    BACKGROUND & AIMS: :The current trial examined the value of modifying empirically validated treatment for childhood anxiety for application via written materials for parents of anxious children. Two hundred sixty-seven clinically anxious children ages 6-12 years and their parents were randomly allocated to standard group treatment, waitlist, or a bibliotherapy version of treatment for childhood anxiety. In general, parent bibliotherapy demonstrated benefit for children relative to waitlist but was not as efficacious as standard group treatment. Relative to waitlist, use of written materials for parents with no therapist contact resulted in around 15% more children being free of an anxiety disorder diagnosis after 12 and 24 weeks. These results have implications for the dissemination and efficient delivery of empirically validated treatment for childhood anxiety.
    背景与目标: : 当前的试验研究了修改经经验验证的儿童焦虑症治疗的价值,以通过书面材料为焦虑儿童的父母应用。将67名6-12岁的临床焦虑儿童及其父母随机分配到标准组治疗,候补名单或针对儿童焦虑症的书目疗法版本。通常,相对于候补名单,父母书目疗法对儿童具有益处,但效果不如标准组治疗。相对于候补名单,没有治疗师联系的父母使用书面材料导致大约15% 多的孩子在12周和24周后没有焦虑症诊断。这些结果对传播和有效实施经经验验证的儿童焦虑症治疗有影响。

    BACKGROUND & AIMS: :Neuroimaging comprises a set of tools, which include different types of magnetic resonance imaging such as functional magnetic resonance imaging (fMRI), Magnetic Resonance Spectroscopy (MRS), Arterial Spin Labeling (ASL), and radiotracer imaging such as positron emission tomography and single photon emission computed tomography. The focus of this review is to address the question whether fMRI can contribute to the diagnosis and treatment of anxiety disorders. Key anxiety processes and neural substrates are reviewed. The main findings and shortcomings of fMRI in the context of anxiety are briefly summarized. Finally, the next stages of developing fMRI for diagnosis and treatment are highlighted. The main conclusion of this review is that fMRI could become a clinical tool for the diagnosis and treatment of anxiety disorders, but neuroimaging groups will need to better develop its specificity and sensitivity so that fMRI results can be meaningful for an individual patient not just for groups of individuals.
    背景与目标: : 神经成像包括一组工具,其中包括不同类型的磁共振成像,例如功能磁共振成像 (fMRI),磁共振波谱 (MRS),动脉自旋标记 (ASL) 和放射性示踪剂成像,例如正电子发射断层扫描和单光子发射计算机断层扫描。这篇综述的重点是解决功能磁共振成像是否有助于焦虑症的诊断和治疗的问题。回顾了关键的焦虑过程和神经底物。简要总结了焦虑背景下功能磁共振成像的主要发现和缺点。最后,重点介绍了开发用于诊断和治疗的功能磁共振成像的下一阶段。这篇综述的主要结论是,功能磁共振成像可能成为诊断和治疗焦虑症的临床工具,但神经成像组需要更好地发展其特异性和敏感性,以便功能磁共振成像结果对单个患者有意义,而不仅仅是对个体群体有意义。

