ABSTRACT

Introduction

Individuals with autism spectrum disorder (ASD) and intellectual disability (ID) seem to be at increased risk for post-traumatic stress disorder (PTSD), but knowledge is sparse regarding its identification in this population. Previous research indicates that certain symptoms of PTSD may be more easily recognized, and that identifying reexperiencing and avoidance is particularly challenging.  相似文献

Objectives

This paper introduces some epistemology about mental health developments and how it leads to reconsider the landscape of clinical practices.

Materials

From an epistemological point of view, the author reviews several writings about mental hygiene going back to the nineteenth century. It clarifies the common roots between mental hygiene and mental health. Then, the article examines the first World Health Organization's reports, that shed light on psychiatric and political issues in the middle of the twentieth century, which allows to reach out the foundations of mental health as a discursive practice.

Results

The review of the developments from “mental hygiene” to “mental health” highlights a general climate of redesign on many points: Mental health as a discursive space is characterized by an expansion of its address field. It is not only addressed to specialists, psychiatrist and psychiatric patients, but also, and above all, to every citizen. Psychic suffering, as far as mental illness, is part of a larger whole including what preserves or deteriorates the proper functioning of an individual, within society. Mental health is at the crossroads of financial, political, citizen's rights and social interests. Contemporary mental health relies on the objectives of prevention and promotion. Clinical practices are organized by some discourses with mental health as a key word. At the turn of 2000s, French psychiatry has been impacted by many shuffles in health policies. However, the roots of these restructuring are not new, as they update an old interest in safeguarding public health, funds and welfare. Psychic suffering and mental illness recently enter the field of “psychic disability”. It brought social benefits such as financial assistance from the state. It may also contribute to the campaigns of awareness-raising and destigmatization among the public opinion. However, financial and subjective effects do not perfectly match. In other words, the benefits listed above should not lead to desert the listening of the users’ experience in its singularity.

Conclusions

The developments of mental health point out a reorganization in the psychiatric field and open new clinical challenges. If the spaces of singularity and universal are in a permanent relationship, the political and economic sides cannot answer or evacuate the subjectivity posed by the subject and his suffering. It should lead to focus on a clinical practice driven by a subtle listening, which does not exclude psychopathology and recognizes the importance of alterity.  相似文献

Predictors of gastric emptying (GE) in patients with idiopathic Parkinson's disease (PD) of a solid and liquid meal are not well defined. For measurement of GE 80 patients with PD were randomly assigned to receive either a solid meal (250 kcal) containing 13C-octanoate (n = 40) or a liquid meal (315 kcal) with 13C-acetate (n = 40). All patient groups were off medication affecting motility and were matched for age, gender, body mass index, disease duration and severity, using Unified Parkinson's Disease Rating Scale (UPDRS). Gastric emptying was compared with a healthy control group (n = 40). Multiple regression analysis was used to determine predictors of gastric emptying. Exactly 88% and 38% of PD patients had delayed GE of solids and liquids respectively. Solid and liquid emptying was similar in women and men. There were no differences in GE in PD patients < 65 years of age when compared with patients > or = 65 years. Multiple regression analysis showed that motor handicaps such as rigour and action tremor are independent predictors of solid GE (r = 0.68, P < 0.001). The severity of motor impairment, but not any other neurological symptom, as assessed by UPDRS is associated with gastroparesis in PD and solid emptying is more likely to be delayed.  相似文献

