OBJECTIVES: Changes in beliefs about the self are a central feature of bipolar disorder, with grandiose self-belief common in mania and low self-esteem evident in periods of depression. We investigated whether unstable self-esteem is a characteristic of bipolar disorder in remission. METHODS: We compared 18 patients with DSM-IV bipolar disorder in remission, 16 patients with unipolar disorder in remission, and 19 healthy controls. The primary measure was a diary kept for one week and completed twice each day, measuring self-esteem and positive and negative affect. We also administered Winters and Neale's (J Abnorm Psychol 1985; 94: 282-290) implicit measure of attributional style. RESULTS: Whereas mean levels of self-esteem and affect were not abnormal in the remitted bipolar patients, the bipolar patients showed strong fluctuations in these processes. In common with the unipolar patients, they also showed a pessimistic attributional style on the Pragmatic Inference Task (PIT). CONCLUSIONS: Instability of self-esteem and affect is present in bipolar patients, even when their symptoms are in remission, and has previously been found in people at genetic risk of the disorder. It may be a marker of vulnerability to the disorder. 相似文献

Comorbidity between bipolar disorder and anxiety disorders has attracted considerable attention in recent years. However,
a majority of the earlier studies examined anxiety disorders in acutely ill patients resulting in a possible confounding effect
of the affective episodes. This study examines the prevalence of anxiety disorders in remitted bipolar subjects recruited
from a psychiatric hospital in India and their effect on the severity of bipolar illness. A total of eighty remitted DSM-IV
adult bipolar subjects and 50 non-psychiatric controls were recruited over a 10-month period. They were evaluated using a
structured interview and various scales. The effect of anxiety disorders on bipolar severity was analyzed using multiple regression
analyses. Anxiety disorders were highly prevalent in bipolar subjects compared to controls (49 [61%] vs. 7 [14%], χ2 = 28.01, P < 0.001). Commonest lifetime anxiety disorder was obsessive-compulsive disorder (35%). Lifetime anxiety disorder had significant
effect on all four indices of severity of illness, that included (1) percentage of time spent in episodes (Beta = 18.67, SE
= 5.11, P < 0.001), (2) maximum period of continuous euthymia in the preceding 2 years (Beta = −5.26, SE = 1.71, P = 0.003), (3) presence of psychosis (Beta = 3.22, SE = 1.02, P = 0.002), and 4) response to mood stabilizers (Beta = −2.11, SE = 0.76, P = 0.006). The findings of this study confirm previous observations of the high prevalence and negative impact of comorbid
anxiety disorders in bipolar disorder and also demonstrate that the findings are similar in culturally diverse settings. Future
studies should systematically examine the various treatment options for anxiety disorders in bipolar patients. It is also
necessary to examine the neurobiological and family/genetic correlates of anxious bipolar subjects to validate if they are
a subgroup of bipolar disorders. 相似文献

OBJECTIVES: It is generally believed that cortisol secretion normalizes during clinical remission in mood disorders. However, this assumption has been challenged by preliminary reports of enhanced cortisol secretion in remitted bipolar patients and in the offspring of bipolar parents. The purpose of this study is to replicate findings of increased cortisol secretion during clinical remission in bipolar patients and in the offspring of bipolar parents, rigorously controlling for known confounders. METHODS: We conducted intensive cortisol sampling (six samples per day for three test days, on three consecutive weekends) on 15 bipolar type I and type II patients and 28 unrelated offspring of bipolar parents. Offspring had a history of unipolar depression. Participation was restricted to cases in complete sustained remission. Controls were matched as closely as possible for age, sex, and education. Mood and sleep measures were recorded on each sampling day. RESULTS: In total, 743 samples were collected from the patient group and 576 from controls. Correcting for repeat measures, there was no statistically significant difference in cortisol secretion at any sampling time between remitted bipolar patients, remitted offspring of bipolar parents, and normal controls. The cortisol waking response did not differ between patients and controls. Covariates, including sex, age, Beck depression score and hours of sleep, were not statistically significant. CONCLUSIONS: Our observations are consistent with the view that complete sustained clinical remission is associated with normal salivary cortisol levels throughout the day. A personal or family history of bipolar disorder per se does not appear to confer added risk for increased salivary cortisol secretion during sustained clinical remission. 相似文献

