Background: Anhedonic features within major depressive disorder (MDD) have been associated with worse course and outcome and may predict non-response to treatment. However a detailed clinical profile of anhedonia in MDD is still lacking.

Materials and methods: One thousand two hundred ninety-four patients with MDD were selected from the cross-sectional European multicenter Group for the Study of Resistant Depression (GSRD) study. Anhedonia was assessed through the Montgomery-Åsberg Depression Rating Scale anhedonia item "inability to feel". Clinical and demographic features were then analyzed.

Results: The presence of anhedonia related to a distinct demographical (living alone) and clinical profile (thyroid diseases, diabetes, suicide risk, high number of previous depressive episodes, more severe MDD and more frequent inpatients status). Furthermore, anhedonia was associated with non-response to treatment and treatment resistance, even after adjusting for confounding variables.

Conclusion: Our findings support the role of anhedonia as a modulating feature of MDD, being associated with a more severe depression profile. Moreover, anhedonic features are independent predictors of poor treatment response.

背景:重度抑郁障碍(MDD)中的失乐症特征与较差的病程和预后有关,并可能预示着对治疗的不反应。然而,目前仍缺乏关于重度抑郁症患者厌世特征的详细临床资料:从欧洲多中心抗药性抑郁症研究小组(GSRD)的横断面研究中选取了1294名MDD患者。厌世情绪通过蒙哥马利-奥斯伯格抑郁量表厌世情绪项目 "无法感受 "进行评估。然后对临床和人口统计学特征进行了分析:结果:失乐症的存在与独特的人口统计学特征(独居)和临床特征(甲状腺疾病、糖尿病、自杀风险、既往抑郁发作次数多、更严重的 MDD 和更频繁的住院状态)有关。此外,即使在调整了混杂变量后,失乐症仍与治疗无反应和治疗抵抗有关:我们的研究结果表明,失乐症是多发性抑郁症的一种调节特征,与更严重的抑郁症特征相关。此外,失乐症特征是治疗反应不佳的独立预测因素。

Background: Postoperative cognitive dysfunction (POCD) is a common neurological complication in older patients and correlated with adverse outcomes.17β-estradiol treatment was reported to provide neuroprotective protection in various neurologic disorders, but whether it attenuated POCD was unknown. The purpose of this study was to explore the effects of 17β-estradiol treatment on POCD and the mechanisms.

Methods: We generated a POCD model in 15-month-old mice via laparotomy, followed by subcutaneous injection of 17β-estradiol, intraperitoneal injection of EX527 (a SIRT1 inhibitor) or bilateral hippocampal injection of miR-138-5p-agomir. Morris water maze test and open field test were applied to evaluate the cognitive function. The neuronal apoptosis in hippocampus was detected using TUNEL assay. Meanwhile, the levels of IL-1β and microglia activation were measured by ELISA and immunofluorescence, respectively. Western blot was utilized to assess the expression of SIRT1 and HMGB1 protein, and gene expression of miR-138-5p was determined through qRT-PCR.

Results: Behavioral tests showed that 17β-estradiol treatment improved cognitive function in aged POCD mice. In addition, 17β-estradiol attenuated neuronal apoptosis and microglia activation as well as IL-1β expression in hippocampus. Nonetheless, injection with EX527 abolished the beneficial impacts of 17β-estradiol against POCD. Furthermore, miR-138-5p was verified to bind with SIRT1, which regulated the expression of HMGB1. After treatment with 17β-estradiol, miR-138-5p expression was reduced in hippocampus, and the neuroprotective influence of 17β-estradiol on aged POCD mice was reversed after administration of miR-138-5p-agomir.

Conclusions: 17β-estradiol treatment exerted neuroprotection effects on POCD in aged mice, which might be relevant to alleviating neuroinflammation via miR-138-5p/SIRT1/HMGB1 pathway.

