Parkinson's disease

Scientists have identified a chemical produced by a common gut bacterium that travels to the brain and kills dopamine-producing neurons. Published in Nature Communications, the study establishes a direct link between a gut microbe and the development of Parkinson's-like symptoms.

Artificial intelligence detected subtle movement impairments linked to Parkinson's disease by analyzing simple videos. The system identified hidden signs in early-stage patients and at-risk individuals that were completely invisible to trained neurologists, offering a new tool for early detection.

A virus previously considered harmless may be affecting immune signaling in Parkinson’s disease. Researchers found human pegivirus in brain tissue of some patients, and its presence was linked to inflammation, altered gene expression, and more advanced signs of degeneration.

A new study shows that adjusting deep brain stimulation settings based on wearable sensor data and brain recordings can enhance walking in Parkinson’s disease. The personalized approach improved gait performance and revealed neural signatures linked to mobility gains.

A groundbreaking study suggests that Parkinson’s disease may begin in the kidneys, where a toxic protein builds up and travels to the brain. This discovery could reshape our understanding of the disease’s origins and risk factors.

A new study finds that people who consume more ultra-processed foods are significantly more likely to exhibit early warning signs of Parkinson’s disease, raising concerns about diet’s role in neurological health long before diagnosis.

Once considered little more than reversible brain lesions, deep brain stimulators can now fine-tune their output using brain activity as a guide. This adaptive method may revolutionize how doctors treat neurological and psychiatric disorders.

Psilocybin therapy produced surprising benefits in a small study of people with Parkinson’s disease. Beyond improving mood, the psychedelic treatment was linked to better motor function and cognitive performance.

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.