Nilsson KK, Jørgensen CR, Craig TKJ, Straarup KN, Licht RW. Self‐esteem in remitted bipolar disorder patients: a meta‐analysis. Bipolar Disord 2010: 12: 585–592. © 2010 The Authors.Journal compilation © 2010 John Wiley & Sons A/S. Objectives: Low self‐esteem has been found to be a risk factor for depression in major depressive disorder (MDD). In contrast, the role of self‐esteem in bipolar disorder (BD) is still uncertain. In order to examine the characteristics of self‐esteem in BD, we synthesized studies comparing self‐esteem in BD patients with self‐esteem in MDD patients and in normal controls. Methods: Database searches and identification of studies were conducted by two of the authors independently. Remission of BD and MDD was a major selection criterion. The results were generated through meta‐analyses. Results: Random‐effects models of 19 between‐group comparisons (N = 1,838) suggested that the self‐esteem of remitted BD patients was significantly lower than that of normal controls (Cohen’s d = ?0.83), while significantly higher than that of remitted MDD patients (Cohen’s d = 0.54). Fail‐safe numbers and tests for funnel plot asymmetry indicated that the results were robust and unlikely to reflect publication biases. Additional studies indicated that self‐esteem may take a fluctuating course during remission of BD. Conclusions: By revealing that BD patients do experience low self‐esteem, the findings implicate a need for further understanding the causes and therapeutic impact of such abnormality in BD. 相似文献

In mammals, corticotrophin-releasing hormone (CRH) and related peptides are known to play essential roles in the regulation of neuroendocrine, autonomic and behavioural responses to physical and emotional stress. In nonmammalian species, CRH-like peptides are hypothesized to play similar neuroendocrine and neurocrine roles. However, there is relatively little detailed information on the distribution of CRH neurones in the central nervous system (CNS) of nonmammalian vertebrates, and there are currently no comparative data on stress-induced changes in CRH neuronal physiology. We used a specific, affinity-purified antibody raised against synthetic Xenopus laevis CRH to map the distribution of CRH in the CNS of juvenile South African clawed frogs. We then analysed stress-induced changes in CRH immunoreactivity (CRH-ir) throughout the CNS. We found that CRH-positive cell bodies and fibres are widely distributed throughout the brain and rostral spinal cord of juvenile X. laevis. Strong CRH-immunoreactivity (ir) was found in cell bodies and fibres in the anterior preoptic area (POA, an area homologous to the mammalian paraventricular nucleus) and the external zone of the median eminence. Specific CRH-ir cell bodies and fibres were also identified in the septum, pallium and striatum in the telencephalon; the amygdala, bed nucleus of the stria terminalis and various hypothalamic and thalamic nuclei in the diencephalon; the tectum, torus semicircularis and tegmental nuclei of the mesencephalon; the cerebellum and locus coeruleus in the rhombencephalon; and the ventral horn of the rostral spinal cord. To determine if exposure to an acute physical stressor alters CRH neuronal physiology, we exposed juvenile frogs to shaking/handling and conducted morphometric analysis. Plasma corticosterone was significantly elevated by 30 min after exposure to the stressor and continued to increase up to 6 h. Morphometric analysis of CRH-ir after 4 h of stress showed a significant increase in CRH-ir in parvocellular neurones of the anterior preoptic area, the medial amygdala and the bed nucleus of the stria terminalis, but not in other brain regions. The stress-induced increase in CRH-ir in the POA was associated with increased Fos-like immunoreactivity (Fos-LI), and confocal microscopy showed that CRH-ir colocalized with Fos-LI in a subset of Fos-LI-positive neurones. Our results support the view that the basic pattern of CNS CRH expression arose early in vertebrate evolution and lend further support to earlier studies suggesting that amphibians may be a transitional species for descending CRH-ergic pathways. Furthermore, CRH neurones in the frog brain exhibit changes in response to a physical stressor that parallel those seen in mammals, and thus are likely to play an active role in mediating neuroendocrine, behavioural and autonomic stress responses. 相似文献

