Emotional stimuli and motor conversion disorder.
Conversion disorder is characterized by neurological signs and symptoms related to an underlying psychological issue. Amygdala activity to affective stimuli is well characterized in healthy volunteers with greater amygdala activity to both negative and positive stimuli relative to neutral stimuli, and greater activity to negative relative to positive stimuli. We investigated the relationship be...
متن کاملElectrophysiological correlates of motor conversion disorder.
In patients with a functional (psychogenic) paresis, motor conduction tests are, by definition, normal. We investigated whether these patients exhibit an abnormal motor excitability. Four female patients with a functional paresis of the left upper extremity were studied using transcranial magnetic stimulation (TMS). We investigated motor thresholds, intracortical inhibition and intracortical fa...
متن کاملNeural correlates of motor conversion disorder.
Conversion Disorder affects voluntary motor and sensory function and involves unexplained neurological symptoms without an organic cause. Many researchers have attempted to explain how these symptoms arise but the neural correlates associated with Conversion Disorder remain largely unknown to clinicians and neuroscientists alike. This review focuses on investigations of Conversion Disorder (wit...
متن کاملNeural correlates of conversion disorder: overview and meta-analysis of neuroimaging studies on motor conversion disorder
BACKGROUND Conversion Disorders (CD) are prevalent functional disorders. Although the pathogenesis is still not completely understood, an interaction of genetic, neurobiological, and psychosocial factors is quite likely. The aim of this study is to provide a systematic overview on imaging studies on CDs and investigate neuronal areas involved in Motor Conversion Disorders (MCD). METHODS A sys...
متن کاملThe Effect of Worry on Physiological and Affective Reactivity to Emotional Stimuli in Generalized Anxiety Disorder and Normal Participants
The purpose of this study was examination of effect of worry on both physiological and emotional responding to negative emotional stimuli. This study was a semi-experimental research design with pretest, posttest and control group. 41 participants with generalized anxiety disorder (21 person induce relaxation and 20 person induce worry) and 39 nonanxious control participants (19 person induce r...
