Parkinson’s Disease Tremor Explained by Reflex Loop Changes

Parkinson’s disease tremor explained by reflex loop changes

Many Parkinson’s Disease tremor behaviors that were considered hard to interpret can be explained by control systems modeling of mid-level motor control. The model in this paper includes stretch reflex loop with feedback delay and tonically controlled antagonist muscles. It also includes Basal Ganglia circuit that commands (schedules) gain changes in the reflex feedback loop. Computational analysis of the control systems model shows how the gain…

Recognizing Gastrointestinal Symptoms as Early Indicators of Parkinson Disease

Laren Becker, MD, PhD, a physician-scientist at Stanford University, discussed how gastrointestinal dysfunction and peripheral dopaminergic activity impact Parkinson disease treatment and progression.

Advanced MRI Reveals Putamen Changes in Parkinson’s

In a groundbreaking advancement that could reshape the way Parkinson’s disease is diagnosed and monitored, researchers have utilized sophisticated multiparametric quantitative magnetic resonance imaging (MRI) to reveal hitherto unseen microstructural changes in the putamen, a critical brain region affected by the disease. This study, recently published in npj Parkinsons Disease, harnesses cutting-edge neuroimaging techniques that […]
