ABSTRACT
OBJECTIVE: Our purpose was to present and discuss the psychiatric diagnoses of patients who presented psychogenic non-epileptic seizures (PNES) during video-electroencephalographic monitoring (VEEG). METHODS: Out of 98 patients, a total of 28 patients presented PNES during the diagnostic procedure. In those cases in which the PNES that occurred during VEEG were validated by clinical history (clinical validation), and by showing the recorded event on video to an observer close to the patient (observer validation), was defined psychogenic non-epileptic seizure disorder (PNESD). Psychiatric diagnoses were made according to DSM-IV. RESULTS: In 27, psychogenic non-epileptic seizures disorder was diagnosed. Fourteen patients presented only with psychogenic non-epileptic seizure disorder, 13 with both psychogenic non-epileptic seizures disorder and epilepsy, and one patient with epilepsy only. Psychiatric diagnoses were: 17 (63%) patients with conversion disorder, five (19%) with somatization disorder, two (7%) with dissociative disorder NOS, two (7%) with post-traumatic stress disorder and one (4%) with undifferentiated somatoform disorder. CONCLUSIONS: Dissociative-conversion non-epileptic seizures are the most frequent finding, representing the pseudoneurological manifestation of mental disorders that have these symptoms as a common feature. Provisionally, they may be defined as dissociative-conversion non-epileptic seizure disorders.

The purpose of this survey was to evaluate the experience of Brazilian psychiatrists in treatment, formal training, attitudes, and knowledge with respect to epilepsy (and associated mental disorders). One hundred fifty-seven Brazilian psychiatrists completed a specially developed questionnaire. Most (95%) had previously treated patients with epilepsy and mental disorders. About one-third (35%) admitted a lack of any formal training in epilepsy, and only 46% confirmed having received some formal training in mental disorders related to epilepsy. Eighty percent were dissatisfied with their knowledge. Three knowledge-based questions were answered correctly by only 10%. Almost half (48%) admitted that among psychiatrists, prejudice exists toward patients with epilepsy. Difficulties with treatment (50%) and lack of knowledge of epilepsy (50%) were considered the main causes of such prejudice. These data indicate an urgent need for improvement in education on epilepsy and associated mental disorders, as well as inclusion of formal epilepsy training in psychiatry residency programs.
