Previous research examining hypothalamic-pituitary-adrenal (HPA) axis activity in generalised anxiety disorder (GAD) has suggested a general hypercortisolism. These studies have mostly relied on salivary, plasma or urinary assessments, reflecting cortisol secretion over short time periods. The current study utilised the novel method of cortisol assessment in hair to obtain a retrospective index of cortisol secretion over a prolonged period of time. Hair cortisol levels were determined in 15 GAD patients and in 15 age- and gender-matched controls. In addition, participants collected six saliva samples (on awakening, +30 min, 12:00, 16:00, 20:00 h and at bedtime) on two consecutive weekdays for the assessment of the diurnal cortisol profile. Results revealed significantly lower (50-60%) cortisol levels in the first and second 3-cm hair segments of GAD patients compared to those of controls. No significant between-group differences were seen in diurnal cortisol profiles. The hair cortisol findings tentatively suggest that under naturalistic conditions GAD is associated with hypocortisolism. If corroborated by future research, this demonstrates the important qualities of cortisol measurement in hair as an ecologically valid, retrospective index of long-term cortisol secretion and as a marker for psychiatric disorders associated with hypo- or hypercortisolism.

The present review was conducted in order to evaluate the current diagnostic criteria for specific phobia (SP) in light of the empirical evidence gathered since DSM‐IV and to propose changes to DSM‐V where change is clearly and reliably indicated by the evidence. In response to questions put forth by the DSM‐V Anxiety, OC Spectrum, Posttraumatic, and Dissociative Disorder Work Group, four primary areas were determined for this review: the accuracy and utility of the current SP type classification system, the validity of test anxiety as a type of SP, the boundary between agoraphobia and SP, and the reliability and utility of the diagnostic criteria for SP. Developmental issues are addressed within each area. Literature reviews examining academic findings published between 1994 and 2009 were carried out and the results are included herein. The review presents a number of options and preliminary recommendations to be considered for DSM‐V. All of these recommendations should be considered tentative as they await the field trials and expert consensus necessary prior to their inclusion in the DSM‐V. The present review also reveals a great need for future research in the area of SP and directions for such research is provided. Depression and Anxiety, 2010.

BACKGROUND Maternal perinatal mental health has been shown to be associated with adverse consequences for the mother and the child. However, studies considering the effect of DSM-IV anxiety disorders beyond maternal self-perceived distress during pregnancy and its timing are lacking. AIMS To examine the role of maternal anxiety disorders with an onset before birth and self-perceived distress during pregnancy for unfavourable maternal, obstetric, neonatal and childhood outcomes. STUDY DESIGN DSM-IV mental disorders and self-perceived distress of 992 mothers as well as obstetric, neonatal and childhood outcomes of their offspring were assessed in a cohort sampled from the community using the Munich-Composite International Diagnostic Interview. Logistic regression analyses revealed associations (odds ratios) between maternal anxiety disorders and self-perceived distress during pregnancy with maternal depression after birth and a range of obstetric, neonatal and childhood psychopathological outcomes. RESULTS Lifetime maternal anxiety disorders were related to offspring anxiety disorders, but not to offspring externalizing disorders. Analyses focussing on maternal DSM-IV anxiety disorders before birth yielded associations with incident depression after birth. In addition, self-perceived distress during pregnancy was associated with maternal depression after birth, preterm delivery, caesarean section, separation anxiety disorder, ADHD, and conduct disorder in offspring. CONCLUSION Findings confirm the transmission of anxiety disorders from mother to offspring. Apart from maternal anxiety, self-perceived distress during pregnancy also emerged as a putative risk factor for adverse outcomes. The finding that maternal anxiety disorders before birth yielded less consistent associations, suggests that self-perceived distress during pregnancy might be seen as a putative moderator/mediator in the familial transmission of anxiety.

Developmental Epidemiology of Anxiety Disorders

Katja Beesdo-Baum; Susanne Knappe

This review focuses on developmental aspects in the epidemiology of anxiety disorders including prevalence, onset, natural course, longitudinal outcome, and correlates and risk factors, with focus on childhood through young adulthood. Anxiety disorders are frequent and early-emerging conditions. They may remit spontaneously; however, the same or other mental disorders often recur. Although risk factors have been identified, more work is needed to identify the most powerful predictors for onset and the progression to more complex forms of psychopathology and to understand the underlying mechanisms and interactions. This identification is crucial to facilitate research prevention, early interventions, and treatment programs.

Agoraphobia: a review of the diagnostic classificatory position and criteria

Hans-Ulrich Wittchen; Andrew T. Gloster; Katja Beesdo-Baum; Giovanni A. Fava; Michelle G. Craske

The status of agoraphobia (AG) as an independent diagnostic category is reviewed and preliminary options and recommendations for the fifth edition of The Diagnostic and Statistical Manual (DSM‐V) are presented. The review concentrates on epidemiology, psychopathology, neurobiology, vulnerability and risk factors, clinical course and outcome, and correlates and consequences of AG since 1990. Differences and similarities across conventions and criteria of DSM and ICD‐10 are considered. Three core questions are addressed. First, what is the evidence for AG as a diagnosis independent of panic disorder? Second, should AG be conceptualized as a subordinate form of panic disorder (PD) as currently stipulated in DSM‐IV‐TR? Third, is there evidence for modifying or changing the current diagnostic criteria? We come to the conclusion that AG should be conceptualized as an independent disorder with more specific criteria rather than a subordinate, residual form of PD as currently stipulated in DSM‐IV‐TR. Among other issues, this conclusion was based on psychometric evaluations of the construct, epidemiological investigations which show that AG can exist independently of panic disorder, and the impact of agoraphobic avoidance upon clinical course and outcome. However, evidence from basic and clinic validation studies remains incomplete and partly contradictory. The apparent advantages of a more straightforward, simpler classification without implicit hierarchies and insufficiently supported differential diagnostic considerations, plus the option for improved further research, led to favoring the separate diagnostic criteria for AG as a diagnosis independent of panic disorder.

