自精神病学纳入医学的范畴之后,精神疾病的诊断因为其所声称的科学手段而被认为是科学的判断。20世纪中叶开始的反精神病学运动全面否定其科学性,认为精神疾病的诊断是单纯的伦理价值判断。两种观点都显得过于极端。精神疾病的特殊性决定了精神疾病的诊断是科学判断基础上的伦理判断。其中科学的判断不是决定性的,而是基础性的。决定性的是伦理的判断,只是这种伦理判断必须建立在科学判断的基础之上而已。  相似文献

ABSTRACT

Sickle cell disease (SCD), an inherited blood disorder that primarily affects individuals of African descent, is associated with serious medical complications as well as numerous social-environmental risk factors. These social-environmental factors are linked to long-standing social inequities, such as financial hardship and racial discrimination, both of which impact cognitive and behavioral functioning in youth. Previous research on the relationship between social-environmental risk and psychological functioning has primarily relied on non-modifiable, unidimensional measures of socioeconomic status (SES), such as income and parental education, as a proxy for social-environmental risk. The current study aimed to address the limitations associated with typical SES-type measures by comparing the unique and shared association of SES and more targeted and modifiable social-environmental factors (e.g., parent and family functioning) with specific areas of cognitive and behavioral adjustment in pediatric SCD. Seventy children ages 4–8 years old and their parents completed measures of social-environmental risk and psychological adjustment. Exploratory factor analysis indicated parent and family functioning measures were largely independent of SES. Parent and family functioning predicted phonological processing and ADHD symptoms above and beyond SES alone. In addition, the predictive ability of social-environmental risk factors appears to vary by genotype severity for measures of social functioning and math problem-solving ability. Future studies are needed to explore more specific and well-supported models of modifiable social-environmental risk and the relative impact of social-environmental risk on cognitive and behavioral functioning.  相似文献

The human experience of survival from a plague is about distinguishing the sick from the healthy as quickly as possible, establishing a barrier to stop the infection, and protecting healthy people. Nevertheless, the various quarantine rules and the acceptance and compliance of the population are a kind of battle between policy implementers and the public. This paper tries to understand how Chinese cultural attitudes (Henderson, 1984) unconsciously influence the Chinese people to be most cooperative with the strict containment and quarantine measures to confront the COVID-19 pandemic. This article begins with the Chinese characters, exemplified by the four characters of disease and plague, to discuss how the pictograph nature and spatial structural way profoundly shaped the cultural mind. Then, through plague-related Chinese legends, stories and folklore, the paper sets out the Chinese cultural attitudes which are also manifested in the analogical associations between disease, plague and seasons, the balance of the five elements of the universe and ghosts, gods and the government bureaucrats in the Kingdom of the Heaven. All of these approaches are well in line with Jung’s method of associative amplification as a way to locate the archetypal wisdom that assures survival.  相似文献

Prior work on patients with Parkinson's disease (PD) has shown that the administration of dopaminergic medication in the early to intermediate stages of PD benefits (motor) functions associated with the dopamine-depleted dorsal striatal circuitry but may ‘overdose’ and interfere with (cognitive) functions associated with the relatively intact ventral striatal circuitry. The present study aimed to elucidate this so-called dopamine overdose hypothesis for the action control domain. Using a within-subject design in a sample of 13 people with PD, we evaluated the effect of dopaminergic medication on two cognitive processes underlying goal-directed behaviour, namely action selection and initiation through event binding and conflict adaptation. We also investigated whether individual differences in the magnitude of medication effects were associated across these processes. Results showed no indications that dopaminergic medication affects action selection and initiation or conflict adaptation in PD patients. Additionally, we observed no correlations between both cognitive processes nor between individual differences in medication effects. Our findings do not support the notion that dopaminergic medication modulates action control processes, suggesting that the dopamine overdose hypothesis may only apply to a specific set of cognitive processes and should potentially be refined.  相似文献

Working memory (WM) impairments are reported to occur in patients with Parkinson's disease (PD). However, the mechanisms are unclear. Here, we investigate several putative factors that might drive poor performance, by examining the precision of recall, the order in which items are recalled and whether memories are corrupted by random guessing (attentional lapses). We used two separate tasks that examined the quality of WM recall under different loads and retention periods, as well as a traditional digit span test. Firstly, on a simple measure of WM recall, where patients were asked to reproduce the orientation of a centrally presented arrow, overall recall was not significantly impaired. However, there was some evidence for increased guessing (attentional lapses). On a new analogue version of the Corsi-span task, where participants had to reproduce on a touchscreen the exact spatial pattern of presented stimuli in the order and locations in which they appeared, there was a reduction in the precision of spatial WM at higher loads. This deficit was due to misremembering item order. At the highest load, there was reduced recall precision, whereas increased guessing was only observed at intermediate set sizes. Finally, PD patients had impaired backward, but not forward, digit spans. Overall, these results reveal the task- and load-dependent nature of WM deficits in PD. On simple low-load tasks, attentional lapses predominate, whereas at higher loads, in the spatial domain, the corruption of mnemonic information—both order item and precision—emerge as the main driver of impairment.  相似文献

Here, we examined mechanisms that affect retrograde memory in amnestic mild cognitive impairment (a-MCI) as a function of longitudinal clinical outcome. 8 a-MCI who converted to Alzheimer's dementia (AD) during the subsequent 3-year follow-up (converter a-MCI) and 10 a-MCI who remained clinically stable during the same period (stable a-MCI) were compared at the baseline evaluation (i.e., when they were diagnosed as a-MCI) using a remote memory questionnaire for public events that allows disentangling the differential contribution of storage and retrieval mechanisms to performance accuracy. Results suggest that deficits in remote memory are primarily explained by impaired retrieval abilities in stable a-MCI and by impaired storage in converter-to-AD a-MCI. This distinction between retrograde amnesia due to defective trace utilisation in stable a-MCI and trace storage in converter a-MCI is consistent with the temporal unfolding of declining anterograde memory over the course of disease progression to AD.  相似文献

Affective touch is gentle slow stroking of the skin, which can reduce experimentally induced pain. Our participant, suffering from Parkinson's Disease and chronic pain, received 1 week of non-affective touch and 1 week of affective touch as part of a larger study. Interestingly, after 2 days of receiving affective touch, the participant started to feel less pain. After 7 days, the burning painful sensations fully disappeared. This suggest that affective touch may reduce chronic pain in clinical populations.  相似文献

IntroductionCrohn's disease (CD), a chronic inflammatory bowel disease, has strong psychological and social repercussions related to the specificity of the symptomatology. To better understand how patients cope with the disease, coping strategies have been studied but without taking into account the specificity of the CD experience.ObjectiveOur objective is to identify the perceived coping strategies used by patients in relation to their illness experience.MethodUsing a qualitative approach, semi-structured interviews and thematic content analysis with 33 CD patients in remission were conducted.ResultsOur results highlight that some of the coping strategies used are not taken into account by the coping scales frequently used in the literature. Indeed, the illness experience appears to be fundamental in the establishment of new strategies based on the experiential knowledge patients use to reduce the stress induced by a potential relapse. Moreover, coping strategies based on positive emotions are also implemented, and they enable patients to make sense of the disease.ConclusionThe coping strategies, i.e., “experiential knowledge” and “positive emotions”, may shed more light on the complexity of the illness experience of CD patients and allow us to make recommendations concerning the psychological support of patients.  相似文献
