Abstract
OBJECTIVE We examined the relative contribution of parental bipolar disorder (BPD) and psychiatric comorbidities (disruptive behavior disorders [DBD] and anxiety disorders) in predicting psychiatric symptoms and disorders in 2-5-year-old offspring. METHODS Participants were 60 families with a parent with BPD and 78 offspring and 70 comparison families in which neither parent had a mood disorder and 91 offspring. Parent and offspring diagnoses and symptoms were assessed using standardized diagnostic interviews and measures, with offspring assessors masked to parental diagnoses. RESULTS Offspring of parents with BPD had significant elevations in behavioral, mood and anxiety disorders and symptoms. Both parental BPD and DBD contributed to elevations in child disruptive behavioral symptoms, whereas child anxiety symptoms were more strongly predicted by comorbid parental anxiety. Parental BPD was a stronger predictor than comorbid DBD of child DBDs. CONCLUSION Some of the elevated risk for disorders in preschoolers is accounted for by parental comorbidity.

Abstract
BACKGROUND Attention Deficit Disorder / Hyperactivity (ADHD) and Bipolar Disorder (BD) are highly comorbid disorders. Studies have raised the hypothesis of shared genetic, neurobiological, and clinical factors. This would entail an excess risk of co-occurrence of both disorders. OBJECTIVE We present the first meta-analysis of individual and familial associations between ADHD and BD. METHODS From 2688 references, 59 were included, with a total of 550,379 ADHD patients, 57,799 BD patients and 12,608,137 controls. RESULTS Personal history of ADHD increased the risk of BD (OR = 6.06), and conversely individuals with BD had an increased risk of ADHD (OR = 8.94). First-degree relatives of ADHD patients had an increased risk of BD (OR = 1.94). Offspring of individuals with BD had a higher risk for ADHD (OR = 2.33). Finally, first-degree relatives of BD patients had an increased risk of ADHD (OR = 2.71). CONCLUSION We show a clear epidemiological overlap between ADHD and BD, as well as a strong familial association which advocates in favor of a more systematic screening.

Abstract
Our present understanding of bowel and bladder control has changed dramatically with the introduction of functional imagining technologies such as PET, SPECT, fMRI scanning, and near-infrared spectroscopy of the brain. Urologists tend to see control of urination and defecation as processes that occurred at or below the level of the pons for the most part. In this chapter, we examine the control of storing and emptying of urine and stool from what will be a more neurocentric perspective, integrating the frontal lobes into the process and moving beyond the pons on which most of the literature has focused in the past. Utilizing this approach gives us a better understanding of why there is an overlapping of neuropsychiatric problems in many patients with voiding dysfunction.

Abstract
OBJECTIVE Attention deficit hyperactivity disorder is a frequent comorbid condition in adults with bipolar disorder. We performed a meta-analysis aimed at assessing sociodemographic and clinical correlates of attention deficit hyperactivity disorder in bipolar disorder. METHOD We searched main electronic databases up to June 2021. Random-effects meta-analyses, with relevant meta-regression and quality-based sensitivity analyses, were carried out to estimate the association between attention deficit hyperactivity disorder and putative correlates, grading the quality of evidence. RESULTS We included 43 studies, based on 38 independent samples. Attention deficit hyperactivity disorder participants were more likely to be males (odds ratio = 1.46; p < 0.001) and unemployed (odds ratio = 1.45; p = 0.045), and less likely to be married (odds ratio = 0.62; p = 0.014). They had an earlier onset of bipolar disorder (standardized mean difference = -0.36; p < 0.001); more mood episodes (standardized mean difference = 0.35; p = 0.007), particularly depressive (standardized mean difference = 0.30; p = 0.011) and mixed (standardized mean difference = 0.30; p = 0.031) ones; higher odds of using antidepressants (odds ratio = 1.80; p = 0.024) and attempted suicides (odds ratio = 1.83; p < 0.001) and lower odds of psychotic features (odds ratio = 0.63; p = 0.010). Moreover, they were more likely to have generalized anxiety disorder (odds ratio = 1.50; p = 0.019), panic disorder (odds ratio = 1.89; p < 0.001), social phobia (odds ratio = 1.61; p = 0.017), eating disorders (odds ratio = 1.91; p = 0.007), antisocial personality disorder (odds ratio = 3.59; p = 0.004) and substance (odds ratio = 2.29; p < 0.001) or alcohol (odds ratio = 2.28; p < 0.001) use disorders. Quality of the evidence was generally low or very low for the majority of correlates, except for bipolar disorder onset and alcohol/substance use disorders (high), and suicide attempts (moderate). CONCLUSION Comorbid bipolar disorder/attention deficit hyperactivity disorder may have some distinctive clinical features including an earlier onset of bipolar disorder and higher comorbid alcohol/substance use disorder rates. Further research is needed to identify additional clinical characteristics of this comorbidity.

Abstract
Attention-deficit / hyperactivity disorder (ADHD) and Bipolar Disorder (BD) are common mental disorders with a high degree of comorbidity. However, no systematic review with meta-analysis has aimed to quantify the degree of comorbidity between both disorders. To this end we performed a systematic search of the literature in October 2020. In a meta-analysis of 71 studies with 646,766 participants from 18 countries, it was found that about one in thirteen adults with ADHD was also diagnosed with BD (7.95 %; 95 % CI: 5.31-11.06), and nearly one in six adults with BD had ADHD (17.11 %; 95 % CI: 13.05-21.59 %). Substantial heterogeneity of comorbidity rates was present, highlighting the importance of contextual factors: Heterogeneity could partially be explained by diagnostic system, sample size and geographical location. Age of BD onset occurred earlier in patients with comorbid ADHD (3.96 years; 95 % CI: 2.65-5.26, p < 0.001). Cultural and methodological differences deserve attention for evaluating diagnostic criteria and clinicians should be aware of the high comorbidity rates to prevent misdiagnosis and provide optimal care for both disorders.

Abstract
Studies have consistently reported an increased prevalence of psychiatric comorbidity (PC) in individuals with neurodevelopmental disorders (NDDs) compared with typically developing controls, with high rates of anxiety disorders in autism spectrum disorders and challenging behaviors in children and adolescent with intellectual disability. Psychiatric assessment in this population should include multiple sources of information, derived from multiple contexts and using multiple methods, with accurate detection of contributing and trigger factors. It is important to focus on detecting change from the child's baseline functioning and to use, when possible, ad hoc instruments for assessing PC in the NDD population. Modifications in the setting and assessment procedures should be scheduled based on the child's age, developmental level, and sensory sensitivities. Simultaneously, validated screening instruments, which dimensionally assess the symptomatology of several NDDs and psychiatric disorders, are warranted to not only assist in the identification of PCs in NDDs but also discriminate among different NDDs. Changes from DSM-IV-TR to DSM-5 have had an impact on the diagnosis of several disorders in children and adolescents and, subsequently, on the current diagnostic tools, requiring appropriate and prompt modifications of the available instruments.

