The number of copies of mitochondrial DNA in the blood of people with Parkinson’s disease are not a biomarker of poorly functioning mitochondria — the source of energy that powers cells — but may instead reflect immune responses that occur outside the brain, a study found. The findings, which…
The first patient in a Phase 2 clinical study testing BIA 28-6156 — a small molecule in the pipeline at Bial for treating Parkinson’s disease in people with mutations in the GBA1 gene — has completed the full dose regimen, the company announced. The goal of the study,…
Actor Michael J. Fox has received the Presidential Medal of Freedom from U.S. President Joe Biden for his work as an advocate and founder of The Michael J. Fox Foundation for Parkinson’s Research. Awarded at the White House, the Presidential Medal of Freedom is the highest honor civilians can…
Men and women with Parkinson’s disease approach the decision to undergo deep brain stimulation (DBS) distinctively, according to a new U.S. study whose findings are now being used to develop support tools for patients in choosing or not choosing to have the surgery. For example, the study found that…
Weekly dance classes may help attenuate symptoms of depression in people with Parkinson’s disease, which results in changes in the brain toward better emotional control, a study from York University in Toronto suggests. “We’re not trying to cure Parkinson’s with dance,” Joseph DeSouza, PhD, who led the study, said…

Taking steps to increase patient education about osteoporosis — a bone-weakening condition that’s common in people with Parkinson’s disease — could potentially lower the risk of falls and encourage higher calcium intake for stronger bones among those with both conditions, a new study suggests. The researchers recommended distributing an…
A diet rich in antioxidants — such as vitamins A, C, E, and selenium and zinc — may help most older adults counter becoming frail, but its benefits are less certain for people with Parkinson’s disease, a study drawing on U.S. data suggests. Findings indicate that the disease’s complex…
Parkinson’s disease patients carrying the G2385R mutation in the LRRK2 gene, a known risk factor for the disease, show a slower worsening of tremors and less daytime sleepiness than those idiopathic Parkinson’s, whose disease has no identified cause, a study from China reports. The study also found that…
Neuron-supporting cells called astrocytes produce regular pulses of gamma-aminobutyric acid (GABA), a chemical that suppresses excessive brain activity, that appear to help maintain the body’s circadian rhythms and consistent sleep-wake cycles. That’s according to a study in mice. The findings, if confirmed in humans, may “help us to better understand…
