A particular region of the brain responsible for sensing and processing speech and speech-like sounds is overly active in people with Parkinson’s disease, according to a new study. These findings may help provide a biological explanation for why Parkinson’s patients tend to speak more quietly than a given situation…

Reports of anxiety and other mental health issues are fewer in people with Parkinson’s who make greater use of a coping mechanism known as self-compassion, a U.K. study based on patients’ views found.

Researchers at Iowa State University are evaluating whether four months of group singing sessions can improve breathing and swallowing in people with Parkinson’s disease. Changes in brain activity and stress markers also will be analyzed. The study, supported by a three-year grant from the National Endowment for the Arts, is…

Parkinson’s patients have a subpopulation of astrocytes — brain cells that support neuronal function and health — that produce a vitamin D-activating enzyme called CYP27B1 and are involved in clearing the toxic alpha-synuclein clumps that form in the disease. The small study compared deceased Parkinson’s…

Women with Parkinson’s disease in China appear to have a poorer quality of life than do men, a study of patients at a Beijing rehabilitation center reported. Researchers observed that women experienced more physical discomfort, were more likely to perceive stigma, and expressed fewer positive emotions. When caring for…

Diagnosing Parkinson’s disease might be a matter of using artificial intelligence to “smell” patients’ skin, scientists in China reported. The artificial intelligence smell system they developed is detailed in study, “Artificial Intelligent Olfactory System for the Diagnosis of Parkinson’s Disease,” published in ACS Omega. No single test can…

Gastrointestinal (GI) dysmotility, or lack of movement, can impair the absorption and delay the effects of levodopa-based medication in people with Parkinson’s disease, a study reports. Notably, the study describes the cases of two Parkinson’s patients who stopped responding to levodopa/carbidopa intestinal gel — available under the brand name…

Treatment with an herbal preparation called Tongtian oral liquid, long used in traditional Chinese medicine, helped to prevent nervous system damage and normalize movement in a zebrafish model of Parkinson’s. Scientists in China reported these findings in the study, “Neuroprotective effects of Tongtian oral liquid, a…
