• The road ahead: 2020 January 5, 2020 Here at the SoPD, we are primarily interested in disease modification for Parkinson’s. While there is a great deal of interesting research exploring the causes of the condition, novel symptomatic therapies, and other aspects of Parkinson’s, my focus is generally on the science seeking to slow, stop or reverse the condition. At the start of each year, it is a…

• DBS: location, location, location December 15, 2019   Deep brain stimulation (or DBS) represents a well established treatment option for individuals with Parkinson’s who no longer respond to standard therapies. It involves tiny electrodes being embedded in the brain and they modulate populations of neurons that have become dysfunctional. The results of the DBS procedure can be “miraculous” for some individuals – reducing tremors and significantly improving…

• Is it time to back NAC? October 4, 2019   A lot of Parkinson’s research is focused on antioxidants – molecules that can reduce the level of stress a cell is under when it is not feeling well. One of the most widely discussed antioxidants on Parkinson’s online forums is a molecule called N–acetylcysteine (or NAC). Recently, the results of a small clinical trial – in which NAC was…

• Low-frequency Deep Brain Stimulation Reduces Freezing of Gait, Study Shows August 16, 2018 Low-frequency subthalamic deep brain stimulation (STN-DBS), but not high-frequency STN-DBS, reduces freezing of gait in Parkinson’s patients while preserving their ability to simultaneously process motor and cognitive information, a recent study shows. The study, “Decreasing subthalamic deep brain stimulation frequency reverses cognitive interference during gait initiation in Parkinson’s disease,” was published in the journal Clinical Neurosphysiology. Many Parkinson’s patients (50-70 percent) will…
• Not dead, dormant dopamine neurons?!? January 18, 2020   Every textbook written about the condition will tell you that the classical pathological characteristic of Parkinson’s is the loss of dopamine neurons in the midbrain region of the brain. It is the distinguishing feature that pathologists look for in order to provide a postmortem diagnosis of the condition. But what is meant by the words ‘loss of dopamine neurons’?…
• That time APOE met Alpha Syn February 10, 2020    Recently two independent research groups published scientific papers providing evidence that a genetic variation associated with Alzheimer’s may also be affecting the severity of pathology in Parkinson’s. The genetic variation associated with Alzheimer’s occurs in a gene (a functional region of DNA) called ApoE, and the Parkinson’s pathology involves the clustering of a protein called alpha synuclein. Specifically, both…
• Viva Las Vagus August 20, 2019   Increasing preclinical evidence is being presented that suggests the gastrointestinal system can play a role in models of Parkinson’s. In addition, there is mounting epidemiological data indicating that the gut can have some kind of influence in people with the condition. Recently, a new paper was published which explores the involvement of the vagus nerve. This is the bundle…

• Cognitive decline in Parkinson’s disease – is there anything we can do about it? March 5, 2019 For many people, one of the most concerning non-motor features of Parkinson’s disease (PD) is cognitive decline. Attention, working memory, executive function, memory, language and visual reasoning are the cognitive skills most frequently affected in PD which can be concerning because these skills allow us to perform daily functions such as paying attention, solving problems, remembering where items are and…
