Arts B, Jabben N, Krabbendam L, van Os J. A 2‐year naturalistic study on cognitive functioning in bipolar disorder. Objective: Cognitive alterations in bipolar disorder may reflect genetic influence. However, to what degree mood, medication, thyroid function and other factors impact on longitudinal cognitive functioning remains unclear. Method: A group of patients with bipolar (spectrum) disorder (n = 76) underwent two monthly cognitive assessments over a 2‐year period in a prospective, repeated measures design. Regression models were used to investigate associations with predictors, corrected for multiple testing. Results: Patients with bipolar disorder performed worse than healthy controls (n = 61) on all cognitive domains tested. Effect sizes were small, with a maximum of −0.36 for sustained attention. However, cognitive performance varied substantially over the 2‐ year follow‐up, co‐varying with subjective cognitive complaints and impacting on functioning. Alterations in sustained attention and motor speed were the only impairments that were invariant over time. Predictors had very limited explanatory power on temporal variation in cognition. Use of second‐generation antipsychotics was associated with the largest negative effects on cognition, which were evident in the areas of motor speed and basic information processing (−0.35 < β < −0.5). Conclusion: Cognitive function in bipolar disorder varies significantly over time, largely independent of clinical factors. The temporal stability of sustained attention is the exception, suggesting it may represent a possible candidate intermediary phenotype. 相似文献

Individuals with schizophrenia and bipolar disorder show alterations in functional neural connectivity during rest. However, resting‐state network (RSN) disruptions have not been systematically compared between the two disorders. Further, the impact of RSN disruptions on social cognition, a key determinant of functional outcome, has not been studied. Forty‐eight individuals with schizophrenia, 46 with bipolar disorder, and 48 healthy controls completed resting‐state functional magnetic resonance imaging. An atlas‐based approach was used to examine functional connectivity within nine RSNs across the cortex. RSN connectivity was assessed via nonparametric permutation testing, and associations with performance on emotion perception, mentalizing, and emotion management tasks were examined. Group differences were observed in the medial and lateral visual networks and the sensorimotor network. Individuals with schizophrenia demonstrated reduced connectivity relative to healthy controls in all three networks. Individuals with bipolar disorder demonstrated reduced connectivity relative to controls in the medial visual network and connectivity within this network was significantly positively correlated with emotion management. In healthy controls, connectivity within the medial and lateral visual networks positively correlated with mentalizing. No significant correlations were found for either visual network in schizophrenia. Results highlight the role of altered early visual processing in social cognitive deficits in both schizophrenia and bipolar disorder. However, individuals with bipolar disorder appear to compensate for disrupted visual network connectivity on social cognitive tasks, whereas those with schizophrenia do not. The current study adds clarity on the neurophysiology underlying social cognitive deficits that result in impaired functioning in serious mental illness. 相似文献

Objectives: Epidemiological studies suggest that elders with bipolar disorder (BD) may be at increased risk for dementia compared to the general population. We sought to investigate whether older adults with BD would present with more cognitive dysfunction than expected for their age and education, and whether they would experience a more rapid cognitive decline over three-year prospective follow-up.
Methods: Thirty-three subjects age ≥ 50, mean (SD) age 69.7 (7.9) years, with BD I (n = 28) and II (n = 5) had neuropsychological examination at baseline and longitudinally over three years. All subjects were administered the Dementia Rating Scale (DRS) when euthymic. Thirty-six mentally healthy comparators ('controls'), equated on age and education, were selected from ongoing studies in our research center examining the longitudinal relationship between late-life mood disorders and cognitive function.
Results: Compared to mentally healthy comparators, subjects with BD performed significantly worse on the DRS at baseline [mean (SD) 135.2 (4.7); n = 33 versus 139.5 (3.3); n = 36], and over follow-up [131.9 (7.7); n = 14 versus 139.1 (3.4); n = 22]. There was a group-by-time interaction between the subjects with BD and the controls [group × time: F (1,64) = 5.07, p = 0.028].
Conclusions: In our study, older adults with BD had more cognitive dysfunction and more rapid cognitive decline than expected given their age and education. Cognitive dysfunction and accelerated cognitive decline may lead to decreased independence, with increased reliance on family and community supports, and potential placement in assisted-living facilities. 相似文献

This study examined the contribution of demographic, syndromal and longitudinal course variables to the long-term prognosis of 165 bipolar patients prospectively observed over 10 years as part of the National Institute of Mental Health Collaborative Study of Depression. Although most baseline clinical and demographic variables were not strong prognostic indicators, switching polarity within episodes was. Most episodes among the poor-prognosis patients were polyphasic, while most episodes among the comparison group with a better prognosis were monophasic. There was no evidence of shortening of cycle lengths over follow-up for either the poor-prognosis group or the entire sample. The relevance of these findings to the 'kindling' model is discussed. 相似文献