BACKGROUND: Reports about alterations of hypothalamic-pituitary-adrenocortical (HPA) function in patients with chronic posttraumatic stress disorder (PTSD) are inconsistent and controversial. More refined laboratory tests and subgrouping of PTSD patients might help to decrease variance of findings. METHODS: 14 subjects with chronic PTSD and 14 healthy controls were examined between 13:00 and 17:00 using a modified combined dexamethasone/CRH test (0.5 mg dexamethasone at 23:00, 100 microg CRH at 15:00). Plasma adenocorticotropic hormone (ACTH), cortisol and blood pressure were measured every 15 min from 14:45 until 17:00. RESULTS: No significant differences between patients and controls were found in the analyses of ACTH and cortisol levels, but a significantly elevated systolic and diastolic blood pressure in PTSD. Severity of depressive symptoms had no influence. However, explorative analyses showed that patients with a history of childhood traumatization had significantly higher post-dexamethasone-ACTH levels and a significantly lower diastolic blood pressure in comparison to patients without early trauma. CONCLUSIONS: In this first pilot study in a typical clinical sample of patients with chronic PTSD we found effects of severe adverse events in childhood on HPA axis regulation. Maybe, childhood traumatization could influence HPA axis findings in PTSD. Further research is needed, especially dose-response studies with different doses of dexamethasone in dexamethasone/CRH tests in PTSD. 相似文献

Stressful events before or just after parturition alter the subsequent phenotypical response to stress in a general process termed programming. Hypoxia during the period before and during parturition, and in the postnatal period, is one of the most common causes of perinatal distress, morbidity, and mortality. We have found that perinatal hypoxia (prenatal day 19 to postnatal day 14) augmented the corticosterone response to stress and increased basal corticotrophin-releasing hormone (CRH) mRNA levels in the parvocellular portion of the paraventricular nucleus (PVN) in 6-month-old rats. There was no effect on the levels of hypothalamic parvocellular PVN vasopressin mRNA, anterior pituitary pro-opiomelanocortin or CRH receptor-1 mRNA, or hippocampus glucocorticoid receptor mRNA. We conclude that hypoxia spanning the period just before and for several weeks after parturition programmes the hypothalamic-pituitary-adrenal axis to hyper-respond to acute stress in adulthood, probably as a result of drive from the parvocellular CRH neurones. 相似文献

Persistent attentional dysfunction in remitted bipolar disorder 总被引:1,自引:0,他引:1

Objectives: Although previous research has shown that attentional dysfunction is common during acute mood episodes in individuals with bipolar disorder (BPD), few studies have examined whether attentional deficits are evident during periods of symptom stability. The goal of this study was to determine whether clinically stable individuals with BPD would have attentional disturbances relative to healthy subjects. Methods: Fourteen patients with BPD and 12 healthy comparison subjects participated in the study, and were administered the Degraded Stimulus Continuous Performance Test (DSCPT), Digit Span Distractibility Test (DSDT) and Grooved Pegboard Test (GPT). Psychiatric symptoms were assessed with the Young Mania Rating Scale and the Scale for the Assessment of Positive Symptoms. Medication side effects were measured with the Simpson Rating Scale. Results: The patient group responded significantly more slowly than the control group on the DSCPT (z=−2.52, p=0.01) and the GPT (z=−3.37, p=0.001). There was a trend towards the BPD patients demonstrating impaired perceptual sensitivity on the DSCPT (z=1.68, p=0.09). The two groups did not differ on the DSDT (z=−1.06, p=0.3). Poor performance on the GPT and DSCPT target reaction time were not associated with symptom ratings or medications. Conclusion: The findings suggest that impairments in fine motor skills and reaction time may be present in clinically stable patients with BPD, even after accounting for psychiatric symptoms and medication effects. Performance decrements on attentional tasks may be in part reflective of motor impairments in patients with BPD. 相似文献

