Lifetime History Of Psychiatric Disorders Research Articles

Subjects suffering from bipolar disorder taking lithium are less likely to report physical pain: a FACE-BD study.

Physical pain is a common issue in people with bipolar disorder (BD). It worsens mental health and quality of life, negatively impacts treatment response, and increases the risk of suicide. Lithium, which is prescribed in BD as a mood stabilizer, has shown promising effects on pain. This naturalistic study included 760 subjects with BD ( FACE-BD cohort) divided in two groups: with and without self-reported pain (evaluated with the EQ-5D-5L questionnaire). In this sample, 176 subjects were treated with lithium salts. The objectives of the study were to determine whether patients receiving lithium reported less pain, and whether this effect was associated with the recommended mood-stabilizing blood concentration of lithium. Subjects with lithium intake were less likely to report pain (odds ratio [OR]=0.59, 95% confidence interval [CI], 0.35-0.95; p=0.036) after controlling for sociodemographic variables, BD type, lifetime history of psychiatric disorders, suicide attempt, personality traits, current depression and anxiety levels, sleep quality, and psychomotor activity. Subjects taking lithium were even less likely to report pain when lithium concentration in blood was ≥0.5mmol/l (OR=0.45, 95% CI, 0.24-0.79; p=0.008). This is the first naturalistic study to show lithium's promising effect on pain in subjects suffering from BD after controlling for many confounding variables. This analgesic effect seems independent of BD severity and comorbid conditions. Randomized controlled trials are needed to confirm the analgesic effect of lithium salts and to determine whether lithium decreases pain in other vulnerable populations.

Specificity of affective dynamics of bipolar and major depressive disorder.

Here, we examine whether the dynamics of the four dimensions of the circumplex model of affect assessed by ecological momentary assessment (EMA) differ among those with bipolar disorder (BD) and major depressive disorder (MDD). Participants aged 11-85years (n=362) reported momentary sad, anxious, active, and energetic dimensional states four times per day for 2weeks. Individuals with lifetime mood disorder subtypes of bipolar-I, bipolar-II, and MDD derived from a semistructured clinical interview were compared to each other and to controls without a lifetime history of psychiatric disorders. Random effects from individual means, inertias, innovation (residual) variances, and cross-lags across the four affective dimensions simultaneously were derived from multivariate dynamic structural equation models. All mood disorder subtypes were associated with higher levels of sad and anxious mood and lower energy than controls. Those with bipolar-I had lower average activation, and lower energy that was independent of activation, compared to MDD or controls. However, increases in activation were more likely to perpetuate in those with bipolar-I. Bipolar-II was characterized by higher lability of sad and anxious mood compared to bipolar-I and controls but not MDD. Compared to BD and controls, those with MDD exhibited cross-augmentation of sadness and anxiety, and sadness blunted energy. Bipolar-I is more strongly characterized by activation and energy than sad and anxious mood. This distinction has potential implications for both specificity of intervention targets and differential pathways underlying these dynamic affective systems. Confirmation of the longer term stability and generalizability of these findings in future studies is necessary.

Neurobiological sensitivity to unpredictable threat and familial risk for the internalizing and externalizing spectra in adolescents.

Adolescence is a key developmental period for the emergence of psychiatric disorders. However, there is still no consensus on the core mechanisms of dysfunction in youth. Neurobiological sensitivity to unpredictable threat has been associated with several psychiatric disorders in adults. The present study examined adolescent defensive motivation (startle reflex) and attention (event-related potentials) in anticipation of unpredictable threat in relation to both adolescent and maternal (i.e. familial risk) internalizing and externalizing spectra. The sample included 395 15-year-old adolescents and their biological mothers. Adolescent startle potentiation and probe P300 suppression (indicating increased attention to threat) were measured in anticipation of predictable and unpredictable threat. Adolescent and maternal lifetime history of psychiatric disorders were assessed via semi-structured diagnostic interviews, and confirmatory factor analysis was used to model internalizing and externalizing spectra. The adolescent internalizing spectrum was positively associated with adolescent startle potentiation and probe P300 suppression to unpredictable threat. Conversely, the adolescent externalizing spectrum was negatively associated with adolescent P300 suppression to unpredictable threat. The maternal internalizing spectrum was positively associated with adolescent startle potentiation to unpredictable threat and P300 suppression to both predictable and unpredictable threat. The maternal externalizing spectrum was negatively associated with adolescent startle potentiation to unpredictable threat and P300 suppression to both predictable and unpredictable threat. Adolescent and maternal internalizing and externalizing spectra were independently related to adolescent startle potentiation and P300 suppression. Adolescent neurobiological sensitivity to unpredictable threat is associated with both personal history and familial risk for the internalizing and externalizing spectra.

