    目的:本研究的目的是探讨急性期认知功能损害与创伤性上肢损伤之间的关系。
    方法:对三组进行了横断面观察性研究:神经损伤组,无神经损伤组,和对照组(未受伤的参与者)。人口特征(如年龄、性别,身体质量指数,和教育)和创伤特征(受伤后的持续时间,受伤的一面,疼痛,轻触感,手运动功能)被记录。使用Rey听觉和言语学习测试(RAVLT)和Stroop颜色和单词测试(SCWT,包括SIECT和SIECN),分别。
    结果:该研究包括神经损伤组的43名参与者,该组30名参与者无神经损伤,和对照组的104名参与者。应用广义线性模型探讨了三组有影响者的认知功能差异。与其他两组相比,神经损伤组的RAVLT表现明显较差,与对照组相比,神经损伤组的SIECT评分较低。然而,3组间SIECN差异无统计学意义。此外,创伤特征对所有受伤参与者的RAVLT和SIECT均无显著影响(p>0.05).
    结论:上肢外伤性神经损伤似乎与短期记忆和执行功能损害有关。而没有神经损伤的肌肉骨骼损伤显示没有认知障碍。因此,监测上肢神经损伤后的认知功能非常重要。
    OBJECTIVE: The purpose of this study was to investigate the association between cognitive impairments and traumatic upper limb injuries of the acute phase.
    METHODS: A cross-sectional observational study was conducted with three groups: a nerve-injury group, a without nerve injury group, and a control group (uninjured participants). Demographic characteristics (e.g. age, sex, body mass index, and education) and traumatic characteristics (duration since injury, injury side, pain, light touch sensation, hand motor function) were recorded. Short-term memory and executive functions were assessed using Rey Auditory and Verbal Learning Test (RAVLT) and Stroop Color and Word Test (SCWT, including SIECT and SIECN), respectively.
    RESULTS: The study comprised 43 participants in the nerve-injury group, 30 participants in the group without nerve injury, and 104 participants in the control group. Generalized linear model was applied to explore the difference of cognitive functions among three groups with impactors. Significantly poorer performance on the RAVLT was observed in the nerve-injury group compared to the other two groups, and lower score of SIECT in nerve-injury group was lower compared to the control group. However, there was no significant difference of SIECN among three groups. In addition, traumatic characteristics did not significantly impact RAVLT and SIECT (p > 0.05) in all injured participants.
    CONCLUSIONS: Traumatic nerve injury to the upper limb appears to be associated with both short-term memory and executive function impairment, whereas musculoskeletal injuries without nerve damage showed no cognitive impairment. Therefore, it is important to monitor cognitive function following upper limb nerve injuries.

    尽管走神(MW)是注意力缺陷和多动障碍(ADHD)的一部分,精神兴奋剂对高分子量的影响尚不清楚.我们旨在阐明精神兴奋剂如何影响成年ADHD患者治疗后的MW。这项横断面队列研究包括54名随机选择的ADHD患者和40名健康对照。ADHD患者给予哌醋甲酯或托莫西汀。半结构化社会人口统计学和临床数据表,成人多动症自我报告量表(ASRS),并应用了精神过度徘徊量表(MEWS)。1日的常规精神病评估,2nd,精神科医生进行了第3个月的药物治疗。ADHD患者治疗前MEWS评分为26.09±1.92,治疗后显著下降至12.78±2.54(F=715.250,p<.001)。平均治疗前ASRS总评分(44.07±10.09)和治疗后评分(27.34±11.22;F=50.364,p<.001)之间存在统计学上的显着差异。终生饮酒/物质使用史与MEWS评分呈正相关。ADHD药物治疗导致MW显著降低。认识到MW和ADHD之间的相互作用可能有助于设计更具体和全面的干预措施。
    Although mind-wandering (MW) is a part of attention deficit and hyperactivity disorder (ADHD), the impact of psychostimulants on excessive MW remains unclear. We aimed to elucidate how psychostimulants impact the MW of adult ADHD patients post treatment. This cross-sectional cohort study consisted of 54 randomly selected ADHD patients who applied to our psychiatry outpatient clinic and 40 healthy controls. The ADHD patients were administered methylphenidate or atomoxetine. A Semi-Structured Sociodemographic and Clinical Data Form, the Adult ADHD Self-Report Scale (ASRS), and the Mind Excessively Wandering Scale (MEWS) were applied. Routine psychiatric assessments in the 1st, 2nd, and 3rd months of pharmacological treatment were carried out by a psychiatrist. The pre-treatment MEWS score of the ADHD patients was 26.09 ± 1.92, which significantly decreased to 12.78 ± 2.54 post-treatment (F = 715.250, p < .001). A statistically significant difference was identified between the mean pre-treatment ASRS total score (44.07 ± 10.09) and post-treatment score (27.34 ± 11.22; F = 50.364, p < .001). A lifetime history of alcohol/substance use was positively associated with the MEWS score. ADHD pharmacotherapy led to significant reductions in MW. Recognizing the interaction between MW and ADHD could help in the design of more specific and comprehensive interventions.

