2008, Handbook of Clinical NeurologyCitation Excerpt :Aggregate data from dexamethasone suppression/corticotropin-releasing hormone tests are used in depression and post-traumatic stress disorder research but do not reliably establish the diagnoses in individual patients (Baghai et al., 2002; Yehuda et al., 2004). Motor evoked potentials and somatosensory evoked potentials have been used in conversion paralysis and anesthesia, respectively, for assisting diagnosis in small case series (Levy and Mushin, 1973; Morota et al., 1994). Structural and functional neuroimaging reveal volumetric reductions and perfusion deficits in mood and anxiety disorders in aggregate data.
Hysterical conversion and brain function
2005, Progress in Brain ResearchCitation Excerpt :On the other hand, a few other studies have reported subtle changes in paradigms that were slightly more sophisticated than just detection of simple tactile stimuli. For instance, tactile stimuli close to perceptual threshold may fail to produce normal evoked potentials in patients with sensory conversion symptoms, even when stimuli above threshold still produce normal responses (Levy and Mushin, 1973). In addition, anomalies in the rate of habituation to repeated stimulations were observed in hysterical conversion using SEPs (Moldofsky and England, 1975) as well as skin-conductance reactivity (Horvath et al., 1980).
