Neurodegeneration News and Research

RSS

Neurodegeneration is the umbrella term for the progressive loss of structure or function of neurons, including death of neurons.

Exposure to blue light may accelerate aging

A new study provides insights into the novel mechanisms through which blue light exposure interferes with non-retinal cell metabolic pathways in flies.

EPFL scientists uncover key mechanisms underlying the formation of protein tangles in the brain

Neurodegenerative disorders such as Alzheimer's and Parkinson's disease are associated with atypical proteins that form tangles in the brain, killing neurons.

Penn State receives $1.6 million grant to study the link between COVID-19 and cognitive decline

As populations around the globe age, dementia -; often caused by Alzheimer's disease and related disorders -; is a growing health issue for older adults worldwide.

UCL researchers identify multiple risk factors for a prematurely aging brain

By estimating people's brain age from MRI scans using machine learning, a team led by UCL researchers has identified multiple risk factors for a prematurely ageing brain.

Alzheimer's disease disrupts visual memory by degrading cross-hemispheric cells

A new MIT study finds that Alzheimer's disease disrupts at least one form of visual memory by degrading a newly identified circuit that connects the vision processing centers of each brain hemisphere.

GPNMB established as a risk gene and potential therapeutic target for Parkinson's disease

Computational, cell biological, and human tissue-based studies establish GPNMB as a risk gene and potential therapeutic target for Parkinson's Disease (PD), researchers report.

Nearly three-quarters of all stem cell lines are affected by DNA damage, say researchers

DNA damage caused by factors such as ultraviolet radiation affect nearly three-quarters of all stem cell lines derived from human skin cells, say Cambridge researchers, who argue that whole genome sequencing is essential for confirming if cell lines are usable.

Alzheimer’s disease is associated with characteristic gut metabolomic signatures

Scientists review current literature associated with the role of the gut-brain axis in AD pathogenesis.

Cognitive rehab may help older adults clear covid-related brain fog

Eight months after falling ill with covid-19, the 73-year-old woman couldn't remember what her husband had told her a few hours before. She would forget to remove laundry from the dryer at the end of the cycle. She would turn on the tap at a sink and walk away.

The aging human brain

Researchers describe alterations at the molecular and cellular levels that underly brain aging in otherwise healthy elderly adults.

Socioeconomic deprivation associated with increased dementia risk and faster memory decline

Socioeconomic deprivation, including neighborhood disadvantages and persistent low wages, are associated with higher dementia risk, lower cognitive performance and faster memory decline, according to several studies reported today at the Alzheimer’s Association International Conference 2022 in San Diego and virtually.

Study shows the link between common viruses and onset of Alzheimer’s disease

Alzheimer's disease can begin almost imperceptibly, often masquerading in the early months or years as forgetfulness that is common in older age. What causes the disease remains largely a mystery.

Damaging effects of blue light exposure worsen with age

The damaging effects of daily, lifelong exposure to the blue light emanating from phones, computers and household fixtures worsen as a person ages, new research by Oregon State University suggests.

Hollings researcher awarded grant to continue research into mechanisms behind medulloblastoma relapse

When MUSC Hollings Cancer Center researcher Jezabel R. Blanco, Ph.D., began studying neurosciences, first as a graduate student and later as a postdoctoral fellow, her research was focused on understanding the mechanisms underlying brain disease, both in the context of neurodegeneration and cancer, but mostly from a basic research angle.

Researchers find link between brain protein and increased vulnerability to neurodegeneration in epilepsy patients

A team of Florida State University College of Medicine researchers has found a link between a specific protein in the brain and increased vulnerability to neurodegeneration for individuals with temporal lobe epilepsy (TLE).

Wistar scientists reveal a novel ADAR1-SIRT1-p16INK4a axis in regulating cellular senescence

Aging and age-related disorders pose a complex challenge to the biomedical research community. To better understand how senescence is regulated is of high significance to promote healthy aging and treat age-associated disorders.

Study reveals a new molecular perspective to the cause of Gaucher's disease

A study by researchers at Baylor College of Medicine, the Jan and Dan Duncan Neurological Research Institute at Texas Children's Hospital and collaborating institutions is the first to associate neuronal activity to the levels of sphingolipids, a type of fat, in brain cells.

Lifestyle factors may be more important than age in determining a person's cognitive function

Individuals with no dementia risk factors, such as smoking, diabetes or hearing loss, have similar brain health as people who are 10 to 20 years younger than them, according to a new Baycrest study. The study found that a single dementia risk factor could reduce cognition by the equivalent of up to three years of aging.