    背景:银屑病和特应性皮炎是世界各地发现的慢性皮肤病,给患者带来很多痛苦。
    目的:这项研究的目的是回答以下问题:患有牛皮癣和AD的人是否在识别情绪方面有更大的问题,注意力和记忆过程的有效性,以及他们是否使用与健康人不同的应对压力的策略。
    方法:本研究涉及90名患者,包括30名牛皮癣患者,30例AD患者和30例健康患者,21至63岁,其中包括54名女性和36名男性。这项研究使用了CANTAB认知测试的电池,迷你COPE问卷清单,多伦多述情障碍量表TAS问卷,银屑病面积和严重程度指数,湿疹面积和严重程度指数。
    结果:银屑病和AD患者的述情障碍量表总分较高,识别和表达情绪的难度更大。患有牛皮癣和AD的人不太可能选择正确的刺激并实现应记住的序列的较短长度。症状更严重的牛皮癣患者在紧张的情况下不太可能使用幽默感的策略。症状更严重的AD患者不太可能使用手术思维策略,否认和自责,寻求工具支持的策略更常用。
    结论:银屑病和AD患者需要整体治疗;除了皮肤病治疗,心理支持,建议提供心理治疗支持和可能的精神病治疗。
    BACKGROUND: Psoriasis and atopic dermatitis are chronic skin diseases found all over the world that cause a lot of suffering to patients.
    OBJECTIVE: The aim of this study was to answer the following questions: whether people suffering from psoriasis and AD have greater problems with recognizing emotions, the effectiveness of attention and memory processes, and whether they use different strategies of coping with stress than healthy people.
    METHODS: This study involved 90 patients, including 30 patients with psoriasis, 30 patients with AD and 30 healthy patients, aged 21 to 63 years, including 54 women and 36 men. This study used a battery of the CANTAB Cognitive Tests, Mini-COPE Questionnaire Inventory, Toronto Alexithymia Scale TAS Questionnaire, Psoriasis Area and Severity Index, and Eczema Area and Severity Index.
    RESULTS: People with psoriasis and AD had higher total scores on the alexithymia scale and had greater difficulty in identifying and verbalizing emotions. People with psoriasis and AD are less likely to choose the correct stimulus and achieve a shorter length of the sequence that should be remembered. Psoriasis patients with more severe symptoms are less likely to use the strategy of a sense of humor in stressful situations. AD patients with more severe symptoms are less likely to use strategies of operative thinking, denial and self-blame, and the strategy of seeking instrumental support is used more often.
    CONCLUSIONS: Patients with psoriasis and AD require a holistic approach; in addition to dermatological treatment, psychological support, psychotherapeutic support and possible psychiatric treatment are recommended.

