Brief Summary

This study will explore the possible effectiveness of levetiracetam in patients with bipolar illness who have not responded adequately to standard treatments. Levetiracetam was recently approved to treat seizures. Other drugs in the same class as levetiracetam, including carbamazepine and valproate, are widely recognized as substitute medications for lithium or are used as an adjunct to it, and other anticonvulsants have also shown promise in improving bipolar symptoms. Patients with bipolar illness whose manic, depressed or unstable moods are not adequately controlled by their current treatment and who have not responded previously to two standard treatments (i.e., lithium, valproate, carbamazepine or neuroleptics) may be eligible for this study. Participants will take levetiracetam starting at 500 mg daily. If this dose is well tolerated, it will be increased to 500 mg twice a day. Every 3 days, doses may be increased until the target dose of 3000 mg/day is reached. Higher doses, not to exceed 4000 mg/day, may be tried in patients who do not respond fully to the lower doses. Patients and observers will use standard ratings to evaluate the patients' response to therapy during the 8-week study. If, after 8 weeks, the results appear promising, patients may continue treatment for an additional 6 months to evaluate longer-term effects.

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

• Patients meeting DSM -IV criteria for bipolar I, bipolar II, bipolar NOS, and schizoaffective illness-bipolar type will be eligible for study. They will be enrolled in approved Protocol #97-M-0039 and thus will not have H.I.V. and will have provided consent for all of the rating forms utilized in this study.
• Patients with inadequate response to two standard agents (i.e., lithium, valproate, carbamazepine, or neuroleptics) in the treatment of bipolar illness will be eligible for open adjunctive levetiracetam.
• If serum creatinine is above normal, a creatinine clearance will be preformed; this must be above 85 in order for a patient to be eligible for this study.

You may not qualify if:

• Women of child-bearing age who are not on an active method of birth control or who are likely to become pregnant will be excluded.
• Men or women with significant renal disease will also be excluded.
• For the depressed phase, patients will have an IDS score of 18 or greater, an LCM depression score of low moderate or greater, and a GCI-BP severity score of moderate or greater for more than 2 weeks, i.e., the DSM-IV durational criteria.
• For the hypomanic/manic phase, patients will have an YMRS score of 8 or greater, an LCM mania rating of mild or greater, and a CGI-BP severity score of moderately ill or greater for 7 days or more.
• Those in the cycling group would meet the severity criteria for depression and mania. They would have four or more mood "switches," and have an overall illness rating on the CGI-BP severity score of moderate or greater.
