The complex relationships between religiosity, spirituality and the risk of DSM-IV depression are not well understood.

We investigated the independent influence of religious service attendance and two dimensions of spiritual well-being (religious and existential) on the lifetime risk of major depression. Data came from the New England Family Study (NEFS) cohort (n=918, mean age=39 years). Depression according to DSM-IV criteria was ascertained using structured diagnostic interviews. Odds ratios (ORs) for the associations between high, medium and low tertiles of spiritual well-being and for religious service attendance and the lifetime risk of depression were estimated using multiple logistic regression.

Religious service attendance was associated with 30% lower odds of depression. In addition, individuals in the top tertile of existential well-being had a 70% lower odds of depression compared to individuals in the bottom tertile. Contrary to our original hypotheses, however, higher levels of religious well-being were associated with 1.5 times higher odds of depression.

Religious and existential well-being may be differentially associated with likelihood of depression. Given the complex interactions between religiosity and spirituality dimensions in relation to risk of major depression, the reliance on a single domain measure of religiosity or spirituality (e.g. religious service attendance) in research or clinical settings is discouraged.

Most mortality studies of psychiatric patients published to date have been conducted in hospital-based systems of care. This paper describes a study of the causes of death and associated risk factors among psychiatric patients who were followed up over a 20-year period in an area where psychiatric care is entirely provided by community-based psychiatric services.

All subjects in contact with the South Verona Community-based Mental Health Service (CMHS) over a 20-year period with an ICD-10 psychiatric diagnosis were included. Of these 6956 patients, 938 died during the study period. Standardized mortality ratios (SMRs) and Poisson multiple regressions were used to assess the excess of mortality in the sample compared with the general population.

The overall SMR of the psychiatric patients was 1.88. Mortality was significantly high among out-patients [SMR 1.71, 95% confidence interval (CI) 1.6–1.8], and higher still following the first admission (SMR 2.61, 95% CI 2.4–2.9). The SMR for infectious diseases was higher among younger patients and extremely high in patients with diagnoses of drug addiction (216.40, 95% CI 142.5–328.6) and personality disorders (20.87, 95% CI 5.2–83.4).

This study found that psychiatric patients in contact with a CMHS have an almost twofold higher mortality rate than the general population. These findings demonstrate that, since the closure of long-stay psychiatric hospitals, the physical health care of people with mental health problems is often neglected and clearly requires greater attention by health-care policymakers, services and professionals.

Continuity of care is considered by patients and clinicians an essential feature of good quality care in long-term disorders, yet there is general agreement that it is a complex concept. Most policies emphasize it and encourage systems to promote it. Despite this, there is no accepted definition or measure against which to test policies or interventions designed to improve continuity. We aimed to operationalize a multi-axial model of continuity of care and to use factor analysis to determine its validity for severe mental illness.

A multi-axial model of continuity of care comprising eight facets was operationalized for quantitative data collection from mental health service users using 32 variables. Of these variables, 22 were subsequently entered into a factor analysis as independent components, using data from a clinical population considered to require long-term consistent care.

Factor analysis produced seven independent continuity factors accounting for 62.5% of the total variance. These factors, Experience and Relationship, Regularity, Meeting Needs, Consolidation, Managed Transitions, Care Coordination and Supported Living, were close but not identical to the original theoretical model.

We confirmed that continuity of care is multi-factorial. Our seven factors are intuitively meaningful and appear to work in mental health. These factors should be used as a starting-point in research into the determinants and outcomes of continuity of care in long-term disorders.

The authors used results from a 20-year, high-intensity follow-up to measure the influence of ageing, and of age at onset, on the long-term persistence of symptoms in major depressive disorder (MDD).

Subjects who completed a 20-year series of semi-annual and then annual assessments with a stable diagnosis of MDD or schizo-affective disorder other than mainly schizophrenic (n=220) were divided according to their ages at intake into youngest (18–29 years), middle (30–44 years) and oldest (>45 years) groups. Depressive morbidity was quantified as the proportion of weeks spent in major depressive or schizo-affective episodes. General linear models then tested for effects of time and time×group interactions on these measures. Regression analyses compared the influence of age of onset and of current age.

