BACKGROUND: To examine the risk for psychopathology in offspring at risk for bipolar disorder and the course of psychiatric disorders in these youth. METHODS: Using structured diagnostic interviews (Structured Clinical Interview for DSM-IV [SCID] and Kiddie Schedule for Affective Disorders and Schizophrenia [K-SADS]), psychiatric diagnoses of 117 nonreferred offspring of parents with diagnosed bipolar disorder were compared with those of 171 age- and gender-matched offspring of parents without bipolar disorder or major depression. RESULTS: Compared with offspring of parents without mood disorders, high-risk youth had elevated rates of major depression and bipolar disorder, anxiety, and disruptive behavior disorders. High-risk offspring also had significantly more impaired Global Assessment of Functioning (GAF) scores, higher rates of psychiatric treatment, and higher rates of placement in special education classes. Disruptive behavior disorders, separation anxiety disorder, generalized anxiety disorder (GAD), social phobia, and depression tended to have their onset in early or middle childhood, whereas bipolar disorder, obsessive-compulsive disorder (OCD), panic disorder, and substance use disorder had onset most frequently in adolescence. CONCLUSIONS: These findings support the hypothesis that offspring of parents with bipolar disorder are at significantly increased risk for developing a wide range of severe psychiatric disorders and accompanying dysfunction. Early disruptive behavior and anxiety disorders, as well as early-onset depression, may be useful markers of risk for subsequent bipolar disorder in high-risk samples. 相似文献

OBJECTIVE: This study tested whether behavioral disinhibition is more prevalent among offspring of parents with bipolar disorder than among offspring of parents without bipolar disorder. METHOD: The authors conducted a secondary analysis of data from a preexisting high-risk study of offspring at risk for panic disorder and depression (N=278) that had included some children with parents who had bipolar disorder (N=34). Children (ages 2-6) had been classified as behaviorally inhibited, disinhibited, or neither in laboratory assessments. RESULTS: Offspring of bipolar parents had significantly higher rates of behavioral disinhibition than offspring of parents without bipolar disorder. Behavioral inhibition did not differ between groups. Differences were not accounted for by parental panic disorder or major depression or by parental history of attention deficit hyperactivity disorder, conduct disorder, antisocial personality, or substance use disorders. CONCLUSIONS: Results suggest a familial link between bipolar disorder in parents and behavioral disinhibition in their offspring. Behavioral disinhibition may be a familially transmitted predisposing factor for dysregulatory distress later in life. 相似文献

The hypothalamic-pituitary-adrenal (HPA) axis is compromised at several levels in major depressive and bipolar disorder (BD). However, it is not known whether HPA abnormalities predate the onset of these disorders. We conducted a pilot study comparing salivary cortisol levels of 10 adolescent offspring of parents with BD and 10 offspring of parents with no mental disorder (NMD). For two days, samples were collected at awakening and during the day in the adolescents' natural environment. The offspring of parents with BD had higher mean cortisol levels in the mornings and afternoons than the offspring of parents with NMD. When controlling for age, group differences in cortisol persisted in the afternoon, but not morning samples. None of the adolescents met diagnostic criteria for anxiety, affective, attention-deficit, or conduct disorders. Although preliminary, the results suggest that there is an early abnormality in the HPA system of the offspring of parents with BD. 相似文献

Thirty-nine children from intact families with a manic-depressive parent were evaluated by a semi-structured clinical interview and a number of rating scales for the presence or absence of psychopathology. This sample represents a larger one than in an earlier study, which showed minimal offspring psychopathology compared with reports of other investigators. The current study also examines the inter-relationships between the presence or absence of offspring psychopathology with both genetic loading and a number of psychosocial variables including measures of parental marital adjustment, severity and chronicity of proband parent illness and early exposure of children to parental illness. Nine of the thirty-nine children, (23%) received a positive DSM-III diagnosis, with depression of the dysthymic type being the most common. There was no significant correlation between genetic loading and offspring psychopathology. However, there were significant associations between children with psychopathology and paternal marital dissatisfaction and the age and chronicity of illness of the proband parent as compared with the children with no psychopathology. 相似文献

