Description
Inclusion Criteria:
- Aged 21 to 50 years.
- Diagnosed with Bipolar Disorder I or II disorder.
- Currently in the depressive phase of the illness.
- Montgomery Asberg Depression Rating Scale (MADRS) score greater than 15.
- Medication regimen (Lamotrigine, Valproate, Lithium, either alone or in combination with atypical antipsychotics, or typical antipsychotics) at stable doses for at least one month.
- Has an established residence and phone.
- Capable of providing informed consent.
Exclusion Criteria:
- Met Diagnostic and Statistical Manual 4th edition (DSM-IV-TR) criteria for rapid cycling within the 6 months prior to enrolling in the study.
- Meets DSM-IV-TR criteria for Schizophrenia, Schizoaffective disorder, Post-Traumatic Stress disorder, Obsessive-Compulsive disorder, or Eating disorder. Co-morbid anxiety disorders are not a reason for exclusion.
- History of psychotic symptoms at any point during the subject's illness.
- Met DSM-IV-TR criteria for alcohol or substance (except for nicotine) dependence or abuse within the past 6 months.
- Lifetime history of amphetamine abuse or dependence.
- Subject has a lifetime history of stimulant-induced mania
- History of seizures, including febrile seizures in childhood.
- Young Mania Rating Scale (YMRS) greater than 8.
- History of significant coronary artery disease, angina, untreated or inadequately treated thyroid disease (less than 1 month chemically euthyroid), type I diabetes, autoimmune disease, glaucoma, hypertension, seizures, or other medical condition(s) which in the opinion of the principal investigator is likely to significantly impact the subject's mood or potential response to the study medication.
- Electrocardiogram (ECG) with significant arrhythmias or conduction abnormalities, which in the opinion of the physician investigator preclude study participation; uncontrolled hypertension (>160/100) or tachycardia (heart rate >110).
- Female subjects who are peri or post-menopausal.
- Subjects taking Ritalin or other stimulants, theophylline, steroids, atomoxetine, cholinesterase inhibitors, memantine, modafinil, warfarin, anticonvulsants, clonidine, theophylline, monoamine oxidase inhibitors, and pseudoephedrine, or other medications that are likely to significantly interact (either pharmacokinetically or pharmacodynamically) with the subject's mood or Lisdexamfetamine.
- Subject regularly (more than 4 days per week) ingests more than four caffeine containing drinks per day.
- Pregnancy.
- In women of childbearing potential, an unwillingness to avoid pregnancy for the duration of the study.
- Active suicidal ideation.
- History of homicidal ideation.
- Allergy or other clinical condition which prohibits the use of all of the approved mood stabilizers or Lisdexamfetamine.
- Metal in the body (e.g. history of working as a sheet metal worker) or pacemaker which is a contra-indication to magnetic resonance imaging (MRI).
- Significant claustrophobia.

Measure Description |
Time Frame |
|---|---|---|
|
Change in Montgomery Asberg Depression Rating Scale (MADRS) Score Over Time.
Time Frame: baseline and 8 weeks
|
The change in MADRS score from the baseline visit to the week 8 visit is reported.
The MADRS is a clinician-rated scale that consists of 10 items rated on a from 0 to 6 (maximum score of 60), with higher scores indicating greater symptom severity.
An increase in score indicates a worsening of symptoms whereas a decrease indicates an improvement in symptoms.

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Change in Clinical Global Impressions Severity (CGI-S) Score.
Time Frame: baseline and week 8
|
The CGI-S score reflects the clinician's overall impression of the patient's functional status.
The scoring for the single item ranges from 1 with an anchor of "normal, not at all ill" to 7 with an anchor of "among the most extremely ill patients".
Thus, higher scores indicate greater severity of symptoms.
|
baseline and week 8
|
|
Change in Clinical Global Impressions Improvement (CGI-I) Score.
Time Frame: week 1 and week 9
|
The CGI-I score indicates the clinician's overall assessment of improvement in function from one visit to the next.
The single item is scored from 1 to 7 with anchor points ranging from very much improved (1) to very much worse (7).
A decrease in score reflects an improvement in functional status.