背景:据报道,17β-雌二醇治疗对各种神经系统疾病具有神经保护作用,但其是否能减轻POCD尚不清楚。本研究旨在探讨17β-雌二醇治疗对POCD的影响及其机制:方法:我们在15月龄的小鼠中通过开腹手术建立了一个POCD模型,然后皮下注射17β-雌二醇、腹腔注射EX527(一种SIRT1抑制剂)或双侧海马注射miR-138-5p-agomir。实验采用莫里斯水迷宫测试和开阔地测试评估认知功能。用TUNEL检测海马神经元凋亡。同时,分别用ELISA和免疫荧光法测定IL-1β和小胶质细胞的活化水平。利用 Western blot 评估 SIRT1 和 HMGB1 蛋白的表达,并通过 qRT-PCR 测定 miR-138-5p 的基因表达:行为测试表明,17β-雌二醇治疗可改善老年 POCD 小鼠的认知功能。此外,17β-雌二醇还能减轻海马中神经元凋亡、小胶质细胞活化以及 IL-1β 的表达。然而,注射 EX527 后,17β-雌二醇对 POCD 的有益影响消失了。此外,miR-138-5p 被证实与 SIRT1 结合,从而调节 HMGB1 的表达。用17β-雌二醇治疗后,miR-138-5p在海马中的表达减少,而在服用miR-138-5p-agomir后,17β-雌二醇对老年POCD小鼠神经保护作用的影响被逆转:结论:17β-雌二醇治疗对老年 POCD 小鼠具有神经保护作用,这可能与通过 miR-138-5p/SIRT1/HMGB1 通路缓解神经炎症有关。

Background: While esketamine is effective in treatment-resistant depression (TRD), detailed information about the effect of esketamine on cognition is relatively scarce. This analysis assessed the effect of short-term (three double-blind [DB] studies; DB1, DB2, and DB4) or long-term maintenance treatment (DB3) with esketamine nasal spray (ESK) compared to an active-comparator+placebo (PBO), on cognition in patients with TRD.

Methods: Patients (DB1/DB2/DB3: [18-64years, n=747]; DB4: [≥65years, n=137]) with TRD received ESK (DB1/DB2/DB3:56/84mg; DB4:28/56/84mg) or PBO+newly initiated oral antidepressant (OAD) as per treatment schedules. Cognitive assessments- Cogstate battery and Hopkins Verbal Learning Test-Revised, were administered at baseline, Day-28/early withdrawal, and follow-up visits in DB1/DB2/DB4 and at 12-week intervals in DB3 maintenance phase. Descriptive statistics were used to analyze ESK effects on cognition with effect sizes and 95% confidence intervals (CIs) used to express the nature/magnitude of treatment effects relative to active-comparator+PBO. Correlation between depression severity (MADRS scores) and cognition was assessed at baseline and endpoint(s).

Results: At baseline, mild-to-moderate impairment in psychomotor function, attention, and memory (working/episodic) were evident. For each DB1/DB2/DB4, group mean performance in z-scores for ESK+OAD and OAD+PBO groups on all cognitive tests remained similar/slightly improved from, baseline at endpoint (Day-28) and follow-up assessments. Similarly, in DB3(limited to participants ≥65years), both groups generally showed improvement in cognitive performance at endpoint(s). Correlations between MADRS scores and performance on the cognitive test battery were small at baseline and endpoint(s).

Conclusion: This analysis did not identify evidence of negative effects on cognition following short-term or long-term maintenance treatment with ESK+OAD in patients with TRD.

