Parkinson's disease

Dancing can significantly reduce depression in Parkinson's disease, a new study suggests. Not only did participants report feeling better, but brain scans also showed decreased activity in a key area linked to emotional regulation.

A study found that levodopa-induced dyskinesia disconnects the motor cortex from movement control, allowing abnormal movements. Ketamine reduced these movements, restored some brain control, and altered neural interactions, showing promise as a potential treatment.

Consuming unsweetened caffeinated coffee is linked to a lower risk of Alzheimer’s, Parkinson’s, and related mortality, while sweetened or artificially sweetened coffee showed no such benefits.

Parkinson’s patients were observed to consume less hydrogenated oils and more non-hydrogenated oils, olive oil, and mayonnaise.

Recent research identified hundreds of genetic variants influencing brain structure sizes, linking larger volumes to Parkinson’s risk and smaller volumes to ADHD.

Researchers found that reducing the activity of a protein called Drp1 helps protect brain cells in Parkinson’s disease by restoring mitochondrial function and cleaning up toxic proteins, offering potential new treatments for the condition.

A new study finds that adaptive deep brain stimulation, which adjusts in real time to brain activity, reduces Parkinson’s symptoms by 50%, offering more personalized treatment and fewer side effects compared to traditional stimulation methods.

Researchers found that blocking a protein called Activin A can prevent dyskinesia, a debilitating side effect of Parkinson's treatment, potentially allowing patients to stay on levodopa longer without developing uncontrollable movements.

Researchers developed a model using blood proteins and clinical data to predict Parkinson's disease risk up to 15 years before symptoms appear. This early detection could help prevent or delay the progression of the disease.

Researchers at the University of Florida developed an AI-powered video-processing system that analyzes hand movement tests to detect subtle changes in Parkinson’s disease symptoms, enabling more precise and accessible monitoring of disease progression from home.

A recent study has uncovered a significant link between the brain chemical dopamine and our ability to understand and attribute mental states to ourselves and others.

Visual hallucinations in Parkinson’s disease are linked to significant cholinergic deficiencies in the left ventral visual stream and left superior temporal lobe, highlighting potential targets for treatment.

Older adults with new-onset anxiety are more than twice as likely to develop Parkinson's disease, suggesting anxiety could be an early indicator for the neurodegenerative disorder.

Researchers found that dopamine is crucial for social cognition, including understanding emotions and mental states. Dopamine imbalances, as seen in disorders like Parkinson's, directly cause social difficulties, suggesting potential for dopamine-based treatments to improve social skills.

Scientists have discovered how a key enzyme, PINK1, is switched on by interacting with specific parts of cell machinery, which helps protect brain cells from Parkinson's disease.