BACKGROUND Peripartum anxiety and depressive disorders are associated with adverse consequences for mother and child. Thus, it is important to examine risk factors, correlates and course patterns of anxiety and depressive disorders during pregnancy and after delivery. METHODS In the prospective-longitudinal Maternal Anxiety in Relation to Infant Development (MARI) Study, n=306 expectant mothers were recruited from gynaecological outpatient settings in Germany and completed up to seven waves of assessment from early pregnancy until 16 months postpartum. Anxiety and depressive disorders and potential risk factors/correlates were assessed with the Composite International Diagnostic Interview for Women (CIDI-V), medical records and additional questionnaires. RESULTS Although peripartum anxiety and depressive disorders appeared to be persistent in some women, others reported major changes with heterogeneous courses and shifts between diagnoses and contents. There was a considerable amount of incident disorders. Strongest predictors for peripartum anxiety and depressive disorders were anxiety and depressive disorders prior to pregnancy, but psychosocial (e.g. maternal education), individual (e.g. low self-esteem), and interpersonal (e.g. partnership satisfaction, social support) factors were also related. LIMITATION Knowing the aims of the study, some participants may have been more encouraged to report particular symptoms, but if so, this points to the importance of a comprehensive assessment in perinatal care. CONCLUSION Peripartum time is a sensitive period for a considerable incidence or persistence/recurrence of anxiety and depressive disorders albeit the course may be rather heterogeneous. Interventional studies are needed to examine whether an alteration of associated factors could help to prevent peripartum anxiety and depressive disorders.

The structure of common mental disorders: A replication study in a community sample of adolescents and young adults

Katja Beesdo-Baum; Michael Höfler; Andrew T. Gloster; Jens Klotsche; Roselind Lieb; André Beauducel; Markus Bühner; Ronald C. Kessler; Hans-Ulrich Wittchen

Previous research suggests that patterns of comorbidity of common mental disorders among adults are best reflected by a hierarchical three‐factor structure with two correlated factors (‘anxious‐misery’ and ‘fear’) summarized in a second‐order ‘internalizing’ factor and one ‘externalizing’ factor. This three‐factor structure has not been examined yet in a sample of adolescents and young adults.

Assessment and treatment of anxiety disorders in children and adolescents.

Anna M. Wehry; Katja Beesdo-Baum; Meghann M. Hennelly; Sucheta Connolly; Jeffrey R. Strawn

Recent advances in the developmental epidemiology, neurobiology, and treatment of pediatric anxiety disorders have increased our understanding of these conditions and herald improved outcomes for affected children and adolescents. This article reviews the current epidemiology, longitudinal trajectory, and neurobiology of anxiety disorders in youth. Additionally, we summarize the current evidence for both psychotherapeutic and psychopharmacologic treatments of fear-based anxiety disorders (e.g., generalized, social, and separation anxiety disorders) in children and adolescents. Current data suggest that these disorders begin in childhood and adolescence, exhibit homotypic continuity, and increase the risk of secondary anxiety and mood disorders. Psychopharmacologic trials involving selective serotonin reuptake inhibitors (SSRIs) and selective serotonin norepinephrine reuptake inhibitors (SSNRIs) are effective in pediatric patients with anxiety disorders and have generally demonstrated moderate effect sizes. Additionally, current data support cognitive behavioral therapy (CBT) for the treatment of these conditions in youth and suggest that the combination of psychotherapy + an SSRI may be associated with greater improvement than would be expected with either treatment as monotherapy.

Neural structures, functioning and connectivity in Generalized Anxiety Disorder and interaction with neuroendocrine systems: A systematic review

Kevin Hilbert; Ulrike Lueken; Katja Beesdo-Baum

BACKGROUND Research on the neurobiological basis of Generalized Anxiety Disorder (GAD) has considerably expanded in recent years. However, many studies investigated different domains and used different methods and paradigms. Therefore, this review aims to integrate the findings to date and to identify the core correlates of neurobiological underpinnings of GAD discovered so far. METHODS We conducted a systematic review of original papers investigating neural correlates, connectivity, or structural changes as well as reporting changes in the serotonergic system, noradrenergic system and cortisol levels in DSM-IV-defined GAD samples until December 2013. RESULTS Studies have identified abnormal amygdala and prefrontal cortex activation in patients and decreased functional connectivity between these areas. Furthermore, studies showed increased gray matter volume and decreased structural connectivity between these structures. Neuroendocrine findings are less consistent, but increased reactivity of the noradrenergic system and perpetuations in the cortisol secretion have been reported. LIMITATIONS Only studies on DSM-IV defined Generalized Anxiety Disorder which employed a group comparison were included. CONCLUSIONS Current research suggests a distinct set of neurobiological alterations in Generalized Anxiety Disorder. However, future research on the interaction between these structures and systems and on the specificity of these findings in relation to other mental disorders is urgently needed.
