Major depression is a complex disorder with no single, direct causal mechanism. Morbidity has been linked to genetic processes, developmental history, and unique environmental exposures. Epigenetic mechanisms, especially DNA methylation, are also likely important factors in the pathogenesis of major depressive disorder (MDD). A community-based twin sample has many advantages for epigenetic studies, given the shared genetic and developmental histories of same-sex twin pairs. This article describes the rationale and study design for the Mood and Methylation Study in which 133 twin pairs (101 monozygotic and 32 dizygotic), both discordant and concordant for lifetime history of MDD, were evaluated on a large number of variables related to MDD. The twins also provided blood samples for an epigenome-wide association study of differentially methylated regions (DMR) relevant to MDD. Although MDD is typically considered a disorder of the central nervous system, it is unfeasible to obtain a large sample of brain tissues. However, epigenetic variation is not limited to the affected tissue but can also be detected in peripheral blood leukocytes. Thus, this study focused on monocytes for the major analyses. Additional plans for the study include gene expression analysis from the same set of twins using RNA-seq and validation of significant DMRs in postmortem brain tissues from a separate sample. Moreover, sufficient samples have been collected to perform future ‘multi-omic’ analyses, including metabolome, microbiome, and transcriptome. Our long-term goal is to understand how epigenomic and other ‘omic’ factors can be manipulated for diagnostic, preventive, and therapeutic purposes for MDD and its related conditions.

Background
Better indicators of prognosis are needed to personalise post-traumatic stress disorder (PTSD) treatments.
AimsWe aimed to evaluate early symptom reduction as a predictor of better outcome and examine predictors of early response.
MethodPatients with PTSD (N = 134) received sertraline or prolonged exposure in a randomised trial. Early response was defined as 20% PTSD symptom reduction by session two and good end-state functioning defined as non-clinical levels of PTSD, depression and anxiety.
ResultsEarly response rates were similar in prolonged exposure and sertraline (40 and 42%), but in sertraline only, early responders were four times more likely to achieve good end-state functioning at post-treatment (Number Needed to Treat = 1.8, 95% CI 1.28–3.00) and final follow-up (Number Needed to Treat = 3.1, 95% CI 1.68–16.71). Better outcome expectations of sertraline also predicted higher likelihood of early response.
ConclusionsHigher expectancy of sertraline coupled with early response may produce a cascade-like effect for optimal conditions for long-term symptom reduction. Therefore, assessing expectations and providing clear treatment rationales may optimise sertraline effects.

Collaborative care is a well-studied and effective model of integrating behavioural healthcare into primary care medical settings. Despite evidence of its effectiveness, it has been difficult to implement into the US healthcare system. The upcoming reorganisation of US healthcare will rely heavily on adaptations of this model to improve its uptake and cost-effectiveness.

Background
Some data suggest that older adults with anxiety disorders do not respond as well to treatment as do younger adults.
AimsWe examined age differences in outcomes from the Coordinated Anxiety Learning and Management (CALM) study, an effectiveness trial comparing usual care to a computer-assisted collaborative care intervention for primary care patients with panic disorder, generalised anxiety disorder, post-traumatic stress disorder (PTSD), and/or social anxiety disorder. This is the first study to examine the efficacy of a collaborative care intervention in a sample that included both younger and older adults with anxiety disorders. We hypothesised that older adults would show a poorer response to the intervention than younger adults.
MethodWe examined findings for the overall sample, as well as within each diagnostic category (clinicaltrials.gov identifier: NCT00347269).
ResultsThe CALM intervention was more effective than usual care among younger adults overall and for those with generalised anxiety disorder, panic disorder and social anxiety disorder. Among older adults, the intervention was effective overall and for those with social anxiety disorder and PTSD but not for those with panic disorder or generalised anxiety disorder. The effects of the intervention also appeared to erode by the 18-month follow-up, and there were no significant effects on remission among the older adults.
ConclusionsThese results are consistent with the findings of other investigators suggesting that medications and psychotherapy for anxiety disorders may not be as effective for older individuals as they are for younger people.

Summary
Editor's note
Panic disorder is a relatively new diagnosis that did not exist formally before 1980, when it was first introduced into DSM-III. Its introduction divided the primary anxiety disorders into panic and generalized anxiety disorder. The assets of the diagnosis are also its handicaps. The experience of a panic attack is so profound that it cannot but be remembered starkly and clearly, and so the definition of a panic attack is remarkably easy. However, most psychiatrists never see someone having a severe panic attack, and so the reporting of symptoms is for the most part retrospective and possibly distorted by the experience. This has led to difficulty in defining panic disorder, and the official classifications of DSM and ICD differ to some extent in that ICD-10 maintains that the panic attacks in panic disorder ‘are not consistently associated with a specific symptom or object’ (as when they are symptoms forming part of a phobic disorder), whereas in DSM IV, the exclusion clause that ‘they are not better accounted for by another mental disorder’ is much more open to interpretation. Panic attacks are said to be ‘uncued’ (i.e. they come ‘out of the blue’), but increasingly, as this chapter illustrates, they are often associated with a variety of cues. It is a condition which is not so much treated, but prevented, as the successful treatments prevent the disorder (i.e. stop) the panic attacks rather than treat them.

