Wearable fingertip patch tracks Parkinson's medication levels through sweat

Engineers and neuroscientists at the University of California San Diego have developed a soft, wearable fingertip patch that continuously tracks a patient's Parkinson's disease medication levels through their sweat.

Bee venom boosts the effects of standard Parkinson's therapy

Parkinson's disease (PD) is a progressive neurodegenerative disorder caused by the loss of dopamine-producing neurons, leading to motor symptoms such as tremors, rigidity, slowed movement, and impaired balance, as well as cognitive decline.

New drug candidate improves Parkinson's treatment in animal models

For many people with Parkinson's disease, the body stops moving the way it used to. A hand may tremble at rest. Muscles may stiffen.

New peptide strategy may protect brain cells involved in Parkinson's disease

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered a new strategy that may protect neurons and other brain cells involved in Parkinson's disease in the future.

New study identifies dopamine's role in reversing Alzheimer's

Imagine if patients with Alzheimer's could have their memories restored. Such a future may seem like a pipe dream, but a new study by researchers at Tohoku University, in collaboration with the University of California, Irvine, has identified dopamine dysfunction as a previously unrecognized mechanism underlying memory impairment, unlocking a potential therapeutic means of reversing cognitive decline.

Can supplements slow Parkinson’s disease? Review reveals where the evidence stands

Dietary supplements are widely used by people with Parkinson’s disease, but this review finds that none have yet been proven to slow disease progression. Biotics, nicotinamide riboside, and omega-3 fatty acids combined with vitamin E show the most promise, but larger, longer, and better-designed trials are needed.

Antibodies targeting GPNMB may slow Parkinson's disease progression

Monoclonal antibodies can block a key immune‑related protein that drives the spread of brain cell damage in Parkinson's disease (PD).

Gut microbiome clues may help spot Parkinson’s disease in its earliest phase

Researchers found that a Parkinson’s disease-related gut microbiome pattern appears not only in people with diagnosed Parkinson’s, but also in some non-manifesting GBA1 variant carriers and a subset of healthy individuals. The findings suggest that gut microbiome changes may help flag people who are closer to Parkinson’s disease development, although longitudinal studies are still needed to confirm predictive value.

Scientists turn plastic waste into Parkinson’s drug levodopa using engineered bacteria

Researchers engineered a two-strain microbial system that converts PET-derived terephthalic acid into levodopa, overcoming key bottlenecks in transport and enzyme inhibition. The proof-of-concept process achieves high yields under mild conditions and demonstrates a potential route for upcycling plastic waste into valuable pharmaceuticals.

Misdiagnosed Parkinson's patient regains life after NPH treatment

At age 66, Richard "Dick" Nash first suspected something might be wrong when he participated in a Dallas walk for juvenile diabetes in honor of his granddaughter.

Gut problems may shape Parkinson’s disease progression through the gut-brain axis

This narrative review examines how gastrointestinal dysfunction, gut dysbiosis, and altered gut-brain axis signaling are closely associated with the onset and progression of Parkinson’s disease. It synthesizes evidence supporting a possible bottom-up disease model while highlighting integrative, gut-targeted strategies as adjuncts to symptom management rather than proven disease-modifying therapies.

Parkinson’s disease may stem from iron starvation rather than iron overload

This perspective argues that Parkinson’s disease may involve functional iron deficiency, where bioavailable iron is limited despite normal or elevated total iron in the brain. The authors propose that iron sequestration, not iron toxicity alone, may impair dopamine synthesis and neuronal survival.

Rethinking dopamine’s role in movement and Parkinson’s disease

A McGill-led study is challenging a popular theory about how dopamine drives movement, a discovery that could shift how scientists think about Parkinson's disease treatments.

Combining stem cell therapy and BDNF enhancement to manage Parkinson’s disease

Parkinson's disease (PD) is an age-related, progressive, neurodegenerative condition, caused by loss of dopamine-producing neurons.

Driving simulator exposes early Parkinson’s impairments that routine tests fail to detect

A high-fidelity driving simulator detected subtle visuospatial, attentional, and reaction time impairments in people with mild to moderate Parkinson’s disease, even when standard cognitive tests appeared normal. The study shows that simulator-based assessments can uncover real-world driving difficulties linked to disease severity that traditional screening tools often miss.

Sensory effects of flavanols trigger physiological responses in the brain

Astringency is a dry, puckering, rough, or sandpapery sensation in the mouth caused by plant-derived polyphenols.

Machine learning detects early rising behavioral changes in mouse models of Parkinson’s disease

Detecting early rising Parkinson's disease (PD) symptoms could improve treatment outcomes by enabling earlier treatment interventions.

Weekly injectable drug offers hope for Parkinson's patients

A new weekly injectable drug could transform the lives of more than eight million people living with Parkinson's disease, potentially replacing the need for multiple daily tablets.

Study finds fewer H. pylori infections among Parkinson’s patients

A large case-control study from China found that people with Parkinson’s disease were significantly less likely to test positive for Helicobacter pylori infection compared to controls. The findings suggest a potential protective link between this common stomach bacterium and Parkinson’s disease, though causality remains unproven.

iPS cell transplants show early promise for treating Parkinson's disease safely

In a first-of-its-kind human trial, researchers transplanted iPS-cell-derived dopaminergic progenitors into patients with Parkinson’s disease and observed promising motor improvements with no serious safety concerns over 24 months. The therapy showed increased dopamine synthesis without tumor formation or graft-induced dyskinesia.