Abstract
Objective: Our aim is to investigate the impact of childhood ADHD comorbidity on the clinical features of obsessive compulsive disorder (OCD). Method: Ninety-five adult outpatients with a diagnosis of OCD were assessed by using the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version, ADHD module, and the Yale-Brown Obsessive Compulsive Scale. Patients with or without childhood ADHD were compared in terms of the sociodemographic and clinical features, psychiatric comorbidities, and rating scales. Results: The rate of episodic course of OCD (p < .001), religious and sexual obsessions (p = .009, p = .020, respectively), lifetime comorbidity of bipolar disorder (BD), social anxiety disorder (SAD; p = .001, p = .009, respectively), and tic disorder (TD) comorbidity (p < .001) were higher in the OCD + ADHD group than in the OCD without ADHD group. Conclusion: Childhood ADHD may be associated with higher rates of BD, SAD, and TD comorbidity and episodic course of OCD as well as higher frequency of certain types of obsessions.

Abstract
OBJECTIVE To examine development of bipolar spectrum disorders (BPSD) and other disorders in prospectively followed children with attention-deficit/hyperactivity disorder (ADHD). METHOD In the Longitudinal Assessment of Manic Symptoms (LAMS) study, 531 of 685 children age 6-12 (most selected for scores > 12 on General Behavior Inventory 10-item Mania scale) had ADHD, 112 with BPSD, and 419 without. With annual assessments for 8 years, retention averaged 6.2 years. Chi-square analyses compared rate of new BPSD and other comorbidity between those with versus without baseline ADHD and between retained versus resolved ADHD diagnosis. Cox regression tested factors influencing speed of BPSD onset. RESULTS Of 419 with baseline ADHD but not BPSD, 52 (12.4%) developed BPSD, compared with 16 of 110 (14.5%) without either baseline diagnosis. Those who developed BPSD had more nonmood comorbidity over the follow-up than those who did not develop BPSD (p = .0001). Of 170 who still had ADHD at eight-year follow-up (and not baseline BPSD), 26 (15.3%) had developed BPSD, compared with 16 of 186 (8.6%) who had ADHD without BPSD at baseline but lost the ADHD diagnosis (χ2 = 3.82, p = .051). There was no statistical difference in whether ADHD persisted or not across new BPSD subtypes (χ2 = 1.62, p = .446). Of those who developed BPSD, speed of onset was not significantly related to baseline ADHD (p = .566), baseline anxiety (p = .121), baseline depression (p = .185), baseline disruptive behavior disorder (p = .184), age (B = -.11 p = .092), maternal mania (p = .389), or paternal mania (B = .73, p = .056). Those who started with both diagnoses had more severe symptoms/impairment than those with later developed BPSD and reported having ADHD first. CONCLUSIONS In a cohort selected for symptoms of mania at age 6-12, baseline ADHD was not a significant prospective risk factor for developing BPSD. However, persistence of ADHD may marginally mediate risk of BPSD, and early comorbidity of both diagnoses increases severity/impairment.

Abstract
BACKGROUND Studying the phenotypic manifestations of increased genetic liability for Bipolar Disorder (BD) can increase understanding of this disorder. AIMS We assessed whether genetic risk for BD was associated with childhood psychopathology and features of hypomania in young adulthood within a large population-based birth cohort. METHODS We used data from the second Psychiatric Genetics Consortium Genome Wide Association Study (GWAS) for Bipolar Disorder to construct a polygenic risk score (PRS) for each individual in the Avon Longitudinal Study of Parents and Children (ALSPAC). Linear and logistic regression models were used to assess associations between the BD-PRS and emotional/behavioural difficulties, attention deficit hyperactivity disorder (ADHD) and borderline personality disorder (BPD) traits in childhood, as well as hypomania in early adulthood (sample sizes from 2654 to 6111). RESULTS The BD-PRS was not associated with total hypomania score, but was weakly associated with a binary measure of hypomania (OR = 1.13, 95%CI 0.98,1.32; p = 0.097), and particularly at higher hypomania symptom thresholds (strongest evidence OR = 1.33, 95%CI 1.07, 1.65; p = 0.01). The BD-PRS was also associated with ADHD (OR = 1.31, 95%CI 1.10, 1.57; p = 0.018), but not with other childhood psychopathology. LIMITATIONS The PRS only captures common genetic variation and currently explains a relatively small proportion of the variance for BD. CONCLUSIONS The BD-PRS was associated with ADHD in childhood, and weakly with adult hypomania, but not with other psychopathology examined. Our findings suggest that genetic risk for BD does not appear to manifest in childhood to the same extent as schizophrenia genetic risk has been reported to do.

Abstract
BACKGROUND Identifying clinical features that predict conversion to bipolar disorder (BD) in those at high familial risk (HR) would assist in identifying a more focused population for early intervention. METHOD In total 287 participants aged 12-30 (163 HR with a first-degree relative with BD and 124 controls (CONs)) were followed annually for a median of 5 years. We used the baseline presence of DSM-IV depressive, anxiety, behavioural and substance use disorders, as well as a constellation of specific depressive symptoms (as identified by the Probabilistic Approach to Bipolar Depression) to predict the subsequent development of hypo/manic episodes. RESULTS At baseline, HR participants were significantly more likely to report ⩾4 Probabilistic features (40.4%) when depressed than CONs (6.7%; p < .05). Nineteen HR subjects later developed either threshold (n = 8; 4.9%) or subthreshold (n = 11; 6.7%) hypo/mania. The presence of ⩾4 Probabilistic features was associated with a seven-fold increase in the risk of 'conversion' to threshold BD (hazard ratio = 6.9, p < .05) above and beyond the fourteen-fold increase in risk related to major depressive episodes (MDEs) per se (hazard ratio = 13.9, p < .05). Individual depressive features predicting conversion were psychomotor retardation and ⩾5 MDEs. Behavioural disorders only predicted conversion to subthreshold BD (hazard ratio = 5.23, p < .01), while anxiety and substance disorders did not predict either threshold or subthreshold hypo/mania. CONCLUSIONS This study suggests that specific depressive characteristics substantially increase the risk of young people at familial risk of BD going on to develop future hypo/manic episodes and may identify a more targeted HR population for the development of early intervention programs.

