NEUROSCIENCE AND EMOTION GROUPS:
NEUROIMAGING LAB Bipolar Disorder
Bipolar Disorder affects up to 1.5% of the population, with illness relapse rates estimated at between 37%
and 44% per year, a total mortality elevated by 58% (predominantly from suicide
and cardiovascular disease), and syndromic recovery after one year post manic or
mixed episodes only at 48%. Whilst it is clear clinically that mood
dysregulation, or affective instability, is a key symptom of the disorder, and
despite findings from studies demonstrating attentional biases towards, and
emotion labeling deficits for, emotive stimuli in individuals with bipolar
disorder, the nature of the neural mechanism underlying the affective
instability remains poorly understood. Clarification of this mechanism will be
crucial for the future development of effective therapeutic interventions for
this common but poorly-treated disorder.
