Did COVID-19-associated lockdowns increase the rate of memory decline in patients with cognitive impairments?

Researchers investigated whether COVID-19-associated lockdown measures had an impact on the cognitive decline rate.

Exploring the neuroprotective potential of cell-penetrating peptides, extracellular vesicles, and micro ribonucleic acids

In a recent review published in Biomedicines, researchers explored extracellular vesicles (EVs), cell-penetrating peptides (CPPs), and micro ribonucleic acids (miRNAs) as therapies for neurodegenerative diseases such as Alzheimer’s disease (AD) and Parkinson’s disease (PD).

Three intestinal bacteria associated with dementia with Lewy bodies discovered

Dementia with Lewy bodies (DLB), one of the most common forms of dementia, has no cure. Previous studies suggested that gut bacteria, the microorganisms that live in the human digestive tract, play a role in Parkinson's disease, another neurodegenerative disorder, but the bacteria involved in DLB had not been identified.

Tiny worm enables scientists to explore the theory that Parkinson's disease starts in the gut

A tiny worm called the C. elegans is enabling scientists to explore the emerging theory that Parkinson's disease starts in the gut.

Exploring two small molecules for the disintegration of alpha-synuclein fibrils

In a recent study published in the Proceedings of the National Academy of Sciences, researchers assessed the capability of two small molecules of disintegrating alpha-synuclein fibrils.

Changes in the cerebral neural network could function as a biomarker for neurocognitive disorders

In many neurodegenerative conditions, brain changes occur before symptoms emerge. But now, researchers from Japan have found a new way to distinguish these conditions in the early stages according to changes in brain activity patterns.

Characteristics of patients' drawing process can determine the type of dementia, study finds

The two most common neurodegenerative dementias are Alzheimer's disease (AD) and dementia with Lewy bodies (DLB). There is often an overlap of symptoms across these two diseases, which can make diagnoses difficult.

Decline in specific protein levels linked to Alzheimer’s disease, not buildup of amyloid plaques

New research from the University of Cincinnati bolsters a hypothesis that Alzheimer's disease is caused by a decline in levels of a specific protein, contrary to a prevailing theory that has been recently called into question.

The role of nasal microbiome in Parkinson's disease

A recent study provides an overview of how the nasal bacterial population influences olfactory processing and neurodegeneration.

Experts release appropriate use recommendations for Alzheimer’s disease blood biomarkers

Alzheimer’s disease blood biomarkers (BBMs) may revolutionize the diagnosis of Alzheimer’s in the future, but are not yet ready for widespread use, according to a newly-published article by leading international clinicians and researchers convened by the Alzheimer’s Association.

New chemical biological tools could help better understand the progression of Parkinson's disease

Researchers are a step closer to understanding how Parkinson's disease develops and progresses thanks to chemical biological tools developed at Simon Fraser University.

Research suggests a new pathway for developing Parkinson's disease

There is currently no cure for Parkinson's disease (PD), and one of the main difficulties for developing treatments is that we don't know exactly how or why the disease occurs.

4 Jul 2022

Key protein α-synuclein linked to inflammation and Parkinson's disease

Currently, there are no disease modifying therapies for Parkinson's disease that can change the progression of the disease. An international team of scientists led by faculty at the University of Colorado Anschutz Medical Campus is hoping to change that.

Antibiotic rifampicin attenuates C9orf72-linked dementia in genetically modified mice

What did Stephen Hawking and Mao Zedong have in common? They both suffered from Amyotrophic Lateral Sclerosis (ALS), a cure for which remains elusive. Scientists from Osaka Metropolitan University took an important step toward prevention of ALS and another brain disorder called Frontotemporal dementia (FTD) with their research on the effects of the antibiotic rifampicin on genetically modified mice.

Scientists gain important insights into novel mutation behind synucleinopathies

Parkinson's disease and Lewy body dementia belong to a family of neurodegenerative disorders called synucleinopathies because they are caused by the pathological accumulation of protein alpha-synuclein into structures called Lewy bodies and Lewy neurites in the brain.

Novel optobiological system may shine light on protein aggregation in Parkinson's disease

A novel system to control protein aggregation in a model of Parkinson's disease may answer longstanding questions about how the disease begins and spreads, according to a new study published March 9th in the open-access journal PLOS Biology by Abid Oueslati of Laval University, Quebec, Canada, and colleagues.

23 Mar 2022

Cell-hobbling fibrils found across diverse neurodegenerative diseases

Take a cell-deep tour of a brain afflicted with Alzheimer's disease, and you will find minuscule clumps of protein that seem suspicious. Ever since the 1980s, when neuroscientists began identifying these protein tangles, researchers have discovered that other brain diseases have their own tangled-protein signatures.

4 Mar 2022

Cell stress-related biochemical events may be partly driving Parkinson's disease

Parkinson's disease may be driven in part by cell stress-related biochemical events that disrupt a key cellular cleanup system, leading to the spread of harmful protein aggregates in the brain, according to a new study from scientists at Scripps Research.

23 Feb 2022

Combination of rifampicin and resveratrol helps stop dementia, finds study

Dementia is thought to occur when proteins called amyloid-β, tau, and α-synuclein accumulate in the brain and form oligomers. A research group from the Department of Translational Neuroscience, Osaka City University Graduate School of Medicine, had previously shown in a study using mice that the antibiotic rifampicin removes oligomers from the brain and improves cognitive function.

Study provides a new target for therapeutic intervention in Parkinson's disease

In an unexpected discovery, Georgetown University Medical Center researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease.