Individuals with bipolar spectrum disorder (BSD) frequently meet criteria for comorbid anxiety disorders, and anxiety may be an important factor in the etiology and course of BSDs. The current study examined the association of lifetime anxiety disorders with prospective manic/hypomanic versus major depressive episodes. Participants were 244 young adults (aged 17-26) with milder forms of BSDs (i.e., bipolar-II, cyclothymia, BD-NOS). First, bivariate analyses assessed differences in baseline clinical characteristics between participants with and without DSM-IV anxiety diagnoses. Second, negative binomial regression analyses tested whether lifetime anxiety predicted number of manic/hypomanic or major depressive episodes developed during the study. Third, survival analyses evaluated whether lifetime anxiety predicted time to onset of manic/hypomanic and major depressive episodes. Results indicated that anxiety history was associated with greater illness severity at baseline. Over follow-up, anxiety history predicted fewer manic/hypomanic episodes, but did not predict number of major depressive episodes. Anxiety history also was associated with longer time to onset of manic/hypomanic episodes, but shorter time to onset of depressive episodes. Findings corroborate past studies implicating anxiety disorders as salient influences on the course of BSDs. Moreover, results extend prior research by indicating that anxiety disorders may be linked with reduced manic/hypomanic phases of illness.

Abstract
BACKGROUND There is limited understanding of the symptomatic development of bipolar disorder from childhood to early adulthood. AIMS We assessed whether borderline personality disorder traits, ADHD, and emotional, behavioural and social difficulties during childhood were associated with hypomania assessed in young adulthood. METHOD We used data from the Avon Longitudinal Study of Parents and Children (ALSPAC), to examine associations between measures of childhood psychopathology and lifetime hypomanic features assessed at age 22-23 years using the Hypomania Checklist-32 (HCL-32; n = 3372). We also conducted a factor analysis of the HCL to identify latent constructs underlying hypomania, and the extent to which childhood psychopathology was associated with these. RESULTS We identified two factors of the HCL corresponding to energy/mood and risk-taking/irritability. There was evidence of association between childhood borderline personality disorder traits and both hypomania factors, with evidence that the association was stronger with the risk-taking/irritability factor. All individual borderline traits, with the exception of fear of abandonment, were associated with hypomania. There was also evidence of association between most other measures of childhood psychopathology (ADHD, hyperactivity, conduct problems, peer relationship problems and reduced prosocial behaviour) and the risk-taking/irritability factor, but much less consistent evidence of association with the energy/mood factor. LIMITATIONS The HCL cannot diagnose bipolar disorder and may be subject to reporting bias. CONCLUSIONS A broad range of childhood psychopathologies may represent early markers of risk for hypomania. Further studies are required to understand the mechanisms underlying these associations, and to inform earlier detection of bipolar disorder.

Abstract
BACKGROUND We aimed to outline the early risk factors for adult bipolar disorder (BPD) in adolescents with mood disorders. METHODS Adolescents (16-17 years old) with mood disorders (n = 287; 90 participants with hypomania spectrum episodes and 197 with major depressive disorder [MDD]) were identified from a community sample. Fifteen years later (at 30-33 years of age), mood episodes were assessed (n = 194). The risk of developing BPD (n = 22), compared with MDD (n = 104) or no mood episodes in adulthood (n = 68), was estimated via logistic regression. Adolescent mood symptoms, non-mood disorders, and family characteristics were assessed as potential risk factors. RESULTS Among the adolescents with mood disorders, a family history of BPD was the strongest predictor of developing BPD compared with having no mood episodes in adulthood (OR = 5.94; 95% CI = 1.11-31.73), whereas disruptive disorders significantly increased the risk of developing BPD compared with developing MDD (OR = 2.94; CI = 1.06-8.12). The risk that adolescents with MDD would develop adult BPD, versus having no mood episodes in adulthood, was elevated among those with an early disruptive disorder (OR = 3.62; CI = 1.09-12.07) or multiple somatic symptoms (OR = 6.60; CI = 1.70-25.67). Only disruptive disorders significantly predicted adult BPD among adolescents with MDD versus continued MDD in adulthood (OR = 3.59; CI = 1.17-10.97). Only a few adolescents with hypomania spectrum episodes continued to have BPD as adults, and anxiety disorders appeared to increase this risk. CONCLUSIONS Although most of the identified potential risk factors are likely general predictors of continued mood disorders, disruptive disorders emerged as specific predictors of developing adult BPD among adolescents with MDD.

Abstract
Psychiatric disorders such as schizophrenia, bipolar disorder, major depressive disorder, attention-deficit/hyperactivity disorder and autism spectrum disorder are common and result in significant morbidity and mortality. Although currently classified into distinct disorder categories, they show clinical overlap and familial co-aggregation, and share genetic risk factors. Recent advances in psychiatric genomics have provided insight into the potential mechanisms underlying the overlap between these disorders, implicating genes involved in neurodevelopment, synaptic plasticity, learning and memory. Furthermore, evidence from copy number variant, exome sequencing and genome-wide association studies supports a gradient of neurodevelopmental psychopathology indexed by mutational load or mutational severity, and cognitive impairment. These findings have important implications for psychiatric research, highlighting the need for new approaches to stratifying patients for research. They also point the way for work aiming to advance our understanding of the pathways from genotype to clinical phenotype, which will be required in order to inform new classification systems and to develop novel therapeutic strategies.

Abstract
OBJECTIVE As initial episode type can predict later morbidity in bipolar disorder, we tested the hypothesis that clinical antecedents might predict initial episode types. METHOD We studied 263 first-episode, adult, DSM-IV-TR type I bipolar disorder (BD-I) subjects within the McLean-Harvard-International First-Episode Project. Based on blinded assessments of antecedents from SCID examinations and clinical records, we compared first lifetime manic vs. other (mixed, depressive, or non-affective) major psychotic episodes. RESULTS We identified 32 antecedents arising at early, intermediate or later times, starting 12.3±10.7 years prior to first lifetime major psychotic episodes. Based on multivariate modeling, antecedents associated significantly and independently with other (n=113) more than manic (n=150) first lifetime major psychotic episodes ranked by odds ratio: more early attentional disturbances, more late depression, more early perplexity, more detoxification, more early unstable mixed affects, more antidepressants, more early dysphoria, more intermediate depression, more early impulsivity, more late anhedonia, longer early-to-intermediate intervals, more intermediate substance abuse, more family history of major depression, and younger at earliest antecedents. Antecedents selectively preceding manic more than other first psychotic episodes included more late behavioral problems and more risk of familial BD-I. CONCLUSION Clinical antecedents in adult, BD-I patients, beginning a decade before first major episodes and progressing through sequential stages were dissimilar in manic vs. other first psychotic episodes.