Analyses revealed no significant time or group×time effects on the proportions of weeks in major depressive episodes in any of the three age groups. Earlier ages of onset were associated with greater symptom persistence, particularly in the youngest group. The proportions of weeks ill showed intra-individual stability over time that was most evident in the oldest group.

These results indicate that the persistence of depressive symptoms in MDD does not change as individuals move from their third to their fifth decade, from their fourth to their sixth decade, or from their sixth to their eighth decade. An early age of onset, rather than youth per se, is associated with greater morbidity over two decades.

Understanding the pathways to psychiatric care and recognition of delay points are crucial for the development of interventions that aim to improve access to mental health-care services.

Over a 2-month period in 2003, a total of 1044 patients at the commencement of new episodes of care at Amanuel Specialized Mental Hospital in Addis Ababa, Ethiopia were interviewed using the encounter form that was developed by the World Health Organization (WHO) for the study of pathways to psychiatric care.

The mental hospital was contacted directly by 41% of patients. The remaining patients sought care from up to four different caregivers before arriving at the psychiatric hospital. Where the initial service was not received at the psychiatric hospital, 30.9% of patients sought care from priests/holy water/church. The median delay between onset of illness and arrival at the psychiatric hospital was 38 weeks. The longest delays before arriving at the mental hospital were associated with having no formal education, joblessness, and diagnoses of epilepsy and physical conditions.

Implementing a robust referral system and establishing a strong working relationship with both traditional and modern health-care providers, as well as designing a service delivery model that targets particular segments of the population, such as those who are uneducated, jobless and/or suffer from epilepsy and somatic conditions, should be the most important strategies towards improving mental health service delivery and shortening of undue delay for patients receiving psychiatric care in Ethiopia.

There may be important public health implications of increasing our knowledge of factors associated with age of dementia onset. The pre-morbid personality domain of Neuroticism constituted an interesting and theoretically plausible, yet uninvestigated, candidate for such an association. We aimed to examine whether midlife Neuroticism was associated with earlier age of onset of Alzheimer's disease (AD).

This was a case–comparison study of 213 patients with probable AD. Detailed clinical information was collected for all patients including age of onset of dementia symptoms. One or two knowledgeable informants rated each patient's midlife personality retrospectively using the Neuroticism, Extraversion, Openness Five-Factor Inventory (NEO-FFI) questionnaire. The relationship between midlife Neuroticism and age of dementia onset was evaluated using both correlational analysis and backward linear regression analysis.

Midlife Neuroticism predicted younger age of dementia onset in females but not in males. The association found in females was independent of pre-morbid history of affective disorder.

This finding and its potential mechanism warrant further investigation.

Functional brain abnormalities have been repeatedly demonstrated in schizophrenia but there is little data concerning their progression. For such studies to have credibility it is first important to establish the reproducibility of functional imaging techniques. The current study aimed to examine these factors in healthy controls and in unmedicated subjects at high genetic risk of the disorder: (i) to examine the reproducibility of task-related activation patterns, (ii) to determine if there were any progressive functional changes in high-risk subjects versus controls reflecting inheritance of the schizophrenic trait, and (iii) to examine changes over time in relation to fluctuating positive psychotic symptoms (i.e. state effects).

Subjects were scanned performing the Hayling sentence completion test on two occasions 18 months apart. Changes in activation were examined in controls and high-risk subjects (n=16, n=63). Reproducibility was assessed for controls and high-risk subjects who remained asymptomatic at both time points (n=16, n=32).

Intra-class correlation values indicated good agreement between scanning sessions. No significant differences over time were seen between the high-risk and control group; however, comparison of high-risk subjects who developed symptoms versus those who remained asymptomatic revealed activation increases in the left middle temporal gyrus (p=0.026).

