Objective: To assess the role of onset age in the results of bilateral subthalamic nucleus deep brain stimulation (STN-DBS), we carried out a retrospective study of two groups of patients regarding age at disease onset.
Methods: We compared, up to 3 years after surgery, the clinical effects, quality of life and the levodopa equivalent daily dose (LEDD) in patients with young-onset Parkinson's disease (onset age <50 years, YOPD) vs patients with older-onset Parkinson's disease (onset age ≥50 years, OOPD).
Results: A dramatic improvement in motor symptoms was equally observed in both groups of patients after DBS. The improvements of the Unified Parkinson's Disease Rating Scale part III motor scale (UPDRS-III) score, axial sub-score and non-axial sub-score from baseline gradually decreased over time. The benefit of STN-DBS for the axial symptoms decreased most rapidly, which directly resulted in a progressive decline in stimulation efficacy in both groups. Nevertheless, the improvement in non-axial symptoms after DBS was remarkable and long-lasting. The quality of life in both groups were also improved after DBS but were slightly decreased in the following years. The reduced LEDD were equivalent in both groups.
Conclusions: STN-DBS alleviates motor symptoms and improves quality of life equally in both YOPD and OOPD patients with similar LEDD. The initial therapeutic benefit of STN-DBS for PD gradually decreases over time, mainly due to the progression of PD and the rapid withdrawal of the benefit for axial symptoms.

Planned Surgical Trajectory Affects Clinical Motor Outcome in Deep Brain Stimulation Targeted at Subthalamic Nucleus for Parkinson's Disease.

Background And Objectives: Surgical planning is critical to achieve optimal outcome in deep brain stimulation (DBS). The relationship between clinical outcomes and DBS electrode position relative to subthalamic nucleus (STN) is well investigated, but the role of surgical trajectory remains unclear. We sought to determine whether preoperatively planned DBS lead trajectory relates to adequate motor outcome in STN-DBS for Parkinson's disease (PD).

Background: Cognitive networks impairments are common in neuropsychiatric disorders like Attention Deficit Hyperactivity Disorder (ADHD), bipolar disorder (BD), and schizophrenia (SZ). While previous research has focused on specific brain regions, the role of the procedural memory as a type of long-term memory to examine cognitive networks impairments in these disorders remains unclear. This study investigates alterations in resting-state functional connectivity (rs-FC) within the procedural memory network to explore brain function associated with cognitive networks in patients with these disorders.

Background: The globus pallidus internus (GPi) is the traditional evidence-based deep brain stimulation (DBS) target for treating dystonia. Although patients with isolated "primary" dystonia respond best to GPi-DBS, some are primary or secondary nonresponders (improvement <25%), showing variability in clinical response.
Objective: The aim was to survey current practices regarding alternative DBS targets for isolated dystonia patients with focus on nonresponders to GPi-DBS.
Diurnal fluctuations of subthalamic nucleus local field potentials follow naturalistic sleep-wake behavior in Parkinson's disease.

Department of Neurology, University of Colorado Anschutz Medical Campus, Aurora, CO USA.
Study Objectives: Deep brain stimulation (DBS) of the subthalamic nucleus (STN) may improve sleep dysfunction, a common non-motor symptom of Parkinson disease (PD). Improvement in motor symptoms correlates with DBS-suppressed local field potential (LFP) activity, particularly in the beta frequency (13 - 30 Hz). Although well-characterized in the short term, little is known about the innate progression of these oscillations across the sleep-wake cycle.
