BACKGROUND Early recognition of the prodromal symptoms of bipolar disorder, combined with a patient action plan, may help to prevent relapses. Sleep disturbances are frequent warning signs of both mania and depression. This study used cross correlation analysis to characterize the relationship between mood, sleep and bedrest in longitudinal data. METHODS(More)
BACKGROUND Numerous studies have observed that offspring of bipolar parents manifest a broad spectrum of psychiatric disorders. We tested the hypothesis that in high risk offspring, bipolar disorder evolves in a predictable clinical sequence from non-specific (non-mood) to specific (mood) psychopathology. METHODS Offspring from well-characterized families(More)
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 -(More)
Genetic mapping studies in bipolar disorder (BD) have been hampered by the unclear boundaries of the phenotypic spectrum, and possibly, by the complexity of the underlying genetic mechanisms, and heterogeneity. Among the suggested approaches to circumvent these problems, a pharmacogenetic strategy has been increasingly proposed. Several studies have(More)
It has been 60 years since Cade first described patients who responded to antimanic lithium treatment. Two decades later, responders to lithium stabilization emerged in larger numbers. The responses of many severely ill bipolar patients to lithium were striking and called for an explanation. Remarkable reactions to a simple ion generated hope for an(More)
OBJECTIVE A growing body of data suggests that a significantly enhanced salivary cortisol response to waking may indicate an enduring tendency to abnormal cortisol regulation. Our objective was to apply the response test to a population already known to have long-term hypothalamo-pituitary-adrenocortical (HPA) axis dysregulation. We hypothesized that the(More)
Bipolar disorder (BD) is a common and highly heritable mental illness and genome-wide association studies (GWAS) have robustly identified the first common genetic variants involved in disease aetiology. The data also provide strong evidence for the presence of multiple additional risk loci, each contributing a relatively small effect to BD susceptibility.(More)
The mortality of patients suffering from affective disorders is much higher than that of the general population; this excess is due to both suicides and cardiovascular disease. During long-term lithium treatment, the overall mortality has not been found to differ significantly from that of the general population but the question remains whether this(More)
Genome scans of bipolar disorder (BPD) have not produced consistent evidence for linkage. The rank-based genome scan meta-analysis (GSMA) method was applied to 18 BPD genome scan data sets in an effort to identify regions with significant support for linkage in the combined data. The two primary analyses considered available linkage data for "very narrow"(More)
Returning to the original problem of 'correcting' the earlier findings, it appears that it is not a question of who is right and who is wrong. Kraepelin outlined, and Angst clearly specified, the basic characteristics of the clinical course of unipolar and bipolar affective disorders which unfolds in patients without other pre-existing psychiatric disorders(More)
