Although common, delirium often goes undocumented in the medical records of many Parkinson’s patients who experience the symptoms, results from a new study show, and those who have been diagnosed with delirium often lack instructions for future care. The study, “Documentation and Diagnosis of Delirium in Parkinson’s…

A novel method that involves looking for disease-associated alpha-synuclein inside of neuron-derived extracellular vesicles — packets of cellular cargo that are released by nerve cells in the brain, and can be isolated in a person’s blood — may help to diagnose and monitor the progression of Parkinson’s disease. A…

ABBV-951, AbbVie‘s experimental under-the-skin formulation of levodopa/carbidopa, was generally well-tolerated and increased average “on” time by more than three hours among people with Parkinson’s disease. Those results from a Phase 3 open-label clinical trial were shared at the 8th European Academy of Neurology (EAN) Congress in Vienna, Austria, in…

Among people with Parkinson’s disease, lower levels of a bacterial compound called butyrate in the gut are associated with more severe depression, a new study indicates. Results also revealed that altered butyrate levels in Parkinson’s patients are associated with epigenetic changes in these individuals’ cells. The study, “…

Among people with Parkinson’s undergoing deep brain stimulation (DBS), those who receive stimulation in a certain brain region — the medial and ventral subthalmic nucleus — are more likely to develop a distressing side effect known as mania, a yearlong study in more than 100 DBS patients reported.

Analyses that estimate the length of a person’s vocal tract, which involves controlling muscles used in speech, could help to identify Parkinson’s disease, according to a new study. “The standard clinical method for classifying parkinsonian voice is by perceptual evaluation, which however is subjective,” the researchers wrote. “Computerized voice analysis…

Inbrija, an approved treatment for “off” episodes of Parkinson’s disease, has now been launched in Germany. The medication is being sold in Germany by Esteve Pharmaceuticals under an agreement with its developer Acorda Therapeutics. In exchange for supply of the product, Acorda will receive a significant…

Two European pharma companies have teamed up to create a technology platform that will help people with Parkinson’s disease find the best time to take their medication and make personalized adjustments to their treatment schedules. Gerresheimer AG is partnering with Finnish MedTech start-up Adamant Health Oy on new…

StrivePD, a Rune Labs‘ app that collects motor symptom data for people with Parkinson’s disease via measurements recorded by an Apple Watch, has been cleared for use by the U.S. Food and Drug Administration (FDA). “When people with Parkinson’s are prescribed new medications, adjusting how much to take and…

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, “…
