Neither a patient’s sex nor the degree of disease progression substantially affects the manifestations of sleep disturbances in Parkinson’s disease, a study reports. More research into this “very common” and life-affecting problem — and into other non-motor symptoms — of Parkinson’s is needed, its researchers said. The study,…

Visual dysfunction and its underlying brain changes can identify Parkinson’s disease patients at higher risk of cognitive decline, who might benefit most from future clinical trials, according to two new studies. The studies, “Organisational and neuromodulatory underpinnings of structural-functional connectivity decoupling in patients with Parkinson’s disease”…
A branch of the National Institutes of Health has awarded a $3.1 million, multiyear grant to a research team to study changes in speech, and look at movement, in Parkinson’s patients given bilateral deep brain stimulation (DBS). The grant from the National Institute on Deafness and other Communication Disorders (NIDCD) was…
Ten weeks of lockdown to prevent the spread of COVID-19 in Italy led to a worsening of cognitive, behavioral, and motor symptoms in people with Parkinson’s disease, particularly those with mild cognitive impairment, a study shows. These findings add to previous reports linking COVID-19-related confinement to significantly…
People with schizophrenia spectrum disorder have an increased risk of developing Parkinson’s disease later in life, according to both regional and nationwide data from Finland. This higher risk may be associated with medication-induced changes in the brain’s dopamine system — also affected in Parkinson’s patients — or disease-associated mechanisms, and…
Dormant viruses lying hidden in the nervous system can give rise to Parkinson’s disease, according to a newly-published biological model. The article describing this finding, “How microcompetition with latent viruses can cause α synuclein aggregation, mitochondrial dysfunction, and eventually Parkinson’s disease,” was published in the Journal…
Medtronic has launched a clinical trial to assess the safety and efficacy of adaptive deep brain stimulation, or aDBS, an investigational feature of its Percept PC Neurostimulator device, in people with Parkinson’s disease. Unlike conventional continuous deep brain stimulation, known as cDBS — in which electrical signals…
With north of 150,000 followers on his TikTok account, elite athlete Jimmy Choi knows his way around social media. After all, the ultra marathoner has competed on four seasons of the popular TV series “American Ninja Warrior.” He’s also had Parkinson’s disease (PD) since 2003. Still, nothing prepared…
The levels of a specific RNA molecule that provides instructions to make the alpha-synuclein protein may help, at an early stage, to distinguish patients with Parkinson’s disease from those with dementia with Lewy bodies, a study has found. Researchers said these results highlight the importance of exploring the potential…
An extract from three plant species reduced signs of motor disturbances in rodent models of Parkinson’s disease and lessened the associated molecular defects of the cellular recycling process known as autophagy, a study showed. Further research is needed to confirm that…