Background. Panic disorder is a prevalent, often disabling, disorder among primary-care patients, but there are large gaps in quality of treatment in primary care. This study describes the incremental cost-effectiveness of a combined cognitive behavioral therapy (CBT) and pharmacotherapy intervention for patients with panic disorder versus usual primary-care treatment.
Method. This randomized control trial recruited 232 primary-care patients meeting DSM-IV criteria for panic disorder from March 2000 to March 2002 from six primary-care clinics from university-affiliated clinics at the University of Washington (Seattle) and University of California (Los Angeles and San Diego). Patients were randomly assigned to receive either treatment as usual or a combined CBT and pharmacotherapy intervention for panic disorder delivered in primary care by a mental health therapist. Intervention patients had up to six sessions of CBT modified for the primary-care setting in the first 12 weeks, and up to six telephone follow-ups over the next 9 months. The primary outcome variables were total out-patient costs, anxiety-free days (AFDs) and quality adjusted life-years (QALYs).
Results. Relative to usual care, intervention patients experienced 60·4 [95% confidence interval (CI) 42·9–77·9] more AFDs over a 12-month period. Total incremental out-patient costs were $492 higher (95% CI $236–747) in intervention versus usual care patients with a cost per additional AFD of $8.40 (95% CI $2.80–14.0) and a cost per QALY ranging from $14158 (95% CI $6791–21496) to $24776 (95% CI $11885–37618). The cost per QALY estimate is well within the range of other commonly accepted medical interventions such as statin use and treatment of hypertension.
Conclusions. The combined CBT and pharmacotherapy intervention was associated with a robust clinical improvement compared to usual care with a moderate increase in ambulatory costs.

Background. Excessive worry is required by DSM-IV, but not ICD-10, for a diagnosis of generalized anxiety disorder (GAD). No large-scale epidemiological study has ever examined the implications of this requirement for estimates of prevalence, severity, or correlates of GAD.
Method. Data were analyzed from the US National Comorbidity Survey Replication, a nationally representative, face-to-face survey of adults in the USA household population that was fielded in 2001–2003. DSM-IV GAD was assessed with Version 3.0 of the WHO Composite International Diagnostic Interview. Non-excessive worriers meeting all other DSM-IV criteria for GAD were compared with respondents who met full GAD criteria as well as with other survey respondents to consider the implications of removing the excessiveness requirement.
Results. The estimated lifetime prevalence of GAD increases by ~40% when the excessiveness requirement is removed. Excessive GAD begins earlier in life, has a more chronic course, and is associated with greater symptom severity and psychiatric co-morbidity than non-excessive GAD. However, non-excessive cases nonetheless evidence substantial persistence and impairment of GAD, high rates of treatment-seeking, and significantly elevated co-morbidity compared with respondents without GAD. Non-excessive cases also have sociodemographic characteristics and familial aggregation of GAD comparable to excessive cases.
Conclusions. Individuals who meet all criteria for GAD other than excessiveness have a somewhat milder presentation than those with excessive worry, yet resemble excessive worriers in a number of important ways. These findings challenge the validity of the excessiveness requirement and highlight the need for further research into the optimal definition of GAD.

Background. Empirical findings suggest that psychiatric illness is associated with cardiovascular disease (CVD). The purpose of this study was to compare the strength of the association of lifetime post-traumatic stress disorder (PTSD) and lifetime major depression on CVD among Northern Plains American Indians.
Method. A total of 1414 participants aged 18–57 years completed a structured interview that assessed psychiatric diagnoses, alcohol abuse/dependence, self-reported CVD, and traditional CVD risk factors including age, sex, education, diabetes, high blood pressure, and smoking. Logistic regression analyses compared the odds ratios of CVD in participants with and without diagnosed PTSD or major depression.
Results. The rates of lifetime PTSD and major depression were 15% and 8% respectively. CVD was more commonly reported by participants with PTSD than by those without PTSD (12% v. 5%, p[les ]0·01). Likewise, more participants with major depression reported CVD than did their non-depressed counterparts (14% v. 6%, p[les ]0·05). PTSD was significantly associated with CVD even after controlling for traditional CVD risk factors and major depression (odds ratio 2·0, confidence interval 1·1–3·8). In contrast, the association of major depression with CVD was not significant after accounting for both traditional risk factors and PTSD.
Conclusions. Rates of PTSD are high in American Indian communities. Rising CVD rates in this population may be better understood if PTSD is considered along with other traditional risk factors. Future research should examine the association and mechanisms of PTSD and CVD prospectively. Such data could lead to more effective CVD prevention efforts for American Indians.