Objective: There is growing evidence of cognitive impairment as a trait factor in bipolar disorder. The generalizability of this finding is limited because previous studies have either focussed exclusively on bipolar I disorder or have analysed mixed patient groups. Thus, it is still largely unknown whether bipolar II patients perform differently from bipolar I patients on measures of cognitive functioning. Methodology: A total of 65 patients with bipolar I disorder, 38 with bipolar II disorder, and 62 healthy controls participated in the study. Patients had to be euthymic for at least one month. Clinical and demographic variables were collected in a clinical interview and with the Structured Clinical Interview for DSM‐IV. Cognitive functioning was assessed using a neuropsychological battery. Univariate and multivariate analyses of variance were conducted for analyzing possible differences between the groups. Results: The multivariate analysis of covariance (MANCOVA) indicated overall differences in neuropsychological performance between the three groups (Pillai Spur: F 1.96, p = 0.003). Post hoc comparisons revealed that patients with bipolar I disorder showed significantly lower scores in psychomotor speed, working memory, verbal learning, delayed memory, and executive functions than healthy controls. Patients with bipolar II disorder showed significant deficits in psychomotor speed, working memory, visual/constructional abilities, and executive functions compared to controls, but not on verbal learning and delayed memory. The two patient groups did not differ significantly from each other on any domain tested. Conclusion: These results support a similar pattern of cognitive deficits in both subtypes of bipolar disorder. 相似文献

It is well documented that oestrogen suppresses food intake by an action at the hypothalamic level. Using in situ hybridisation, we studied the effect of castration (CX) and short-term administration of oestradiol (E2) in CX female mice for three neuropeptides involved in feeding behaviour: two anorexigenic peptides, (i) the pro-opiomelanocortin (POMC)-derived peptide alpha-melanocyte-stimulating hormone and (ii) corticotrophin-releasing hormone (CRH), and the orexigenic peptide, (iii) neuropeptide Y (NPY). POMC-expressing neurones were mostly laterally located in the arcuate nucleus. POMC mRNA expression was decreased following CX and a single injection of E2 induced an increase in mRNA levels at 12- and 24-h time intervals. In the parvocellular area of the paraventricular nucleus, CRH mRNA levels were similarly decreased after CX and completely restored to normal levels at 12 and 24 h following E2 injection. On the other hand, the levels of NPY mRNA expressed in neurones located in the inner zone of the arcuate nucleus were increased by CX and decreased to the levels observed in intact animals by E2 injection (3-24 h). The present data suggest that oestrogen might exert an anorexigenic action by stimulating POMC and CRH mRNA expression and decreasing NPY mRNA expression in the hypothalamus. 相似文献

Objective: When dissimilar figures are presented to each eye individually, perception alternates spontaneously between each monocular view. This phenomenon, known as binocular rivalry, has been used as a powerful tool to investigate conscious visual awareness. Of clinical relevance, Pettigrew and Miller ( Proc Biol Sci 1998; 265: 2141-2148 ) found slow perceptual alternation rates in patients with bipolar I disorder (BD-I). For a better understanding of differences between BD-I and bipolar II disorder (BD-II), we examined whether perceptual alternation rates of binocular rivalry differ between the two subtypes of bipolar disorder.
Methods: The subjects comprised 25 healthy controls, 11 patients with BD-I, and 17 patients with BD-II. They underwent binocular rivalry examination. One-way analysis of variance was conducted to determine differences in the phase duration of binocular rivalry between the control, BD-I, and BD-II groups.
Results: Significant differences were observed in the mean phase duration of binocular rivalry between the groups. Although the medication administered did not differ significantly between the BD-I and BD-II patients, the phase duration was significantly longer among the BD-I patients than the BD-II patients and controls, whereas no significant difference was observed in the phase duration between the BD-II patients and controls.
Conclusion: The present results reveal a significant difference in the mean phase duration of binocular rivalry between subjects with BD-I and those with BD-II, suggesting the presence of some neurobiological difference between these two subtypes of bipolar disorder. 相似文献
