Parkinson’s Patients Carrying Distinct Genetic Polymorphisms Less likely to Experience Levodopa–induced Dyskinesia, Study Shows

Parkinson’s patients carrying two types of genetic polymorphisms — a gene that has more than one variant in a given population — in the dopamine transporter gene are less likely to suffer from involuntary muscle movements associated with levodopa therapy, a study shows. The study, “DAT gene polymorphisms (rs28363170, rs393795)…

Deep Brain Stimulation is a Long-term, Effective, Safe Treatment for Parkinson’s, New Studies Show

Subthalamic deep brain stimulation (STN-DBS) seems to be a long-term, effective, and safe therapeutic option for patients with advanced Parkinson’s disease, new studies report. STN-DBS is a non-destructive surgical treatment for Parkinson’s, in which a battery-operated device that generates electrical impulses is implanted to specific regions of the…

Adding Physical Exercise to Parkinson’s Therapies Helps to Keep Patients Engaged and Active, Study Says

Physical exercise given in addition to standard treatment can improve overall quality of life in Parkinson’s patients, helping to ease physical limitations and allowing for greater engagement in daily activities, a review study suggests. The review, “The Effect of Physical Activity in Parkinson’s Disease: A Mini-Review,” was published in…

Therapies Targeting LRRK2 Gene Could Benefit Broad Population of Parkinson’s Patients, Study Finds

The LRRK2 gene may play an important role in nonhereditary Parkinson’s disease, not just the familial form as previously thought, researchers at the University of Pittsburgh School of Medicine​ have discovered. “This discovery is extremely consequential for Parkinson’s disease because it suggests that therapies currently being developed for a small…
