Lower-than-usual levels of the protein SIRT1 are evident in the blood of people with Parkinson’s disease, and correlate with greater disease severity and cognitive impairment, a study reported. A blood test of SIRT1 levels, for this reason, may serve as a biomarker…
Mutations in the PARK7 gene, known to cause early onset Parkinson’s disease, result in low levels of a protein called DJ-1 that is essential for nerve cell health, a study revealed. In fixing a protein processing malfunction in cells derived from members of…
Neupro patches placed on the shin caused significantly less skin irritation and itching in people with Parkinson’s’ disease who previously had site reactions when these transdermal patches were applied elsewhere, a new study has found. The patch’s effectiveness as a…
In a real-world clinical setting, Neupro Patches (rotigotine) eased the clinical signs and symptoms of Parkinson’s disease, with more than 70% of patients reporting mild improvement or better, including those 80 years and older, a real-world study shows. …
The number of people with early-stage Parkinson’s disease who reported sleep disturbances increased over the course of a five-year longitudinal study, with insomnia being the most common sleep problem among this patient population. The frequency of other sleep problems such as…
The natural compound kaempferol — which acts as a potent antioxidant — can reduce the physical and behavioral symptoms of Parkinson’s in a fruit fly model of the disease. According to the researchers, this molecule may exert its protective effects by…
Working-age adults with Parkinson’s disease who received deep brain stimulation (DBS) showed better social and occupational functioning than those who received the best medical therapies alone, a study has found. As such, the authors suggest, DBS could be prescribed to…
Researchers have developed a highly sensitive but low-cost method to detect dopamine, which may help in the early diagnosis of several disorders characterized by abnormal dopamine levels such as Parkinson’s disease, a study has found. For the first time, the new…
A direct causal link was found between two major underlying features of Parkinson’s disease — mitochondrial defects and lysosomal malfunction — in dopamine producing neurons that lacked the PARK2 gene, which is mutated in some cases of early-onset disease, a study discovered. …
With a single treatment, scientists were able to transform brain cells into functioning neurons that restored dopamine — the signaling molecule deficient in people with Parkinson’s disease — to normal levels, eliminating motor symptoms in a Parkinson’s mouse model. The results,…