背景:虽然埃斯氯胺酮对治疗耐受性抑郁症(TRD)有效,但有关埃斯氯胺酮对认知影响的详细信息却相对较少。本分析评估了埃斯氯胺酮鼻喷雾剂(ESK)短期(三项双盲[DB]研究:DB1、DB2和DB4)或长期维持治疗(DB3)与活性比较剂+安慰剂(PBO)相比,对TRD患者认知能力的影响:TRD患者(DB1/DB2/DB3:[18-64岁,n=747];DB4:[≥65岁,n=137])按照治疗计划接受ESK(DB1/DB2/DB3:56/84mg;DB4:28/56/84mg)或PBO+新开始的口服抗抑郁药(OAD)。在DB1/DB2/DB4的基线、第28天/戒断早期和随访以及DB3维持阶段的12周间隔期内,进行认知评估--Cogstate电池和霍普金斯言语学习测试-修订版。描述性统计用于分析 ESK 对认知能力的影响,效应大小和 95% 置信区间 (CI) 用于表示相对于活性对比剂+PBO 治疗效果的性质/程度。评估了基线和终点时抑郁严重程度(MADRS评分)与认知能力之间的相关性:基线时,精神运动功能、注意力和记忆力(工作/表象)明显受到轻度至中度损害。在DB1/DB2/DB4中,ESK+OAD组和OAD+PBO组在所有认知测试中的z-分数平均成绩在终点(第28天)和随访评估中与基线相比保持相似/略有改善。同样,在 DB3(仅限于年龄≥65 岁的参与者)中,两组在终点时的认知表现都普遍有所改善。在基线和终点,MADRS评分与认知测试成绩之间的相关性较小:本分析未发现TRD患者接受ESK+OAD短期或长期维持治疗后对认知能力产生负面影响的证据。

Background: Dengue fever, caused by the dengue virus and transmitted through Aedes mosquitoes, is a growing public health concern, particularly in tropical and subtropical regions. Traditionally associated with febrile and hemorrhagic symptoms, recent research suggests a potential link between dengue and cognitive impairments. This systematic review assessed existing research to understand the association between dengue virus infection and cognitive impairments, including dementia, Alzheimer's disease, memory loss, and confusion.

Methods: This systematic review followed PRISMA guidelines. A comprehensive literature search was conducted in PubMed, EMBASE, and Web of Science up to January 18, 2024. Studies examining the prevalence and association of cognitive impairments in dengue patients were included. Data extraction and quality assessment were performed using Nested Knowledge software and the Newcastle-Ottawa Scale.

Results: Of the 1,129 articles identified, five were included in the review, covering a total of 200,873 participants from Taiwan, Brazil, and France. Evidence from population-based cohort studies indicated short-term cognitive impairments, including confusion and memory loss, in some dengue patients. Additionally, long-term risks of dementia, including Alzheimer's disease and vascular dementia, were observed, particularly among older adults. Although the findings suggest there might be an association between dengue infection and cognitive decline, the mechanisms underlying this link remain unclear.

Conclusion: This systematic review suggests that dengue virus infection may affect cognitive function in both acute and long-term contexts. However, the current evidence is not strong enough to establish a conclusive link. Further research with larger sample sizes and longitudinal studies is essential to confirm the impact of dengue virus on cognitive health.

背景:登革热由登革病毒引起,通过伊蚊传播,是一个日益严重的公共卫生问题,尤其是在热带和亚热带地区。登革热传统上与发热和出血性症状有关,最近的研究表明登革热与认知障碍之间存在潜在联系。本系统综述对现有研究进行了评估,以了解登革热病毒感染与认知障碍(包括痴呆症、阿尔茨海默病、记忆力减退和意识模糊)之间的关系:本系统性综述遵循 PRISMA 指南。截至 2024 年 1 月 18 日,在 PubMed、EMBASE 和 Web of Science 上进行了全面的文献检索。纳入了研究登革热患者认知障碍发生率和相关性的研究。采用 Nested Knowledge 软件和纽卡斯尔-渥太华量表进行数据提取和质量评估:在确定的 1,129 篇文章中,有 5 篇被纳入综述,涉及来自台湾、巴西和法国的 200,873 名参与者。来自人群队列研究的证据表明,一些登革热患者会出现短期认知障碍,包括意识模糊和记忆力减退。此外,还观察到痴呆症(包括阿尔茨海默病和血管性痴呆症)的长期风险,尤其是在老年人中。尽管研究结果表明,登革热感染与认知能力下降之间可能存在关联,但这种关联的机制仍不清楚:本系统综述表明,登革热病毒感染可能会在急性和长期情况下影响认知功能。然而,目前的证据还不足以确定两者之间的联系。要确认登革热病毒对认知健康的影响,必须开展样本量更大的进一步研究和纵向研究。

Objective: This study aimed to evaluate the efficacy and safety of lumateperone in treating bipolar disorder and schizophrenia.