Gildengers AG, Mulsant BH, Al Jurdi RK, Beyer JL, Greenberg RL, Gyulai L, Moberg PJ, Sajatovic M, Ten Have T, Young RC, The GERI‐BD Study Group. The relationship of bipolar disorder lifetime duration and vascular burden to cognition in older adults.Bipolar Disord 2010: 12: 851–858. © 2010 The Authors. Journal compilation © 2010 John Wiley & Sons A/S. Objectives: We describe the cognitive function of older adults presenting with bipolar disorder (BD) and mania and examine whether longer lifetime duration of BD is associated with greater cognitive dysfunction. We also examine whether there are negative, synergistic effects between lifetime duration of BD and vascular disease burden on cognition. Methods: A total of 87 nondemented individuals with bipolar I disorder, age 60 years and older, experiencing manic, hypomanic, or mixed episodes, were assessed with the Dementia Rating Scale (DRS) and the Framingham Stroke Risk Profile (FSRP) as a measure of vascular disease burden. Results: Subjects had a mean (SD) age of 68.7 (7.1) years and 13.6 (3.1) years of education; 50.6% (n = 44) were females, 89.7% (n = 78) were white, and 10.3% (n = 9) were black. They presented with overall and domain‐specific cognitive impairment in memory, visuospatial ability, and executive function compared to age‐adjusted norms. Lifetime duration of BD was not related to DRS total score, any other subscale scores, or vascular disease burden. FSRP scores were related to the DRS memory subscale scores, but not total scores or any other domain scores. A negative interactive effect between lifetime duration of BD and FSRP was only observed with the DRS construction subscale. Conclusions: In this study, lifetime duration of BD had no significant relationship with overall cognitive function in older nondemented adults. Greater vascular disease burden was associated with worse memory function. There was no synergistic relationship between lifetime duration of BD and vascular disease burden on overall cognition function. Addressing vascular disease, especially early in the course of BD, may mitigate cognitive impairment in older age. 相似文献

Neurocysticercosis is the most common neuro-parasitosis caused by the larval stage of Taenia solium. The most common manifestations include seizures and hydrocephalus. Psychiatric abnormalities are relatively rare but depressive symptoms are frequent in patients with neurocysticercosis. However, mania as a presentation is relatively rare. Pregnancy and the postpartum period are relatively vulnerable times and they can lead to reactivation of existing neurocysterci lesions. We are discussing the case of a 23-year-old female patient with neurocysticercosis leading to the reactivation of lesions in the peripartum and postpartum period leading to bipolar affective disorder. Improvement in the patient was seen with a combination of antipsychotics, antihelmintics, antiepileptics and steroids, along with improved radiological signs of neurocysterci lesions. Although neurocysticercosis is a common illness, its prevalence presenting as a manic episode is merely 2.6% and, hence, missed easily. Therefore, it is important to rule out organic aetiology in patients even with a classic presentation of bipolar affective disorder and those having any other neurological symptoms and signs. 相似文献

Objective: We investigated gender differences in bipolar disorder (BD) type I and II in a representative cohort of secondary care psychiatric in‐ and out‐patients. Method: In the prospective, naturalistic Jorvi Bipolar Study of 191 secondary care psychiatric in‐ and out‐patients, 160 patients (85.1%) could be followed up for 18 months with a life chart. Results: After adjusting for confounders, no marked differences in illness‐related characteristics were found. However, female patients with BD had more lifetime comorbid eating disorders (P < 0.001, OR = 5.99, 95% CI 2.12–16.93) but less substance use disorders (P < 0.001, OR = 0.29, 95% CI 0.16–0.56) than males. Median time to recurrence after remission was 3.1 months longer among men than women, female gender carrying a higher hazard of recurrence (P = 0.006, HR = 2.00, 95% CI 1.22–3.27). Conclusion: Men and women with type I and II BD have fairly similar illness‐related clinical characteristics, but their profile of comorbid disorders may differ significantly, particularly regarding substance use and eating disorders. In medium‐term follow‐up, females appear to have a higher hazard of recurrence than males. 相似文献

Schouws SNTM, Stek ML, Comijs HC, Dols A, Beekman ATF. Cognitive decline in elderly bipolar disorder patients: a follow‐up study. Bipolar Disord 2012: 14: 749–755. © 2012 The Authors. Journal compilation © 2012 John Wiley & Sons A/S. Objective: Older individuals with bipolar disorder may exhibit greater cognitive decline over time compared to mentally healthy elderly individuals. We aimed to investigate neurocognitive performance in bipolar disorder over a period of two years. Methods: A comprehensive neuropsychological test battery was applied at baseline and two years later to 65 euthymic elderly outpatients with bipolar disorder (mean age = 68.35, range: 60–90 years) and to a demographically comparable sample of 42 healthy elderly controls. A general linear model was used to measure changes over time for the two groups. The impact of baseline illness characteristics on intra‐individual change in neurocognitive performance within the bipolar group was studied by using logistic regression analysis. Results: At baseline and at follow up, bipolar disorder patients performed worse on all neurocognitive measures compared to the healthy elderly group. However, there was no significant group‐by‐time interaction between the bipolar disorder patients and the comparison group. Conclusions: Although older bipolar disorder patients have worse cognitive function than normal controls, they did not have greater cognitive decline over a period of two years. 相似文献

Objectives: Neuropsychological studies in subjects with bipolar disorder (BD) have reported deficits on a variety of cognitive measures. However, because the majority of subjects were medicated at the time of testing in previous studies, it is currently unclear whether the pattern of deficits reported is related to BD itself or to psychotropic medication. We addressed this issue by examining cognitive performance in a group of unmedicated, currently depressed subjects with BD. Methods: Forty‐nine unmedicated subjects who met DSM‐IV criteria for BD, depressed phase, and 55 control subjects participated in this study. Most patients were diagnosed with bipolar II disorder. Performance on emotion‐dependent, or ‘hot’, and emotion‐independent, or ‘cold’, cognitive tasks was assessed using tests from the Cambridge Neuropsychological Test Automated Battery. Results: The groups were well matched with respect to general intelligence and demographic variables. Deficits in the unmedicated depressed BD group were apparent on tests tapping ‘hot’ cognitive processing, for example the Cambridge Gamble task and the Probabilistic Reversal Learning task. However, other than a deficit on the Spatial Span test in the depressed BD subjects, the groups performed equivalently on most measures of ‘cold’ cognitive processing, for example visual memory, attention, and working memory. Conclusions: These data suggest that deficits on tests involving reward processing, short‐term spatial memory storage, and sensitivity to negative feedback in depressed BD subjects represent an effect of the illness itself and not mood‐stabilizing medication. 相似文献
