Cyclothymic temperament possesses a central dimension that includes rapid fluctuations in mood and emotional instability, and it is regarded as a prodromal state of bipolar disorder. The aim of the present study is to explore the neural correlates of cyclothymic temperament. We used the data of 55 healthy participants in our previous study and analyzed the association between cyclothymic temperament scores rated by the Temperament Evaluation of Memphis, Pisa, Paris and San Diego-Autoquestionnaire (TEMPS-A) and the uptake of [(18)F]-FDG measured by positron emission tomography (PET)...

A single-nucleotide polymorphism substitution from glutamine (Gln, Q) to arginine (Arg, R) at codon 460 of the purinergic P2X7 receptor (P2X7R) has repeatedly been associated with mood disorders. The P2X7R-Gln460Arg variant per se is not compromised in its function. However, heterologous expression of P2X7R-Gln460Arg together with wild-type P2X7R has recently been demonstrated to impair receptor function. Here we show that this also applies to humanized mice co-expressing both human P2X7R variants. Primary hippocampal cells derived from heterozygous mice showed an attenuated calcium uptake upon agonist stimulation...

BACKGROUND: In clinical practice, some patients diagnosed with anxiety disorder (AD) may develop bipolar disorder (BD) many years later, and some cases of AD may be cured by the use of mood stabilizers. However, the relationship between AD and BD should be explored further. METHOD: To track how many cases of AD turned to BD and to discover the differences between them, we recruited 48 patients diagnosed with BD, who were assigned to the BD group for the retrospective analysis, and we also recruited 186 patients diagnosed with AD at enrolment; this latter group was asked to complete follow-up surveys conducted 3 months, 6 months, 12 months and 18 months after the primary stage of the study...

The current card sort exercise described by Agius et al. in 2006 provides a tool for patients and their families to characterise the temporal pattern of occurrence of both stereotyped and idiosyncratic prodromal symptoms that serve as early warning signs predicting a relapse. This 'individual relapse signature' is highly specific for bipolar relapse, and aids identification of a relapse such that patients can be channeled into appropriate early intervention pathways. This review examines the role of the card sort exercise in the treatment of bipolar disorder, and evaluates the evidence for its efficacy...

Illness staging is widely utilized in several medical disciplines to help predict course or prognosis, and optimize treatment. Staging models in psychiatry in general, and bipolar disorder in particular, depend on the premise that psychopathology moves along a predictable path: an at-risk or latency stage, a prodrome progressing to a first clinical threshold episode, and one or more recurrences with the potential to revert or progress to late or end-stage manifestations. The utility and validity of a staging model for bipolar disorder depend on its linking to clinical outcome, treatment response and neurobiological measures...

BACKGROUND: Affective and emotional symptoms such as depression, anxiety, euphoria, and irritability are common neuropsychiatric symptoms (NPS) in pre-dementia and cognitively normal older adults. They comprise a domain of Mild Behavioral Impairment (MBI), which describes their emergence in later life as an at-risk state for cognitive decline and dementia, and as a potential manifestation of prodromal dementia. This selective scoping review explores the epidemiology and neurobiological links between affective and emotional symptoms, and incident cognitive decline, focusing on recent literature in this expanding field of research...

AIM: Early intervention in bipolar disorder (BD) has received increasing attention in recent years. The identification of risk factors has improved, but researchers continue to struggle to find an effective treatment once the illness has become established. The aetiology of BD and feasibility of early intervention present a challenge, making it difficult to decide who to target, as well as how. METHODS: This essay seeks to address the lack of guidance for managing patients with a possible emerging bipolar illness, by presenting a rough roadmap to psychological care...

AIMS: Despite the considerable public health impact of bipolar disorder (BD), no psychosocial interventions have been systematically evaluated in its early prodromal stages. We describe the rationale, design and analytic methods for a 3-site randomized trial of family-focused treatment for youth at high risk (FFT-HR) for BD. METHODS: Participants (ages 9-17 years) have a diagnosis of unspecified BD or major depressive disorder, current mood symptoms and at least one first- or second-degree relative with a lifetime history of BD I or II...

