BACKGROUND Clinical and ethical implications of personality and mood changes in Parkinson's disease (PD) patients treated with subthalamic deep brain stimulation (STN-DBS) are under debate. Although subjectively perceived personality changes are often mentioned by patients and caregivers, few empirical studies concerning these changes exist. Therefore, we(More)
Deep brain stimulation (DBS) is an established treatment option for some movement disorders, in particular Parkinson's disease. Only recently, a number of promising studies with small samples of patients have been published in which impressive therapeutic outcomes achieved by DBS in otherwise treatment-resistant obsessive-compulsive disorder, major(More)
Cholinergic neurons of the medial forebrain are considered important contributors to brain plasticity and neuromodulation. A reduction of cholinergic innervation can lead to pathophysiological changes of neurotransmission and is observed in Alzheimer's disease. Here we report on six patients with mild to moderate Alzheimer's disease (AD) treated with(More)
Dysfunctional basal ganglia loops are thought to underlie the clinical picture of Tourette syndrome (TS). By altering dopaminergic activity in the affected neural structures, bilateral deep brain stimulation is assumed to have a modulatory effect on dopamine transmission resulting in an amelioration of tics. While the majority of published case reports(More)
OBJECTIVE To study patients' expectations of subthalamic deep brain stimulation (STN-DBS) and their subjective perceived outcome, by using qualitative and quantitative methods in Parkinson's disease (PD). METHODS PD patients were prospectively examined before and 3 months after surgery. Semistructured interviews regarding preoperative expectations and(More)
BACKGROUND Since its first application in 1999, the potential benefit of deep brain stimulation (DBS) in reducing symptoms of otherwise treatment-refractory Tourette syndrome (TS) has been documented in several publications. However, uncertainty regarding the ideal neural targets remains, and the eventuality of so far undocumented but possible negative(More)
Ethical evaluation of deep brain stimulation as a treatment for Parkinson's disease is complicated by results that can be described as involving changes in the patient's identity. The risk of becoming another person following surgery is alarming for patients, caregivers and clinicians alike. It is one of the most urgent conceptual and ethical problems(More)
Deep brain stimulation (DBS) is a non-destructive, adjustable, and mainly reversible method of continuously giving electrical impulses into a small area of the brain via implanted electrodes. It has been established as a standard form of treatment for specific cases of Parkinson's disease, essential tremor and dystonia. It is currently being evaluated for(More)
To study the caregivers' perception of their own well-being 1 year after subthalamic deep brain stimulation (STN-DBS) surgery in Parkinson's disease (PD) patients, using a qualitative and quantitative approach. 25 patients and caregivers, living together in partnerships, were examined before and at 3-month and 1-year follow-up (FU) after STN-DBS surgery.(More)
Deep brain stimulation (DBS) has proven to be a successful therapeutic approach in several patients with movement disorders such as Parkinson's disease and dystonia. Hitherto its application was mainly restricted to advanced disease patients resistant to medication or with severe treatment side effects. However, there is now growing interest in earlier(More)
