Long-term neuropsychological outcomes of deep brain stimulation in early-stage Parkinson's disease.

Introduction: The pilot trial of deep brain stimulation (DBS) in early-stage Parkinson's disease (PD) randomized 30 patients (medication duration 0.5-4 years; without dyskinesia or motor fluctuations) to receive optimal drug therapy alone (early ODT) or subthalamic nucleus (STN) DBS plus ODT (early DBS + ODT). This study reports long-term neuropsychological outcomes from the early DBS pilot trial.

Traumatic Brain Injury-Related Attention Deficits in Children: A Controlled Treatment Trial with Lisdexamfetamine Dimesylate (Vyvanse).

Attention deficits are among the most common and persistent impairments resulting from traumatic brain injury (TBI). This study was the first to examine the effects of lisdexamfetamine dimesylate (LDX, Vyvanse) in treating TBI-related attention deficits in children. It was an extension of a previous controlled trial with adults.

Neuropsychological effects of deep brain stimulation in subjects with early stage Parkinson's disease in a randomized clinical trial.

Background: Deep brain stimulation (DBS) is an effective treatment for patients with advanced Parkinson's disease (PD) and motor symptom complications. Recently, attention has been focused on whether offering DBS earlier in the course of PD is beneficial.

Objective: The purpose of this study was to determine the effects of DBS on neuropsychological functioning in subjects with early stage PD.

Traumatic brain injury-related attention deficits: treatment outcomes with lisdexamfetamine dimesylate (Vyvanse).

Background And Objectives: Attention deficits are often among the most persistent and debilitating impairments resulting from traumatic brain injury (TBI). This study examined the effects of lisdexamfetamine dimesylate (Vyvanse) in treating attention deficits due to moderate-to-severe TBI. It was the first study of lisdexamfetamine dimesylate with this population and, in fact, was the first controlled trial in this area examining a stimulant medication option other than methylphenidate.

Subthalamic nucleus deep brain stimulation in early stage Parkinson's disease.

Background: Deep brain stimulation (DBS) is an effective and approved therapy for advanced Parkinson's disease (PD), and a recent study suggests efficacy in mid-stage disease. This manuscript reports the results of a pilot trial investigating preliminary safety and tolerability of DBS in early PD.

Methods: Thirty subjects with idiopathic PD (Hoehn & Yahr Stage II off medication), age 50-75, on medication ≥6 months but ≤4 years, and without motor fluctuations or dyskinesias were randomized to optimal drug therapy (ODT) (n = 15) or DBS + ODT (n = 15).

Pilot study assessing the feasibility of applying bilateral subthalamic nucleus deep brain stimulation in very early stage Parkinson's disease: study design and rationale.

Background: Deep brain stimulation provides significant symptomatic benefit for people with advanced Parkinson's disease whose symptoms are no longer adequately controlled with medication. Preliminary evidence suggests that subthalamic nucleus stimulation may also be efficacious in early Parkinson's disease, and results of animal studies suggest that it may spare dopaminergic neurons in the substantia nigra.

Objective: We report the methodology and design of a novel Phase I clinical trial testing the safety and tolerability of deep brain stimulation in early Parkinson's disease and discuss previous failed attempts at neuroprotection.

Deep brain stimulation for early-stage Parkinson's disease: an illustrative case.

Objectives: Subthalamic nucleus (STN) deep brain stimulation (DBS) is an effective intervention in advanced Parkinson's disease (PD), but its efficacy and safety in early PD are unknown. We are conducting a randomized pilot trial investigating DBS in early PD. This report describes one participant who received bilateral STN-DBS.

Depression and intelligence in patients with Parkinson's disease and deep-brain stimulation.

The goal of this study is to examine the association of depression with intelligence and education in patients with Parkinson's disease treated with bilateral subthalamic nucleus stimulation (STN-DBS). The literature has been contradictory concerning depression in Parkinson's disease patients. Some studies have shown less depression in Parkinson's disease patients with more education not treated with STN-DBS.

Deep brain stimulation of the subthalamic nucleus reduces antiparkinsonian medication costs.

This study reports a retrospective analysis of 16 patients to determine changes in medication costs associated with deep brain stimulation of the bilateral subthalamic nucleus (DBS B-STN). Antiparkinsonian medication (APMED) costs were evaluated pre- and post-operatively at 1 and 2 years, based on prescribed dosages. After treatment with DBS, patients experienced a 32% reduction in APMED costs after 1 year and a 39% reduction after 2 years.