The current results suggest that functional changes over time occur in the lateral temporal cortex as high genetic risk subjects become symptomatic, further, they indicate the usefulness of functional imaging tools for investigating progressive changes associated with state and trait effects in schizophrenia.

The extant major psychiatric classifications, DSM-IV and ICD-10, are purportedly atheoretical and largely descriptive. Although this achieves good reliability, the validity of a medical diagnosis is greatly enhanced by an understanding of both risk factors and clinical history. In an effort to group mental disorders on the basis of risk factors and clinical manifestations, five clusters have been proposed. The purpose of this paper is to consider the position of bipolar disorder (BPD), which could be either with the psychoses, or with emotional disorders, or in a separate cluster.

We reviewed the literature on BPD, unipolar depression (UPD) and schizophrenia in relation to 11 validating criteria proposed by the DSM-V Task Force Study Group, and then summarized similarities and differences between BPD and schizophrenia on the one hand, and UPD on the other.

There are differences, often substantial and never trivial, for 10 of the 11 validators between BPD and UPD. There are also important differences between BPD and schizophrenia.

BPD has previously been classified together with UPD, but this is the least justifiable place for it. If it is to be recruited to a ‘psychotic cluster’, there are several important respects in which it differs from schizophrenia, so the cluster would have a division within it. The alternative would be to allow it to be in an intermediate position in a cluster of its own.

Depressive disorders are known to often be chronic and recurrent both in the general population and in psychiatric settings. However, despite its importance for public health and services, the outcome of depression in primary care is not well known.

In The Vantaa Primary Care Depression Study (PC-VDS), 1111 consecutive primary-care patients were screened for depression with the Prime-MD screen, and 137 diagnosed with DSM-IV depressive disorders by interviewing with the Structured Clinical Interview for DSM-IV (SCID)-I/P and SCID-II. This cohort was prospectively followed-up at 3, 6 and 18 months. Altogether 123 patients (90%) completed the 18-month follow-up, including 79 with major depressive disorder (MDD) and 44 with subsyndromal disorders. Duration of the index episode and the timing of relapses/recurrences were examined using a life-chart.

Of the patients with MDD, only a quarter [25% (20/79)] achieved and remained in full remission, while another quarter [25% (20/79)] persisted in major depressive episode for 18 months. The remaining 49% (39/79) suffered from residual symptoms or recurrences. In Cox regression models, time to remission and recurrences were robustly predicted by severity of depression, and less consistently by co-morbid substance-use disorder, chronic medical illness or cluster C personality disorder. Of the subsyndromal patients, 25% (11/44) proceeded to MDD.

This prospective medium-term study verified the high rate of recurrences and chronicity of depression also in primary care. Severity of depressive symptoms and co-morbidity are important predictors of outcome. Development of chronic disease management for depression is warranted in primary care.

Individuals with Down's syndrome (DS) are at high risk of developing Alzheimer's disease (AD). However, few studies have investigated brain anatomy in DS individuals with AD.

We compared whole brain anatomy, as measured by volumetric magnetic resonance imaging (MRI), in DS individuals with and without AD. We also investigated whether volumetric differences could reliably classify DS individuals according to AD status. We used volumetric MRI and manual tracing to examine regional brain anatomy in 19 DS adults with AD and 39 DS adults without AD.

DS individuals with AD had significantly smaller corrected volumes bilaterally of the hippocampus and caudate, and right amygdala and putamen, and a significantly larger corrected volume of left peripheral cerebrospinal fluid (CSF), compared to DS individuals without AD. The volume of the hippocampus and caudate nucleus correctly categorized 92% and 92% respectively of DS individuals without AD, and 75% and 80% respectively of DS individuals with AD.

DS individuals with AD have significant medial temporal and striatal volume reductions, and these may provide markers of clinical AD.

A proper understanding of patterns of care represents a crucial step in improving clinical decision making and enhancing service provision. Only a few studies, however, have explored global patterns of psychiatric admissions nationwide, and none have been undertaken in Italy.