Background.Randomized clinical trials indicate a benefit from combining medications with cognitive behavioral therapy (CBT) relative to medication alone for panic disorder. Using an as-treated analysis, we evaluated whether the addition of CBT enhanced outcomes for panic disorder relative to medications alone in the primary-care setting.
Method.Primary-care patients with panic disorder reported on their receipt of CBT and medications over the 3 months following baseline assessment. The degree to which outcomes for those who used anti-panic medications were enhanced by the receipt of at least one component of CBT was analyzed using a propensity score model that took into account observable baseline patient characteristics influencing both treatment selection and outcomes.
Results.The addition of CBT resulted in statistically and clinically significant improvements at 3 months on anxiety sensitivity, social avoidance, and disability. Also, patients receiving CBT in the first 3 months of the study were more improved at 12 months than patients who took medications only during the first 3 months of the study.
Conclusions.The clinical utility of the findings are discussed in terms of the importance of primary-care physicians encouraging their panic disorder patients to receive CBT as well as medications.

Background. The proposed revisions of the ICD and DSM diagnostic systems have led to increased interest in evaluation of diagnostic criteria. This report focuses on the DSM-IV requirement that episodes of generalized anxiety disorder (GAD) must persist for at least 6 months. Community epidemiological data are used to study the implications of changing this requirement in the range 1–12 months for estimates of prevalence, onset, course, impairment, co-morbidity, associations with parental GAD, and sociodemographic correlates.
Method. Data come from the US National Comorbidity Survey Replication (NCS-R), a US household survey carried out during 2001–2003. Version 3.0 of the WHO Composite International Diagnostic Interview (WMH-CIDI) was used to assess DSM-IV anxiety disorders, mood disorders, substance disorders, and impulse-control disorders.
Results. Lifetime, 12-month, and 30-day prevalence estimates of DSM-IV GAD changed from 6·1%, 2·9%, and 1·8% to 4·2–12·7%, 2·2–5·5%, and 1·6–2·6% when the duration requirement was changed from 6 months to 1–12 months. Cases with episodes of 1–5 months did not differ greatly from those with episodes of [ges ]6 months in onset, persistence, impairment, co-morbidity, parental GAD, or sociodemographic correlates.
Conclusions. A large number of people suffer from a GAD-like syndrome with episodes of <6 months duration. Little basis for excluding these people from a diagnosis is found in the associations examined here.

Background
Up to three-quarters of patients with fatigue syndromes have comorbid mood or anxiety disorders, suggesting that chronic fatigue is a forme fruste of anxiety or depressive states.
AimsTo establish whether the association of chronic fatigue with psychological distress is causal or due to a common genetic or environmental factor.
Method69 monozygotic (MZ) and 31 dizygotic (DZ) female twin pairs, with only one co-twin reporting at least 6 months of fatigue, completed questions on fatigue, the General Health Questionnaire (GHQ) and a structured psychiatric interview. We examined the effects of three progressively more stringent definitions of chronic fatigue on four GHQ sub-scales.
ResultsFatigued MZ and DZ twins by all definitions were significantly more depressed, anxious, somatically preoccupied and socially dysfunctional than their non-fatigued co-twins. Intrapair differences were similar in DZ and MZ twins, but non-significant differences were observed for the somatic symptoms and anxiety/insomnia sub-scales.
ConclusionsIn this sample, chronic fatigue and psychological distress are strongly associated without evidence for genetic covariation, implying that the association is environmental, or due to overlapping definitions. Any genetic covariation missed is likely to involve anxiety rather than depression.

Background
Most prior studies of panic-depression comorbidity have been limited methodologically by use of small clinical samples and incomplete analyses.
AimsGeneral population data were used to study the association of lifetime and recent (12 months) panic–depression comorbidity with symptom severity, impairment, course and help-seeking in the National Comorbidity Survey (NCS).
MethodThe NCS is a nationally representative survey of the prevalences and correlates of major DSM–III–R disorders in the US household population.
ResultsStrong lifetime and current comorbidity were found between panic and depression. Comorbidity was associated with greater symptom severity, persistence, role impairment, suicidality and help-seeking, with many findings persisting after controlling for additional comorbid diagnoses. Findings did not differ according to which disorder was chronologically primary.
ConclusionsBoth lifetime and current panic–depression comorbidity are markers for more severe, persistent and disabling illness. Neither additional comorbid diagnoses nor the primary–secondary distinction were important moderators of these associations.

The definition and clinical aspects of rapid cycling affective illness are reviewed and various factors associated with the onset and maintenance of rapid cycling enumerated. On the basis of this information and of reports of the response of rapid cycling patients to various treatment interventions, an approach is suggested to the evaluation and treatment of rapid cycling affective illness.