    BACKGROUND & AIMS: :During development, when inhibitory and excitatory synapses are formed and refined, homeostatic mechanisms act to adjust inhibitory input in order to maintain neural activity within a normal range. As the brain matures, synaptogenesis slows and a relatively stable level of inhibition is achieved. Deficits in inhibitory neurotransmission are associated with increased anxiety-related behavior and drugs that potentiate GABA function, the major inhibitory neurotransmitter in the brain, are effective anxiolytics. These observations raise the possibility that transient perturbations in the activity of neural circuits during development might induce compensatory changes in inhibition that could persist into adulthood and contribute to changes in anxiety-related behavior. To test this hypothesis, we treated mice continuously during the major period of forebrain synaptogenesis (P14-28) with the GABA-A receptor positive modulator diazepam and assessed anxiety-related behavior in adulthood. Control experiments confirmed anxiolytic effects of the drug following one day of treatment and the development of tolerance following two weeks of treatment. When tested in adulthood, one month after the end of treatment, diazepam-treated mice exhibited significantly increased behavioral inhibition in the open-field, elevated-plus maze, and novel object behavioral paradigms. Levels of benzodiazepine binding sites in amygdala and frontal cortex were specifically decreased in diazepam-treated mice demonstrating that homeostatic adjustments in GABA function persist into adulthood. Our results show that increased GABAergic activity can affect the developmental programming of anxiety-related behavior.
    背景与目标: : 在发育过程中,当形成和完善抑制性和兴奋性突触时,稳态机制会调节抑制性输入,以将神经活动维持在正常范围内。随着大脑的成熟,突触发生减慢,并达到相对稳定的抑制水平。抑制性神经传递的缺陷与焦虑相关行为的增加有关,增强大脑中主要的抑制性神经递质GABA功能的药物是有效的抗焦虑药。这些观察结果增加了以下可能性: 发育过程中神经回路活动的瞬时扰动可能会引起抑制的补偿性变化,这种变化可能会持续到成年并导致焦虑相关行为的变化。为了验证这一假设,我们在前脑突触发生 (P14-28) 的主要时期连续使用GABA-A受体阳性调节剂地西epa治疗小鼠,并评估成年期的焦虑相关行为。对照实验证实了药物在治疗一天后的抗焦虑作用,并在治疗两周后产生了耐受性。在成年后 (治疗结束后一个月) 进行测试时,用地西epa处理的小鼠在开阔视野,高架迷宫和新颖的对象行为范式中表现出明显增强的行为抑制作用。在地西epa治疗的小鼠中,杏仁核和额叶皮层中苯二氮卓类结合位点的水平特异性降低,表明GABA功能的稳态调节持续到成年。我们的结果表明,gaba能活性的增加会影响焦虑相关行为的发育程序。

    BACKGROUND & AIMS: :The neurokinin Substance P (SP) is widely distributed in the central nervous system and has been extensively studied in various functional aspects. This review focuses on the behavioral relevance of SP. Here we show that SP can have memory-promoting, reinforcing and anxiolytic-like effects when administered systemically or into the nucleus basalis of the ventral pallidum. These effects seem to be mediated via the SP-preferring NK(1)receptor and differentially related to N- versus C-terminal fragments of the undecapeptide. Secondly, SP injection into the ventral pallidum can lead to increases of acetylcholine in frontal cortex and dopamine in nucleus accumbens, suggesting that the hypermnestic, positively reinforcing and anxiolytic effects observed upon basal forebrain injection of SP are mediated by activation of the nucleus accumbens-ventral pallidum circuitry. Furthermore, SP and certain SP-fragments may not only be considered to have beneficial behavioral effects in normal animals, but can also prevent lesion-induced functional deficits and improve the speed of recovery. This indicates that SP agonists might also have a neuroprotective capacity in parallel with recovery-promoting actions.
    背景与目标: : 神经激肽p物质 (SP) 广泛分布在中枢神经系统中,并已在各个功能方面进行了广泛研究。本文的重点是SP的行为相关性。在这里,我们表明,SP在全身或腹侧苍白球的基底核中施用时,可以具有促进记忆,增强和抗焦虑的作用。这些作用似乎是通过SP优先的NK(1) 受体介导的,并且与十一肽的N端与C端片段有差异关系。其次,将SP注射到腹侧苍白球中会导致额叶皮质中的乙酰胆碱和伏隔核中的多巴胺增加,这表明在基底前脑注射SP时观察到的高记忆,积极增强和抗焦虑作用是由伏隔核的激活介导的-腹侧苍白球回路。此外,SP和某些SP片段不仅可以被认为在正常动物中具有有益的行为作用,而且还可以防止病变引起的功能缺陷并提高恢复速度。这表明SP激动剂也可能与促进恢复的作用同时具有神经保护能力。

