Deep Brain Stimulation of the Subthalamic Nucleus Improves Lexical Switching in Parkinsons Disease Patients
OBJECTIVE Reduced verbal fluency (VF) has been reported in patients with Parkinson's disease (PD), especially those treated by Deep Brain Stimulation of the subthalamic nucleus (STN DBS). To delineate the nature of this dysfunction we aimed at identifying the particular VF-related operations modified by STN DBS. METHOD Eleven PD patients performed VF tasks in their STN DBS ON and OFF conditio...
متن کاملElectrode Position and Current Amplitude Modulate Impulsivity after Subthalamic Stimulation in Parkinsons Disease—A Computational Study
Background: Subthalamic Nucleus Deep Brain Stimulation (STN-DBS) is highly effective in alleviating motor symptoms of Parkinson's disease (PD) which are not optimally controlled by dopamine replacement therapy. Clinical studies and reports suggest that STN-DBS may result in increased impulsivity and de novo impulse control disorders (ICD). Objective/Hypothesis: We aimed to compare performance o...
متن کاملParkinson's disease, the subthalamic nucleus, inhibition, and impulsivity.
Although Parkinson's disease (PD) is primarily considered a disorder of initiation of actions, patients also have deficits in inhibitory control, both in the motor and cognitive domains. Impulse control disorders, which can develop in association with dopaminergic medication in a small proportion of patients with PD, are the symptoms most commonly considered as representing inhibitory deficits....
متن کاملSubthalamic nucleus stimulation and somatosensory temporal discrimination in Parkinson's disease.
Whereas numerous studies document the effects of dopamine medication and deep brain stimulation on motor function in patients with Parkinson's disease, few have investigated deep brain stimulation-induced changes in sensory functions. In this study of 13 patients with Parkinson's disease, we tested the effects of deep brain stimulation on the somatosensory temporal discrimination threshold. To ...
متن کامل[Electrophysiology of subthalamic nucleus in normal and Parkinson's disease].
Subthalamic nucleus (STN) has been known to play an important role in the regulation of cortico-basal ganglia-thalamo-cortical loop. STN neurons have pacemaking activitiy and their firing pattern can switch from spike mode to bursting mode when membrane potential becomes hyperpolarized. Recent study has shown that STN neurons show marked increase in burst and oscillatory activity during the dop...