Abstract
BACKGROUND We investigated whether adolescents with hypomania spectrum episodes have an excess risk of mental and physical morbidity in adulthood, as compared with adolescents exclusively reporting major depressive disorder (MDD) and controls without a history of adolescent mood disorders. METHODS A community sample of adolescents (N = 2 300) in the town of Uppsala, Sweden, was screened for depressive symptoms. Both participants with positive screening and matched controls (in total 631) were diagnostically interviewed. Ninety participants reported hypomania spectrum episodes (40 full-syndromal, 18 with brief episode, and 32 subsyndromal), while another 197 fulfilled the criteria for MDD without a history of a hypomania spectrum episode. A follow up after 15 years included a blinded diagnostic interview, a self-assessment of personality disorders, and national register data on prescription drugs and health services use. The participation rate at the follow-up interview was 71% (64/90) for the hypomania spectrum group, and 65.9% (130/197) for the MDD group. Multiple imputation was used to handle missing data. RESULTS The outcomes of the hypomania spectrum group and the MDD group were similar regarding subsequent non-mood Axis I disorders in adulthood (present in 53 vs. 57%). A personality disorder was reported by 29% of the hypomania spectrum group and by 20% of the MDD group, but a statistically significant difference was reached only for obsessive-compulsive personality disorder (24 vs. 14%). In both groups, the risk of Axis I disorders and personality disorders in adulthood correlated with continuation of mood disorder. Prescription drugs and health service use in adulthood was similar in the two groups. Compared with adolescents without mood disorders, both groups had a higher subsequent risk of psychiatric morbidity, used more mental health care, and received more psychotropic drugs. CONCLUSIONS Although adolescents with hypomania spectrum episodes and adolescents with MDD do not differ substantially in health outcomes, both groups are at increased risk for subsequent mental health problems. Thus, it is important to identify and treat children and adolescents with mood disorders, and carefully follow the continuing course.

Abstract
BACKGROUND The aim of this comparative study was to investigate the type and frequency of diagnoses preceding adult bipolar disorder (BD) and schizophrenia (SZ). METHODS A follow-back study of all preceding diagnoses in all patients aged 21-34 years with a primary, first time diagnosis of BD (N = 784) or SZ (N = 1667) in 2008 to 2010. Data were taken from the Danish Psychiatric Central Research Register (DPCRR) including ICD-10 and ICD-8 diagnoses. RESULTS The numbers of patients with any preceding diagnoses amounted to 69.3% in BD and 76.6% in SZ with affective disorders (excluding BD) being the most frequent preceding diagnosis (46.6 vs. 28.0%), followed by psychoses (PSY) other than SZ (14.2 vs. 41.5%, p < .001), and substance use disorders (SUD) (16.1 vs. 26.9%, p < .001). Reactions to severe stress were equally frequent in both samples (26.3 vs. 26.6%) as were personality disorders (21.8 vs. 22.4%) and ADHD (4.2 vs. 3.5%), whereas rates of conduct disorders (1.7 vs. 3.1%) were rather low in both samples. Very few of the preceding diagnoses had their onset in childhood and adolescence. Overall patients with SZ had a minor but statistically significant earlier onset of any psychiatric disorder compared to BD (mean age: 23.3 vs. 22.5, p < .001). Regression analyses indicated that BD was associated with an increased risk of having experienced preceding affective disorders and ADHD, while SZ was associated with an increased risk of preceding substance use disorders, psychosis, anxiety disorders, and personality disorders. CONCLUSIONS Specific developmental trajectories of preceding disorders were delineated for BD and SZ with affective disorders being more specific for BD and both SUD and PSY more specific to SZ. There are different patterns of vulnerability in terms of preceding diagnosis in young adults with BD and SZ.

Abstract
OBJECTIVE High comorbidity ratio of bipolar mood disorder (BMD) with Axis I and Axis II diagnoses is reported in the literature. The possible relationship between BMD and attention-deficit/hyperactivity disorder (ADHD) in all age groups has been attracting more attention of researchers due to highly overlapping symptoms such as excessive talking, attention deficit, and increased motor activity. In this study, we aimed to investigate the prevalence of ADHD comorbidity in BMD patients and the clinical features of these patients. METHODS Of 142 patients, who presented to the Bipolar Disorder Unit of Zonguldak Karaelmas University Research and Application Hospital between the dates of August 1, 2008 and June 31, 2009 and diagnosed with BMD according to DSM-IV criteria consecutively, 118 patients signed informed consent and 90 of them completed the study. They all were in euthymic phase during the study evaluations. A sociodemographical data form, Wender-Utah Rating Scale (WURS), ADD/ADHD Diagnostic and Evaluation Inventory for Adults, and Structural Clinical Interview for DSM-IV Axis I Disorders, Clinical Version (SCID-I) were applied to all participating patients. RESULTS A total of 23.3% of all patients met the criteria for A-ADHD diagnosis along BMD. No difference was detected regarding sociodemographical features between the BMD+A-ADHD and the BMD without A-ADHD groups. The BMD+A-ADHD group had at least one extra educational year repetition than the other group and the difference was statistically significant. The BMD starting age in the BMD+A-ADHD group was significantly earlier (p=0.044) and the number of manic episodes was more frequent in the BMD+A-ADHD group (p=0.026) than the BMD without ADHD group. Panic disorder in the BMD+A-ADHD group (p=0.019) and obsessive-compulsive disorder in the BMD+C-ADHD group (p=0.001) were most frequent comorbidities. CONCLUSIONS A-ADHD is a frequent comorbidity in BMD. It is associated with early starting age of BMD, higher number of manic episodes during the course of BMD, and more comorbid Axis I diagnoses.

Abstract
BACKGROUND Transgenerational association of bipolar spectrum disorder (BPSD) and attention deficit/hyperactivity disorder (ADHD) has been reported, but inconclusively. METHOD Children ages 6-12 were systematically recruited at first outpatient visit at 9 clinics at four universities and reliably diagnosed; 621 had elevated symptoms of mania (>12 on the Parent General Behavior Inventory 10-Item Mania Scale); 86 had scores below 12. We analyzed baseline data to test a familial association hypothesis: compared to children with neither BPSD nor ADHD, those with either BPSD or ADHD would have parents with higher rates of both bipolar and ADHD symptoms, and parents of comorbid children would have even higher rates of both. RESULTS Of 707 children, 421 had ADHD without BPSD, 45 BPSD without ADHD, 117 comorbid ADHD+BPSD, and 124 neither. The rate of parental manic symptoms was similar for the comorbid and BPSD-alone groups, significantly greater than for ADHD alone and "neither" groups, which had similar rates. ADHD symptoms in parents of children with BPSD alone were significantly less frequent than in parents of children with ADHD (alone or comorbid), and no greater than for children with neither diagnosis. Family history of manic symptoms, but not ADHD symptoms, was associated with parent-rated child manic-symptom severity over and above child diagnosis. LIMITATIONS The sample was not epidemiologic, parent symptoms were based on family history questions, and alpha was 0.05 despite multiple tests. CONCLUSIONS These results do not support familial linkage of BPSD and ADHD; they are compatible with heritability of each disorder separately with coincidental overlap.

