health at the University of Kentucky’s Sanders-Brown Center on Aging Alzheimer’s Disease Center has once again resulted in important new findings – highlighting a complex and under-recognized form of dementia.
KINGSTON, R.I. – June 25, 2020 – Doug Sawyer was diagnosed with amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig’s disease, 11 years ago. His only muscles that still function are those that control eye movement.Despite his disability, Sawyer still works as an engineer from his home, designing electronics for Hayward Industries.
Even small changes may have big, long-term consequences. For amyloid beta peptides, a major hallmark of Alzheimer’s disease, a common chemical modification at a particular location on the molecule has a butterfly effect that leads to protein misfolding, aggregation and cellular toxicity.
In a new animal study examining Alzheimer’s disease, researchers found that disease progression could be slowed by decreasing neuroinflammation in the brain before memory problems and cognitive impairment were apparent.
Scientists at the UNC School of Medicine and colleagues created a new computational tool called H-MAGMA to study the genetic underpinnings of nine brain disorders, including the identification of new genes associated with each disorder.
Berkeley Lab scientists have made a surprising discovery that could help explain our risk for developing chronic diseases or cancers as we get older, and how our food decomposes over time.
Researchers at Albany Medical College in New York have discovered that a specific type of immune cell accumulates in older brains, and that activating these cells improves the memory of aged mice. The study, which will be published February 5 in the Journal of Experimental Medicine (JEM), suggests that targeting these cells might reduce age-related cognitive decline and combat aging-associated neurodegenerative disease in humans.
Evaluating the effectiveness of therapies for neurodegenerative diseases is often difficult because each patient’s progression is different. A new study shows artificial intelligence (AI) analysis of blood samples can predict and explain disease progression, which could one day help doctors choose more appropriate and effective treatments for patients.
GRAND RAPIDS, Mich. (Nov. 20, 2019) — A runaway, inflammatory immune response may be responsible for triggering severe depression during and after pregnancy, according to a new study published in the journal Brain, Behavior and Immunity.