    BACKGROUND & AIMS: BACKGROUND:A comprehensive meta-analysis to identify the proportions of comorbid personality disorders (PD) across the major subtypes of anxiety disorders (AD) has not previously been published. METHODS:A literature search identified 125 empirical papers from the period 1980-2010 on patients with panic disorders, social phobia, generalised anxiety, obsessive-compulsive (OCD) and post-traumatic stress disorder (PTSD). Several moderators were coded. RESULTS:The rate of any comorbid PD was high across all ADs, ranging from .35 for PTSD to .52 for OCD. Cluster C PDs occurred more than twice as often as cluster A or B PDs. Within cluster C the avoidant PD occurred most frequently, followed by the obsessive-compulsive and the dependent PD. PTSD showed the most heterogeneous clinical picture and social phobia was highly comorbid with avoidant PD. A range of moderators were examined, but most were non-significant or of small effects, except an early age of onset, which in social phobia increased the risk of an avoidant PD considerably. Gender or duration of an AD was not related to variation in PD comorbidity. LIMITATIONS:Blind rating of diagnoses was recorded from the papers as an indication of diagnostic validity. However, as too few studies reported it the validity of the comorbid estimates of PD was less strong. CONCLUSIONS:The findings provided support to several of the proposed changes in the forthcoming DSM-5. Further comorbidity studies are needed in view of the substantial changes in how PDs will be diagnosed in the DSM-5.

    BACKGROUND & AIMS: :This study examined the internal consistency and structural/construct validity of the Liebowitz Social Anxiety Scale (LSAS) for community-dwelling subjects in Japan. A cross-sectional study that included 929 participants was conducted. Structural/construct validity was assessed on confirmatory factor analysis. The internal consistency reliability was good for the overall LSAS scale (α = 0.97) and for its original four factors (α = 0.92-0.89). The original four-factor model fit the observed data relatively better than alternative models. These findings indicate that the LSAS is a valid and reliable measure of anxiety symptoms for this community-dwelling population in Japan.

    BACKGROUND & AIMS: BACKGROUND:The purpose of this study was to explore the association of five factors personality traits, as predictor variables, with the anxiety and depression as joint dependent variables in an Iranian adult population. SUBJECTS AND METHODS:A total of 3175 subjects living in Isfahan participated in this cross-sectional population-based study (SEPAHAN) and completed self-administered questionnaires about demographic, life style, gastrointestinal disorders, personality traits, social support, and psychological problems. Data was analyzed using bivariate multiple binary logistic regression in R Free statistical software. RESULTS:The results indicated high scores of neuroticisms increase the risk of anxiety and depression after adjustment for the potential confounders in total sample (OR (95% CI): 1.22 (1.19-1.24) and 1.19 (1.17-1.21), respectively) as well as in both male and female. In contrast, joint inverse associations were found between anxiety and depression with high extraversion (OR (95% CI): 0.90 (0.88-0.92) and 0.91 (0.89-0.92), respectively), agreeableness (0.93 (0.91-0.96) and 0.94 (0.92-0.96) respectively) and conscientiousness scores (0.95 (0.93-0.97) and 0.95 (0.94-0.97) respectively) as well as in both male and female. Furthermore, higher scores of openness had significant inverse association with depression in male. CONCLUSION:The present study indicated that higher scores of neuroticism, however lower extraversion, conscientiousness and agreeableness scores are risk factors for both anxiety and depression in Iranian adult population. It is suggested to perform family studies or twin and genetic association studies with considering combinations of personality traits (personality styles), and also measuring personality traits at the facet level.

    BACKGROUND & AIMS: :Empirical studies suggest that childhood sexual abuse is associated with sexual revictimization by a male romantic partner in female survivors. Yet, the potential mechanisms underlying this association remain understudied. Past studies indicated that women childhood sexual abuse survivors report more sexual anxiety, which in turn was linked to an increased risk of sustaining sexual coercion. The current study, conducted with a sample of 448 adult women from the community, aimed to examine sexual anxiety as a potential mechanism in the association between childhood sexual abuse and sexual coercion sustained by women in heterosexual romantic relationships. Results from path analyses confirmed the indirect effect of sexual anxiety in the relationship between childhood sexual abuse and sexual coercion victimization. Findings indicated that childhood sexual abuse is associated with higher levels of sexual anxiety, which in turn, was linked to a higher frequency of sexual coercion experiences perpetrated by the romantic partner. This study contributes to a better understanding of the determinants of sexual violence against women and provides an empirical basis to better inform prevention initiatives and guide future interventions.