    疲劳是多发性硬化症(PwMS)患者中极为常见的症状,对生活质量有严重影响。本研究的目的是验证PwMS中的疲劳是否与选择性隐性注意障碍有关,通过事件相关电位进行测量,并评估其是否与自上而下或自下而上的注意力控制受损更相关。22个PwMS和疲劳MSF,17名没有疲劳的MSnF和35名健康志愿者接受了三刺激P300新颖性任务,该任务同时引发了P3a和P3b成分。P3b潜伏期在组间具有可比性,但是PwMS,与疲劳的存在无关,显示出明显更大的P3b振幅。单独MSF的P3a潜伏期明显延长,MSnF组P3a波幅大于对照组。无国界医生能够对与任务相关的目标刺激进行分类,但对新的显着刺激的定向反应被延迟,表明与腹侧注意网络相关的自下而上注意控制机制受损。疲劳选择性地与隐蔽的注意力缺陷有关,该缺陷与将注意力资源重新分配给显着刺激的能力有关,适应性决策行为的一个关键功能。
    Fatigue is an extremely common symptom in in people with multiple sclerosis (PwMS) and has a severe impact on quality of life. The purpose of the present study was to verify whether fatigue in PwMS is associated with a selective covert attention impairment, as measured by event-related potentials and to assess whether it is more associated with an impairment of top-down or bottom-up attentional control. Twenty-two PwMS and fatigue-MSF, 17 without fatigue-MSnF and 35 healthy volunteers underwent a three-stimulus P300 novelty task that elicits both the P3a and the P3b components. P3b latency was comparable between groups, but PwMS, independently from the presence of fatigue displayed significantly greater P3b amplitudes. P3a latency was significantly prolonged in MSF alone, while P3a amplitude in MSnF group was greater than controls. MSF were able to categorize the task-relevant target stimulus but the orienting response to a novel salient stimulus was delayed, indicating an impairment in bottom-up attentional control mechanism related to ventral attention network. Fatigue is selectively associated with a covert attentional deficit related to the ability to reallocate attentional resources to salient stimuli, a crucial function of adaptive decision-making behaviour.

    预测处理(PP)是神经科学中的主要理论框架。虽然已经做出了一些努力来在认知领域-一般网络视角下构建PP,暗示“预测网络”的存在,“这些研究主要集中在特定的认知领域或功能。是否存在包含所有完善的认知域的通用域预测网络的问题仍然没有答案。本荟萃分析旨在通过测试PP依赖于跨越认知领域的大规模网络的假设来解决这一差距。支持PP作为一个统一的账户,朝着神经科学的更综合的方法发展。采用激活似然估计元分析方法,连同元分析连接图,连接分析,和行为解码技术。分析的重点是预测不一致和预测一致性,两个条件可能反映PP的核心现象。此外,分析集中在与预测现象无关的维度上,无论预测不一致和一致性如何。这些分析首先应用于所考虑的每个认知领域(认知控制,注意,电机,语言,社会认知)。然后,所有的认知领域都被折叠成一个单一的,跨域维度,总共包含252个实验。与预测不一致有关的结果依赖于跨认知领域的定义网络,而预测一致性结果显示总体激活较少,认知领域的变异性略大。跨预测现象和认知领域的激活的收敛模式突出了在有组织的大规模网络(动态预测网络)中几个大脑中心展开的作用。主要包括双侧脑岛,额叶回旋,claustrum,顶叶小叶,和颞回。此外,在跨域中发挥的关键作用,前岛多模态水平,正如连接和元分析连接图分析所证明的那样,将其作为动态预测网络的主要枢纽。结果支持PP依赖于领域通用的假设,PP单元可能在其区域内运行的大型网络,取决于环境和环境需求。动态预测网络中的广泛区域无缝集成了依赖于上下文和刺激的预测计算,从而有助于大脑内在和外在世界模型的适应性更新。
    Predictive processing (PP) stands as a predominant theoretical framework in neuroscience. While some efforts have been made to frame PP within a cognitive domain-general network perspective, suggesting the existence of a \"prediction network,\" these studies have primarily focused on specific cognitive domains or functions. The question of whether a domain-general predictive network that encompasses all well-established cognitive domains exists remains unanswered. The present meta-analysis aims to address this gap by testing the hypothesis that PP relies on a large-scale network spanning across cognitive domains, supporting PP as a unified account toward a more integrated approach to neuroscience. The Activation Likelihood Estimation meta-analytic approach was employed, along with Meta-Analytic Connectivity Mapping, conjunction analysis, and behavioral decoding techniques. The analyses focused on prediction incongruency and prediction congruency, two conditions likely reflective of core phenomena of PP. Additionally, the analysis focused on a prediction phenomena-independent dimension, regardless of prediction incongruency and congruency. These analyses were first applied to each cognitive domain considered (cognitive control, attention, motor, language, social cognition). Then, all cognitive domains were collapsed into a single, cross-domain dimension, encompassing a total of 252 experiments. Results pertaining to prediction incongruency rely on a defined network across cognitive domains, while prediction congruency results exhibited less overall activation and slightly more variability across cognitive domains. The converging patterns of activation across prediction phenomena and cognitive domains highlight the role of several brain hubs unfolding within an organized large-scale network (Dynamic Prediction Network), mainly encompassing bilateral insula, frontal gyri, claustrum, parietal lobules, and temporal gyri. Additionally, the crucial role played at a cross-domain, multimodal level by the anterior insula, as evidenced by the conjunction and Meta-Analytic Connectivity Mapping analyses, places it as the major hub of the Dynamic Prediction Network. Results support the hypothesis that PP relies on a domain-general, large-scale network within whose regions PP units are likely to operate, depending on the context and environmental demands. The wide array of regions within the Dynamic Prediction Network seamlessly integrate context- and stimulus-dependent predictive computations, thereby contributing to the adaptive updating of the brain\'s models of the inner and external world.