Sociodemographic, clinical and treatment-related information was collected for 1577 patients admitted to 130 public and 36 private in-patient facilities in Italy during an index period in the year 2004. All patients were also rated using the 24-item Brief Psychiatric Rating Scale (BPRS) and the Personal and Social Performance (PSP) rating scales.

Non-affective psychoses (36%) were the most common diagnoses and accounted to a large extent for compulsory admissions. Private facilities were more likely to admit patients with organic mental disorders and substance abuse/dependence and less likely to admit patients with non-affective psychoses. Overall, 77.8% of patients had been receiving treatment by a mental health professional in the month prior to admission. In 54% of cases, the admission was solicited by patients' family members. The main factors preceding admission were impairment in work or social functioning, social withdrawal, and conflict with family members. Agitation, delusions and/or hallucinations, and the presence of multiple problems were associated with compulsory admissions, whereas depressive and anxiety symptoms were associated with voluntary admissions.

In a mixed, public–private psychiatric care system, like the Italian one, public and private facilities admit patients with widely different clinical characteristics and needs. Family support represents an important resource for most patients, and interventions specifically addressed to relieving family burden are warranted.

Evidence suggests that repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex (DLPFC) might be a promising new treatment procedure for depression. However, underlying working mechanisms of this technique are yet unclear. Multiple sessions of rTMS may – apart from the reported antidepressant effects – cause primary improvements in attentional control over emotional information, modulated by changes in cortical brain excitability within stimulated prefrontal regions.

In two experiments, we examined the temporary effects of high-frequency (HF) rTMS (10 Hz) applied over the left and right DLPFC on the attentional processing of emotional information and self-reported mood within samples of healthy volunteers.

The present study showed that one session of HF-rTMS over the right DLPFC produces instant impairments in the ability to inhibit negative information, in line with a characteristic cognitive vulnerability found in depressive pathology, whereas HF-rTMS of the left DLPFC did not lead to significant changes in attentional control. These effects could not be attributed to mood changes.

The findings of the present study may suggest a specific involvement of the right DLPFC in the attentional processing of emotional information.

Whether autism spectrum maps onto a spectrum of brain abnormalities and whether Asperger's syndrome (ASP) is distinct from high-functioning autism (HFA) are debated. White-matter maldevelopment is associated with autism and disconnectivity theories of autism are compelling. However, it is unknown whether children with ASP and HFA have distinct white-matter abnormalities.

Voxel-based morphometry mapped white-matter volumes across the whole brain in 91 children. Thirty-six had autism spectrum disorder. A history of delay in phrase speech defined half with HFA; those without delay formed the ASP group. The rest were typically developing children, balanced for age, IQ, gender, maternal language and ethnicity. White-matter volumes in HFA and ASP were compared and each contrasted with controls.

White-matter volumes around the basal ganglia were higher in the HFA group than ASP and higher in both autism groups than controls. Compared with controls, children with HFA had less frontal and corpus callosal white matter in the left hemisphere; those with ASP had less frontal and corpus callosal white matter in the right hemisphere with more white matter in the left parietal lobe.

HFA involved mainly left hemisphere white-matter systems; ASP affected predominantly right hemisphere white-matter systems. The impact of HFA on basal ganglia white matter was greater than ASP. This implies that aetiological factors and management options for autism spectrum disorders may be distinct. History of language acquisition is a potentially valuable marker to refine our search for causes and treatments in autism spectrum.

DSM-IV cites <85% of expected body weight (EBW) as a guideline for the diagnosis of anorexia nervosa (AN) but does not require a specific method for calculating EBW. The purpose of the present study was to determine the degree to which weight cut-off calculations vary across studies, and to evaluate whether differential cut-offs lead to discrepancies in the prevalence of individuals who are eligible for the AN diagnosis.

