Neurodegeneration News and Research

RSS

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

Chlamydia pneumoniae found in the eye may aggravate Alzheimer’s disease

Chlamydia pneumoniae—a common bacterium that causes pneumonia and sinus infections—can linger in the eye and brain for years and may aggravate Alzheimer’s disease, according to a study from Cedars-Sinai.

Distinct tau chemical signatures redefine diagnosis across neurodegenerative diseases

Tau protein aggregation is a shared feature in over 20 neurodegenerative diseases (collectively referred to as "tauopathies"). New research led by Boston Children's Hospital challenges the current "one-size-fits-all" approach to diagnosing and treating these tauopathies.

Research uncovers why certain brain cells are more resilient to tau protein buildup

New research by UCLA Health and UC San Francisco has uncovered why certain brain cells are more resilient than others to the buildup of a toxic protein that is a hallmark of Alzheimer's disease and related dementias, potentially leading to new targets for therapies or treatments.

Lab-grown corticospinal neurons offer new models for ALS and spinal injuries

Researchers have developed a way to grow a highly specialized subset of brain nerve cells that are involved in motor neuron disease and damaged in spinal injuries.

New evidence shows Parkinson’s spreads via immune cells from the gut

New research reveals how Parkinson's spreads from the gut to the brain, with the help of immune cells – offering a new potential therapeutic strategy – in a study in mice led by scientists at the UK Dementia Research Institute at UCL (University College London).

Brain protein CUL5 protects neurons by clearing toxic tau clumps

Researchers at UC San Francisco have identified a hazardous waste collector in the brain that disposes of the toxic clumps of tau protein that can lead to dementia.

Overactive protein cleanup disrupts nuclear pores in neurodegenerative disease

When it comes to neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS) and certain forms of dementia, researchers have known that protein quality control and damage to the nuclear pore are key players.

Gut problems may shape Parkinson’s disease progression through the gut-brain axis

This narrative review examines how gastrointestinal dysfunction, gut dysbiosis, and altered gut-brain axis signaling are closely associated with the onset and progression of Parkinson’s disease. It synthesizes evidence supporting a possible bottom-up disease model while highlighting integrative, gut-targeted strategies as adjuncts to symptom management rather than proven disease-modifying therapies.

New research initiative aims to develop retinal screening tool for Alzheimer's

The human eye may literally become a window revealing the earliest signals of Alzheimer's disease, thanks to a new federally funded research initiative at Oregon Health & Science University.

New atlas of brain lysosomes sheds light on neurodegenerative disorders

Functioning brain cells need a functioning system for picking up the trash and sorting the recycling. But when the cellular sanitation machines responsible for those tasks, called lysosomes, break down or get overwhelmed, it can increase the risk of Alzheimer's, Parkinson's, and other neurological disorders.

Olive oil type matters for cognition and gut health in older adults

Higher intake of virgin and total olive oil was associated with modest but significant improvements in cognitive performance over two years in older adults with metabolic syndrome. These associations were partly linked to gut microbiota composition, with specific taxa such as Adlercreutzia contributing a small mediating effect.

Tiny plastic particles may interfere with brain processes implicated in Parkinson’s disease

Micro- and nanoplastics are increasingly detected in human tissues, including the brain, and experimental evidence suggests they can interact with biological pathways central to Parkinson’s disease pathology. This review synthesises mechanistic data indicating that plastic particles may influence protein aggregation, neuroinflammation, mitochondrial dysfunction, and the gut–brain axis, while emphasising the need for prospective human studies.

Unfolding the role of Hsp70 chaperones in neurodegeneration

Neurodegenerative diseases such as Alzheimer's, Parkinson's, Huntington's, and amyotrophic lateral sclerosis (ALS) affect millions of people worldwide, yet treatments remain largely limited to symptom management.

Shingles vaccination is linked to slower biological aging in older adults

This population-based study of U.S. adults aged 70 and older found that shingles vaccination was associated with slower epigenetic and transcriptomic aging, as well as lower systemic inflammation. No significant associations were observed for neurodegeneration or cardiovascular biomarkers, highlighting domain-specific molecular effects rather than broad clinical changes.

Rice’s SynthX Center leads interdisciplinary effort to tackle rare lymphatic disorders

Rice University's SynthX Center, directed by Han Xiao, has received an up to five-year, $18 million award from the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics and pHenotyping Technologies (LIGHT) program to develop innovative solutions for lymphatic diseases.

Researchers discover a biochemical route that plays role in Parkinson's disease

About 1 million Americans suffer from Parkinson's disease, with around 90,000 new cases diagnosed each year, according to the Parkinson's Foundation.

How "old RNA" reshapes sperm metabolism

Increasing paternal age has been linked to elevated health risks for the next generation, including higher risks of obesity and stillbirth. But what drives this increased risk remains unknown.

Shingles vaccination may slow biological aging in older adults

Shingles vaccination not only protects against the disease but may also contribute to slower biological aging in older adults, according to a new USC Leonard Davis School of Gerontology study.

Experts issue strong call for overhaul of UK dementia prevention strategy

A national panel of experts has issued the strongest call yet for the Department of Health and Social Care to overhaul how it approaches dementia prevention, pointing to vital evidence that dementia risk can be reduced and providing a framework for the development of new government policy that could improve brain health for millions.
