A soft, stretchable sensor called NeuroString could be used for measuring the activity of neurotransmitters — chemical messengers that nerve cells use to communicate — in the bodies of living animals. The novel sensor, which may have potential in Parkinson’s disease research, was described in the study, “…
Levels of antibodies against synuclein proteins are lower in people with Parkinson’s disease than in heathy individuals, but these antibody levels cannot be used to distinguish Parkinson’s from other neurological disorders, a new study suggests. “Considering the degree of variation within the levels of all synuclein [antibodies] in controls…
Voice therapy using resonance tubes — glass cylinders partially submerged in water — improved loudness and other vocal parameters in people with Parkinson’s disease, according to results of a small clinical trial from Brazil. “Resonance tube voice therapy has positive effects on the vocal aspects in individuals with” Parkinson’s,…
Men who have distressing dreams more than once a week are at more than two times higher risk of being diagnosed with Parkinson’s disease, a new study suggests. “This study provides evidence for the first time that frequent distressing dreams in community-dwelling older adults, may be associated with an…
Using a personalized “virtual brain” could help in determining the optimal configuration of deep brain stimulation for people with Parkinson’s disease and other neurological disorders, a study suggests. “We offer a computational model that holds the potential to be easily translated towards the individual patient level and used as…
A blood test that assesses how the activity of a group of enzymes, called P450s, changes when they are blocked could be useful for diagnosing Parkinson’s disease in early stages, according to a new study. “Effective diagnostic systems and biomarkers for patients without subjective motor symptoms have not yet been…
A protein called STING, which normally helps sense infectious threats like viruses, may help to drive the inflammation that spurs neurodegeneration in Parkinson’s disease, according to a study in mouse and cell models. The study, “STING mediates neurodegeneration and neuroinflammation in nigrostriatal α-synucleinopathy,” was published in …
In people with Parkinson’s disease, patterns of brain atrophy over time are consistent with patterns of alpha-synuclein spreading through the brain, an imaging study in patients suggests. The study, “Regional changes of brain structure during progression of idiopathic Parkinson’s disease – A longitudinal study using deformation…
Deterioration in a small brain region called the locus coeruleus is associated with worse apathy and cognitive problems among people with Parkinson’s disease, according to a new study. The study, “Locus Coeruleus Integrity from 7 T MRI Relates to Apathy and Cognition in Parkinsonian Disorders,” was published in …
Curcumin, an antioxidant naturally found in turmeric, was well tolerated by participants in a small Parkinson’s disease clinical trial. However, trial results did not show evidence that taking curcumin improved quality of life or eased symptoms for Parkinson’s patients. “Our study failed to show that curcumin can improve the…