    介绍双相情感障碍和精神分裂症表现出不同的认知障碍模式,精神分裂症在言语记忆和社会认知方面表现出更深刻的缺陷。了解这些模式可能会指导干预措施的发展,以增强对这些疾病的认知。目的本研究旨在评估和比较被诊断为双相情感障碍和精神分裂症的人的认知能力。方法2016年12月至2017年6月,在30名18-45岁的精神分裂症和30名双相情感障碍患者中进行了一项基于设施的横断面研究。在通过汉密尔顿抑郁量表(HDRS)筛查后选择的缓解中,青年躁狂症评定量表(YMRS),或阳性和阴性综合征量表(PANSS)。排除包括分裂情感障碍,全身性疾病,大脑/神经疾病,和药物滥用。收集选定患者的基线人口统计学和临床资料后,对认知领域进行了评估,如注意力(手指跨度),言语记忆(Rey的听觉言语学习测试(RAVLT)),视觉记忆(ReyComplexFigure),语言流利(动物命名),和执行功能(Stroop和跟踪制作)。使用IBMSPSSStatisticsforWindows分析数据,版本16(2007年发布;IBMCorp.,Armonk,纽约,美国)使用标准的描述性和推断性统计数据。结果两组间的社会人口统计学和临床特征基本相似。精神分裂症患者的注意力较差,工作记忆,与双相情感障碍患者相比,视觉注意力/任务切换。双相患者在这些领域表现出相对保留的能力,但在视觉和言语记忆方面表现出更多的障碍。独特的模式突出了独特的神经生物学基础,显示精神分裂症中更广泛的认知缺陷和双相情感障碍中更局部的记忆功能损害。结论研究结果解释了这些疾病独特的神经生物学机制,并可能有助于开发有针对性的认知修复和药物干预措施,以改善功能结果和生活质量。
    Introduction Bipolar disorder and schizophrenia exhibit different patterns of cognitive impairment, with schizophrenia demonstrating more profound deficiencies in verbal memory and bipolar disorder in social cognition. Understanding these patterns may guide the development of interventions to enhance cognition in these disorders. Aim This study aims to assess and compare the cognitive abilities of persons diagnosed with bipolar illness and schizophrenia. Methodology A facility-based cross-sectional study was done from December 2016 to June 2017 among 30 schizophrenia and 30 bipolar disorder patients aged 18-45 years, in remission selected after screening through Hamilton Depression Rating Scale (HDRS), Young Mania Rating Scale (YMRS), or Positive and Negative Syndrome Scale (PANSS). Exclusions included schizoaffective disorder, systemic illness, brain/neurological conditions, and substance abuse. After collecting the baseline demographic and clinical profile of the selected patients, the cognitive domains were assessed such as attention (digit span), verbal memory (Rey\'s Auditory Verbal Learning Test (RAVLT)), visual memory (Rey Complex Figure), verbal fluency (Animal Naming), and executive functions (Stroop and Trail Making). The data was analyzed using the IBM SPSS Statistics for Windows, Version 16 (Released 2007; IBM Corp., Armonk, New York, United States) using standard descriptive and inferential statistics. Results Sociodemographic and clinical characteristics were largely similar between groups. Schizophrenia patients showed poorer attention, working memory, and visual attention/task-switching compared to bipolar patients. Bipolar patients demonstrated relatively preserved abilities in these domains but exhibited more impairments in visual and verbal memory. Distinct patterns highlight unique neurobiological underpinnings, showing association of more generalized cognitive deficits in schizophrenia and more localized impairments in memory functions in bipolar disorder. Conclusion The study findings explain these disorders\' unique neurobiological mechanisms and may help develop targeted cognitive remediation and pharmacological interventions to improve functional outcomes and quality of life.