Methods: A comprehensive literature search was conducted across multiple databases and websites from inception to July 16, 2024, to identify both published and unpublished randomized controlled trials (RCTs). Meta-analyses were performed using random-effects or fixed-effects models depending on statistical heterogeneity. Relative risks (RRs) or standardized mean differences (SMDs) with 95% confidence intervals (CIs) were used to summarize the effects.

Results: Out of 931 records screened, seven RCTs (four focusing on bipolar depression and three on schizophrenia) were eligible for inclusion. Lumateperone was efficacious in reducing depressive symptoms in bipolar depression (SMDs = -0.36, 95% CI: -0.59 to -0.13). In treating schizophrenia, lumateperone exhibited a lower combined SMD of -0.14 (95% CI: -0.27 to 0, P = 0.051, I² = 49.6%), showing no significant difference from the placebo group, although the p-value approached significance. The lumateperone group showed significantly higher response rates compared to placebo in both bipolar depression (RRs = 1.27, 95% CI: 1.07 to 1.51) and schizophrenia (RRs = 1.44, 95% CI: 1.12 to 1.86). Common treatment-emergent adverse events included somnolence, dry mouth, dizziness, nausea, and headache (RRs = 1.30 to 3.29). Importantly, lumateperone did not significantly increase extrapyramidal symptoms (EPS, RRs = 1.46, 95% CI: 0.84 to 2.53).

Conclusions: Lumateperone is effective in treating bipolar depression but does not significantly reduce symptom severity in schizophrenia. It has a favorable safety and tolerability profile. However, caution is warranted in interpreting these findings due to the limited number of studies included.

研究目的本研究旨在评估鲁米培酮治疗双相情感障碍和精神分裂症的疗效和安全性:方法:我们在多个数据库和网站上进行了全面的文献检索,检索时间从开始到2024年7月16日,以确定已发表和未发表的随机对照试验(RCT)。根据统计异质性,采用随机效应或固定效应模型进行元分析。采用相对风险(RRs)或标准化平均差(SMDs)及 95% 置信区间(CIs)来总结疗效:在筛选出的 931 条记录中,有 7 项研究符合纳入条件(其中 4 项针对双相抑郁症,3 项针对精神分裂症)。鲁马培龙对减少双相抑郁症患者的抑郁症状有疗效(SMD = -0.36,95% CI:-0.59 至 -0.13)。在治疗精神分裂症方面,鲁马培龙的综合SMD较低,为-0.14(95% CI:-0.27至0,P = 0.051,I² = 49.6%),与安慰剂组无显著差异,但P值接近显著。在双相抑郁症(RRs = 1.27,95% CI:1.07 至 1.51)和精神分裂症(RRs = 1.44,95% CI:1.12 至 1.86)方面,鲁马培龙组的应答率明显高于安慰剂组。常见的治疗突发不良事件包括嗜睡、口干、头晕、恶心和头痛(RRs = 1.30 至 3.29)。重要的是,鲁马培龙不会明显增加锥体外系症状(EPS,RRs = 1.46,95% CI:0.84 至 2.53):结论:鲁马培龙能有效治疗双相抑郁症,但不能明显减轻精神分裂症的症状严重程度。它具有良好的安全性和耐受性。然而,由于纳入的研究数量有限,在解释这些研究结果时需要谨慎。

Background: Despite the well-documented efficacy of antidepressant agents for the treatment of major depressive disorder (MDD), initial treatment nonresponse rates are high. Recent years have seen an increase in research into predictive biomarkers toward improving diagnosis and individualized treatment. Among those, epigenetic mechanisms such as DNA methylation constitute promising candidate markers in predicting antidepressant treatment response in MDD. The present study sought to address epigenome-wide DNA methylation as a predictor of antidepressant treatment response in the largest sample to date of patients with MDD.

