Zonisamide for Epilepsy May Ease Parkinson’s Motor Symptoms: Study

Zonisamide, an epilepsy medication approved in the U.S. for some seizure-causing disorders, may reduce the motor symptoms of Parkinson’s disease, according to a review study of clinical trial data. The findings also suggest the therapy is associated with improvements in daily life activities for Parkinson’s patients, and with reductions…

CBD Found to Improve Survival in Worm Models of Parkinson’s

Treatment with cannabidiol (CBD) prevented nerve cell death, extended survival, and reduced toxic protein clumps in nematode worm models of Parkinson’s disease, a new study reports. “These findings supported CBD as an anti-parkinsonian drug,” the researchers wrote, adding that “this CBD neuroprotective action might be due to its antioxidative…

Probiotic Supplements Found to Ease Parkinson’s Constipation in Trial

Probiotic supplements were found to ease multiple measures of constipation in people with Parkinson’s disease in a small clinical trial. According to researchers, the use of such supplements also “significantly” improved quality of life for patients with constipation problems. “In this study, multi-strain probiotics were used to treat [Parkinson’s]…

Dopamine Agonists Linked to Poorer Blood Vessel Function

Rates of blood vessel dysfunction are not significantly different in people with Parkinson’s disease compared to the general population, a small study reports. The findings indicate that, among people with Parkinson’s, smoking and the use of treatments called dopamine agonists are associated with poorer blood vessel function. The…