Neuropsychiatric and Cognitive Comorbidities in Epilepsy.

This article discusses psychiatric and cognitive comorbidities of epilepsy over the lifespan and illustrates opportunities to improve the quality of care of children and adults with epilepsy. One in 3 people with epilepsy have a lifetime history of psychiatric disorders, and they represent an important prognostic marker of epilepsy. Contributors are diverse and display a complex relationship. Cognitive comorbidities are also common among those living with epilepsy and are increasingly recognized as a reflection of changes to underlying brain networks. Among the cognitive comorbidities, intellectual disability and dementia are common and can complicate the diagnostic process when cognitive and/or behavioral features resemble seizures. Comorbidities require consideration from the first point of contact with a patient because they can determine the presentation of symptoms, responsiveness to treatment, and the patient's day-to-day functioning and quality of life. In epilepsy, psychiatric and cognitive comorbidities may prove a greater source of disability for the patient and family than the seizures themselves, and in the case of essential comorbidities, they are regarded as core to the disorder in terms of etiology, diagnosis, and treatment.

Psychiatric History and Overactive Bladder Symptom Severity in Ambulatory Urogynecological Patients.

Introduction and hypothesis: A link between psychiatric comorbidities and overactive bladder symptomatology has been suggested by preclinical and clinical studies. Given this, we hypothesized that a psychiatric history and current treatment with psychotropic medications could be related to the severity of overactive bladder and incontinence symptoms in patients referred to a tertiary care urogynecological center. Methods: One hundred and twenty-seven female patients diagnosed with an overactive bladder were screened for a lifetime history of psychiatric disorders and the type and number of psychotropic medications currently taken. The overall severity of overactive bladder symptoms was assessed using the Indevus Urgency Severity Scale. The severity and impact of urinary incontinence on the quality of life were quantified with the International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form. Urinary incontinence was further quantified with the aid of the Urinary Distress Inventory-6. The patients were screened for stress urinary incontinence using the Stamey Incontinence Score. Results: A psychiatric history, as well as current use of at least two psychotropic medications, was associated with increased severity of overactive bladder symptoms. A history of depression and current treatment with any selective serotonin reuptake inhibitor was associated with increased severity of stress urinary incontinence symptoms. Current treatment with other psychotropic medications, including sedative-hypnotics and drugs with anticholinergic properties was not related to the severity of overactive bladder and incontinence symptoms.

Mortality in patients with psychogenic nonepileptic seizures.

To investigate the hypothesis that patients diagnosed with psychogenic nonepileptic seizures (PNES) on video-EEG monitoring (VEM) have increased mortality by comparison to the general population. This retrospective cohort study included patients evaluated in VEM units of 3 tertiary hospitals in Melbourne, Australia, between January 1, 1995, and December 31, 2015. Diagnosis was based on consensus opinion of experienced epileptologists and neuropsychiatrists at each hospital. Mortality was determined in patients diagnosed with PNES, epilepsy, or both conditions by linkage to the Australian National Death Index. Lifetime history of psychiatric disorders in PNES was determined from formal neuropsychiatric reports. A total of 5,508 patients underwent VEM. A total of 674 (12.2%) were diagnosed with PNES, 3064 (55.6%) with epilepsy, 175 (3.2%) with both conditions, and 1,595 (29.0%) received other diagnoses or had no diagnosis made. The standardized mortality ratio (SMR) of patients diagnosed with PNES was 2.5 (95% confidence interval [CI] 2.0-3.3). Those younger than 30 had an 8-fold higher risk of death (95% CI 3.4-19.8). Direct comparison revealed no significant difference in mortality rate between diagnostic groups. Among deaths in patients diagnosed with PNES (n = 55), external causes contributed 18%, with 20% of deaths in those younger than 50 years attributed to suicide, and "epilepsy" was recorded as the cause of death in 24%. Patients diagnosed with PNES have a SMR 2.5 times above the general population, dying at a rate comparable to those with drug-resistant epilepsy. This emphasizes the importance of prompt diagnosis, identification of risk factors, and implementation of appropriate strategies to prevent potential avoidable deaths.

