This study suggests that cognitive vulnerability in patients with bipolar disorder is similar to that described in unipolar disorders. It is not clear whether this dysfunction is a cause or an effect of repeated episodes of bipolar disorder. However, the findings may have implications for clinical treatment as well as suggesting a number of important new avenues of research into psychological models of affective disorder.

These data confirm previous suggestions of elevated IL-1beta levels in major depression and postviral depression. IL-1beta is known to induce depressive symptoms as well as sickness behaviour and may contribute to the hypothalamic pituitary adrenal axis hyperactivity found in mood disorders.
