Psychological trauma, somatization, dissociation, and psychiatric comorbidities in patients with psychogenic nonepileptic seizures compared with those in patients with intractable partial epilepsy.

Objective: The objective of this study was to compare patients with intractable epilepsy with patients with psychogenic nonepileptic seizures (PNES) on the presence of psychological traumas, clinical factors, and psychological measures of somatization and dissociation.

Background: Several studies have reported a high prevalence of psychological trauma in patients with PNES, while less have examined the prevalence of psychological trauma in patients with epilepsy and compared both groups. Reports have been somewhat divergent with some describing significantly higher prevalence in physical abuse, others, in emotional abuse/neglect, and others, in sexual abuse in patients with PNES compared with those in patients with epilepsy.

Are there gender differences in those diagnosed with psychogenic nonepileptic seizures?

Objective: The objective of the study was to determine whether male and female populations of patients with psychogenic nonepileptic seizures (PNES) differ, in terms of demographic, social/clinical, and etiological factors as well as psychological measures.

Background: Psychogenic nonepileptic seizures are overrepresented by females; therefore, information about PNES in males is limited. Only a handful of studies have examined PNES and gender, and of those, one was a literature review and with the exception of two, most have had small sample sizes.

Test-retest reliability of cortical language mapping in a patient with refractory focal epilepsy: 11 years later.

Electrical stimulation mapping (ESM) is considered the gold standard for identification of essential language cortex and is especially important in patients for whom classic language landmarks are less useful because of reorganization in response to epileptogenic or neoplastic cortex. However, little is known regarding the reliability of the procedure, particularly over extended time intervals. The authors present the case of a young man with refractory left temporal lobe epilepsy in the setting of a low-grade left temporal tumor who had undergone intraoperative language mapping at age 14 years and repeat mapping at age 25.

Survey results regarding use of the Boston Naming Test: Houston, we have a problem.

Members of the National Academy of Neuropsychology were surveyed in 2005 to assess then current practices regarding Boston Naming Test (BNT) administration, interpretation, and reporting procedures. Nearly half of 445 respondents followed discontinuation rules that differed from instructions published with the test, and nearly 10% did not administer items in reverse order to achieve the required 8 consecutive item basal. Of further concern, between 40% and 55% of respondents indicated that they did not interpret BNT scores in light of linguistic and ethnic background, and over 25% reported that they did not consider educational level.

Performance on Standard Indexes of Effort Among Patients with Dementia.

Assessment of response validity is an integral part of neuropsychological practice. Although many studies have demonstrated the efficacy of stand alone and embedded effort measures in a variety of medical and compensation-seeking contexts, much less is known about the robustness of these measures in elderly populations, particularly in patients with dementia. Although older adults may be viewed as less likely to intentionally feign symptoms for an external gain, there are a variety of other factors that could result in suboptimal effort, including fatigue, lack of interest or cooperation in the testing process, or failure to fully appreciate the implications of the assessment on treatment care and outcome.

Examination of various WMS-III logical memory scores in the assessment of response bias.

The assessment of response validity during neuropsychological evaluation is an integral part of the testing process. Research has increasingly focused on the use of "embedded" effort measures (derived from standard neuropsychological tasks) because they do not require additional administration time and are less likely to be identified as effort indicators by test takers because of their primary focus as measures of cognitive function. The current study examined the clinical utility of various WMS-III Logical Memory scores in detecting response bias, as well as the Rarely Missed Index, an embedded effort indicator derived from the WMS-III Logical Memory Delayed Recognition subtest.