[PMID: 22633181 DOI: 10.1016/j.jad.2012.04.003] [Citation(s) in RCA: 72] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/25/2011] [Revised: 04/05/2012] [Accepted: 04/05/2012] [Indexed: 12/12/2022]
Abstract
Diagnostic formulations for attention deficit hyperactivity disorder (ADHD) and bipolar disorder (BD) both include symptoms of distractibility, psychomotor agitation and talkativeness, alongside associated emotional features (irritability and emotional lability). Treatment studies suggest the importance of accurate delineation of ADHD and BD. However, boundaries between the two disorders are blurred by the introduction of broader conceptualisations of BD. This review attempts to elucidate whether associations between ADHD and BD are likely to be driven by superficial symptomatological similarities or by a more meaningful etiological relationship between the disorders. This is achieved by outlining findings on comorbidity, temporal progression of the disorders, familial co-variation, and neurobiology in ADHD and BD across the lifespan. Longitudinal studies fail to consistently show developmental trajectories between ADHD and BD. Comparative research investigating neurobiology is in its infancy, and although some similarities are seen between ADHD and BD, studies also emphasise differences between the two disorders. However, comorbidity and family studies appear to show that the two disorders occur together and aggregate in families at higher than expected rates. Furthermore close inspection of results from population studies reveals heightened co-occurrence of ADHD and BD even in the context of high comorbidity commonly noted in psychopathology. These results point towards a meaningful association between ADHD and BD, going beyond symptomatic similarities. However, future research needs to account for heterogeneity of BD, making clear distinctions between classical episodic forms of BD, and broader conceptualisations of the disorder characterised by irritability and emotional lability, when evaluating the relationship with ADHD.

Abstract
Functional lower urinary tract problems, bladder and bowel problems, or dysfunctional elimination syndrome are all terms that describe the common array of symptoms that include overactive bladder syndrome, voiding postponement, stress incontinence, giggle incontinence, and dysfunctional voiding in children. This article discusses the nomenclature and looks at the pathophysiology of functional bladder disorders from a different perspective than has been the norm in the past. Some standard medical treatments as well as some newer forms of treatment are outlined. Treatment algorithms for urinary frequency and urinary incontinence have been created to help the practitioner manage the patient.

Abstract
BACKGROUND 22q11.2 deletion syndrome (22qDS) is a common genetic disorder with highly variable clinical manifestations that may include depression, bipolar disorder and schizophrenia. Studies of psychiatric disorders in youth with 22qDS often had methodological limitations. This study reviewed clinical studies with the currently best available methodology to determine the occurrence of affective disorders compared to other psychiatric disorders in youth with 22qDS. METHOD A PubMed search was performed to identify psychiatric studies published from 2000 through 2009 of children and adolescents with genetically confirmed 22qDS who underwent systematic psychiatric assessments. Studies that met defined inclusion/exclusion criteria were selected for further analysis. RESULTS Seven studies with a total of 323 children and adolescents with 22qDS (mean age=10.8 years) met the defined inclusion/exclusion criteria. Depressive disorders, but not bipolar spectrum disorders, were increased compared to community-based rates in youth without 22qDS. Anxiety disorders and attention-deficit/hyperactivity disorder were the most frequent disorders. Although psychotic-like phenomena and schizotypical traits were reported, only two adolescents (<1%) had a psychotic disorder. LIMITATIONS Unknown selection and assessment factors may have impacted on occurrence rates. CONCLUSION The elevated occurrence of depressive, anxiety, and attention disorders in children with 22qDS, compared to community-based rates in children without 22qDS, suggest that psychiatric screening is needed. Longitudinal study is needed to determine if these childhood psychiatric disorders will resolve, continue into adulthood, or develop into more serious psychopathology.

Abstract
INTRODUCTION The diagnosis of bipolar disorder (BD) in youths has been controversial, especially for the subtype BD not otherwise specified (BD-NOS). In spite of growing evidence that sleep is a core feature of BD, few studies characterize and compare sleep disturbances in youth with BD type I (BD-I) and BD-NOS. Sleep disturbances are frequently reported in clinical descriptions of children and adolescents with BD, however the reporting of the frequency and characteristics of sleep symptoms in youth with BD-NOS and BD-I during episodes remain poor. This study compares symptom of sleep disturbance as occurring in manic and depressive episodes in BD-I and BD-NOS youth using Kiddie-schedule for affective disorders and schizophrenia, present and lifetime version (K-SADS-PL) interview data. The study also addresses whether symptoms of sleep disturbance vary in different age groups. MATERIALS AND METHODS The sample consisted of 70 children and adolescent outpatients at an urban specialty clinic (42M/28F, 10.8 ± 3.6 years old) including 24 BD-I and 46 BD-NOS assessed using K-SADS-PL-parent interview. RESULTS Sleep disturbances including insomnia and decreased need for sleep were reported by 84.3% of the sample. Enuresis was diagnosed in 27% of sample. There were no significant differences in frequency of sleep symptoms between BD-I and BD-NOS. Regardless of BD subtype, current functioning was negatively correlated with decreased need for sleep but not insomnia, and regardless of BD subtype. CONCLUSION The majority of youth with BD presents with sleep symptoms during mood episodes. BD-NOS presents with the same proportion of sleep symptoms as BD-I in our sample.

Abstract
This article reviews the literature that examines whether exposure to psychostimulants or antidepressants precipitates or exacerbates manic symptoms, or decreases the age at onset of mania in pediatric populations. A PubMed search using relevant key words identified studies targeting five distinct clinical groups: (i) youth without a diagnosis of bipolar disorder (BD) at the time of exposure to psychostimulants; (ii) youth with a diagnosis of BD at the time of exposure to psychostimulants; (iii) youth without a diagnosis of BD at the time of exposure to antidepressants; (iv) youth with a diagnosis of BD at the time of exposure to antidepressants; and (v) youth who develop BD after exposure to these medications. In patients with attention-deficit hyperactivity disorder (ADHD), the risk for mania was found to be relatively low with the use of psychostimulants. For patients with BD and ADHD, effective mood stabilization is important prior to adding a stimulant. For children with depression and/or anxiety, the risk of antidepressant-induced mania (AIM) was generally low (<2%), but the risk of general 'activation' secondary to a selective serotonin reuptake inhibitor (SSRI) may be greater (2-10%). However, rates of AIM in specialty clinics appear to be much higher. SSRIs may be particularly problematic in specific populations, such as those with some symptoms of mania or a family history of BD, but the precise risk is unknown. There is no clear evidence that stimulants or SSRIs accelerate the natural course of BD development in overall samples, but in individual cases prescribers should proceed cautiously when using these agents in youth already at risk for developing BD, such as those with ADHD and mood dysregulation, a history of prior AIM, a history of psychosis, or a family history of BD.

