abstract explaining the etiology of complex regional pain syndrome (crps) from the psychogenic model is exceedingly unsophisticated, because neurocognitive deficits, neuroanatomical abnormalities, and distortions in cognitive mapping are features of crps pathology. more importantly, many people who have developed crps have no history of mental illness. the psychogenic model offers comfort to ph...

BACKGROUND Munchausen syndrome presenting with psychogenic dystonia is a rare condition. PHENOMENOLOGY SHOWN A psychogenic dystonia case presenting with an acute onset of retrocollis, lower limb dystonia and bizarre gait was diagnosed as Munchausen syndrome. EDUCATIONAL VALUE Recognizing psychogenic dystonia avoids unnecessary investigations and provides successful treatment.

A 2 years and 9 months old boy attended to a gastroenterology clinic of pediatric hospital for investigation of recurrent and intractable vomiting. He had post prandial, non-projectile, non-bilious emesis since past 2 years. Since the onset of illness, he was carried to many doctors and underwent extensive laboratory investigations. Because all of the science lab and imaging work up for etiolog...

BACKGROUND Convergence spasm refers to transient ocular convergence, miosis and accommodation associated with disconjugate gaze mimicking abducens palsy. While it may be a manifestation of brainstem pathology, this sign is often associated with conversion (somatisation) disorders and, if unrecognised as a sign of a psychogenic disorder, it may lead to unnecessary and occasionally invasive evalu...

Psychogenic illness during disasters can cripple emergency healthcare services. Almost all research into this phenomenon has been retrospective and observational, and much of it suggests that media coverage can amplify psychogenic outbreaks. But there is little empirical evidence that this is true or that, conversely, media reports can mitigate psychogenic symptoms. In their work experimentally...

The prevalence of psychogenic non-epileptic seizures is difficult to estimate. We propose an estimate based on a calculation. We used the following data, which are known or have been estimated, and are generally accepted. A prevalence of epilepsy of 0.5-1%; a proportion of intractable epilepsy of 20-30%; a percentage of these referred to epilepsy centers of 20-50%; and a percentage of patients ...

A confident clinical diagnosis of psychogenic tremor is often possible, but, in some cases, a "laboratory-supported" level of certainty would aid in early positive diagnosis. Various electrophysiological tests have been suggested to identify patients with psychogenic tremor, but their diagnostic reliability has never been assessed "head to head" nor compared to forms of organic tremor other tha...

We assessed the duration and severity of tremor in a real-life ambulatory setting in patients with psychogenic and organic tremor by actigraphy, and compared this with self-reports of tremor over the same period. Ten participants with psychogenic tremor and eight with organic tremor, diagnosed using standardized clinical criteria, were studied. In an explicit design, participants were asked to ...

The aim of this study was to compare out of camera view seizure occurrence rates between psychogenic non-epileptic and epileptic seizures during long-term video-EEG monitoring. From 1996 to 2001, 208 adult patients were monitored in 212 sessions, and 196 patients were included in the study. Depending on video-EEG recordings and witnessed accounts, 18 of the patients had no seizures recorded, 16...