    BACKGROUND & AIMS: BACKGROUND/OBJECTIVE:Anxiety is common in patients experiencing neurocritical illness and their family caregivers. Resilience factors like mindfulness and coping skills may be protective against symptoms of emotional distress, including anxiety. Less is known about the interplay of anxiety symptoms and resilience factors between patients and caregivers. The purpose of this study is to examine the trajectory of anxiety symptoms among dyads of neurocritical care patients without major cognitive impairment and their family caregivers and to elucidate the relationship between resiliency (e.g., mindfulness and coping) and anxiety in these dyads. METHODS:Prospective, longitudinal study of adults admitted to the neurological intensive care unit (Neuro-ICU) and their caregivers. Dyads of patients (N = 102) and family caregivers (N = 103) completed self-report measures of mindfulness (Cognitive Affective Mindfulness Scale-Revised) and coping (Measure of Current Status-Part A) during Neuro-ICU hospitalization and anxiety symptoms (anxiety subscale of the Hospital Anxiety and Depression Scale) during hospitalization and at 3- and 6-month follow-up. We used actor-partner interdependence modeling to predict the effect of one's own baseline characteristics on one's own and one's partner's future anxiety symptoms. RESULTS:Rates of clinically significant anxiety symptoms were 40% for patients and 42% for caregivers at baseline. Of these, 20% of patients and 23% of caregivers showed moderate and severe symptoms. Approximately, one-third of patients and caregivers reported clinically significant anxiety symptoms at 3- and 6-month follow-ups, with more than 20% endorsing moderate or severe symptoms. Patients' own baseline mindfulness, coping, and anxiety symptoms were associated with lower anxiety symptoms at all time points (ps < 0.001)-this was also true for caregivers. For both patients and caregivers, one's own baseline mindfulness predicted their partner's anxiety symptoms 3 months later (p = 0.008), but not at 6-month follow-up. CONCLUSIONS:Anxiety symptoms in Neuro-ICU patient-caregiver dyads are high through 6 months following admission. Mindfulness is interdependent and protective against anxiety in dyads at 3-month but not 6-month follow-up. Early, dyad-based interventions may prevent the development of chronic anxiety in patients without major cognitive impairment and caregivers.

    BACKGROUND & AIMS: AIM:The First Episode Mood and Anxiety Program (FEMAP) is a community-based early intervention program that has been shown to improve health outcomes for emerging adults (EAs) with mood and anxiety disorders. However, not all EAs who are admitted to the program initiate treatment. Our aim was to identify factors that distinguish those who initiated treatment from those who did not. METHODS:FEMAP administered questionnaires to EAs upon first contact with the program, collecting information on a range of socioeconomic, patient and condition-related factors. We compared EAs who initiated treatment in the program (n = 318, 87.4%) to those who did not (n = 46, 12.6%). To examine factors associated with treatment initiation, we specified a parsimonious logistic regression model, using the method of purposeful selection to choose from a range of candidate variables. RESULTS:Anxiety Sensitivity Index - Revised (ASI-R), binge drinking and cannabis use were included in the final logistic regression model. Each one-point increment in the ASI-R score was associated with a 1% increase in the odds of treatment initiation (OR = 1.014; 95% CI [1.003, 1.026]). No other variable was significantly associated with treatment initiation. CONCLUSIONS:Our study provides insight on the differences between EAs with mood and anxiety disorders who initiated targeted treatment services and those who did not. Anxiety sensitivity was significantly associated with treatment initiation at FEMAP. Our findings suggest that it may be anxiety sensitivity, rather than depression or functional impairment per se that drive treatment initiation among EAs.

    BACKGROUND & AIMS: :Comorbidity between balance and anxiety disorders in adult population is a well-studied clinical entity. Children might be particularly prone to develop balance-anxiety comorbidity, but surprisingly they are practically neglected in this field of research. The consequence is that children are treated for what seems to be the primary disorder without noticing possible effects on the other disorder. In Study 1, children with balance dysfunction were compared to normally balanced controls on anxiety and self-esteem. In study 2, children with balance dysfunction were assigned to either balance training or a waiting-list control. Training consisted of 12 weekly sessions of balance treatment. Anxiety and self-esteem were tested before and after treatment/waiting. Study 1 confirmed significantly higher anxiety and lower self-esteem in the balance dysfunction group compared to the control group. Study 2 showed that treatment improved balance performance, reduced anxiety, and increased self-esteem relative to the control waiting list group. Taken together, the present findings are in accord with the observations of comorbidity between balance and anxiety disorders in adults and confirm their validity in children younger than 7 years of age. This profile of comorbidity between balance dysfunction and anxiety also include lower self-esteem.

