Article Synopsis
- The study investigates how subthalamic nucleus deep brain stimulation (STN-DBS) surgery affects cognitive aspects of motor control in people with Parkinson's disease (PD) over time.
- Researchers compared participants' saccade latency and reach reaction time before surgery and about 8 months after surgery while off medication and stimulation.
- Results showed that both saccade latency and reach reaction time significantly worsened post-surgery, suggesting negative long-term cognitive impacts from the surgery.
Objectives: This study sought to elucidate the diagnostic performance of 0.55 T magnetic resonance imaging (MRI) for pediatric dental imaging, specifically in terms of the image quality (IQ) for detecting ectopic and/or supernumerary teeth, compared with routine ultra-low-dose computed tomography (ULD-CT) of the jaw.
Materials And Methods: A total of 16 pediatric patients (mean age: 12.
The motor impairments experienced by people with Parkinson's disease (PD) are exacerbated during memory-guided movements. Despite this, the effect of antiparkinson medication on memory-guided movements has not been elucidated. We evaluated the effect of antiparkinson medication on motor control during a memory-guided reaching task with short and long retention delays in participants with PD and compared performance to age-matched healthy control (HC) participants.

Methods: Eleven participants with PD and STN-DBS completed the visually-guided saccade paradigms with OFF, RIGHT, LEFT, and BOTH stimulation. Rightward saccade performance was evaluated for three paradigms and two target eccentricities.
Background: Antiparkinson medication and subthalamic nucleus deep brain stimulation (STN-DBS), two common treatments of Parkinson's disease (PD), effectively improve skeletomotor movements. However, evidence suggests that these treatments may have differential effects on eye and limb movements, although both movement types are controlled through the parallel basal ganglia loops.
Objective: Using a task that requires both eye and upper limb movements, we aimed to determine the effects of medication and STN-DBS on eye and upper limb movement performance.
