A Review of Diagnostic Techniques in the Differential Diagnosis of Epileptic and Nonepileptic Seizures 总被引:7,自引:0,他引:7
The diagnosis of psychogenic nonepileptic seizures (PNES) is complex. Long-term electroencephalogram monitoring with video recording (video EEG) is the most common method of differential diagnosis of epilepsy and PNES. However, video EEG is complex, costly, and unavailable in some areas. Thus, alternative diagnostic techniques have been studied in the search for a diagnostic method that is as accurate as video EEG, but more cost effective, convenient, and readily available. This paper reviews the literature regarding possible diagnostic alternatives and organizes findings into 7 areas of study: demographic and medical history variables, seizure semiology, provocative testing, prolactin levels, single photon emission computed tomography, psychological testing, and neuropsychological testing. For each area, the literature is summarized, and conclusions about the accuracy of the technique as a diagnostic tool are drawn. Overall, it appears unlikely that any of the reviewed alternative techniques will replace video EEG monitoring; rather they may be more successful as complementary diagnostic tools. An important focus for further investigations involves combinations of diagnostic techniques for the differential diagnosis of epilepsy and PNES. 相似文献

Visual implicit memory in the left hemisphere: evidence from patients with callosotomies and right occipital lobe lesions 总被引:2,自引:0,他引:2

Identification of visually presented objects and words is facilitated by implicit memory for past visual experiences with those items. Several behavioral and neuroimaging studies suggest that this form of memory is dependent on perceptual processes localized in the right occipital lobe. We tested this claim by examining implicit memory in patients with extensive right occipital lobe lesions, using lexical-decision, mirror-reading, picture-fragment, and word-fragment-completion tests, and found that these patients exhibited normal levels of priming. We also examined implicit memory in patients with complete callosotomies, using standard and divided-visual-field word-fragment-completion procedures, and found that the isolated left hemisphere exhibited normal priming effects. The results indicate that the right occipital lobe does not play a necessary role in visual implicit memory, and that the isolated left hemisphere can support normal levels of visual priming in a variety of tasks. 相似文献

A sample of college students and college athletes completed measures of competitiveness and locus of control. In addition, self-reports of GPA and sex were provided. Negative correlations among scores on competitiveness, GPA, and scores on internal locus of control were significant. Also, there were sex and athletic status differences in competitiveness. 相似文献

To date, little is known about how perceptions of life meaning are formed, although recent evidence suggests that “basic attitudes about the meaning of existence are commonly rooted in evolved biological factors and conjointly influenced through people’s experiences with life” (Steger et al. in J Posit Psychol 6:181–191, 2011a). In line with this view, we proposed that multidimensional aspects of adult attachment security and trait authenticity would independently predict perceptions regarding the presence and search for life meaning. Correlational findings largely supported hypothesized relationships among these variables. Regression findings further demonstrated that adult attachment orientations and trait authenticity uniquely predicted the presence of life meaning, and made more modest contributions to the search for meaning. In both predictions, experiences of self-alienation appeared to function as a mediator of the relationship between attachment security and meaning in life perceptions. Implications of our findings for advancing understanding of the formation of these perceptions are discussed. 相似文献

Background and Objectives: This study examined the relationship between distress tolerance and psychosocial changes among individuals participating in Mindfulness-Based Stress Reduction (MBSR). The objective of the analysis was to discern whether individuals with lower distress tolerance measured before MBSR showed larger reductions in perceived stress following MBSR. Design and Methods: Data were collected from a sample of convenience (n?=?372) using a quasi-experimental design. Participants completed self-report measures immediately prior to course enrollment and following course completion. Results: Perceived stress, distress tolerance, and mood states showed favorable changes from pre- to post-MBSR in the current study. Baseline distress tolerance significantly moderated reductions on perceived stress, supporting the primary hypothesis that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress following MBSR. For a one-unit increase on the self-reported baseline Distress Tolerance Scale, reported perceived stress scores decreased by 2.5 units (p?.0001). Conclusions: The finding that individuals with lower baseline distress tolerance evidenced a greater decline in perceived stress may offer hints about who is most likely to benefit from MBSR and other mindfulness-based treatments. Identifying moderators of treatment outcomes may yield important benefits in matching individuals to treatments that are most likely to work for them. 相似文献

Recent studies suggest that the form of some personality–performance relationships may be curvilinear, meaning that traditional top-down selection is inefficient in capitalizing on underlying personality–performance relationships. This study examines how mean performance is affected by how well the selection method is aligned with the nature of personality–criterion relationships. A simulation manipulated the linearity or nonlinear inflection point of predictor–criterion relationships, and several selection approaches were implemented that varied in level of congruence with these relationships. Results indicate that incongruence can produce notable decrements in mean performance under some conditions. Some evidence also suggests that decrements can be greater when linearity is assumed but relationships are nonlinear (vs. when nonlinearity is assumed but relationships are linear), selection ratios are smaller, and a single predictor is used. 相似文献

Emotional openness is characterised by a capacity to tolerate threatening self-relevant material and an interest towards new emotional situations. We investigated how specific networks of memories could be an important contributing factor to emotional openness. At Phase 1, participants completed measures of personality traits and emotional intelligence, described a self-defining memory, provided other memories associated with it, and rated the valence of each of their memories. A score assessing the complexity of this memory network, comprising the number of memories reported and their valence diversity, was created. Two weeks later, in laboratory, participants watched an anxiety-inducing film and took part in an interview assessing their emotional openness to the film. They completed a cognitive task before and after the film to measure ego depletion. Controlling for traits and emotional intelligence, memory network complexity was positively associated with emotional openness and negatively with ego depletion. The mental organisation of self-defining memories thus appears to be a critical factor contributing to emotional openness. 相似文献

The current study was designed to examine the effect of exposure to muscular ideal bodies on body satisfaction in men. College men (N= 104) at a medium-sized mid-south university completed the Body Assessment (BA)scale, which measures body satisfaction, before and after exposure to either muscular or nonmuscular advertisements. BA scores were examined using a repeated measures (pre and post) ANOVA with muscularity of image (view images of muscular men vs. view images ofaverage men) as the between-participants factor. Results indicated that men’s self-rated body satisfaction decreased after viewing images of muscular men but did not change after viewing images of average men. Thus, it appears that men’s body satisfaction may be influenced by exposure to brief images of muscular models. These results are congruent with results of previous investigations of the effects of viewing images of thin models on women’s body satisfaction. 相似文献