Two coders independently recorded the EBW calculation methods from 99 studies that either (a) compared individuals with AN to those with subclinical eating disorders or (b) conducted AN treatment trials. Each weight cut-off was applied to a nationally representative (n=12001) and treatment-seeking (n=189) sample to determine the impact of EBW calculation on the proportion who met the AN weight criterion.

Coders identified 10 different EBW methods, each of which produced different weight cut-offs for the diagnosis of AN. Although only 0.23% of the national sample met the lowest cut-off, this number increased 43-fold to 10.10% under the highest cut-off. Similarly, only 48.1% of treatment seekers met the lowest cut-off, whereas 89.4% met the highest.

There is considerable variance across studies in the determination of the AN weight cut-off. Discrepancies substantially affect the proportion of individuals who are eligible for diagnosis, treatment and insurance reimbursement. However, differences may not be fully appreciated because the ubiquitous citation of the 85% criterion creates a sense of false consensus.

Little is known about the effects of adult attention deficit hyperactivity disorder (ADHD) on work performance or accidents-injuries.

A survey was administered in 2005 and 2006 to employees of a large manufacturing firm to assess the prevalence and correlates of adult ADHD. Respondents (4140 in 2005, 4423 in 2006, including 2656 in both surveys) represented 35–38% of the workforce. ADHD was assessed with the World Health Organization (WHO) Adult ADHD Self-Report Scale (ASRS), a validated screening scale for DSM-IV adult ADHD. Sickness absence, work performance and workplace accidents-injuries were assessed with the WHO Health and Work Performance Questionnaire (HPQ).

The estimated current prevalence (standard error) of DSM-IV ADHD was 1.9% (0.4). ADHD was associated with a 4–5% reduction in work performance (χ12=9.1, p=0.001), a 2.1 relative-odds of sickness absence (χ12=6.2, p=0.013), and a 2.0 relative-odds of workplace accidents-injuries (χ12=5.1, p=0.024). The human capital value (standard error) of the lost work performance associated with ADHD totaled US$4336 (676) per worker with ADHD in the year before interview. No data were available to monetize other workplace costs of accidents-injuries (e.g. destruction of equipment). Only a small minority of workers with ADHD were in treatment.

Adult ADHD is a significantly impairing condition among workers. Given the low rate of treatment and high human capital costs, in conjunction with evidence from controlled trials that treatment can reduce ADHD-related impairments, ADHD would seem to be a good candidate for workplace trials that evaluate treatment cost-effectiveness from the employer's perspective.

Depression is a frequent mood disorder that affects around 33% of stroke patients and has been associated with both poorer outcome and increased mortality. Our aim was to test the possible association between inflammatory and neurotrophic molecular markers and the development of post-stroke depression.

We studied 134 patients with a first episode of ischemic stroke without previous history of depression or speech disorders. We screened for the existence of major depression symptoms in accordance with DSM-IV criteria and a Yesavage Geriatric Depression Scale (GDS) score >11 at discharge and 1 month after stroke. At these times, serum levels of molecular markers of inflammation [interleukin (IL)−1β, IL-6, intracellular adhesion molecule 1 (ICAM-1), tumor necrosis factor (TNF)-α, leptin and high-sensitivity C-reactive protein (hs-CRP)] and neurotrophic factors [brain-derived neurotrophic factor (BDNF)] were measured by enzyme-linked immunosorbent assay (ELISA).

Twenty-five patients (18.7%) were diagnosed as having major depression at discharge. Out of 104 patients who completed the follow-up period, 23 were depressed at 1 month (22.1%). Patients with major depression showed higher serum leptin levels at discharge [43.4 (23.4–60.2) v. 6.4 (3.7–16.8) ng/ml, p<0.001] and at 1 month after stroke [46.2 (34.0–117.7) v. 6.4 (3.4–12.2) ng/ml, p<0.001). Serum levels of leptin >20.7 ng/ml were independently associated with post-stroke depression [odds ratio (OR) 16.4, 95% confidence interval (CI) 5.2–51.5, p<0.0001]. Leptin levels were even higher in the eight patients who developed depression after discharge [114.6 (87.6–120.2) v. 7.2 (3.6–13.6) ng/ml, p<0.0001].

