People with Parkinson’s disease with symptoms affecting one side of the body, who were treated with focused ultrasound targeting the affected brain region, showed an improvement in motor features after four months, a small study reported. Side effects included involuntary movements, muscle weakness, speech problems,…
Later age at Parkinson’s disease onset is associated with high adherence to the MIND diet and benefits women more than three times as much as it does men, a study has shown. In contrast, adherence to the Greek Mediterranean diet significantly correlates…
A smartphone application designed to measure and monitor the walking mobility of people with Parkinson’s disease captured a 44% decrease in daily activities during the COVID-19 pandemic lockdowns, a study assessing the app reported. The lack of movement was due to confinement, not worsening disability, the…
Treatment with the antioxidant metal-alloy nanozyme reduced the build-up (aggregation) and transmission of disease-causing alpha-synuclein protein in the nerve cells and brains of a Parkinson’s disease mouse model, a study reported. Investigators believe these findings support further research to evaluate nanozymes as a Parkinson’s treatment.
Changes in how brainwaves synchronize, known to occur in people with Parkinson’s disease, originate from distinct nerve cell networks in multiple brain regions involved in motor control, a study found. Applying electrical stimulation to correct the abnormally coupled brainwaves may benefit…
Visual hallucinations in people with Parkinson’s disease are associated with a thinning of the inner layers of the eye’s retina, an exploratory study reported. Published in the journal Nature Scientific Reports, the study was titled “…
Production of the protein TOM20 rescued nerve cells that are damaged in people with Parkinson’s disease due to the toxic buildup of alpha-synuclein protein, a study in rats revealed. According to researchers, the interaction between TOM20 and alpha-synuclein represents a potential…
Scientists have created a tomato enriched in levodopa, or L-DOPA, a standard therapy for people with Parkinson’s disease. These tomatoes could represent a scalable, low-cost alternative L-DOPA source for Parkinson’s patients, particularly those in developing nations where treatment cost is prohibitive.
Using non-invasive, dry-electroencephalography (EEG) and machine-learning computer algorithms, researchers were able to distinguish between Parkinson’s disease patients with and without mild cognitive impairments with 80% accuracy, early results of a study found. Follow-up assessments will be…
Scientists have designed a so-called “organ-on-a-chip” device that can grow dopaminergic neurons — the brain cells most affected in people with Parkinson’s disease — in a 3D environment where they are more like real neurons in the brain, a study shows.
