Study Summary

The purpose of this study is to see whether memantine improves memory function in participants with bipolar disorder who have minimal symptoms. Secondary analyses will test the role of memantine in improving residual mood symptoms (depression and mania) in participants with bipolar disorder. We hypothesize that in participants with bipolar disorder who have minimal symptoms memantine will be effective in improving cognitive functions, as measured by the difference in neuropsychological test scores at the beginning and at the end of the trial.

Primary Outcome

The CVLT is used to measure verbal learning and episodic long-term memory. It assesses learning, short- and long-delayed recall and recognition for a list of 16 shopping items. Subjects are expected to remember a list of words. They are asked to repeat the words remembered 5 times (5 trials). Each of the words correctly remembered, in each trial, is marked as 1 point. The reported data represent the number of correct items for the Trial 1, Trial 5, Short Delay Free Recall, and Long Delay Free Re