Methods: Epigenome-wide DNA methylation was analyzed using the Infinium MethylationEPIC BeadChip in peripheral blood of n = 230 Caucasian patients with MDD receiving 6-week antidepressant treatment in a naturalistic in-patient setting as well as in a subsample of n = 107 patients primarily receiving continuous treatment with serotonin reuptake inhibitors or serotonin and norepinephrine reuptake inhibitors. Treatment response was assessed by means of the Hamilton Depression Scale.

Results: No genome-wide significant hits were observed. Suggestive (P < 1E-5) epigenome-wide evidence was discerned for altered DNA methylation at 6 CpG sites (LOC102724467, LOC100506023, RSPO2, SAG, IL16, PRKCI) to predict response to naturalistic antidepressant treatment. In patients treated with serotonin reuptake inhibitors or serotonin and norepinephrine reuptake inhibitors, differential DNA methylation at 11 CpGs, for example, mapping to the TIMP2, VDAC1, or SORL1 genes, was suggestively associated with treatment response.

Conclusions: The present results provide preliminary evidence for altered DNA methylation patterns to be associated with antidepressant treatment response in MDD. Provided significant replication in independent and larger samples, the present findings might in the future aid in clinical decision-making toward more individualized and thus more efficacious treatments of MDD.

背景:尽管抗抑郁药物治疗重度抑郁障碍(MDD)的疗效已得到充分证实,但初始治疗的无应答率却很高。近年来,为改进诊断和个体化治疗,对预测性生物标志物的研究不断增加。其中,DNA 甲基化等表观遗传机制是预测 MDD 抗抑郁治疗反应的有希望的候选标志物。本研究试图将整个表观基因组的DNA甲基化作为迄今为止最大样本的MDD患者抗抑郁治疗反应的预测指标:采用Infinium MethylationEPIC BeadChip分析了在自然住院环境中接受六周抗抑郁治疗的230名白种MDD患者外周血中的表观基因组DNA甲基化,以及主要接受SSRIs或SNRIs持续治疗的107名患者的子样本。治疗反应通过汉密尔顿抑郁量表(HAM-D)进行评估:结果:未观察到全基因组范围内的重大突变。提示性(pConclusions:本研究结果提供了 DNA 甲基化模式改变与 MDD 抗抑郁治疗反应相关的初步证据。如果能在独立的、更大的样本中进行重要的复制,本研究结果将来可能有助于临床决策,从而对 MDD 进行更个体化、更有效的治疗。

Background: Deficits in cognitive control are implicated in numerous neuropsychiatric disorders. However, relevant pharmacological treatments are limited, likely due to weak translational validity of applicable preclinical models used. Neural indices derived from electroencephalography may prove useful in comparing and translating the effects of cognition-enhancing drugs between species. In the current study, we aimed to extend our previous cross-species results by examining if methylphenidate (MPH) modulates behavioral and neural indices of cognitive control in independent cohorts of humans and rats.

Methods: We measured continuous electroencephalography data from healthy adults (n = 25; 14 female) and Long Evans rats (n = 22; 8 female) and compared both stimulus- and response-locked event-related potentials and spectral power measures across species, and their MPH-related moderation following treatment with vehicle (placebo) or 1 of 2 doses of MPH.

Results: Across both species, linear mixed effects modeling confirmed the expected Flanker interference effect on behavior (eg, accuracy) and response-related event-related potentials. Unexpectedly, in contrast to past work, we did not observe any task-related effects on the spectral power of rodents. Moreover, MPH generally did not modulate cognitive control of either species, although some species-specific patterns offer insight for future research.

Conclusions: Collectively, these findings in independent human and rodent subjects replicate some of our previously reported behavioral and neurophysiological patterns partly consistent with the notion that similar neural mechanisms may regulate cognitive control in both species. Nonetheless, these results showcase an approach to accelerate translation using a coordinated between-species platform to evaluate pro-cognitive treatments.

