Completed · Phase 4 · Has a placebo group

Conditions studied: Bipolar Disorder

In brief

The purpose of this study is to examine whether the medication pramipexole (Mirapex) may be able to improve cognitive problems (i.e. difficulties with thinking, memory, and concentration) that may be associated with bipolar disorder.

Who can join

Age: 18 and older, up to 65. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Subjects between 18 and 65 years of age, who meet Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria for BPD I or II (by SCID) and confirmed in the diagnostic consensus conference will be included.
• Subjects must also meet criteria for euthymia described above.
• All subjects must be taking a standard mood stabilizer at a stable therapeutic dose (i.e. lithium, carbamazepine, valproate, lamotrigine).

You may not qualify if…

• Subjects with a history of central nervous system (CNS) trauma, neurological disorder, Attention Deficit Hyperactivity Disorder (ADHD), or learning disability will be excluded.
• Subjects with a DSM-IV diagnosis of current or recent substance abuse or dependence (in the previous 1 month) will be excluded.
• Moreover, subjects with rapid-cycling during the past year will be excluded (based on SCID).
• Any subject with an active, unstable medical problem that may interfere with cognition will be excluded based on the investigator's judgment.
• While medication status is an important consideration in any study of bipolar disorder, the exclusion of patients taking any medication is not practical, given the high prevalence of combination pharmacotherapy for bipolar disorder. To help control for medication effects on cognition, we plan to limit the types of medications allowed by excluding certain medications with a known impact on cognitive performance.
• Subjects taking clozapine will be excluded due to it's potential overlapping mechanisms of action with pramipexole.
• Subjects taking prescription or over-the counter medications may also be excluded if these medications have been shown to impact cognition (i.e. diphenhydramine).
• The use of benzodiazepines, sedatives, or sleeping pills, within 6 hours of neurocognitive testing will not be allowed. In addition, patients taking topiramate, tricyclic antidepressants, or anticholinergic medications that are known to impact cognition will be excluded from participation.
• Subjects taking any medications that are known to interact with pramipexole (i.e. Zantac, Tagamet, Reglan, Benemid, Probalan, Compazine, Phenergan, quinidine, selegiline, verapamil, and any other medication with a known interaction) will also be excluded.
