Subthalamic Stimulation Improves Short-Term Satisfaction with Life and Treatment in Parkinson's Disease.

The effect of subthalamic stimulation (STN-DBS) on patients' personal satisfaction with life and their Parkinson's disease (PD) treatment is understudied, as is its correlation with quality of life (QoL). Therefore, we tested the hypothesis that STN-DBS for PD enhances satisfaction with life and treatment. In a prospective, multicenter study with a 6-month follow-up involving 121 patients, we measured the main outcomes using the Satisfaction with Life and Treatment Scale (SLTS-7).

Predictors of short-term anxiety outcome in subthalamic stimulation for Parkinson's disease.

The effects of subthalamic nucleus deep brain stimulation (STN-DBS) on anxiety in Parkinson's disease (PD) are understudied. We identified clinical predictors of STN-DBS effects on anxiety in this study. In this prospective, open-label, multicentre study, we assessed patients with anxiety undergoing STN-DBS for PD preoperatively and at 6-month follow-up postoperatively.

Neurostimulation for Advanced Parkinson Disease and Quality of Life at 5 Years: A Nonrandomized Controlled Trial.

Importance: Deep brain stimulation of the subthalamic nucleus (STN-DBS) improves quality of life (QOL) in patients with advanced Parkinson disease (PD). However, controlled studies with more than 3 years of follow-up are lacking.

Objective: To investigate the long-term effects of STN-DBS on QOL compared with standard-of-care medication (MED).

Stratifying quality of life outcome in subthalamic stimulation for Parkinson's disease.

Background: Subthalamic nucleus deep brain stimulation (STN-DBS) for Parkinson's disease (PD) improves quality of life (QoL), motor and non-motor symptoms (NMS). However, in previous studies, 43%-49% of patients did not experience clinically relevant postoperative QoL improvement. To inform individualised prediction of postoperative QoL improvement, we developed a stratification analysis of QoL outcomes based on preoperative non-motor total burden, severity of motor progression and motor response in levodopa challenge tests.

SOP: acute hyperkinetic movement disorders.

Introduction: Movement disorders emergencies describe acute-onset neurological conditions in which a delay of recognition and treatment may cause severe morbidity and mortality of patients. Hyperkinetic movement disorders include tremor, chorea/ballism, dystonia, myoclonus, and tics. Here we present a standard operating procedure (SOP) for the diagnostic work-up and different treatment options depending on the phenomenology as well as the aetiology of underlying diseases.

Gender differences in referrals for deep brain stimulation for essential tremor.

Deep brain stimulation (DBS) is an established treatment for essential tremor (ET). Gender differences in DBS have been recognized for Parkinson's disease. In this systematic chart review, we also observed a gender differences in DBS for ET.

Non-motor effects of deep brain stimulation in Parkinson's disease motor subtypes.

Introduction: Deep brain stimulation (DBS) is a well-established treatment for patients with Parkinson's disease (PD) improving quality of life, motor, and non-motor symptoms. However, non-motor effects in PD subtypes are understudied. We hypothesized that patients with 'postural instability and gait difficulty' (PIGD) experience more beneficial non-motor effects than 'tremor-dominant' patients undergoing DBS for PD.

The New Satisfaction with Life and Treatment Scale (SLTS-7) in Patients with Parkinson's Disease.

Background: The satisfaction with life and, in particular, with treatment in Parkinson's disease (PD) is understudied.

Objective: To explore a new 7-item rating tool assessing satisfaction with life and treatment (SLTS-7) in PD.

Methods: In this cross-sectional, multi-center study, including patients screened for advanced therapies, psychometric characteristics of the SLTS-7 were analyzed.

Predictors of short-term impulsive and compulsive behaviour after subthalamic stimulation in Parkinson disease.

Background: The effects of subthalamic stimulation (subthalamic nucleus-deep brain stimulation, STN-DBS) on impulsive and compulsive behaviours (ICB) in Parkinson's disease (PD) are understudied.

Objective: To investigate clinical predictors of STN-DBS effects on ICB.

Methods: In this prospective, open-label, multicentre study in patients with PD undergoing bilateral STN-DBS, we assessed patients preoperatively and at 6-month follow-up postoperatively.

Non-motor predictors of 36-month quality of life after subthalamic stimulation in Parkinson disease.

To identify predictors of 36-month follow-up quality of life (QoL) outcome after bilateral subthalamic nucleus deep brain stimulation (STN-DBS) in Parkinson's disease (PD). In this ongoing, prospective, multicenter international study (Cologne, Manchester, London) including 73 patients undergoing STN-DBS, we assessed the following scales preoperatively and at 6-month and 36-month follow-up: PD Questionnaire-8 (PDQ-8), NMSScale (NMSS), Scales for Outcomes in PD (SCOPA)-motor examination, -activities of daily living, and -complications, and levodopa equivalent daily dose (LEDD). We analyzed factors associated with QoL improvement at 36-month follow-up based on (1) correlations between baseline test scores and QoL improvement, (2) step-wise linear regressions with baseline test scores as independent and QoL improvement as dependent variables, (3) logistic regressions and receiver operating characteristic curves using a dichotomized variable "QoL responders"/"non-responders".