背景:许多神经精神疾病都与认知控制缺陷有关。然而,相关的药物治疗却很有限,这可能是由于适用的临床前模型的转化有效性较弱。脑电图(EEG)得出的神经指数可能有助于比较和转化不同物种间认知增强药物的效果。在目前的研究中,我们旨在通过研究哌醋甲酯(MPH)是否会调节人类和大鼠独立群体的认知控制行为和神经指数,从而扩展我们之前的跨物种研究结果:我们测量了健康成年人(n=25;14只雌性)和Long Evans大鼠(n=22;8只雌性)的连续脑电图数据,并比较了不同物种的刺激和反应锁定事件相关电位(ERPs)和频谱功率测量,以及它们在接受药物(安慰剂)或两种剂量之一的MPH治疗后与MPH相关的调节作用:在两个物种中,线性混合效应模型证实了预期的Flanker干扰对行为(如准确性)和反应相关ERPs的影响。出乎意料的是,与过去的研究不同,我们没有观察到啮齿动物的频谱功率受到任何任务相关的影响。此外,虽然某些物种的特定模式为未来研究提供了启示,但 MPH 一般不会调节这两种动物的认知控制:总之,这些在独立的人类和啮齿动物受试者身上得到的研究结果复制了我们之前报道的一些行为和神经生理学模式,部分符合两种动物中类似的神经机制可能调节认知控制的观点。尽管如此,这些结果展示了一种利用物种间协调平台加速转化的方法,以评估有利于认知的治疗方法。

Background: Phosphodiesterases (PDEs) are enzymes that catalyze the hydrolysis of cyclic adenosine monophosphate AMP (cAMP) and/or cyclic guanosine monophosphate (cGMP). PDE inhibitors can mitigate chronic pain and depression when these disorders occur individually; however, there is limited understanding of their role in concurrent chronic pain and depression. We aimed to evaluate the mechanisms of action of PDE using 2 mouse models of concurrent chronic pain and depression.

Methods: C57BL/6J mice were subjected to partial sciatic nerve ligation (PSNL) to induce chronic neuropathic pain or injected with complete Freund's adjuvant (CFA) to induce inflammatory pain, and both animals showed depression-like behavior. First, we determined the change in PDE expression in both animal models. Next, we determined the effect of PDE7 inhibitor BRL50481 or hippocampal PDE7A knockdown on PSNL- or CFA-induced chronic pain and depression-like behavior. We also investigated the role of cAMP-protein kinase A (PKA)-cAMP response element binding protein (CREB)-brain-derived neurotrophic factor (BDNF) signaling and neuroinflammation in the effect of PDE7A inhibition on PSNL- or CFA-induced chronic pain and depression-like behavior.

Results: This induction of chronic pain and depression in the 2 animal models upregulated hippocampal PDE7A. Oral administration of PDE7 inhibitor, BRL50481, or hippocampal PDE7A knockdown significantly reduced mechanical hypersensitivity and depression-like behavior. Hippocampal PDE7 inhibition reversed PSNL- or CFA-induced downregulation of cAMP and BDNF and the phosphorylation of PKA, CREB, and p65. cAMP agonist forskolin reversed these changes and caused milder behavioral symptoms of pain and depression. BRL50481 reversed neuroinflammation in the hippocampus in PSNL mice.

Conclusions: Hippocampal PDE7A mediated concurrent chronic pain and depression in both mouse models by inhibiting cAMP-PKA-CREB-BDNF signaling. Inhibiting PDE7A or activating cAMP-PKA-CREB-BDNF signaling are potential strategies to treat concurrent chronic pain and depression.

