Ambroxol, a common cough medicine, may help stabilize neuropsychiatric symptoms in Parkinson’s disease dementia (PDD) and shows cognitive promise for patients with mutations in the GBA1 gene, according to results from a Phase 2 clinical trial. While ambroxol is widely used in Europe to treat respiratory conditions, it’s not approved…

People in the prodromal, or presymptomatic, stage of Parkinson’s disease show increased immune activity, with T cells targeting the proteins PINK1 and alpha-synuclein at levels similar to those seen in patients already diagnosed with the neurodegenerative condition, a new study reports. These two proteins — PINK1 and alpha-synuclein —…

Copper supplementation that reaches the brain reduces the signs and symptoms of Parkinson’s disease in a mouse model, a study found. Researchers found that copper restored the function of SOD1, an antioxidant enzyme that’s prone to misfolding and forming toxic clumps, impairing the function of dopamine-producing nerve cells that…

Blocking the inflammatory protein ASC with IC 100, ZyVersa Therapeutics’ experimental therapy to reduce inflammation, prevented the activation of the inflammasome in microglia — the brain’s resident immune cells — and the start and perpetuation of an inflammatory response. That’s according to results from a study announced by the…

Inflammation visible in brain scans of people in the early stages of Parkinson’s disease may serve as an early indicator of dementia risk and offer a promising target for interventions aimed at preventing cognitive decline, a study suggests. “[O]ur findings suggest that significant … neuroinflammation in early [Parkinson’s] might…

A newly developed test was able to distinguish — with an accuracy of 95% — between individuals with and without Parkinson’s disease, using samples of cerebrospinal fluid (CSF), the liquid surrounding the brain and spinal cord, according to a new study from Germany. The researchers noted that Parkinson’s often…

A new artificial intelligence (AI) tool may help predict the structure of amyloid fibrils, that is, misfolded protein fibers that accumulate in the brain of people with neurodegenerative diseases such as Parkinson’s. Called Ribbonfold, the tool is designed to address the complex and variable structures of misfolded proteins by…

Nearly 1 in 8 people diagnosed with Parkinson’s disease in Finland within the past couple of decades were later given a different diagnosis, usually within two years, underscoring the need for better clinical criteria and regular checkups. When Parkinson’s and dementia with Lewy bodies, a neurodegenerative disease also…

Nitrase Therapeutics’ NDC-0524, an antibody therapy for Parkinson’s disease, significantly reduced alpha-synuclein aggregation and spreading in mouse models of the disease, according to preclinical data released by the company. The antibody targets nitrated alpha-synuclein, a misfolded form of the protein that forms toxic clumps in dopaminergic neurons, the nerve cells…

A new collaborative effort between Mayo Clinical Laboratories and Amprion will expand access to the diagnostic company’s SAAmplify–αSYN test — designed to detect the presence of abnormal alpha-synuclein protein in people suspected of having neurodegenerative diseases — across the U.S., according to a joint press release.
