Stigma and safe havens: A medical sociological perspective on African-American female epilepsy patients

PURPOSE Very little is known about the attitudes and behaviors of minorities with epilepsy. This pilot study explored access to health care, help-seeking behaviors, and adherence to treatment among African-American females with epilepsy. METHODS Ethnographic interviews were conducted with 10 African-American female adults. RESULTS Findings indicate four major obstacles to care: limited financial resources, lack of knowledge about epilepsy among African-Americans, poor patient-provider communication, and lack of social support. Social support impacted individuals seeking surgery, and also affected purchasing medication, adherence to medical treatment, and needed transportation. Lack of knowledge and misinformation about epilepsy in the African-American community and poor communication with physicians contribute to the social stigma felt by these patients. CONCLUSIONS The behavioral epidemiology of epilepsy among African-Americans is lacking. This disease exacerbates health disparities for this population. These findings point to a need for a safe haven for these individuals.

Assessment of quality of life among the elderly with epilepsy.

As the elderly represent the most rapidly growing population in the United States, it is critical that physicians are capable of managing their chronic illnesses, including epilepsy. Optimal treatment of epilepsy integrates an understanding of health-related quality of life (HRQOL), yet limited information is available to guide HRQOL issues among the elderly. This study found that seniors with epilepsy do not have poorer HRQOL compared with general epilepsy populations. However, when compared with general populations without epilepsy, seniors with epilepsy report a significantly lower HRQOL across all domains. Multiple factors may uniquely affect HRQOL among elderly populations with epilepsy: aging, comorbid conditions, and epilepsy variables. However, to our knowledge, no one instrument addresses all of these aspects. The development of HRQOL instruments specifically for an elderly population with epilepsy may be useful and needed.

Can hypnosis differentiate epileptic from nonepileptic events in the video/EEG monitoring unit? Data from a pilot study

OBJECTIVE An estimated 24% of patients referred to epilepsy clinics actually have nonepileptic seizures. Various procedures have been used to precipitate nonepileptic events. The goal of this study was to use hypnosis in seizure provocation and differentiation between epileptic and nonepileptic seizure events. METHODS Fifty study participants were enrolled from the Via Christi Comprehensive Epilepsy Centers video/electroencephalography unit. Patients underwent the Hypnotic Induction Profile (HIP) to assess susceptibility to hypnosis. After completion of the HIP, participants underwent hypnosis by a physician trained to do so. They received a hypnotic suggestion to have a seizure. All seizure-like events were classified as either an epileptic, nonepileptic, or undetermined event based on whether or not the patient had abnormal EEG activity during the event. RESULTS Of the 50 participants enrolled, 3 withdrew consent, resulting in 47 participants. Seven (15%) participants failed to have an event of any type and were classified as undetermined. Sixteen (34%) participants were classified as having epileptic seizure events, and 24 (51%) participants had nonepileptic events. Most participants were Caucasian (87%), female (57%), and unemployed (55%). HIP scores ranged from 0 to 10. Participants classified with nonepileptic scores had higher mean HIP scores (8.08, SD 2.483) than those diagnosed with epileptic seizures [5.94, SD 3.492, t(25)=2.126, P=0.044]. The sensitivity of eliciting a nonepileptic event during hypnosis was only 0.46, but the specificity was 0.88. CONCLUSION Hypnosis may be considered as a method of seizure provocation. Events provoked by hypnotic suggestion were more likely than not to be nonepileptic events. However, the current study has moderate specificity and poor sensitivity. Seizures could not be induced in patients who did not also have spontaneous seizures. Additional methodologies for seizure provocation need to be explored.

Health behaviors and conditions of persons with epilepsy: A bivariate analysis of 2006 BRFSS data ☆

Using amalgamated Behavioral Risk Factor Surveillance System (BRFSS) data from nine states in 2006, this study examined the differences in demographics, health conditions, health behaviors, and quality of life among persons with active epilepsy (PWAE) and persons with a lifetime prevalence of epilepsy (PWLE), compared with persons without epilepsy (PWOE). Frequencies for PWAE, PWLE, and PWOE by selected health behaviors, health conditions, quality of life, and demographic variables were produced. Differences between persons with and without epilepsy were analyzed. Results indicated smoking and unemployment rates were significantly higher among PWLE/PWAE than among PWOE. PWLE/PWAE were also less likely than PWOE to report advanced educational attainment, and more likely to report suffering physical, mental, or emotional limitations that affected their activities in some way. Hispanics were less likely to report a lifetime or active prevalence of epilepsy than people without epilepsy. PWLE/PWAE report several differences in demographics, health conditions, health behaviors, and quality of life compared to people without epilepsy.

Effect of cortical cooling on interictal epileptiform activities

OBJECTIVE To determine if applying chilled solution to exposed cerebral cortex can reduce interictal epileptiform activities in patients during surgery. METHODS Electrocorticography was used to record the epileptiform activity of 12 patients (ages 18-53) undergoing cortical mapping and resection surgery. Interictal spikes were counted at baseline and compared with spikes after applying room temperature and chilled Lactated Ringers or normal saline solution. RESULTS Cortical irrigation with 150-cm(3), chilled (4 degrees C) normal saline solution reduced the mean number of interictal spikes from 11.46 to 4.87 spikes per minute (p=0.04). There was no significant reduction in the epileptic spike frequency when room temperature normal saline was used. CONCLUSION The application of chilled solution directly to the cortex can reduce interictal epileptiform activities, suggesting that seizure potential can be suppressed to avoid evoked seizures during intraoperative surgery.

Comparative prediction of nonepileptic events using MMPI-2 clinical scales, Harris Lingoes subscales, and restructured clinical scales

The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) is a psychological testing tool used to measure psychological and personality constructs. The MMPI-2 has proven helpful in identifying individuals with nonepileptic events/nonepileptic seizures. However, the MMPI-2 has had some updates that enhanced its original scales. The aim of this article was to test the utility of updated MMPI-2 scales in predicting the likelihood of non-epileptic seizures in individuals admitted to an EEG video monitoring unit. We compared sensitivity, specificity, and likelihood ratios of traditional MMPI-2 Clinical Scales against more homogenous MMPI-2 Harris-Lingoes subscales and the newer Restructured Clinical (RC) scales. Our results showed that the Restructured Scales did not show significant improvement over the original Clinical scales. However, one Harris-Lingoes subscale (HL4 of Clinical Scale 3) did show improved predictive utility over the original Clinical scales as well as over the newer Restructured Clinical scales. Our study suggests that the predictive utility of the MMPI-2 can be improved using already existing scales. This is particularly useful for those practitioners who are not invested in switching over to the newly developed MMPI-2 Restructured Form (MMPI-2 RF).
