Antioxidant actions of ATH434 may help to slow Parkinson’s advance

ATH434, an experimental therapy that’s currently in clinical trials for a type of atypical parkinsonism known as multiple system atrophy (MSA), has antioxidant activities that may protect mitochondria and contribute to its therapeutic effects. Data supporting its actions were presented this month at the Society for Neuroscience in Washington,…

Compounds from marigold flowers show promise as treatment

Compounds extracted from marigold flowers may be useful in treating Parkinson’s disease, according to a study done in laboratory models. The study, “Active compounds from Calendula officinalis flowers act via PI3K and ERK signaling pathways to offer neuroprotective effects against Parkinson’s disease,” was published in Food…

Report: Addressing swallowing issues requires carer-clinician effort

Swallowing problems can cause deadly complications for people with Parkinson’s disease, if not handled appropriately, making it critical that hospital clinicians partner with caregivers to help address the needs of patients. That’s the argument made by Annie Brooks, director of strategic initiatives at the Parkinson’s Foundation, in “Dysphagia…

Lightweight gloves reported to ease tremor due to Parkinson’s

Scientists in Thailand have developed lightweight gloves that help to lessen the tremors affecting daily life for people with Parkinson’s disease. The gloves currently are available at King Chulalongkorn Memorial Hospital in Bangkok, but the researchers plan to partner with entrepreneurs to further refine the devices. One goal is…

Low oxygen may help to ease symptoms in Parkinson’s: Report

Exposure to low oxygen may help to ease the symptoms of Parkinson’s disease — but a lot more research is needed to conclusively determine the safety and effectiveness of this strategy for use among people with the neurodegenerative disorder, according to a new report. “From a clinical perspective, hypoxia…

Wrist-worn device shows good accuracy for measuring off time

The Parkinson KinetiGraph (PKG), a wrist-worn device resembling a watch, offers a moderate level of measurement for tracking symptom fluctuations and medication side effects in individuals with Parkinson’s disease. That’s according to the study “Application of single wrist-wearable accelerometry for objective motor diary assessment in…

Activating select estrogen receptor shows promise in lab models

Treatment with cianidanol, a plant molecule that can activate a specific estrogen receptor in the brain, showed neuroprotective potential in cell and animal models of Parkinson’s disease, a study reports. “The identification of cianidanol as a selective estrogen receptor beta agonist and evaluation of its neuroprotective…
