Neural 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 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 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 کاملReview Conversion motor paralysis disorder: overview and rehabilitation model
It is important to consider a dierential diagnosis between paralysis on an organic basis and paralysis and disability due to psychological mechanisms in people with physical impairment secondary to trauma, without evidence of organic etiology. We review the most dramatic type of conversion disorder (CD) ± `Conversion Motor Paralysis'. Recent important medical literature concerning the accepted...
متن کاملNeural correlates of recall of life events in conversion disorder.
IMPORTANCE Freud argued that in conversion disorder (CD) the affect attached to stressful memories is "repressed" and "converted" into physical symptoms, although this has never been subject to scientific study to our knowledge. OBJECTIVE To examine the neural correlates of recall of life events judged to be of causal significance in CD. DESIGN, SETTING, AND PARTICIPANTS Case-control study....