This study addressed the following question: are the adolescent and young adult offspring of parents with early-onset dysthymic disorder (DD) at increased risk for psychopathology? Participants included 41 offspring of 21 outpatients with early-onset DD, 19 offspring of nine outpatients with episodic major depressive disorder (MDD), and 32 offspring of 11 normal controls (NCs). Lifetime best-estimate diagnoses were determined for each offspring using a team consensus method. Diagnoses were derived blind to all information about the index parents. The offspring of outpatients with early-onset DD exhibited significantly higher lifetime rates of a broad range of psychiatric disorders than the offspring of NCs. In addition, the offspring of outpatients with early-onset DD exhibited significantly higher lifetime rates of DD, anxiety disorders, and phobia than the offspring of outpatients with episodic MDD. These results support the importance of early-onset DD in parents as a risk factor for psychopathology in their offspring. 相似文献

OBJECTIVE: A major aim of this longitudinal high-risk study is to identify reliable early indicators of emerging bipolar disorder (BD) among offspring from well-characterized parents. METHODS: High-risk offspring were recruited from families in which one parent had BD diagnosed on the basis of the Schedule for Affective Disorders and Schizophrenia - Lifetime version (SADS-L) interviews and DSM-IV diagnostic criteria and the other parent was well. Bipolar parents were further subdivided on the basis of response or non-response to long-term lithium. A comparison group of offspring was recruited from well parents diagnosed on the basis of either SADS-L interviews or the family history method. All consenting offspring from high-risk and control families were assessed longitudinally with the Schedule for Affective Disorders and Schizophrenia for School-aged Children - Present and Lifetime version (KSADS-PL) interviews and DSM-IV diagnoses were made on a blind consensus review. The offspring were reassessed on average annually, as well as at any time symptoms developed. RESULTS: Antecedent conditions to BD in both high-risk groups included sleep and anxiety disorders, while attention-deficit hyperactivity disorder and pre-psychotic conditions were antecedents among the offspring of lithium non-responders only. Among those offspring developing BD, the index mood episode was almost always depressive. CONCLUSIONS: Despite a specific genetic risk, BD began with non-specific psychopathology and/or depressive disorders in a majority of offspring. Therefore, diagnosis based only on cross-sectional assessment of symptoms appears to be insufficient for the accurate early detection of emerging BD. Other parameters such as family history and associated antecedents should be taken into account. 相似文献

OBJECTIVES: Disturbances in cognition, affect, sleep and activity have been identified in bipolar disorder (BD) but little is known about the possible role of these factors in the development of the condition. We studied these variables in a familial high-risk sample. METHODS: Twenty-five children (13-19 years) of bipolar parents were compared with 22 similar aged children of age- and sex-matched healthy controls. Participants were assessed using Schedule for Affective Disorders and Schizophrenia-Lifetime version (SADS-L) and completed self-report measures of dysfunctional attitudes, behavioural inhibition/activation, social rhythms, coping styles and subjective experience of sleep. Children completed a 7-day recording of actigraphy (sleep and activity) and a 7-day diary measuring self-esteem, positive and negative affect and reactions to positive and negative events. RESULTS: Fifty-six per cent of children of bipolar parents (CBP) reported mood symptoms compared to 9% of children of control parents (CC). The CBP group had coping styles and instability of self-esteem consistent with abnormal strategies for regulating affect. Both groups also differed on sleep measures. The majority of differences observed were between CBP with a current or past mood diagnosis and CC. BD parents reported dysfunctional coping styles and (to a lesser extent) disrupted activity patterns. CONCLUSIONS: A familial high-risk strategy for studying the role of psychological factors in BD is feasible and informative. This pilot study indicates that abnormal coping styles, instability of self-esteem and dysregulation of sleep may be early markers of bipolar illness. However, current findings need to be explored further in longitudinal studies to clarify which potential markers are truly predictive of BD. 相似文献

