Psychogenic (nonepileptic) seizures are among the most common and serious of all psychogenic neurological disorders. They account for approximately 20% of all intractable seizure disorders referred to comprehensive epilepsy centers and present with a reported annual incidence of approximately 4% that of true epilepsy. These events are serious and disabling. Indeed, compared with patients with t...

As the field of movement disorders has developed and matured over the past 25 years, psychogenic movement disorders have become increasingly recognized in subspecialty clinics. The diagnosis can be challenging and should be based on positive features rather than a purely exclusionary approach. The clinical phenotype can be quite varied, although certain categories of abnormal movement are more ...

Psychogenic movement disorders are heterogeneous and diagnostically challenging. Despite the growing literature on adult forms, clinical features in children have received relatively little attention. We retrospectively reviewed medical records and video of patients <18 years diagnosed with a psychogenic movement disorder at our institute between 2007 and 2010. We identified 14 patients (6 male...

INTRODUCTION Psychogenic Non Epileptic Seizures (PNES) have been theorized to reflect a learned pattern of avoidant behavior to deal with stressors. Although such observation may be relevant for our understanding of the etiology of PNES, evidence for this theory is largely build on self-report investigations and no studies have systematically tested actual avoidance behavior in patients with PN...

BACKGROUND the occurrence of psychogenic non-epileptic seizures (PNES) is estimated to be between 2 to 33 cases in every 100,000 inhabitants. The number of patients with PNES reaches 19% of those treated as epileptics. Patients with PNES are treated as if they had intractable epilepsy, with unsatisfactory results even after medication treatment is used to its maximum. The aim of this study is t...

Huntington's disease (HD) is a neurodegenerative condition characterised by motor dysfunction with involuntary movements and loss of voluntary control, cognitive deterioration and psychiatric problems. We report a 51-year-old man with early HD who experienced stereotyped episodes of repetitive, purposeless complex movements and unresponsiveness. His neurological examination was compatible with ...

The aim of this study was to evaluate the frequency of epilepsy in patients who presented psychogenic non-epileptic seizures (PNES). The evaluation was carried out during intensive VEEG monitoring in a diagnostic center for epilepsy in a university hospital. The difficulties involved in reaching this diagnosis are discussed. Ninety-eight patients underwent intensive and prolonged video-electroe...
