Decision-Making in Bipolar Disorder
Forty subjects with bipolar disorder who are not receiving a mood-stabilizing medication for the treatment of their illness will participate in this study. The study aims to evaluate how decision-making is affected by treatment for bipolar disorder. Prior to beginning treatment, patients will complete questionnaires and a one-hour computer-administered assessment of decision-making. Differences between pre-post decision-making outcomes will be evaluated to examine whether the neuroeconomic concepts of risk aversion, loss aversion, risk tolerance and delay discounting are affected by treatment.
The overall goal of this study will be to identify whether decision-making in people with bipolar disorder is affected by treatment. Specifically the investigators will compare decision-making characteristics among bipolar patients prior to treatment with how these decision-making characteristics change over the course of 6 weeks of standard medication therapy for bipolar disorder. A total of 6 decision-making tasks and one control task will be administered via computer to eligible subjects. The investigators will evaluate decision-making under varying conditions of reward, risk, and uncertainty and over time. The investigators hypothesize that decision-making will improve across these assessments after 6 weeks of treatment.

- Delay Equivalent [ Time Frame: 6 weeks ]Temporal discounting refers to the tendency to place less value on a reward as it moves away from the present time. Subjects will make decisions about whether to accept an immediate gain or loss verus a gain or loss occurring at some point in the future. Several iterations of choices are made using differing time frames. The results of these choices are then used to calculate the delay equivalent value.
