Could a Common Virus Help Drive Parkinson’s?

New research suggests a previously harmless virus may be linked to Parkinson’s disease. Scientists detected Human Pegivirus (HPgV) in the brains and spinal fluid of Parkinson’s patients but not in controls, challenging assumptions that the virus is benign.

Overactive Neurons May Drive Parkinson’s Cell Death

A new study shows that overactivation of dopamine-producing neurons in the brain can trigger their degeneration, mirroring what happens in Parkinson’s disease. Using a mouse model, researchers found that chronic activation disrupted daily activity patterns, damaged neuronal axons, and eventually killed cells in the substantia nigra.

Reshaping Nuclear Speckles Could Halt Alzheimer’s

A groundbreaking study reveals that reshaping nuclear speckles — tiny structures inside cell nuclei that regulate protein maintenance — could be a novel way to treat proteinopathies like Alzheimer’s, Parkinson’s, and prion diseases. Researchers found that pyrvinium pamoate, an existing FDA-approved drug, alters the surface tension of nuclear speckles, making them less round and more effective at supporting proteostasis.

Cycling Boosts Brain Function in Parkinson’s Disease

A new study reveals that long-term adaptive cycling can measurably reshape brain signals in people with Parkinson’s Disease, offering clues into how exercise relieves motor symptoms. Researchers used deep brain stimulation (DBS) implants to track neural activity before and after 12 sessions of dynamic cycling.

Dogs Can Sniff Out Parkinson’s Disease

Trained detection dogs can identify Parkinson’s disease (PD) with remarkable accuracy by sniffing skin swabs, according to a new study. In double-blind trials, the dogs achieved up to 80% sensitivity and 98% specificity, even when samples came from patients with other health conditions.

Side of Parkinson’s Onset Shapes Cognitive and Emotional Decline

Parkinson’s disease often starts on one side of the body, and new research shows this asymmetry influences how non-motor symptoms progress. Patients whose symptoms begin on the right side tend to experience greater cognitive decline and higher dementia risk.

Cough Medicine Shows Promise in Slowing Parkinson’s Dementia

A clinical trial has revealed that Ambroxol, a common cough medicine in Europe, may help slow cognitive decline in people with Parkinson’s disease dementia. The 12-month study found that the drug stabilized psychiatric symptoms, protected against brain damage, and even improved cognition in genetically at-risk participants.

PET Imaging Maps Brain Inflammation in Progressive Speech Disorder

A novel PET imaging study has identified unique patterns of neuroinflammation in patients with progressive apraxia of speech (PAOS), a rare disorder that impairs the brain’s ability to plan speech. Using TSPO PET scans, researchers found elevated inflammation in brain regions involved in movement and speech, particularly in patients who also showed signs of Parkinson-plus syndromes.

Ear Wax Reveals Parkinson’s Disease Biomarkers

A novel screening method for Parkinson’s disease (PD) analyzes the volatile compounds in ear wax to detect early signs of the condition. Researchers found that four specific volatile organic compounds (VOCs) are significantly different in people with PD.

Oral-Gut Bacteria Linked to Dementia Risk in Parkinson’s Disease

A new study has found that bacteria from the mouth may migrate to the gut and contribute to cognitive decline in people with Parkinson’s disease. Researchers identified harmful microbes and their toxins in the gut of Parkinson’s patients with dementia, suggesting a possible link between oral hygiene, gut health, and neurodegeneration.

Link Found Between Autism and Early-Onset Parkinson’s Risk

A large-scale Swedish study has found that individuals with autism are at significantly higher risk of developing early-onset Parkinson’s disease. Researchers followed over two million people and discovered that those with autism were four times more likely to develop the neurodegenerative condition before age 50.

Exercise Boosts Stem Cell Therapy for Parkinson’s

Exercise enhances the effectiveness of stem cell-derived neuron transplants in a Parkinson’s disease (PD) rat model. Transplanted neurons alone improved basic motor functions, but when combined with voluntary exercise, the rats displayed significantly better agility and paw control.
