NeuroString Sensor Measures Neurotransmitter Activity

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, “…

Synuclein Antibodies Not Useful Parkinson’s Biomarkers: 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…

Study: Resonance Tube Therapy Improves Speaking Ability

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,…

STING Protein Drives Inflammation and Neuronal Loss, Study Finds

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 …

Patterns of Brain Atrophy Line Up With Protein’s Damaging Spread

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…

Powerful MRI May Help Detect Apathy, Cognitive Problems

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 …