BACKGROUND: Cognitive dysfunction is evident in some euthymic patients with established bipolar disorder (BD), including deficits in visual backward masking (VBM) tasks which map to a specific neural pathway. A high-risk paradigm would clarify the temporal relation of cognitive dysfunction to clinical course. METHOD: We compared euthymic offspring (age range: 18-32 years) of lithium-responsive bipolar parents with and without a previous lifetime history of psychiatric illness to healthy comparison subjects with a negative family history, on a VBM task that requires target location. RESULTS: High-risk offspring with no lifetime psychiatric history performed the VBM task at levels of healthy controls. High-risk offspring with a previous history of a mood disorder, in complete remission, made significantly more errors at short target-mask intervals than control or never ill offspring. These higher error rates were not a consequence of faster response times. CONCLUSIONS: There is preliminary evidence of specific cognitive dysfunction early in the course of illness in affected offspring of parents with lithium responsive BD. VBM is ideal for future longitudinal studies addressing whether cognitive dysfunction in BD is a trait marker or a consequence of illness manifestation. 相似文献

Objective We sought to systematically review the literature on the psychiatric risk of offspring of parents with bipolar disorder (OPBD) using a developmental psychopathology framework. The review also sought to establish the utility of clinical stage modelling as a framework for identifying precursor disorders to later onset of bipolar disorder (BD) in OPBD. Methods A systematic search was performed using EMBASE, PsychINFO and Medline. Reference lists of included studies and previous reviews were also searched. Studies were included if they reported diagnostic outcomes for child, adolescent and young adult offspring of parents diagnosed with BD. Results Twenty‐six studies were identified representing 21 individual cohorts. The review identified that OBPD present as a high‐risk group for a range of mood and non‐mood disorders in childhood, adolescence and young adulthood. The trajectory of risk was from non‐mood disorders in childhood via non‐bipolar mood disorders in early adolescence towards mania/hypomania in late adolescence and early adulthood. From a clinical staging perspective, childhood anxiety disorders were associated with later onset of BD. Recurrent substance use disorder was identified as a risk in OPBD during late adolescence and early adulthood. Quality ratings indicated that studies were methodologically robust. Conclusions Our review provides evidence for a developmental psychopathology trajectory of precursor risks to BD in OPBD. There is support for clinical stage modelling as a conceptual framework for understanding developmental risk in OPBD and as a tool for developing early and individualized intervention strategies. 相似文献

Seven male children who each had a manic-depressive parent (five alos had a parent with unipolar depression) and 12 control children were studied. The proband children had shown a range of adjustment problems as infants and toddlers. Four years later, they continued to have substantial behavior problems, including ones that could be classified as DSM-III psychiatric diagnoses. On the basis of psychiatric interviews and psychological assessments, the proband children received more DSM-III diagnoses than the control children. Proband children reported internalizing symptoms; this pattern was corroborated by their mothers, who also characterized these children as showing antisocial behavior patterns. 相似文献

The hypothalamic-pituitary-adrenal (HPA) axis is compromised in major depression and bipolar disorder (BD). It is not known however whether HPA abnormalities predate the onset of these disorders. Preliminary data indicated that the adolescent offspring of parents with BD (high-risk), as compared to adolescents of parents with no mental disorder (low-risk), had higher levels of daytime salivary cortisol. The present study re-examined the cortisol increase after awakening and basal cortisol levels in a larger sample, and tested the hypothesis that high-risk offspring are more reactive to psychosocial stress than low-risk offspring. Saliva samples were collected from 58 adolescents, 29 high-risk (14 male/15 female, 16.8 years) and 29 (14 male/15 female, 16.6 years) low-risk, in their natural environment during at least two days. Twenty-five high-risk (13 male/12 female) and 25 low-risk (13 male/12 female) youth completed a child adaptation (15 years) or the standard version of the “Trier Social Stress Test”. Consistent with our previous finding, high-risk offspring had higher daytime levels of cortisol in their natural environment than low-risk offspring, and the difference was unrelated to clinical symptoms or other known confounds. Irrespective of risk status, female participants had higher daytime levels of cortisol than male participants. In contrast, there were no group differences in the cortisol response to the laboratory psychosocial stressor. The offspring of parents with BD show evidence of increased daytime basal HPA functioning with normal reactivity to psychosocial stress. 相似文献