COGNITION AND LATE-LIFE SUICIDE: COGNITIVE PROFILES AMONG DEPRESSED SUICIDAL SUBGROUPS AS A FUNCTION OF MEDICAL SERIOUSNESS AND ONSET OF SUICIDAL BEHAVIOR

Introduction Depressed older adults are at high-risk for suicidal behavior (Pfeiffer et al., 2013, Vannoy et al., 2007) and for developing dementia (Kaup et al, 2016; Mizra et al., 2016). Executive dysfunction has been described across the life-span in suicide attempters (Keilp et al., 2013, Clark et al., 2011, Richards-Devantoy et al., 2012). However, few studies have explored the links between several domains of cognition and suicide risk in those with late-life depression and the extant evidence is equivocal at best (Conejero et al., 2018, Tu et al., 2018, Erlangsen et al., 2008). Suicidal behavior is heterogeneous, and it is unclear whether the medical seriousness (Beck et al., 1975) of the suicide attempt or whether the onset of first suicidal behavior (initiated earlier in life relative to late-life (60+ years)) relates differently to cognitive deficits. Methods This project uses a case-control design and includes 278 adults aged 50?years and older: 56 non-depressed controls (no life-time history of psychiatric disorder), 67 non-suicidal depressed older adults(no life-time history of suicide ideation or suicide attempt), 63 depressed suicide ideators, and 92 depressed adults with a history of suicide attempt. Analysis 1 examined cognitive profiles of low (n=52) vs. high-lethality (i.e., potentially fatal without medical intervention) (n=40) suicide attempters relative to non-suicidal depressed older adults and non-depressed controls. Analysis 2 examined cognitive profiles of those making their first suicide attempt prior to age 60 (early onset: n=66) and those making their first suicide attempt at or after age 60 (late-onset: n=26) relative to non-suicidal depressed older adults and non-depressed controls. Lethality of attempt was similarly distributed across early- and late-onset attempters. Depression severity was assessed using the Hamilton Depression Rating Scale (HAM-D-17 minus the suicide item). Cognitive functioning was assessed using the Repeatable Battery of Neuropsychological Status (RBANS) and the Trail Making Test from the Delis Kaplan Executive Functioning System (D-KEFS). Linear mixed effects models were used for assessing group differences cognitive domains assessed using multiple subtests or trials (i.e., learning and memory) and linear regression was used for cognitive domains assessed using a single test (i.e., processing speed, executive functioning). Demographic covariates were used for all data analyses (i.e., age, sex, education). Analyses comparing suicidal subgroups with non-suicidal depressed older adults additionally adjusted for depression severity and lifetime history of anxiety and substance use disorders. Results High-lethality attempters performed worse than low-lethality attempters and non-depressed controls on measures of verbal memory (Linear mixed effects model; group x test interaction: F=1.997, p=0.03). On a measure of executive functioning, low- but not high-lethality attempters performed worse than non-suicidal depressed older adults (LL: Beta= -0.18, p=0.01; HL: Beta=-0.12, p=0.08) and non-depressed controls (LL: Beta=0.31, p Conclusions Cognitive profiles of older suicidal attempters varied based on the lethality of most lethal suicide attempt and age of first suicide attempt. Those with low-lethality and early-onset suicide attempts exhibited executive dysfunction relative to non-suicidal depressed older adults, in-line with previous findings indicating executive dysfunction as part of life-long suicide vulnerability factors. In contrast, late-onset attempters exhibited slower processing speed relative to non-suicidal depressed older adults, and high-lethality attempters performed worse on memory measures relative to low-lethality attempters, possibly indicating a dementia prodrome.

