Drug

As this is a non-interventional study designed to collect data as part of routine clinical practice, the selection and dosage of medication, treatment period, and whether or not to change it are all based on the clinician's judgment.

Primary outcomes

  1. Treatment pattern

    Time frame: Baseline, 8weeks, 12weeks

    Frequency and percentage of the therapeutic class of bipolar disorder agents administered within 8 weeks prior to baseline will be presented based on the patients' demographic factors and clinical characteristics. Furthermore, frequency and percentage of the therapeutic class patterns of bipolar disorder agents administered after baseline will be presented

Secondary outcomes

  1. Change From Baseline in Young Mania Rating Scale (YMRS) Score at 8 Weeks and 12Weeks.

    Time frame: Baseline, 8weeks, 12weeks

    The YMRS scoring system ranges from 0 (no symptoms) to 4 or 8 (severe symptoms)

  2. Change From Baseline in Patient Health Questionnaire-9 (PHQ-9) Score at 8 Weeks and 12Weeks.

    Time frame: Baseline, 8weeks, 12weeks

    The PHQ-9 scoring system ranges from 0 to 27, with higher scores indicating more severe depression. Each item is scored on a scale from 0 to 3

  3. Change From Baseline in Clinical Global Impression Scale-Severity (CGI-S) Score at 8 Weeks and 12Weeks.

    Time frame: Baseline, 8weeks, 12weeks