Multiple regression analysis of twin data obtained from selected samples   总被引:3,自引:0,他引:3  
The multiple regression analysis of twin data in which a cotwin's score is predicted from that of a proband (the member of a twin pair selected because of a deviant score) and the coefficient of relationship provides a powerful test of genetic etiology (DeFries and Fulker: Behav Genet 15:467-473, 1985). Moreover, when an augmented model containing an interaction term is fitted to the same data set, direct estimates of heritability (h2) and the proportion of variance owing to shared environmental influences (c2) are also obtained. In the present paper, the expected partial regression coefficients estimated from these models are derived, and the flexibility of the general approach is illustrated. An extended model is formulated for the analysis of data from combined samples of affected and control twin pairs that yields tests for differential h2 and c2 in the two groups as well as pooled estimates of these parameters. The application of these models is illustrated by an analysis of data from reading-disabled and control twin pairs. Because of the ease, flexibility, and utility of the multiple regression analysis of twin data, it is an appealing alternative to more traditional model-fitting approaches.  相似文献

Objectives –  To assess long‐term functioning and disability after traumatic brain injury (TBI). Material and methods –  Individuals (n = 88) in Norrbotten, northern Sweden, who had been transferred for neurosurgical care were assessed with internationally established TBI outcome measures 6–15 years post‐injury. Results –  There was an improvement in overall outcome from discharge from inpatient rehabilitation to follow‐up. Many individuals had a high degree of motor and cognitive functioning, which enabled them to live independently in their own home without assistance, but there remained a disability related to community reintegration and social participation. This affected their productivity and to some degree their marital stability. The remaining disability and reduced productivity were related to the age at injury and the injury severity. Conclusions –  Our data showed that individuals with a TBI can achieve and maintain a high degree of functioning many years after the injury. Increasing age and a greater injury severity contributed to their long‐term disability.  相似文献

目的 了解精神病人和正常人戒烟前后精神状况的变化及差异性 ,探讨戒烟措施。方法 对 71例精神病人和 5 0例正常人戒烟前及戒烟后 1周分别应用汉密顿焦虑量表 (HAMA)、汉密顿抑郁量表 (HAMD)、焦虑自评量表 (SAS)、抑郁自评量表 (SDS)、简明精神病量表 (BPRS )进行测评。结果 精神病人强制性戒烟前HAMA、HAMD、SAS、SDS、BPRS分值分别为 (8.2 1± 6 .4 1)、(7.6 4± 5 .71)、(36 .81± 7.14 )、(33.71± 7.1)、(2 9.4 5± 8.4 7) ;戒烟后HAMA、HAMD、SAS、SDS、BPRS分值分别为 (16 .4 5± 6 .34)、(19.73± 8.71)、(5 8.1± 12 .12 )、(5 6 .31± 11.4 )、(37.32± 7.95 ) ;戒烟前后 5种量表分值变化与正常人戒烟前后分值变化比较有极显著性差异(P <0 .0 1)。结论 对精神病人强制性戒烟可引起明显的情绪反应 ,应适宜控制病人吸烟 ,建立一个合理的管理制度  相似文献

The most spectacular contribution from the nordic countries to intellectual disability policy is probably the idea of normalization, but it is not the simplistic notion that can be inferred from international debate. Its major significance may have been to act as an inspiring catchword for the important trend away from institutions Into integrated living. However, it is more fully understood when seen in the concrete context where It has successively developed, and been critically analysed and tested in operation. Scandinavian sociologists and psychologists—as well as politicians—were also among the first to use the concept of quality of life for analysis of social policy, including intellectual disability. The primary medium for implementation has been legislation, where the dominant difficulty is to find a balance between security and freedom, protection and self-determination. Through this process, the role of social engineering in the welfare state, based on humanistic ideas of solidarity, can be followed into today's emphasis on individual influence and participation.  相似文献

The recovery of the ability to read of a patient affected by persistent visuospatial neglect suggests the functional independence of the two phenomena. Neglect dyslexia seems to be an example of a dissociation between an implicit and explicit knowledge of the characteristics of the stimulus.
Sommario Il recupero della capacità di lettura in un paziente con persistente neglect visuo-spaziale suggerisce l'indipendenza funzionale dei due fenomeni. La neglect dyslexia sembra costituire un esempio di dissociazione tra conoscenza implicita ed esplicita delle caratteristiche dello stimolo.