背景:磷酸二酯酶(PDE)是催化环磷酸腺苷 AMP(cAMP)和/或环磷酸鸟苷(cGMP)水解的酶。当慢性疼痛和抑郁症单独发生时,PDE 抑制剂可减轻这两种疾病;然而,人们对其在同时发生的慢性疼痛和抑郁症中的作用了解有限。我们的目的是利用两种并发慢性疼痛和抑郁的小鼠模型来评估 PDE 的作用机制:方法:对 C57BL/6J 小鼠进行坐骨神经部分结扎(PSNL)以诱导慢性神经病理性疼痛,或注射完全弗氏佐剂(CFA)以诱导炎症性疼痛,两种动物均表现出抑郁样行为。首先,我们测定了两种动物模型中 PDE 表达的变化。接着,我们测定了 PDE7 抑制剂 BRL50481 或海马 PDE7A 敲除对 PSNL 或 CFA 诱导的慢性疼痛和抑郁样行为的影响。我们还研究了cAMP-蛋白激酶A(PKA)-cAMP反应元件结合蛋白(CREB)-脑源性神经营养因子(BDNF)信号传导和神经炎症在PDE7A抑制对PSNL或CFA诱导的慢性疼痛和抑郁样行为的影响中的作用:结果:在两种动物模型中诱导慢性疼痛和抑郁会上调海马 PDE7A。口服 PDE7 抑制剂 BRL50481 或敲除海马 PDE7A 能显著降低机械过敏性和抑郁样行为。抑制海马 PDE7 可逆转 PSNL 或 CFA 诱导的 cAMP 和 BDNF 下调以及 PKA、CREB 和 p65 的磷酸化。BRL50481 逆转了 PSNL 小鼠海马的神经炎症:抑制 PDE7A 或激活 cAMP-PKA-CREB-BDNF 信号是治疗并发慢性疼痛和抑郁症的潜在策略。

Background: Cognitive deficits reflecting impaired executive function are commonly associated with psychiatric disorders, including substance use. Cognitive training is proposed to improve treatment outcomes for these disorders by promoting neuroplasticity within the prefrontal cortex, enhancing executive control, and mitigating cognitive decline due to drug use. Additionally, brain derived neurotrophic factor (BDNF) can facilitate plasticity in the prefrontal cortex and reduce drug-seeking behaviors. We investigated whether working memory training could elevate BDNF levels in the prefrontal cortex and if this training would predict or protect against cocaine or cannabinoid seeking.

Methods: Adult male rats were trained to perform a "simple" or "complex" version of a delayed-match-to-sample working memory task. Rats then self-administered cocaine or the synthetic cannabinoid WIN55,212-2 and were tested for cued drug seeking during abstinence. Tissue from the prefrontal cortex and dorsal hippocampus was analyzed for BDNF protein expression.

Results: Training on the working memory task enhanced endogenous BDNF protein levels in the prelimbic prefrontal cortex but not the dorsal hippocampus. Working memory training did not impact self-administration of either drug but predicted the extent of WIN self-administration and cocaine seeking during abstinence.

Conclusions: These results suggest that working memory training promotes endogenous BDNF but does not alter drug-seeking or drug-taking behavior. However, individual differences in cognitive performance before drug exposure may predict vulnerability to future drug use.

背景:认知缺陷反映出执行功能受损,通常与精神疾病(包括药物使用)有关。认知训练可促进前额叶皮层的神经可塑性,增强执行控制能力,缓解吸毒导致的认知能力下降,从而改善这些疾病的治疗效果。此外,脑源性神经营养因子(BDNF)可以促进前额叶皮层的可塑性,减少寻求毒品的行为。我们研究了工作记忆训练是否能提高前额叶皮层的BDNF水平,以及这种训练是否能预测或防止可卡因或大麻素寻求行为:方法:训练成年雄性大鼠完成 "简单 "或 "复杂 "版本的延迟匹配到样本工作记忆任务。然后,大鼠自行服用可卡因或合成大麻素 WIN55,212-2,并在戒断期间接受诱导药物寻求测试。对前额叶皮层和海马背侧的组织进行了 BDNF 蛋白表达分析:结果:工作记忆任务训练提高了边缘前额叶皮层的内源性 BDNF 蛋白水平,但没有提高海马背侧的内源性 BDNF 蛋白水平。工作记忆训练对两种药物的自我给药均无影响,但可预测戒断期间WIN自我给药和可卡因寻求的程度:这些结果表明,工作记忆训练能促进内源性BDNF,但不会改变寻求毒品或服用毒品的行为。然而,药物暴露前认知表现的个体差异可能预示着未来药物使用的脆弱性。
