Bipolar disorder is a common and often chronic and debilitating mental illness. The depressive phase of bipolar disorder contributes the largest portion of the disorder, and treatment resistant bipolar depression represents a significant public health problem. Recent research has suggested that bipolar depression is associated with elevated brain glutamate activity. We hypothesize that riluzole, a drug approved for ALS which inhibits glutamate activity, will lead to clinical improvement in patients with bipolar depression.

- Change in Hamilton Depression Rating Scale [ Time Frame: Change from baseline to week 6 ] [ Designated as safety issue: No ]The Hamilton Depression rating Scale is a clinician-rated scale that measures the severity of depression symptoms using 21 items. The best score is zero (reflecting no depression) and the worst score is 63 (reflecting severe depression).

Detailed Description:
We hypothesize that riluzole will lead to significant reduction in depressive symptoms as measured by the Hamilton Depression Rating Scale (HAM-D). Additionally, improvement in depressive symptoms will be associated with reduced glutamate levels in the anterior cingulate cortex, but not parieto-occipital cortex, both at day two and day 42.
