Prevalence, chronicity, burden and borders of bipolar disorder.

Bipolar disorder (BD) has traditionally been thought of as an episodic condition, characterized by periods of hypomania/mania and depression. However, evidence is accumulating to suggest that this condition is associated with significant chronicity. For a large proportion of patients with BD, residual, sub-syndromal symptoms persist between major syndromal episodes, and studies have shown that many patients with bipolar disorder are symptomatic for approximately 50% of the time over follow-up periods of greater than 10 years. Moreover, while the prevalence of BD has been estimated to be around 1-2%, there is growing evidence that this may be a substantial underestimation. There are a number of reasons for this potential underestimation, including difficulties in diagnosis. Adding to the burden of BD is the issue of comorbidity, with an increased prevalence of many chronic conditions in those with a primary diagnosis of BD. Conversely, for many patients with chronic conditions, both medical and psychiatric, BD frequently exists as a comorbid secondary diagnosis. This issue of comorbidity complicates estimates of use of pharmaceutical agents for BD, such as mood stabilizers, which are known to be used off-label in conditions such as borderline personality or substance use disorder. We speculate that such off-label prescribing may not be truly off-label but may be instead fully justified by an overlooked secondary diagnosis of BD. Finally, we discuss the association of bipolar disorder with a significant economic burden, to the individual and to society, both due to the direct costs of medical expenditure and indirect costs such as loss of productivity and increased mortality.

Romantic attachment in patients with mood and anxiety disorders.

INTRODUCTION: Romantic attachment is the establishment of a relationship with a partner and is strongly influenced by the individual's attachment style. While several studies have shown that attachment style may contribute to the development of psychopathology, less information is available for romantic attachment. The aim of the present study was to compare romantic attachment styles among patients with different mood and anxiety disorders and control subjects. METHOD: The study sample included a total of 126 outpatients, 62 of whom were affected by bipolar disorders, 22 by major depressive disorder (MDD), 27 by panic disorder, 15 by obsessive-compulsive disorder, and 126 healthy control subjects. Romantic attachment was assessed by means of the Italian version of the "Experiences in Close Relationships" (ECR) questionnaire. RESULTS: The results showed that the secure attachment style was more frequent in the control group, while the preoccupied style prevailed among the patients, with no difference among the diagnostic categories. The scores of the ECR anxiety and avoidance scales were significantly higher in the patients than in the control subjects. A trend toward higher ECR anxiety scale scores in women with panic disorder was detected, with the opposite being true for MDD. CONCLUSION: Our findings indicate that patients with different psychiatric disorders would be characterized by higher scores on both the ECR anxiety and the avoidance scales, as well as by the preoccupied style of attachment. In addition, women with panic disorder and MDD seem to be characterized by, respectively, higher and lower scores of the ECR anxiety scale than men.
