Increased body mass and sedentary behavior do not increase the risk of having Parkinson’s disease, a study shows. To date it is still not fully understood what causes Parkinson’s disease, but several environmental and lifestyle factors have been suggested as contributors to this disease. In the study, “Body mass…
Non-motor symptoms (NMS) in Parkinson’s disease are significantly more frequent and differ between men and women, a new study shows. The study, “Frequency of non-motor symptoms in Parkinson’s disease presenting to tertiary care centre in Pakistan: an observational, cross-sectional study,” was published in the journal BMJ Open.
Brain training reduces the severity and duration of freezing of gait and improves cognition and daytime sleepiness in Parkinson’s patients, a study shows. The study, “Cognitive training for freezing of gait in Parkinson’s disease: a randomized controlled trial,” appeared in the journal npj Parkinson’s Disease.
The findings of a Harvard University study are furthering understanding of the mechanisms involved in movement disorders and may open new therapeutic opportunities to treat Parkinson’s disease. The mouse study, “The Striatum Organizes 3D Behavior via Moment-to-Moment Action Selection,” was published in the journal Cell. The brain relies…
Microglial cells in the brain play an essential protective role against prion diseases, a new study shows. The findings could have implications for diseases characterized by protein aggregation, such as Parkinson’s and Alzheimer’s. The study, “Microglia are critical in host defense against prion disease,” was published…
Early sleep-related and autonomic symptoms — related to automatic or involuntary body functions — are associated with an increased risk of future psychotic symptoms in Parkinson’s disease patients, according to a recent study. These symptoms are also associated with a reduction of specific nerve cells in a region of the brain…
Parkinson’s disease is linked to impaired response of eyes to blue light, a finding that may provide new insights into the mechanisms involved in non-motor symptoms of the disease. The study, “Melanopsin-mediated pupil function is impaired in Parkinson’s disease,” was published in the journal Scientific Reports. Parkinson’s…
The inability to remember proper sequences of information, such as numbers or events, occurs before cognitive impairment in Parkinson’s patients who have mild motor symptoms, a Chinese study shows. The research “Impaired serial ordering in nondemented patients with mild Parkinson’s disease,” was published in the journal PLOS ONE.
Microorganisms living in the gut can influence the progression of neurodegenerative diseases through two types of brain cells, and understanding more about how they suppress inflammation could lead to new therapies for diseases such as multiple sclerosis (MS) and Parkinson’s, a study found. The research, “Microglial control…
A gene called Ankrd16 can prevent the harmful protein aggregates that build up in neurological disorders, including Parkinson’s disease, according to researchers. Their study, “ANKRD16 prevents neuron loss caused by an editing-defective tRNA synthetase,” published in the journal Nature, adds a new layer of knowledge about the underlying…