Abstract
BACKGROUND Identifying prodromal features that predate the onset of bipolar disorder (BD) may enable the prevention of BD and aid early intervention. This review addresses two key questions: Is there a bipolar prodrome? And, if there is, what are its characteristic features? METHOD A comprehensive search of databases (PubMed, Medline, EMBASE and PsycINFO) supplemented by hand searches was used to identify studies of symptoms preceding the onset of BD. RESULTS Fifty-nine studies were identified, of which 14 met inclusion criteria. Symptoms can predate the onset of BD by months to years and can be categorized as attenuated forms of BD symptoms, general symptoms common to a range of mental disorders, and personality traits, particularly cyclothymia. Two studies provided sufficient data to enable sensitivity and specificity to be calculated. Specificity of several of the features was high (>90%) but sensitivity was generally low (all <60%). We propose a model based on the findings in the studies reviewed to illustrate the potential trajectory to BD and the points at which it may be possible to intervene. CONCLUSIONS Clinical features preceding the onset of BD can be identified. However, conclusions about whether there is a distinct prodrome to BD are restricted by the limitations of current evidence. The high specificity of some features suggests they may be useful in clinical practice. Large-scale longitudinal studies are needed to validate these features and characterize their specificity and sensitivity in independent samples.

Abstract
OBJECTIVE To compare attention-deficit hyperactivity disorder (ADHD), bipolar spectrum disorders (BPSDs), and comorbidity in the Longitudinal Assessment of Manic Symptoms (LAMS) study. METHODS Children ages 6-12 were recruited at first visit to clinics associated with four universities. A BPSD diagnosis required that the patient exhibit episodes. Four hypotheses were tested: (i) children with BPSD + ADHD would have a younger age of mood symptom onset than those with BPSD but no ADHD; (ii) children with BPSD + ADHD would have more severe ADHD and BPSD symptoms than those with only one disorder; (iii) global functioning would be more impaired in children with ADHD + BPSD than in children with either diagnosis alone; and (iv) the ADHD + BPSD group would have more additional diagnoses. RESULTS Of 707 children, 421 had ADHD alone, 45 had BPSD alone, 117 had both ADHD and BPSD, and 124 had neither. Comorbidity (16.5%) was slightly less than expected by chance (17.5%). Age of mood symptom onset was not different between the BPSD + ADHD group and the BPSD-alone group. Symptom severity increased and global functioning decreased with comorbidity. Comorbidity with other disorders was highest for the ADHD + BPSD group, but higher for the ADHD-alone than the BPSD-alone group. Children with BPSD were four times as likely to be hospitalized (22%) as children with ADHD alone. CONCLUSIONS The high rate of BPSD in ADHD reported by some authors may be better explained as a high rate of both disorders in child outpatient settings rather than ADHD being a risk factor for BPSD. Co-occurrence of the two disorders is associated with poorer global functioning, greater symptom severity, and more additional comorbidity than for either single disorder.

Abstract
Early onset (pediatric) bipolar disorders are still an issue of much controversy due to several clinical particularities of the thymic episodes at this age. To date, there is indeed no consensus regarding the prevalence of bipolar disorders before puberty. Diagnosis criteria in children and young adolescents remain thus elusive. The purpose of this review is to provide an overview of this issue. The idea of continuity, from childhood to adulthood, in bipolar disorders also raises important questions regarding predictive factors of bipolar disorders in adults. Studies on the childhood of bipolar adults, as well as studies on the children of bipolar parents will be reviewed, in an attempt to identify the psychopathological substrates of bipolar disorders.

Abstract
BACKGROUND Recent studies have demonstrated high rates of psychopathology in the offspring of parents with bipolar disorder. The aim of this study was to identify psychiatric diagnoses in a sample of children of bipolar parents. METHOD This case series comprised 35 children and adolescents aged 6 to 17 years, with a mean age of 12.5 ± 2.9 years (20 males and 15 females), who had at least one parent with bipolar disorder type I. The subjects were assessed using the Schedule for Affective Disorders and Schizophrenia for School-Age Children - Present and Lifetime version (K-SADS-PL). Family psychiatric history and demographics were also evaluated. RESULTS Of the offspring studied, 71.4% had a lifetime diagnosis of at least one psychiatric disorder (28.6% with a mood disorder, 40% with a disruptive behavior disorder and 20% with an anxiety disorder). Pure mood disorders (11.4%) occurred less frequently than mood disorders comorbid with attention deficit hyperactivity disorder (17.1%). Psychopathology was commonly reported in second-degree relatives of the offspring of parents with bipolar disorder (71.4%). CONCLUSIONS Our results support previous findings of an increased risk for developing psychopathology, predominantly mood and disruptive disorders, in the offspring of bipolar individuals. Prospective studies with larger samples are needed to confirm and expand these results.

Abstract
OBJECTIVE Anxiety disorders are among the most common comorbid conditions in youth with bipolar disorder. We aimed to examine the prevalence and correlates of comorbid anxiety disorders among youth with bipolar disorder. METHOD As part of the Course and Outcome of Bipolar Youth study, 446 youth, ages 7 to 17 years, who met DSM-IV criteria for bipolar I disorder (n = 260) or bipolar II disorder (n = 32) or met operationalized criteria for bipolar disorder not otherwise specified (n = 154) were included. Subjects were evaluated for current and lifetime Axis I psychiatric disorders at intake using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Aged Children-Present and Lifetime version, and standardized instruments were used to assess functioning and family history. RESULTS Forty-four percent (n = 194) of the sample met DSM-IV criteria for at least 1 lifetime anxiety disorder, most commonly separation anxiety (24%) and generalized anxiety disorders (16%). Nearly 20% met criteria for 2 or more anxiety disorders. Overall, anxiety disorders predated the onset of bipolar disorder. Subjects with bipolar II disorder were more likely than subjects with bipolar I disorder or bipolar disorder not otherwise specified to have a comorbid anxiety disorder. After adjusting for confounding factors, youth with bipolar disorder with anxiety were more likely to have bipolar II disorder; longer duration of mood symptoms; more severe ratings of depression; and family history of depression, hopelessness, and somatic complaints during their worst lifetime depressive episode than those without anxiety. CONCLUSIONS Comorbid anxiety disorders are common in youth with bipolar disorder, and they most often predate bipolar disorder onset. Bipolar II disorder, a family history of depression, and more severe lifetime depressive episodes distinguish youth with bipolar disorder with comorbid anxiety disorders from those without. Careful consideration should be given to the assessment of comorbid anxiety in youth with bipolar disorder.