Importance: Early identification of individuals at high risk for the onset of bipolar spectrum disorder (BPSD) is key from both a clinical and research perspective. While previous work has identified the presence of a bipolar prodrome, the predictive implications for the individual have not been assessed, to date. Objective: To build a risk calculator to predict the 5-year onset of BPSD in youth at familial risk for BPSD. Design, Setting, and Participants: The Pittsburgh Bipolar Offspring Study is an ongoing community-based longitudinal cohort investigation of offspring of parents with bipolar I or II (and community controls), recruited between November 2001 and July 2007, with a median follow-up period of more than 9 years...

BACKGROUND: Premorbid characteristics may help predict the highly variable functional and illness outcomes of young people with early stage Bipolar Disorder (BD). We sought to examine the relationships between premorbid adjustment and short to medium-term outcomes after a first treated episode of mania. METHODS: We examined the baseline and 18-month follow-up characteristics of 117 participants with first episode of mania, treated at two tertiary early intervention services in Melbourne, Australia...

OBJECTIVES: Early psychopathology in children diagnosed with Bipolar Disorder (BD) remains poorly characterized. Parental retrospective reports provide helpful details on the earliest manifestations and their evolution over time. These symptoms occur early in the course of BD, often before a formal diagnosis is made and/or treatment is implemented, and are of great importance to early recognition and prevention. METHODS: Parents of pre-pubertal children and adolescents with DSM-IV diagnoses of BD attending an outpatient mood disorders clinic provided retrospective ratings of 37 symptoms of child psychopathology...

BACKGROUND: Although the estimated contribution of genetic factors is high in bipolar disorder, environmental factors may also play a role. This Swedish register-based cohort study of men examined if physical and psychological characteristics in late adolescence, including factors previously linked with bipolar disorder (body mass index, asthma and allergy), are associated with subsequent bipolar disorder in adulthood. Unipolar depression and anxiety are analysed as additional outcomes to identify bipolar disorder-specific associations...

Alaina L Edmunds
Schizophrenia is the most common psychotic illness, typically appearing between the late teenage years and the mid-30s. The first episode of psychosis may be preceded by a prodromal period. Schizophrenia symptoms fall into six common symptom clusters: delusions and hallucinations, disorganization of speech, cognitive dysfunction, negative symptoms, affective symptoms, and motor system abnormalities. The diagnosis is based on criteria in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, including exclusion of other possible medical or psychiatric etiologies of psychosis...

PURPOSE: Studies focusing on the offspring of affected parents utilize the well-established familial aggregation of mood disorders as a powerful tool for the identification of risk factors, early clinical manifestations, and prodromes of mood disorders in these offspring. The major goals of the Lausanne-Geneva mood cohort study are to: (1) assess the familial aggregation of bipolar and unipolar mood disorders; (2) prospectively identify risk factors for mood disorders as well as their early signs and prodromes; (3) identify their endophenotypes including cognitive features, alterations in brain structure, HPA-axis dysregulation, and abnormalities of the circadian rhythm of activity...

BACKGROUND: Up to 60% of patients with bipolar disorder (BD) have a history of traumatic events, which is associated with greater episode severity, higher risk of comorbidity and higher relapse rates. Trauma-focused treatment strategies for BD are thus necessary but studies are currently scarce. The aim of this study is to examine whether Eye Movement Desensitization and Reprocessing (EMDR) therapy focusing on adherence, insight, de-idealisation of manic symptoms, prodromal symptoms and mood stabilization can reduce episode severity and relapse rates and increase cognitive performance and functioning in patients with BD...

INTRODUCTION: Both children affected by nutritional and eating disorders (ED) and adults with bipolar disorder (BD) display symptoms of deficient emotional self-regulation, which can present in different forms. If we observe the clinical and developmental histories of individuals affected by EDs and BD, based on a cognitive systemic post-rationalist approach, we can hypothesise a continuum between the two disorders. The aim of this pilot study is to support the hypothesis - from an explanatory rather than a non-descriptive approach - that EDs and BD are the possible result of issues tied to biological and psychological self-regulation...
