Bipolar disorder is a severe psychiatric disease characterized by varying treatment response among individual patients. Effects of certain treatments, for instance, lithium, can be predicted from clinical characteristics of patients and their family histories. This led to a suggestion that a treatment response could identify subtypes of bipolar disorder particularly suited for gene-mapping studies. In this paper we review family and molecular studies of bipolar disorder responsive to lithium, as well as studies aiming to identify polymorphisms associated with the treatment response itself. While molecular genetic research and gene expression studies promise to bring new insights into the pathophysiology of the illness and the nature of treatment response, and thus provide new information for better treatment of bipolar disorder in the future, results from family studies and studies of clinical correlates of treatment response may already be utilized in the management of bipolar disorder.
The authors examined the relation of negative affect to mortality in the Religious Orders Study, a longitudinal cohort study of older persons, between 1994 and 2002. Participants were 851 Catholic clergy members without dementia at baseline (mean age, 75.4 (standard deviation, 6.9) years; 68% women). They completed standard measures of depressive symptoms, proneness to anxiety and anger, and patterns of anger expression at baseline and then underwent annual clinical evaluations for a mean of 4.7 (standard deviation, 2.7) years. The association of each scale with mortality was examined in proportional hazards models adjusted for age, sex, education, measures of cognitive function, lower limb function, chronic illness, smoking, alcohol, and obesity. During follow-up, 164 persons died. Measures of internally experienced negative affect, such as depressive symptoms and suppressed anger, were related to mortality, but measures of externally directed negative affect, such as the tendencies to be angry with others and to express anger overtly, were not. Persons with a high score (90th percentile) on a summary measure of internally experienced negative affect were nearly twice as likely to die as persons with a low score (10th percentile). The results suggest that negative affect in older persons, especially internally experienced distress, is associated with an increased mortality risk.
