Mysterious circular RNA linked to Alzheimer’s & Parkinson’s disease

Posted on September 21, 2023 by Paul McClure

Researchers have identified a link between circular RNAs and neurodegenerative diseases

Researchers have gained new insights into largely overlooked circular RNAs in brain cells and the crucial role they play in diseases like Alzheimer’s and Parkinson’s. In addition to providing valuable information about the molecular mechanisms underlying these conditions, their findings open the door to developing diagnostic tests and treatments for them.

Simple test predicts Alzheimer’s risk, 20 years before symptoms show

Researcher Shankar Dutt with a new diagnostic tool that can isolate proteins from other biomolecules in the blood to search for signs of early neurodegeneration

Australian National University (ANU) physicists have combined nanotechnology, artificial intelligence and molecular biology to design a novel method that looks for Alzheimer’s disease protein markers in blood. These markers are tell-tale signs of early neurodegeneration, and early detection is so far the best defense we have in order to effectively intervene in Alzheimer’s progression. While there’s no cure for the disease, a 20-year jump on symptoms first appearing has the potential to significantly change health outcomes.

Study reveals how mutated protein invades the brain in Parkinson’s

Posted on September 8, 2023 by Paul McClure

Researchers have discovered how Parkinson's disease-causing proteins spread in the brain

A new study has revealed how the mutated proteins that are a hallmark of Parkinson’s disease spread and aggregate in the brain. The finding opens the door to developing a way of halting the disease’s progression and may be useful in tackling other neurodegenerative diseases caused by protein aggregation.

Four gut disorders associated with increased Parkinson’s risk

Posted on August 28, 2023 by Paul McClure

A study has found that four gut disorders are associated with an increased risk of developing Parkinson's disease

A new study has found that particular gastrointestinal disorders are associated with an increased risk of developing Parkinson’s disease. The research provides further evidence to support the hypothesis that the neurodegenerative disorder begins in the gut.

Retina scans may be able to reveal more than just the state of your vision

For the first time, scientists have identified a marker in the retina that may lead to the development of Parkinson’s disease, and it may be detected years prior to diagnosis.

Step in the right direction: App helps Parkinson’s sufferers walk better

Posted on August 7, 2023 by Paul McClure

A new app helps people with Parkinson's disease re-train their walking to improve their gait and reduce the likelihood of falling

For people with Parkinson’s disease, the simple act of walking can require constant mental vigilance to maintain balance and avoid falling, which is exhausting. Researchers have now developed a free smartphone app that helps people with Parkinson’s improve their gait and coordination and reduce the likelihood of falls, all while providing important exercise.

Grow-your-own stem cells may repair Parkinson’s damage

Posted on July 24, 2023 by Bronwyn Thompson

Parkinson's disease patients may one day use their own cells to regrow neurons

A new stem cell therapy for Parkinson’s disease is one step closer to human trials after scientists were able to successfully rebuild neural damage in an animal model.

Parkinson’s discovery opens door to new targeted therapies

Posted on July 20, 2023 by Bronwyn Thompson

Scientists have uncovered a cellular mechanism that could help treat familial Parkinson's disease

Around a million Americans are living with Parkinson’s disease, the neurological condition that greatly, and most often progressively, affects the dopamine-producing powerhouse area of the brain, the substantia nigra. While there is no cure, medication is generally aimed at substituting or boosting dopamine, which can help lessen the movement-impairment that comes with the debilitating disease.

“Unconventional” mechanism underlying Parkinson’s disease discovered

Posted on June 27, 2023 by Paul McClure

Researchers have discovered the mechanism by which the protein optineurin creates 'garbage bags' (green) around damaged mitochondria (red), marking them for removal

We may be one step closer to developing a treatment for Parkinson’s disease, thanks to new Australian research that has discovered how a protein called optineurin works in a distinct way to clear damaged mitochondria from the brain.