    认知障碍是精神分裂症的核心特征之一,涉及神经认知和社会认知领域,并对现实世界的运作产生重大负面影响。本综述为精神分裂症中“原发性”和“继发性”认知障碍的概念化和表征提供了框架。在这个概念中,原发性认知障碍可以定义为神经生物学改变的结果,该神经生物学改变是该疾病的精神病理学表现的基础,而继发性认知障碍可以定义为对认知表现有负面影响的来源问题的结果。继发性认知障碍的来源在精神分裂症患者中很常见,包括几个不同的因素,如阳性和阴性症状,抑郁症状,自闭症症状,药物治疗,药物滥用,代谢综合征,社会剥夺,和睡眠障碍。可以假设继发性认知障碍可以通过有效解决来源问题来改善。而原发性认知障碍可能受益于专门治疗。需要进一步的研究来证实这一假设,为了在临床和神经生物学角度更好地描述原发性和继发性认知障碍之间的区别,并评估系统评估和治疗继发性认知障碍的影响。
    Cognitive impairment represents one of the core features of schizophrenia, involves both neurocognition and social cognition domains, and has a significant negative impact on real-world functioning. The present review provides a framework for the conceptualization and characterization of \"primary\" and \"secondary\" cognitive impairment in schizophrenia. In this conceptualization, primary cognitive impairment can be defined as a consequence of the neurobiological alterations that underlie psychopathological manifestations of the disorder, while secondary cognitive impairment can be defined as the results of a source issue that has a negative impact on cognitive performance. Sources of secondary cognitive impairment are frequent in people with schizophrenia and include several different factors, such as positive and negative symptoms, depressive symptoms, autistic symptoms, pharmacotherapy, substance abuse, metabolic syndrome, social deprivation, and sleep disorders. It can be hypothesized that secondary cognitive impairment may be improved by effectively resolving the source issue, while primary cognitive impairment may benefit from dedicated treatment. Further research is required to confirm this hypothesis, to better characterize the distinction between primary and secondary cognitive impairment in a clinical and in a neurobiological perspective, and to evaluate the impact of systematically assessing and treating secondary cognitive impairment.

    这项研究调查了与其他复杂学习活动相比,语言学习对认知健康的认知功能和社会心理健康的影响,社区居住的老年人。在一项随机对照试验中,43名65-78岁的荷兰语功能单一语言者完成了为期三个月的英语课程(n=15),音乐训练(n=13),或系列讲座(n=15)。认知功能(全球认知,认知灵活性,情景记忆,工作记忆,口语流利,和注意力)和社会心理健康在干预之前和之后立即进行评估,在四个月的随访中。语言学习者在情景记忆和认知灵活性方面有显著提高。然而,语言学习和音乐训练条件之间的认知变化幅度没有显着差异,除了从预测到随访,语言学习者的认知灵活性发生了较大的积极变化。我们的结果表明,在以后的生活中学习语言可以提高一些认知功能和额外语言的流畅性,但其独特的效果似乎有限。
    This study investigated the impact of language learning in comparison to other complex learning activities on cognitive functioning and psychosocial well-being in cognitively healthy, community-dwelling older adults. In a randomized controlled trial, 43 Dutch functionally monolinguals aged 65-78 completed a three-month English course (n = 15), music training (n = 13), or a lecture series (n = 15). Cognitive functioning (global cognition, cognitive flexibility, episodic memory, working memory, verbal fluency, and attention) and psychosocial well-being were assessed before and immediately after the intervention, and at a four-month follow-up. The language learners significantly improved on episodic memory and cognitive flexibility. However, the magnitude of cognitive change did not significantly differ between the language learning and music training conditions, except for a larger positive change in cognitive flexibility for the language learners from pretest to follow-up. Our results suggest that language learning in later life can improve some cognitive functions and fluency in the additional language, but that its unique effects seem limited.