Abstract
Child and adolescent bipolar disorder (BPD) is a serious psychiatric disorder that often causes significant impairment in functioning. Pharmacological intervention is the cornerstone of treatment for bipolar youth, although psychotherapeutic interventions may be beneficial as adjunctive treatment. Medications used for the treatment of BPD in adults are still commonly used for bipolar children and adolescents. With the recent US FDA indication of risperidone, aripiprazole, quetiapine and olanzapine for the treatment of bipolar youth, the atypical antipsychotics are rapidly becoming a first-line treatment option. However, these agents are associated with adverse effects such as increased appetite, weight gain and type II diabetes mellitus. Although several evidence-based medications are now available for the treatment of BPD in younger populations, additional studies to evaluate the short- and long-term efficacy and potential for adverse events of these and other medications are needed.

Abstract
BACKGROUND Reported rates of bipolar syndromes are highly variable between studies because of age differences, differences in diagnostic criteria, or restriction of sampling to clinical contacts. METHOD In 1395 adolescents aged 14-17 years, DSM-IV (hypo)manic episodes (manic and hypomanic episodes combined), use of mental health care, and five ordinal subcategories representing the underlying continuous score of (hypo)manic symptoms ('mania symptom scale') were measured at baseline and approximately 1.5, 4 and 10 years later using the Munich-Composite International Diagnostic Interview (DIA-X/M-CIDI). RESULTS Incidence rates (IRs) of both (hypo)manic episodes and (hypo)manic symptoms (at least one DSM-IV core symptom) were far higher (714/105 person-years and 1720/10(5) person-years respectively) than traditional estimates. In addition, the risk of developing (hypo)manic episodes was very low after the age of 21 years [hazard ratio (HR) 0.031, 95% confidence interval (CI) 0.0050-0.19], independent of childhood disorders such as attention deficit hyperactivity disorder (ADHD). Most individuals with hypomanic and manic episodes were never in care (87% and 62% respectively) and not presenting co-morbid depressive episodes (69% and 60% respectively). The probability of mental health care increased linearly with the number of symptoms on the mania symptom scale. The incidence of the bipolar categories, in particular at the level of clinical morbidity, was strongly associated with previous childhood disorders and male sex. CONCLUSIONS This study showed, for the first time, that experiencing (hypo)manic symptoms is a common adolescent phenomenon that infrequently predicts mental health care use. The findings suggest that the onset of bipolar disorder can be elucidated by studying the pathway from non-pathological behavioural expression to dysfunction and need for care.

Abstract
BACKGROUND 22q11.2 Deletion Syndrome (22qDS) is a common chromosome deletion syndrome that has been associated with severe psychopathology, including bipolar disorder and schizophrenia, in adults. Assessment of psychiatric diagnoses in children and adolescents with 22qDS is in the early stages of investigation. METHODS 24 children and adolescents with 22qDS established by chromosomal analysis were randomly selected from a 22qDS clinic. Children and their parents were interviewed by trained psychometricians with a standardized structured diagnostic interview. A diagnosis was considered present if DSM-IV diagnostic criteria were met on either the parent or the child interview. RESULTS 24 22qDS subjects (mean age 9.7+/-3.3 years) had a mean of two DSM-IV psychiatric disorders. 79% met criteria for at least one DSM-IV psychiatric disorder and over one third had three or more diagnoses. 12.5% met criteria for major depression but none had bipolar disorder. Anxiety disorders (54%), attention-deficit/hyperactivity disorder (38%), and oppositional defiant disorder (38%) were common. Although 29% reported at least one psychotic-like symptom, none met criteria for a psychotic disorder. LIMITATIONS Small sample size may have obscured significant associations. Other limitations included non-blinded interviewers and lack of a simultaneously studied control group. CONCLUSION Affective, anxiety, attentional, and behavioral disorders were relatively common in this randomly selected group of children and adolescents with 22qDS. No child met criteria for bipolar disorder or schizophrenia. Prospective, longitudinal study is needed to determine whether early psychiatric symptomatology in children with 22qDS predicts continuing or more severe psychopathology later in life. Early psychiatric screening and monitoring appears warranted in 22qDS patients.

Abstract
Childhood parasomnias and movement disorders arise from a variety of etiologic factors. For some children, psychopathology plays a causal role in sleep disorders; in other cases, recurrent parasomnia episodes induce psychopathology. Current research reveals complex interconnections between sleep and mental health. As such, it is important that clinicians consider the impact psychiatric disorders have on childhood parasomnias. This article describes common parasomnias and movement disorders in children and adolescents, with emphasis on psychologic and behavioral comorbidities.

Abstract
Velocardiofacial syndrome, now known as 22q11.2 deletion syndrome (22qDS), is estimated to affect more than 700 children born in the United States each year. Some clinical studies have found increased rates of schizophrenia in adults with 22qDS. However, these studies have been limited by small sample size and possible ascertainment bias. The psychiatric disorders most commonly reported in children and adolescents with 22qDS have been attention-deficit/hyperactivity disorder, oppositional defiant disorder, anxiety disorders, and major depression. Psychotic symptoms have been observed in 14% to 28% of children with 22qDS, but their clinical significance remains uncertain. A 5-year follow-up study of 22qDS children who reported psychotic symptoms at baseline found they had an increased risk for a subsequent psychotic disorder. Thus, a broad differential diagnosis should be considered when 22qDS children present with psychotic symptoms. Longitudinal studies are needed to better understand the full extent of the psychopathology associated with 22qDS.

Prevalence of enuresis and its association with attention-deficit/hyperactivity disorder among U.S. children: results from a nationally representative study.

