Measure
Citicoline
Participants will receive active medication throughout the study. Citicoline will be given beginning at two capsules (500 mg/day) with an increase to four capsules (1000 mg/day) at week 2, six capsules (1500 mg/day) at week 4, and eight capsules (2000 mg/day) at week 6. Doses will be decreased, based on clinician judgment, due to side effects. Citicoline: Citicoline is a psychostimulant/nootropic. It is an intermediate in the generation of phosphatidylcholine from choline. Cognitive Behavioral Therapy (CBT): Participants will receive manual-driven Cognitive Behavioral Therapy (CBT: two sessions each week for 4 weeks followed by weekly sessions, total 16 sessions) specifically designed for persons with bipolar 1 disorder and substance abuse, and provided by a therapist with experience in CBT.
Placebo
Participants will receive placebo identical in appearance to Citicoline throughout the study. Placebo will be given beginning at two capsules (500 mg/day) with an increase to four capsules (1000 mg/day) at week 2, six capsules (1500 mg/day) at week 4, and eight capsules (2000 mg/day) at week 6. Doses will be decreased, based on clinician judgment, due to side effects. Placebo: Inactive ingredient matching the active medication in appearance. Cognitive Behavioral Therapy (CBT): Participants will receive manual-driven Cognitive Behavioral Therapy (CBT: two sessions each week for 4 weeks followed by weekly sessions, total 16 sessions) specifically designed for persons with bipolar 1 disorder and substance abuse, and provided by a therapist with experience in CBT.

SECONDARY outcome

Timeframe: 12 Weeks

As part of HRSD, the patient is rated by a clinician on 17 items that measure depressive symptom severity. The total score is calculated by summing the responses across all items. Lower scores (closer to 0) indicate the absence of depressive symptoms, while higher scores indicate the presence of depressive symptoms. Eight items are scored on a 5-point scale, ranging from 0 = not present to 4 = severe. Nine are scored from 0-2 (0 = not present; 2 = severe). The scale range of scores is 0-52.

SECONDARY outcome

Timeframe: 12 weeks

The Young Mania Rating Scale (YMRS) is a clinician-rated scale that has 11 items and is based on the patient's subjective report of his or her clinical condition over the previous 48 hours. There are four items that are graded on a 0 to 8 scale (irritability, speech, thought content, and disruptive/aggressive behavior), while the remaining seven items are graded on a 0 to 4 scale. These four items are given twice the weight of the others to compensate for poor cooperation from severely ill patients. The total score is calculated by summing answers to all the item on the scale, with a higher score indicative of more severe mania symptoms. The scale total score ranges from 0 (absence of manic symptoms) to 60 (severe manic symptoms).
