Key Improvements to Parkinson's Disease Cell Therapies

Researchers have demonstrated that a transplant surgical procedure (called 'needle trauma') triggers a profound immune response and causes the death of most grafted dopamine neurons. They also found that co-transplantation of neuronal cell therapy with host regulatory T cells resulted in effective ...

Finding Rewrites Understanding Into Parkinson's Disease Pathway

Researchers have solved a long-standing mystery about how a protein helps rid the body of damaged mitochondria, in findings that could help lead to potential new treatments for Parkinson's ...

10 Pesticides Toxic to Neurons Involved in Parkinson's

Through a novel pairing of epidemiology and toxicity screening, researchers were able to identify 10 pesticides that were directly toxic to key ...

Chemical Exposure May Raise Your Risk for Parkinson's

Two years of heavy exposure to TCE, a liquid chemical that lingers in the air, water and soil, may increase the risk of Parkinson's disease by ...

Researchers have found that COVID-19 activates the same inflammatory response in the brain as Parkinson's disease. The discovery identified a potential future risk for neurodegenerative ...

Weight Change in Early Parkinson's May Be Tied to Changes in Thinking Skills

People who gain or lose weight soon after being diagnosed with Parkinson's disease may be more likely to have changes in their thinking skills than people who maintain their weight, according to ...

Voice Screening App Delivers Rapid Results for Parkinson's and Severe COVID

A new screening test app could help advance the early detection of Parkinson's disease and severe COVID-19, improving the management of these illnesses. Developed by a research team of engineers ...

Discovery Illuminates How Parkinson's Disease Spreads in the Brain

Aggregates of the protein alpha-synuclein spread in the brains of people with Parkinson's disease through a cellular waste-ejection process, suggests a new ...

Exercise Hormone Halts Parkinson's Disease Symptoms in Mouse Study

Researchers have shown that a hormone secreted into the blood during endurance, or aerobic, exercise reduces levels of a protein linked to Parkinson's disease and halts movement problems in ...

Researchers Uncover Where and Why Proteins Malfunction in Parkinson's Disease

Scientists have uncovered how a build-up of harmful protein starts to happen within neurons in Parkinson's disease, ultimately causing nerve cell death. By looking at how, where and why this ...

Inactivated Protein Complex Linked to Parkinson-Like Symptoms

Inactivation of a particular protein complex that plays a key role in keeping genes switched off leads to nerve cells not producing enough essential neurotransmitters. This could be part of the ...

Artificial Intelligence Model Can Detect Parkinson's from Breathing Patterns, Researchers Show

A device with the appearance of a Wi-Fi router uses a neural network to discern the presence and severity of one of the fastest-growing neurological diseases in the ...

Diagnosis of Early-Stage Parkinson's Disease Now Possible With New Method, Researchers Report

Cellular changes in Parkinson's could be revealed by adapting a related technique, known as quantitative MRI (qMRI). A new method enabled researchers to look at microstructures within the part ...

New Chemical Biological Tools to Monitor Parkinson's Disease

Researchers are a step closer to understanding how Parkinson's disease develops and progresses thanks to chemical biological ...

Parkinson's Disease: Copper Leads to Protein Aggregation, Study Finds

Copper exposure in the environment and the protein alpha-synuclein in the human brain could play an important role in the pathogenesis of Parkinson's disease. Researchers were able to show how ...

Three Distinct Brain Circuits in the Thalamus Contribute to Parkinson's Symptoms

Neuroscientists identified three circuits in the thalamus that influence the development of motor and nonmotor symptoms of Parkinson's disease. And by manipulating these circuits, they could ...

Older adults who start to experience bad dreams or nightmares could be exhibiting the earliest signs of Parkinson's disease, say ...

'Happy Hormone' Dopamine Plays Role in Identifying Emotions

Emotion-recognition among people with disorders such as Parkinson's disease or schizophrenia may be affected by changes in the levels dopamine in the brain, say ...

'Sting' Protein's Efforts to Clean Up Brain Cell Damage May Speed Parkinson's Disease Progress

In studies with mouse and human tissue, as well as live mice, researchers report that a snag in the normal process of cleaning up broken DNA in brain cells may hasten the progression of ...

Ultra-Powerful Brain Scanners Offer Hope for Treating Cognitive Symptoms in Parkinson's Disease

Ultra-powerful 7T MRI scanners could be used to help identify those patients with Parkinson's disease and similar conditions most likely to benefit from new treatments for previously-untreatable ...

Boost in Nerve-Growth Protein Helps Explain Why Running Supports Brain Health

Exercise increases levels of a chemical involved in brain cell growth, which bolsters the release of the 'feel good' hormone dopamine, a new study shows. Dopamine is known to play a key ...

Designer Neurons Offer New Hope for Treatment of Parkinson's Disease

Scientists describe a process for converting non-neuronal cells into functioning neurons able to take up residence in the brain, send out their fibrous branches across neural tissue, form synapses, ...