Frequency and correlates of mother-infant bonding disorders among postpartum women in India.

Disorders of mother-infant bonding have been described since early 20th Century. Previous studies have looked at the prevalence of bonding disorders among mothers with postpartum psychiatric disorders. However, its frequency among healthy postpartum mothers is less studied. Two hundred and fifty mother-infant dyads were studied using the Mini International Neuropsychiatric Interview (MINI), the Stafford Interview, Bangalore Maternal Behaviour Scale (BMBS) and Tamil versions of the Edinburgh Postnatal Depression Scale (EPDS) and the Postpartum Bonding Questionnaire (PBQ). The mothers were interviewed between 4 weeks to six months postpartum. In addition, thirty one mothers with a lifetime history of psychiatric disorders were interviewed using the above scales. The frequency of bonding disorders was found to be 24% among healthy postpartum mothers as against 45.2% in mothers with psychiatric disorder. However, the frequency of mild disorders of bonding was relatively lower at 5.6% among healthy mothers and 6.5% among mothers with psychiatric disorders. We found that mothers in India had a clinging / over-involved subtype of anxiety that prevented them from leaving their baby under care of another competent adult. While infant-related anxiety was seen in 10% of healthy mothers, about 20% of mothers with psychiatric diagnoses had anxiety. The presence of bonding disorders was not correlated with any maternal or infant related factors except difficulty in breastfeeding. Disorders of mother infant bonding are seen in healthy postpartum mothers. The frequency of mild disorders of bonding appears to be similar across countries and this condition warrants further attention.

Is psychopathology elevated in Big-C visual artists and scientists?

The idea that psychopathology is associated with exceptional creativity has persisted despite a paucity of corroborating or disconfirming evidence. The authors measured psychopathology, including schizotypal personality traits, social responsiveness/autism spectrum traits, and lifetime incidence of mental disorders, along with lab-based tests of creativity in a unique sample of Big-C (exceptionally creative) individuals. The authors examined Big-C visual artists (VIS; n = 35), Big-C scientists (SCI; n = 41), and a smart comparison group (SCG; n = 31) matched on age, sex, race/ethnicity, parental education, and estimated IQ. Neither lifetime nor current prevalence of mental disorders was higher in Big-C groups relative to either the SCG or epidemiologic estimates, but individuals without a lifetime history of psychiatric disorder scored higher on a test of creative cognition relative to those who had at least one lifetime diagnosis. The groups differed in self-reported symptoms: VIS reported more schizotypal features than both SCI and SCG, and higher levels of socially divergent traits than SCI. Self-reported symptoms were below diagnostic thresholds in all 3 groups. The findings indicate that neither exceptional creativity nor performance on tests that putatively assess creativity are associated with mental illness but suggest that certain schizotypal features and socially divergent traits-at subclinical levels-are associated with Big-C achievement, at least in visual artists. The findings further raise questions about the sensitivity of laboratory tests for Big-C cognition. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Un ou plusieurs syndromes somatiques fonctionnels ? Comparaison de l’état de santé de personnes fibromyalgiques et électro-hypersensibles