    BACKGROUND & AIMS: :Mycosis fungoides (MF) is a chronic disease, causing serious morbidities and mortality. This study was designed to measure depression and anxiety levels in MF patients, and quality of life (QoL) assessments and to compare the results with controls. Fifty-two patients with a diagnosis of MF and 52 age and sex matching healthy controls were enrolled in this study. Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI) and the 36-Item Short Form Health Survey (SF-36) were administered to all patients and controls. Mean BAI and BDI scores of the patients with MF were significantly higher than controls. In case of the SF-36, general health perception, emotional, and social functioning scores were significantly lower in MF patients. Depression scores of the patients' were positively correlated with the age of disease onset and negatively correlated with physical functioning scores. Significant negative correlation was detected between eight subscales of the SF-36 and BDI and BAI scores. This study has demonstrated that there is significant impairment of QoL in MF patients MF, with higher anxiety and depression levels, when compared to control group. As the disease progresses, level of depression increases and patients' general health perception deteriorates.

    BACKGROUND & AIMS: :Environmental endocrine disruptors 4-nonylphenol (NP) and 4-tert-octylphenol (OP) may cast huge harm to human health. We used a rat model to observe the influence of NP or/and OP exposure on anxiety-related behaviors and the underlying mechanisms. Eighty male Sprague-Dawley (SD) rats were randomly divided into 10 groups: control group (corn oil), NP groups [30, 90, 270 mg/kg], OP groups [40, 120, 360 mg/kg] and NO groups [(mixed with the corresponding NP, OP alone exposed low, medium and high dose according to the natural environment exists NP:OP = 4:1]. The rats were orally administered every other day for 30 days. The neurobehaviors of rats were evaluated by open-field test (OFT) and elevated plus-maze test (EPM), and the concentrations of 5-HT, monoamine oxidase (MAOA), serotonin transporter (SERT), vesicular monoamine transporter 2 (VAMT2), 5-hydroxytryptamine 1A (5-HT1A), 5-hydroxytryptamine 2A (5-HT2A),and 5-hydroxytryptamine 2C (5-HT2C) in the rat prefrontal cortex were analyzed by ELISA. OFT and EPM tests showed that NP or/and OP exposure induced anxiety-related behaviors in rats. 5-HT levels were significantly increased compared with the control group. The levels of MAOA, SERT, VAMT2, 5-HT1A, 5-HT2A, and 5-HT2C in the prefrontal cortex reduced in different degrees by high-doses NP or/and OP exposure. In summary, NP or/and OP exposure might cause anxiety-related behaviors in rats through regulating neurotransmitter 5-HT levels by altering the expression of 5-HT decomposition enzyme MAOA, transporters SERT and VMAT2, and 5-HT receptors 5-HT1A, 5-HT2A, and 5-HT2C.

    BACKGROUND & AIMS: OBJECTIVES:This study investigates whether, and if so how, anxiety symptoms are related to cognitive decline in elderly persons and whether anxiety symptoms precede cognitive decline. METHOD:Data were obtained from the Longitudinal Aging Study Amsterdam. Anxiety symptoms were measured with the Hospital Anxiety and Depression Scale. General cognitive functioning was measured with the Mini-Mental State Examination, episodic memory with the Auditory Verbal Learning Test, fluid intelligence with the Raven's Coloured Progressive Matrices and information processing speed with the coding task. Multilevel analyses were performed to investigate the relationship between anxiety symptoms and cognitive decline over 9 years, taking into account confounding variables. RESULTS:Although not consistent across all dimensions of cognitive functioning, a curvilinear effect of anxiety on cognitive performance was found. Furthermore, we found that previous measurement of anxiety symptoms were not predictive of cognitive decline at a later time-point. CONCLUSION:This study suggests that the effect of anxiety on cognition depends on the severity of the present anxiety symptoms with mild anxiety associated with better cognition, whereas more severe anxiety is associated with worse cognition. The effect of anxiety symptoms on cognitive functioning seems to be a temporary effect, anxiety is not predictive of cognitive decline.