Abstract
OBJECTIVE There are no published nationally representative prevalence estimates of enuresis among children in the United States using standardized diagnostic criteria. This study sets out to describe the prevalence, demographic correlates, comorbidities, and service patterns for enuresis in a representative sample of U.S. children. METHOD The diagnosis of enuresis was derived from parent-reported data for "enuresis, nocturnal" collected using the computerized version of the Diagnostic Interview Schedule for Children (C-DISC 4.0) from a nationally representative sample of 8- to 11-year-old children (n = 1,136) who participated in the 2001-2004 National Health and Nutrition Examination Surveys. RESULTS The overall 12-month prevalence of enuresis was 4.45%. The prevalence in boys (6.21%) was significantly greater than that in girls (2.51%). Enuresis was more common at younger ages and among black youth. Attention-deficit/hyperactivity disorder (ADHD) was strongly associated with enuresis (odds ratio 2.88; 95% confidence interval 1.26-6.57). Only 36% of the enuretic children had received health services for enuresis. CONCLUSIONS Enuresis is a common condition among children in the United States. Few families seek treatment for enuresis despite the potential for adverse effects on emotional health. Child health care professionals should routinely screen for enuresis and its effects on the emotional health of the child and the family. Assessment of ADHD should routinely include evaluation for enuresis and vice versa. Research on the explanations for the association between enuresis and ADHD is indicated.

Comorbidity of adult attention-deficit hyperactivity disorder and bipolar disorder: prevalence and clinical correlates. Eur Arch Psychiatry Clin Neurosci 2008; 258:385-93.

Abstract
The aim of this study was to determine the frequency of adult attention deficit hyperactivity disorder (ADHD) comorbidity with lifetime bipolar disorder, and the influence of this comorbidity on various demographic and clinical variables in patients. Patients (n=159) with a previous diagnosis of bipolar disorder (79 female, 80 male) were included in this study. All patients were interviewed for the presence of current adult and childhood ADHD diagnosis and other axis I psychiatric disorder comorbidities using the structured clinical interview for DSM-IV (SCID) and the Schedule for Affective Disorders and Schizophrenia for School Age Children-Present and Lifetime Version (K-SADS-PL). The subjects also completed a Wender Utah rating scale (WURS-25) and a Current Symptoms Scale for ADHD symptoms. In particular, patients' clinical characteristics, the age of onset of bipolar disorder, and the number of episodes were noted. Twenty-six of the 159 bipolar patients (16.3%) were diagnosed with adult ADHD, while another subgroup of patients (n=17, 10.7%) received a diagnosis of childhood ADHD but did not fulfill criteria for adult ADHD. Both of these two subgroups (patients with adult ADHD, and patients with only childhood ADHD) had an earlier age of onset of the disease and a higher number of previous total affective or depressive episodes than those without any lifetime ADHD comorbidity. However only bipolar patients with adult ADHD comorbidity had higher lifetime comorbidity rates for axis I psychiatric disorders, such as panic disorder and alcohol abuse/dependence, compared to patients without lifetime ADHD. Bipolar patients with comorbid adult ADHD did not differ from bipolar patients with comorbid childhood ADHD in terms of any demographic or clinical variables except for adult ADHD scale scores. In conclusion, ADHD is a common comorbidity in bipolar patients, and it adversely affects the course of the disease and disrupts the social adjustment of the patients. Regular monitoring of ADHD will help to prevent problems and complications that could arise in the course of the disease, particularly in patients with early onset bipolar disorder.

Abstract
There is comparatively little information about premorbid maturational brain abnormalities in schizophrenia (SCZ). We investigated whether a history of childhood enuresis, a well-established marker of neurodevelopmental delay, is associated with SCZ and with measures of brain abnormalities also associated with SCZ. A Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) based history of enuresis, volumetric brain MRI scans and neuropsychological testing were obtained in patients with SCZ, their non-psychotic siblings (SIB) and non-psychiatric controls (NC). The subjects were 211 patients (79.6% male), 234 of their SIB (43.2% male) and 355 controls (39.2% male). Frequency of enuresis was compared across groups and correlated with cognitive measures. Total and regional brain volumes were determined using voxel-based morphometry on matched subsets of probands (n = 82) with or without enuresis (n = 16, n = 66, respectively) and controls (n = 102) with or without enuresis (n = 11, n = 91, respectively). Patients with SCZ had higher rates of childhood enuresis (21%) compared with SIB (11%; chi(2) = 6.42, P = 0.01) or controls (7%; chi(2) = 23.65, P < 0.0001) and relative risk for enuresis was increased in SIB (lambda(S) = 2.62). Patients with enuresis performed worse on two frontal lobe cognitive tests [Letter Fluency (t = 1.97, P = 0.05, df = 200) and Category Fluency (t = 2.15, P = 0.03, df = 200)] as compared with non-enuretic patients. Voxel-based morphometry analysis revealed grey matter volume reductions in several frontal regions (right BA 9, right BA 10 and bilateral BA 45) and right superior parietal cortex (BA 7) in patients with a history of enuresis as compared with non-enuretic patients (all t > 3.57, all P < 0.001). The high frequency of childhood enuresis associated with SCZ and abnormalities in prefrontal function and structure in patients with a childhood history of enuresis suggest that childhood enuresis may be a premorbid marker for neurodevelopmental abnormalities related to SCZ. These findings add to the evidence implicating prefrontal dysmaturation in this disorder, potentially related to genetic risk factors.

Abstract
Impulsivity and anxiety, common features of bipolar disorder (BD), are each associated with a number of negative outcomes in BD. The relationship between anxiety and impulsivity, however, has not been a focus of study in BD. In this paper, we present data regarding the association between anxiety and impulsivity as measured by the Barratt impulsiveness scale (BIS-11) in 114 outpatients with BD. Results revealed that patients with a comorbid anxiety disorder displayed significantly higher levels of impulsivity relative to patients without an anxiety disorder. Moreover, a broad range of anxiety-related symptom domains was associated with greater impulsivity. Exploratory analyses also revealed that baseline anxiety symptoms were associated with elevated impulsivity at 9-month follow-up, although these relationships were less robust after covariate adjustment. These data demonstrate that anxiety is positively associated with impulsivity in patients with BD. Further studies are needed to elucidate the implications of and reasons for this association.

Abstract
Anxiety disorders are relatively common in children and adolescents with bipolar disorder. Research to date indicates they may impact the onset, course, and treatment response of bipolar illness in children. Anxiety disorders often precede the onset of pediatric bipolar disorder. Family studies suggest first-degree relatives of bipolar patients are at increased risk for developing mood and anxiety disorders compared with relatives of individuals without mood disorders. Childhood adversity has been associated with higher rates of comorbid anxiety disorders and more severe illness course in bipolar patients. Preliminary study of the neurobiology of bipolar disorder with comorbid anxiety disorders suggests it may be neurophysiologically distinct from bipolar disorder without comorbid anxiety. Bipolar disorder with comorbid anxiety disorders has been associated with greater functional impairment and slower recovery. Prospective, longitudinal studies are needed to help us better understand the relationship between bipolar disorder and comorbid anxiety disorders so that opportunities for early intervention and effective treatment can be realized.