IntroductionFunctional somatic syndromes, grouping somatic symptoms without an organic explanation, are defined either by their predominant symptoms or by an attribution to an, often hypothetical, cause. Due to many similarities, some authors consider that there is only one FSS due to a general phenomenon of “somatization”. The objective of this work was to compare two functional somatic syndromes, one defined by its symptoms, fibromyalgia, and the other by a specific contested attribution, electro-hypersensitivity. MethodFibromyalgia or electro-hypersensitive participants (EHS) were recruited from September 2016 to April 2017 through associations of patients in Auvergne-Rhône-Alpes. Home interviews included the collection of medical, psychopathological, and symptom histories. The assessment of psychological distress, quality of life and the search for other functional somatic syndromes was performed through structured questionnaires, self-administrated scales, and clinical examination. ResultsSixteen fibromyalgia subjects and sixteen EHS subjects were included. There are differences in symptomatology, although many symptoms are common to both conditions. Lifetime history of psychiatric disorders and current psychological distress and psychopathology are frequent in both groups but more prevalent in fibromyalgia subjects. The experience of the symptoms, their interpretation, the diagnostic itineraries and the therapeutic behaviours differ radically according to the group, even if for all socio-professional impact is high and quality of life are altered. ConclusionThe health status of fibromyalgia persons is overall worse than the health status of electro-hypersensitive individuals in this small sample. Despite the overlap in symptoms and a similar impact on daily functioning, this exploratory study suggests that heterogeneous mechanisms of “somatization” may be at stake in functional somatic syndromes.

Prevalence and Screening of Mental Illness among Remand Prisoners in Hong Kong

This study aimed to validate the Correctional Mental Health Screen (CMHS) in the Hong Kong prison population and determine the prevalence of psychiatric disorders among remand prisoners in Hong Kong and the associated factors of mental illness. This cohort study was conducted at the Lai Chi Kok Reception Centre and the Tai Lam Centre for Women in Hong Kong. Remand prisoners aged ≥21 years were recruited between May and August 2014. Sociodemographic and clinical data were collected. Each remand prisoner was assessed using the appropriate CMHS for males or for females, then interviewed by a specialist psychiatrist using the Structured Clinical Interview for DSM-IV for current affective disorder and psychotic disorder for cross-validation. A total of 245 remand prisoners were recruited (150 males and 95 females; mean age, 25.8 years). Of them, 51% (55% males and 44% females) had a lifetime history of psychiatric disorder, whereas 39.6% (46% males and 29.5% females) had a current psychiatric disorder. The most common psychiatric disorder was substance use disorder (>36%), followed by mood disorder (>20%), psychotic disorder (5.3%), and lifetime neurotic disorder (3.7%). Living in a public housing estate (odds ratio [OR] = 1.99), a history of childhood conduct problem (OR = 2.40), and a forensic history (OR = 1.97) were associated with an increased risk of having a psychiatric disorder. The CMHS had good diagnostic efficiency after cross-validation with the Structured Clinical Interview for DSM-IV. Psychiatric disorders are prevalent in remand prisoners in Hong Kong. The CMHS is an effective tool to screen remand prisoners for timely treatment of prisoners with mental health needs.

Telomere Length in Newborns is Related to Maternal Stress During Pregnancy.

Telomere length (TL) is a marker of biological aging, and numerous studies have shown associations between TL and somatic or psychiatric disorders. Research also indicates an association between maternal stress during pregnancy and TL in the offspring. The present study investigated possible associations between TL and: (1) maternal perceived stress during pregnancy; (2) a maternal lifetime history of psychiatric disorder (lifetime PD); and (3) paternal age. TL was analyzed in 319 newborns and 318 mothers from a predominantly Caucasian sample (n=273 Caucasian newborns and n=274 Caucasian mothers). Two key findings were observed. First, maternal perceived stress during pregnancy was associated with shorter telomeres in newborns but not with maternal TL. Second, maternal lifetime PD was associated with shorter maternal telomeres, but not with TL in newborns. Paternal age was not associated with TL in newborns. The finding that maternal stress during pregnancy is associated with shorter telomeres in newborns supports the results of smaller previous studies. The fact that a relation between maternal prenatal stress and TL was observed in the offspring but not in mothers may be attributable to a high vulnerability to stress during intrauterine development of a maturing organism. To our knowledge, this is the largest study to date to show that maternal stress during pregnancy but not maternal lifetime PD is associated with shorter telomeres in the offspring.

The prevalence, age distribution and comorbidity of personality disorders in Australian women.