Singh MK, Spielman D, Libby A, Adams E, Acquaye T, Howe M, Kelley R, Reiss A, Chang KD. Neurochemical deficits in the cerebellar vermis in child offspring of parents with bipolar disorder.Bipolar Disord 2011: 13: 189–197. © 2011 The Authors.Journal compilation © 2011 John Wiley & Sons A/S. Objectives: We aimed to compare concentrations of N‐acetyl aspartate, myo‐inositol, and other neurometabolites in the cerebellar vermis of offspring at risk for bipolar disorder (BD) and healthy controls to examine whether changes in these neuronal metabolite concentrations occur in at‐risk offspring prior to the onset of mania. Methods: A total of 22 children and adolescents aged 9–17 years with a familial risk for bipolar I or II disorder [at‐risk offspring with non‐bipolar I disorder mood symptoms (AR)], and 25 healthy controls (HC) were examined using proton magnetic resonance spectroscopy at 3T to study metabolite concentrations in an 8‐cc voxel in the cerebellar vermis. Results: Decreased myo‐inositol and choline concentrations in the vermis were seen in the AR group compared to HC (p < 0.01). Conclusions: Decreased cellular metabolism and interference with second messenger pathways may be present in the cerebellar vermis in youth at risk for BD as evident by decreased myo‐inositol and choline concentrations in this region. These results may be limited by a cross‐sectional design, co‐occurring diagnoses, and medication exposure. Longitudinal studies are necessary to determine whether early neurochemical changes can predict the development of mania. Improved methods for identifying children with certain neurochemical vulnerabilities may inform preventive and early intervention strategies prior to the onset of mania. 相似文献

Having one parent diagnosed with a severe mental disorder is considered one of the main risk factors for developing that disorder in adulthood, and it also increases the risk of a wide range of mental disorders in the offspring. The aim of this study is to compare the prevalence of several psychopathological diagnoses, the presence of prodromal symptoms, and global functioning in offspring of parents with schizophrenia or bipolar disorder and in offspring of controls at baseline and 2-year follow-up. This study included 41 offspring of parents with schizophrenia, 90 offspring of parents with bipolar disorder, and 107 offspring of controls (mean age 11.7 ± 3.2 at baseline and 13.9 ± 3.2 at follow-up). The prevalence of psychopathology and comorbidity was higher in offspring of parents with schizophrenia and offspring of parents with bipolar disorder than in offspring of controls at baseline and at 2-year follow-up. Interestingly, mood disorders were more prevalent in offspring of parents with bipolar disorder and disruptive disorders were more prevalent in offspring of parents with schizophrenia. Prodromal symptoms were more frequent in offspring of parents with schizophrenia than in offspring of controls, while the offspring of parents with bipolar disorder showed an intermediate pattern. Finally, global functioning was lower in the offspring of parents with schizophrenia than the offspring of parents with bipolar disorder and the offspring of controls. Screening patients’ children is clinically relevant, since, as a group, they have an elevated risk of developing a psychiatric disorder and of experiencing their first symptoms during childhood and adolescence. 相似文献

OBJECTIVE: To compare the prevalence of psychological disorders in parents of young children with and without attention-deficit/hyperactivity disorder (ADHD) and comorbid disruptive behavior disorders (DBD). METHOD: Subjects included 98 three- to seven-year-old children with DSM-IV ADHD (68 with ADHD and comorbid oppositional defiant or conduct disorder [ADHD+ODD/CD]) and 116 non-ADHD comparison children recruited in 1995-96 during the first wave of a longitudinal study. Biological mothers were administered interviews to assess ADHD and DBD in their children and mood, anxiety, and substance use disorders in themselves. In addition, they were queried about symptoms of childhood ADHD and DBD, and antisocial personality disorder in themselves and their children's biological fathers. RESULTS: Child ADHD was associated with increased rates of maternal and paternal childhood ADHD relative to comparison children. Child ADHD+ODD/CD was associated with maternal mood disorders, anxiety disorders, and stimulant/cocaine dependence, and paternal childhood DBD. Mothers of children with ADHD+ODD/CD also reported increased drinking problems in their children's fathers. CONCLUSIONS: These findings indicate that many young children with ADHD, particularly those with comorbid ODD/CD, require comprehensive services to address both their ADHD and the mental health needs of their parents. 相似文献
