双相障碍基因遗传的最新研究和成果
     家族研究和双生子研究显示,双相障碍(BPD)是高度家族性显性遗传疾病。在过去20年中,作者花了很大精力来定位双相障碍的易感基因,但至今仍没有定论任何一个基因;不过,从相关研究得出的证据以及基因研究方法的改进使得基因辨认的前景重新变得一片光明...

神经胶质细胞功能障碍在双相障碍的病理生理中的作用
     一般认为,前额叶皮质(PFC)被认为是情绪的中枢,这个区域的异常经常可以导致抑郁和躁狂。回顾情感障碍患者的尸检研究结果,显示PFC胶质细胞数量和密度都有减少;同时在中间、眼窝、背外侧的PFC和扁桃体区等也有胶质细胞数量和密度的减少...

抑制PKC是否是治疗双相障碍的关键?
     第二信使的几个步骤,如增加Ca2+的释放、过度激活蛋白激酶的肌醇通路等,不仅仅意味着细胞代谢的过度旺盛,同时也与行为上的躁狂相对应。最近,这两者之间的关系有2个研究方向:1)Ca2+拮抗剂,例如尼莫地平,2)PKC抑制剂,例如他莫西芬,均被试用在躁狂发作...
双相障碍的认知、神经可塑性及其治疗
     认知功能受损和相应的神经生化改变在双相障碍的病理生理学方面起着重要的作用。但该事实很多年以来一直被人们所忽视,因为相对于精神分裂症而言大家都认为双相障碍是一种“预后良好”的疾病。但最近的研究显示,双相障碍在发作期间患者会表现出一定的、细微的、但与临床...

Many factors underpin bipolar disorder-obesity link(许多因素表明双相障碍与肥胖有关)
一项美国的研究结果指出,虽然肥胖在双相患者中较为普遍,但是其潜在的因素复杂多变,且个体之间差异很大。近来,关于肥胖与双相障碍联系的研究是个热门。但是,作者文中写道,双相障碍患者肥胖的起病与维持的机理是很难理解的。为了建立一个模型能够解释在这些患者...

Valproic acid, valproate and divalproex in the maintenance treatment of bipolar disorder
Background Although lithium has been the most commonly used maintenance treatment in bipolar disorder for several decades, valproate is being used increasingly - especially in the United States of America. There is a need to clarify whether the increasingly prominent pr...

A Review of Brief Medication-Adherence Instruments Used in Patients with Schizophrenia and Bipolar Disorder
Medication nonadherence is common,and patients suffering from psychiatric disorders are the least likely to adhere to pharmacotherapy as compared to patients who are receiving medication for physical symptoms associated with nonpsychiatric disorders.Nonadherence is espe...

Temporal lobe and “default” hemodynamic brain modes discriminate between schizophrenia and bipolar disorder
Schizophrenia and bipolar disorder are currently diagnosed on the basis of psychiatric symptoms and longitudinal course. The determination of a reliable, biologically-based diagnostic indicator of these diseases (a biomarker) could provide the groundwork for developing ...

Suicide Risk in Bipolar Disorder During Treatment With Lithium and Divalproex
CONTEXT: Several studies have suggested that lithium treatment reduces risk of suicide in bipolar disorder, but no research has examined suicide risk during treatment with divalproex, the most commonly prescribed mood-stabilizing drug in the United States. OBJECTIVE: To...

Cognitive function in childhood and early adulthood and hospital admission for schizophrenia and bipolar disorders in Danish men born in 1953
Objective This study examines the influence of cognitive function and change in cognitive function during adolescence on schizophrenia and bipolar disorders in adulthood and explores possible mechanisms for any associations. Method A cohort of 6923 men born in Copenhage...

Suggestive Linkage to Chromosomal Regions 13q31 and 22q12 in Families With Psychotic Bipolar Disorder
OBJECTIVE: Linkage studies of bipolar disorder and schizophrenia have found overlapping evidence for susceptibility genes in four chromosomal regions-10p12-14, 13q32, 18p11.2, and 22q12-13. The authors previously demonstrated familial clustering of psychotic symptoms-de...

Familiality of Polarity at Illness Onset in Bipolar Affective Disorder
OBJECTIVE: Bipolar affective disorder is clinically heterogeneous, and clinical features that run in families may help define more homogeneous phenotypes. The authors sought to establish whether polarity at illness onset, which is related to severity and course, is a fa...

Immune variations in bipolar disorder: phasic differences
Objectives To characterize the immunological variations of patients with a bipolar disorder (BD) diagnosis in manic (BDm) and depressive (BDd) phases, by the quantification of the serum levels of interleukin (IL)-1β, -2, -4, -6 and tumor necrosis factor alpha (TNF-α).Me...

Differences between prepubertal- versus adolescent- onset bipolar disorder in a Spanish clinical sample
Objective To examine patients attended and diagnosed with bipolar disorder (BD) at a child and adolescent psychiatry service; to record age of diagnosis and age of onset, and to study clinical differences between prepubertal and adolescent onset groups. Methods All pati...

Bipolar disorder and panic disorder in families an analysis of chromosome 18 data
OBJECTIVE: The authors performed an analysis of their published chromosome 18 linkage data on 28 families in which there was bipolar disorder to test the potential of comorbid panic disorder to define a genetic subtype of bipolar disorder. METHOD: Families ascertained t...