We aimed to describe the prevalence and age distribution of personality disorders and their comorbidity with other psychiatric disorders in an age-stratified sample of Australian women aged ⩾25 years. Individual personality disorders (paranoid, schizoid, schizotypal, histrionic, narcissistic, borderline, antisocial, avoidant, dependent, obsessive-compulsive), lifetime mood, anxiety, eating and substance misuse disorders were diagnosed utilising validated semi-structured clinical interviews (Structured Clinical Interview for DSM-IV-TR Axis I Disorders, Research Version, Non-patient Edition and Structured Clinical Interview for DSM-IV Axis II Personality Disorders). The prevalence of personality disorders and Clusters were determined from the study population ( n = 768), and standardised to the Australian population using the 2011 Australian Bureau of Statistics census data. Prevalence by age and the association with mood, anxiety, eating and substance misuse disorders was also examined. The overall prevalence of personality disorders in women was 21.8% (95% confidence interval [CI]: 18.7, 24.9). Cluster C personality disorders (17.5%, 95% CI: 16.0, 18.9) were more common than Cluster A (5.3%, 95% CI: 3.5, 7.0) and Cluster B personality disorders (3.2%, 95% CI: 1.8, 4.6). Of the individual personality disorders, obsessive-compulsive (10.3%, 95% CI: 8.0, 12.6), avoidant (9.3%, 95% CI: 7.1, 11.5), paranoid (3.9%, 95% CI: 3.1, 4.7) and borderline (2.7%, 95% CI: 1.4, 4.0) were among the most prevalent. The prevalence of other personality disorders was low (⩽1.7%). Being younger (25-34 years) was predictive of having any personality disorder (odds ratio: 2.36, 95% CI: 1.18, 4.74), as was being middle-aged (odds ratio: 2.41, 95% CI: 1.23, 4.72). Among the strongest predictors of having any personality disorder was having a lifetime history of psychiatric disorders (odds ratio: 4.29, 95% CI: 2.90, 6.33). Mood and anxiety disorders were the most common comorbid lifetime psychiatric disorders. Approximately one in five women was identified with a personality disorder, emphasising that personality disorders are relatively common in the population. A more thorough understanding of the distribution of personality disorders and psychiatric comorbidity in the general population is crucial to assist allocation of health care resources to individuals living with these disorders.

Physical health comorbidities in women with personality disorder: Data from the Geelong Osteoporosis Study

BackgroundAssociations between common psychiatric disorders, psychotic disorders and physical health comorbidities are frequently investigated. The complex relationship between personality disorders (PDs) and physical health is less understood, and findings to date are varied. This study aims to investigate associations between PDs with a number of prevalent physical health conditions. MethodsThis study examined data collected from women (n=765;≥25years) participating in a population-based study located in south-eastern Australia. Lifetime history of psychiatric disorders was assessed using the semi-structured clinical interviews (SCID-I/NP and SCID-II). The presence of physical health conditions (lifetime) were identified via a combination of self-report, medical records, medication use and clinical data. Socioeconomic status, and information regarding medication use, lifestyle behaviors, and sociodemographic information was collected via questionnaires. Logistic regression models were used to investigate associations. ResultsAfter adjustment for sociodemographic variables (age, socioeconomic status) and health-related factors (body mass index, physical activity, smoking, psychotropic medication use), PDs were consistently associated with a range of physical health conditions. Novel associations were observed between Cluster A PDs and gastro-oesophageal reflux disease (GORD); Cluster B PDs with syncope and seizures, as well as arthritis; and Cluster C PDs with GORD and recurrent headaches. ConclusionsPDs were associated with physical comorbidity. The current data contribute to a growing evidence base demonstrating associations between PDs and a number of physical health conditions independent of psychiatric comorbidity, sociodemographic and lifestyle factors. Longitudinal studies are now required to investigate causal pathways, as are studies determining pathological mechanisms.

Relationships of perceived public stigma of mental illness and psychosis-like experiences in a non-clinical population sample.

