INTRODUCTION AND DEVELOPMENT The subthalamic nucleus (STN) plays a crucial part in the pathophysiology of Parkinsonism. Its inactivation improves all the main signs and symptoms of Parkinson's disease. Surgery of the STN in patients with the disease is effective and the benefit/risk relationship very favorable. Although the dyskinesias are not a definite(More)
We evaluated motor function in 41 consecutive PD patients undergoing unilateral MRI/microelectrode-guided posteroventral pallidotomy to determine whether the motor effects of levodopa therapy change after surgery. Total Unified Parkinson's Disease Rating Scale motor "off" and motor "on" subscores all improved and the rapidity of action, magnitude, and(More)
BACKGROUND The aim of this study is to compare the effectiveness of two exposure procedures on habituation of emotional responses to food stimuli: (a) exposure to external cues (food images) without eating forbidden food (CE) and (b) exposure to external cues eating forbidden food (with purge prevention). The influence of craving-trait and mood state on the(More)
The aim of the study was to assess the influence on reactivity to food images of the following variables: craving-trait, positive or negative mood state, and food restriction. Emotional modulation of the defense startle reflex (RMS) was assessed in 26 women at risk of suffering from bulimia nervosa; they were assigned one of to two groups: high(More)
We review the present status of surgery for Parkinson's disease. Surgical options for Parkinson's disease are rapidly spanding. The main objectives of surgical techniques are to restore the dopaminergic deficit in the striatum (transplantation) and to normalize the neuronal activity of the subthalamic-pallidal circuit (pallidotomy and deep brain(More)
Although substantial therapeutic advances have been developed during the last decade, L-dopa remains as the most successful treatment for Parkinson's disease. However, about 80% of the patients show motor and psychiatric complications after several years of levodopa treatment. Thus, new therapeutic approaches have been undertaken during the last decade in(More)
