Carl B. Dodrill 《Epilepsia》1986,27(4):399-411
Relationships between generalized tonic-clonic seizures and indicators of psychological functioning were evaluated in 94 adults with epilepsy who had exceptionally clear seizure histories. Patients were divided according to lifetime numbers of attacks and the presence or absence of a history of major motor status epilepticus. History of status epilepticus or history of more than 100 individual convulsions was associated with decreased functioning in all areas. Abilities were poorest for the group with a history of status, whereas emotional and psychosocial adjustment were worst in persons having large numbers of single convulsions. Possible reasons for the decreased test scores other than seizures were explored in great detail, but none could account for the differences in performance across the groups.  相似文献

Psychosocial Dimensions of Epilepsy: A Review of the Literature   总被引:17,自引:17,他引:2  
The literature on psychosocial dimensions of epilepsy has been reviewed utilizing the framework developed by Dodrill et al. (Epilepsia 1980; 21:123-35). Factors considered were family background, emotional adjustment, interpersonal adjustment, vocational adjustment, financial status, adjustment to seizures, and medicine and medical management. The published studies highlighted a number of issues and sometimes rendered varying and contradictory conclusions. In general, epilepsy fosters certain reactions in family members. If negative, these reactions may be detrimental to the person with epilepsy. The association between specific emotional adjustment factors and epilepsy is not conclusive. Studies have been published which support as well as refute this association. Studies indicate that persons with epilepsy experience lower rates of marriage and more sexual difficulties than do nonepileptic persons. Studies report greater unemployment and underemployment in epileptic persons than in the population at large. Studies suggest that some persons with epilepsy manifest an attitude of nonacceptance of self. Some are reluctant to disclose their disability to others. The studies also indicate the presence of a discriminatory attitude by some nonepileptic persons toward epileptic persons. Several factors are associated with successful medical management of epilepsy. The emphasis in research studies with regard to psychosocial aspects of epilepsy focuses predominantly on individual deficiencies rather than on strengths and abilities.  相似文献

Interictal Behavioral Features of Patients With Epilepsy   总被引:7,自引:7,他引:5  
Summary: Three questions are dealt with in this paper. (1) Do patients with epilepsy differ behaviorally from normal control groups and from persons with other medical and neurological conditions with respect to emotional adjustment, and if so, in what ways? (2) Are patients with temporal lobe epilepsy different emotionally or behaviorally from patients with other types of epilepsy? (3) To what degree does underlying brain dysfunction create a substrate for abnormal and maladaptive behavior? A review of the literature reveals the following. (1) Persons with epilepsy demonstrate more emotional and psychiatric problems than normal individuals and more difficulties than other patient groups having nonneurological disorders, but have about the same incidence of these problems as persons with other neurological disorders. (2) Increased emotional and psychiatric problems are not found among patients with temporal lobe epilepsy in comparison to patients with other types of epilepsy, although there are some behavioral peculiarities which appear in a small proportion of these patients. (3) There is a mild tendency for impairment on neuropsychological tests to be associated with emotional and psychiatric problems in epilepsy.  相似文献

Analysis of face gaze in autism using "Bubbles"   总被引:6,自引:0,他引:6  
One of the components of abnormal social functioning in autism is an impaired ability to direct eye gaze onto other people's faces in social situations. Here, we investigated the relationship between gaze onto the eye and mouth regions of faces, and the visual information that was present within those regions. We used the "Bubbles" method to vary the facial information available on any given trial by revealing only small parts of the face, and measured the eye movements made as participants viewed these stimuli. Compared to ten IQ- and age-matched healthy controls, eight participants with autism showed less fixation specificity to the eyes and mouth, a greater tendency to saccade away from the eyes when information was present in those regions, and abnormal directionality of saccades. The findings provide novel detail to the abnormal way in which people with autism look at faces, an impairment that likely influences all subsequent face processing.  相似文献

The present study investigated whether the human brain is sensitive to valence differences in emotionally negative stimuli by recording event-related potentials (ERPs) for extremely negative (EN), moderately negative (MN), and neutral pictures while subjects perform a standard/deviant categorization task, irrespective of the emotional valence of the deviants. Using the same design, we also investigated the sensitivity of the human brain to valence differences in emotionally positive stimuli. Experiment 1 showed that EN stimuli elicited more negative deflections than MN stimuli in the early P2 and N2, later P3, and slow negative wave (SNW) components. In contrast, there were no differences in amplitude or latency in these components during the extremely positive (EP) and moderately positive (MP) conditions of Experiment 2. This suggests that humans are only sensitive to valence differences in negative stimuli, and that these negative valences could be processed differentially throughout the information processing stream even when individuals are highly engaged in a non-emotional task.  相似文献

BACKGROUND: Oxytocin is known to reduce anxiety and stress in social interactions as well as to modulate approach behavior. Recent studies suggest that the amygdala might be the primary neuronal basis for these effects. METHODS: In a functional magnetic resonance imaging study using a double-blind, placebo-controlled within-subject design, we measured neural responses to fearful, angry, and happy facial expressions after intranasal application of 24 IU oxytocin compared with placebo. RESULTS: Oxytocin reduced right-sided amygdala responses to all three face categories even when the emotional content of the presented face was not evaluated explicitly. Exploratory whole brain analysis revealed modulatory effects in prefrontal and temporal areas as well as in the brainstem. CONCLUSIONS: Results suggest a modulatory role of oxytocin on amygdala responses to facial expressions irrespective of their valence. Reduction of amygdala activity to positive and negative stimuli might reflect reduced uncertainty about the predictive value of a social stimulus and thereby facilitates social approach behavior.  相似文献

Gender differences in the cognitive control of emotion: An fMRI study   总被引:5,自引:1,他引:4  
The interaction of emotion and cognition has become a topic of major interest. However, the influence of gender on the interplay between the two processes, along with its neural correlates have not been fully analysed so far. In this functional magnetic resonance imaging (fMRI) study we induced negative emotion using negative olfactory stimulation while male (n=21) and female (n=19) participants performed an n-back verbal working memory task. Based on findings indicating increased emotional reactivity in women, we expected the female participants to exhibit stronger activation in characteristically emotion-associated areas during the interaction of emotional and cognitive processing in comparison to the male participants. Both groups were found to be significantly impaired in their working memory performance by negative emotion induction. However, fMRI analysis revealed distinct differences in neuronal activation between groups. In men, cognitive performance under negative emotion induction was associated with extended activation patterns in mainly prefrontal and superior parietal regions. In women, the interaction between emotion and working memory yielded a significantly stronger response in the amygdala and the orbitofrontal cortex (OFC) compared to their male counterparts. Our data suggest that in women the interaction of verbal working memory and negative emotion is associated with relative hyperactivation in more emotion-associated areas whereas in men regions commonly regarded as important for cognition and cognitive control are activated. These results provide new insights in gender-specific cerebral mechanisms.  相似文献