Studies on the association between psychopathology, perceived public stigma, and labeling in mental illness have focused primarily on severe but rare mental disorders, especially schizophrenia, or other clinically defined psychotic disorders. Although evidence is mounting that psychosis-like experiences show high prevalence in the general population and lead to an increased risk of psychotic disorders, little is known about how psychosis-like experiences independently affect perceived public stigma in the non-clinical population. The aim of the present study was to examine the relationship between psychosis-like experiences and perceived public stigma in a non-clinical sample. For this cross-sectional study, we recruited 524 individuals (239 male, 285 female) who had no lifetime history of psychiatric disorder. Participants completed questionnaires that asked for sociodemographic and clinical information, a measure of perceived public stigma (Perceived Psychiatric Stigma Scale [PPSS]), and two measures of psychosis-like experiences (Peters et al. Delusions Inventory [PDI]; Cardiff Anomalous Perceptions Scale [CAPS]). Of the sociodemographic characteristics analyzed in this study-gender, age, education level, marital status, and religion-only age simultaneously influenced PPSS, PDI, and CAPS scores. As hypothesized, perceived public stigma was positively correlated with measures of psychosis-like experiences, even after controlling for age. Furthermore, the perceived stigma was more strongly associated with delusion proneness than with anomalous perceptual experiences. The association between psychopathology and perceived public stigma appears to extend beyond clinically defined psychosis to more common psychosis-like experiences in a sample drawn from the general Han Chinese population.

Substance use and psychiatric disorders in Irish adolescents: a cross-sectional study of patients attending substance abuse treatment service

Little information exists on the levels of psychiatric disorders among substance abusing adolescents in Ireland. The aim of the study is examine the pattern of psychiatric disorders and explore for gender differences among adolescents with a substance use disorder (SUD) in Ireland. A cross-sectional descriptive study and retrospective review of medical records on the 144 most recent admissions at the Youth Drug and Alcohol (YoDA) service, Dublin was carried out. Overall, 48% of the patients had a lifetime history of psychiatric disorders. Deliberate self-harm (DSH) was the most common condition (27.1%), followed by attention deficit hyperactivity disorder (20.8%) and depression (10.4%). Conduct disorder and oppositional defiant disorder were infrequently diagnosed. Compared with boys, the girls were more likely to have a lifetime history of psychiatric disorders (odds ratio 3.7; p = 0.005). These findings provide the first prevalence data on psychiatric disorders in a clinically representative sample of I...

Impaired sleep quality and sleep duration in smokers—results from the German Multicenter Study on Nicotine Dependence

Cigarette smoking is a severe health burden being related to a number of chronic diseases. Frequently, smokers report about sleep problems. Sleep disturbance, in turn, has been demonstrated to be involved in the pathophysiology of several disorders related to smoking and may be relevant for the pathophysiology of nicotine dependence. Therefore, determining the frequency of sleep disturbance in otherwise healthy smokers and its association with degree of nicotine dependence is highly relevant. In a population-based case-control study, 1071 smokers and 1243 non-smokers without lifetime Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Axis I disorder were investigated. Sleep quality (SQ) of participants was determined by the Pittsburgh Sleep Quality Index. As possible confounders, age, sex and level of education and income, as well as depressiveness, anxiety, attention deficit hyperactivity, alcohol drinking behaviour and perceived stress, were included into multiple regression analyses. Significantly more smokers than non-smokers (28.1% versus 19.1%; P < 0.0001) demonstrated a disturbed global SQ. After controlling for the confounders, impaired scores in the component scores of sleep latency, sleep duration and global SQ were found significantly more often in smokers than non-smokers. Consistently, higher degrees of nicotine dependence and intensity of smoking were associated with shorter sleep duration. This study demonstrates for the first time an elevated prevalence of sleep disturbance in smokers compared with non-smokers in a population without lifetime history of psychiatric disorders even after controlling for potentially relevant risk factors. It appears likely that smoking is a behaviourally modifiable risk factor for the occurrence of impaired SQ and short sleep duration.