Serum leptin levels at discharge are found to be associated with post-stroke depression and may predict its development during the next month.

Calendar calculation is the ability to quickly name the day that a given date falls on. Previous research has suggested that savant calendar calculation is based on rote memory and the use of rule-based arithmetic skills. The objective of this study was to identify the cognitive processes that distinguish calendar calculation in savant individuals from healthy calendar calculators.

Savant calendar calculators with autism (ACC, n=3), healthy calendar calculators (HCC, n=3), non-savant subjects with autism (n=6) and healthy calendar calculator laymen (n=18) were included in the study. All participants calculated dates of the present (current month). In addition, ACC and HCC also calculated dates of the past and future 50 years.

ACC showed shorter reaction times and fewer errors than HCC and non-savant subjects with autism, and significantly fewer errors than healthy calendar calculator laymen when calculating dates of the present. Moreover, ACC performed faster and more accurate than HCC regarding past dates. However, no differences between ACC and HCC were detected for future date calculation.

The findings may imply distinct calendar calculation strategies in ACC and HCC, with HCC relying on calendar regularities for all types of dates and an involvement of (rote) memory in ACC when processing dates of the past and the present.

Prior studies have suggested unique patterns of neural activity associated with compulsive hoarding. However, to date no studies have examined the process of making actual decisions about whether to keep or discard possessions in patients with hoarding symptoms. An increasing body of clinical data and experimental psychopathology research suggests that hoarding is associated with impaired decision making; therefore, it is important to understand the neural underpinnings of decision-making abnormalities in hoarding patients.

Twelve adult patients diagnosed with compulsive hoarding, 17% of whom also met criteria for obsessive–compulsive disorder (OCD), and 12 matched healthy controls underwent functional magnetic resonance imaging (fMRI) while making decisions about whether or not to discard personal paper items (e.g. junk mail) brought to the laboratory as well as control items that did not belong to them. Items were either saved or destroyed following each decision.

When deciding about whether to keep or discard personal possessions, compulsive hoarding participants displayed excessive hemodynamic activity in lateral orbitofrontal cortex and parahippocampal gyrus. Among hoarding participants, decisions to keep personal possessions were associated with greater activity in superior temporal gyrus, middle temporal gyrus, medial frontal gyrus, anterior cingulate cortex, precentral gyrus, and cerebellum than were decisions to discard personal possessions.

These results provide partial support for an emerging model of compulsive hoarding based on complications of the decision-making process. They also suggest that compulsive hoarding may be characterized by focal deficits in the processing of reward and changes in reward contingencies, particularly when these are perceived to be punishing.

This study examined the prevalence of non-suicidal self-injury (NSSI), suicide attempts, suicide threats and suicidal ideation in a German school sample and compared the rates with a similar sample of adolescents from the midwestern USA by using cross-nationally validated assessment tools.

Data were provided from 665 adolescents (mean age 14.8 years, s.d.=0.66, range 14–17 years) in a school setting. Students completed the Self-Harm Behavior Questionnaire (SHBQ), the Ottawa Self-Injury Inventory (OSI) and a German version of the Center for Epidemiological Studies–Depression Scale (CES-D).

A quarter of the participants (25.6%) endorsed at least one act of NSSI in their life, and 9.5% of those students answered that they had hurt themselves repetitively (more than four times). Forty-three (6.5%) of the students reported a history of a suicide attempt. No statistically significant differences were observed between the German and US samples in terms of self-injury or suicidal behaviors.

By using the same validated assessment tools, no differences were found in the prevalence and characteristics of self-injury and suicidal behaviors between adolescents from Germany and the USA. Thus, it seems that NSSI has to be understood as worldwide phenomenon, at least in Western cultures.