Waiting to win: elevated striatal and orbitofrontal cortical activity during reward anticipation in euthymic bipolar disorder adults

Bipolar disorder may be characterized by a hypersensitivity to reward-relevant stimuli, potentially underlying the emotional lability and dysregulation that characterizes the illness. In parallel, research highlights the predominant role of striatal and orbitofrontal cortical (OFC) regions in reward-processing and approach-related affect. We aimed to examine whether bipolar disorder, relative to healthy, participants displayed elevated activity in these regions during reward processing. Twenty-one euthymic bipolar I disorder and 20 healthy control participants with no lifetime history of psychiatric disorder underwent functional magnetic resonance imaging (fMRI) scanning during a card-guessing paradigm designed to examine reward-related brain function to anticipation and receipt of monetary reward and loss. Data were collected using a 3T Siemens Trio scanner. Region-of-interest analyses revealed that bipolar disorder participants displayed greater ventral striatal and right-sided orbitofrontal [Brodmann area (BA) 11] activity during anticipation, but not outcome, of monetary reward relative to healthy controls (p < 0.05, corrected). Whole-brain analyses indicated that bipolar disorder, relative to healthy, participants also displayed elevated left-lateral OFC (BA 47) activity during reward anticipation (p < 0.05, corrected). Elevated ventral striatal and OFC activity during reward anticipation may represent a neural mechanism for predisposition to expansive mood and hypo/mania in response to reward-relevant cues that characterizes bipolar disorder. Our findings contrast with research reporting blunted activity in the ventral striatum during reward processing in unipolar depressed individuals, relative to healthy controls. Examination of reward-related neural activity in bipolar disorder is a promising research focus to facilitate identification of biological markers of the illness.

Home foreclosure and risk of psychiatric morbidity during the recent financial crisis

A defining feature of the US economic downturn of 2008-2010 was the alarming rate of home foreclosure. Although a substantial number of US households have experienced foreclosure since 2008, the effects of foreclosure on mental health are unknown. We examined the effects of foreclosure on psychiatric symptomatology in a prospective, population-based community survey. Data were drawn from the Detroit Neighborhoods and Health Study (DNHS), waves 1 and 2 (2008-2010). A probability sample of predominantly African-American adults in Detroit, Michigan participated (n=1547). We examined the association between home foreclosure between waves 1 and 2 and increases in symptoms of DSM-IV major depression and generalized anxiety disorder (GAD). The most common reasons for foreclosure were an increase in monthly payments, an increase in non-medical expenses and a reduction in family income. Exposure to foreclosure between waves 1 and 2 predicted symptoms of major depression and GAD at wave 2, controlling for symptoms at wave 1. Even after adjusting for wave 1 symptoms, sociodemographics, lifetime history of psychiatric disorder at wave 1 and exposure to other financial stressors between waves 1 and 2, foreclosure was associated with an increased rate of symptoms of major depression [incidence density ratio (IDR) 2.4, 95% confidence interval (CI) 1.6-3.6] and GAD (IDR 1.9, 95% CI 1.4-2.6). We provide the first prospective evidence linking foreclosure to the onset of mental health problems. These results, combined with the high rate of home foreclosure since 2008, suggest that the foreclosure crisis may have adverse effects on the mental health of the US population.

Perinatal complications in unaffected sisters of anorexia nervosa patients: testing a covariation model between genetic and environmental factors

Although perinatal complications are hypothesized to be risk factors for the development of anorexia nervosa (AN), no study to date explored this issue using a discordant sibling design. This type of design allows to explore whether the risk for obstetric complications is itself a consequence of the genetic vulnerability for AN (covariation model) or whether obstetric complications increase the risk of AN independently of (additive model), or in interaction with (interaction model), the disorder's genetic liability. The presence of perinatal complications was assessed through review of the obstetric records of 60 AN subjects, 60 unaffected sisters, and 70 healthy subjects. Unaffected sisters and healthy controls were compared in relation to perinatal characteristics and complications. There was no evidence for an elevated rate of complications in unaffected siblings of AN patients. Mothers with a positive psychiatric history tended to have more perinatal complications. Perinatal complications seem to be independent risk factors that may interact with, but are not caused by, familial risk factors for AN. In terms of prevention, a particular attention should be paid to mothers with a lifetime history of psychiatric disorders.
