The study aims to evaluate:

  • the frequency of subsyndromal symptoms or disorders observed during interepisode phases in bipolar patients, particularly after a depressive episode in which these subsyndromal disorders are the most frequent
  • the functional impact of these disorders, factors or symptom thresholds associated with functional remission, and factors associated with symptomatic remission over a sufficient follow-up (12 months).

Primary Outcome Measures:
  • The prevalence of sub-syndromal symptoms after an acute depressive episode in Bipolar Disorder patients, as measured by scoring on YMRS and MADRS scales and MVAS-BP self-administered questionnaire. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    The 10 items of the MADRS are scored as 0, 2, 4 and 6 (0 = no depressive symptoms; 6 = severe depressive symptoms). Total scores, ranging from 0 to 60, will be calculated by adding the values for the 10 items. The YMRS scale is composed of 11 items, scored from 0 to 4 (0 = no manic symptoms; 4 = severe manic symptoms). Total scores will be calculated by adding the scores for the 11 items. MVAS-BP questionnaire is composed of 26 visual analogue scales, each item is scored from 0 (extreme depressive pole) to 100 (extreme manic pole). Absence of symptoms is at the middle of the scale (value 50).

Secondary Outcome Measures:
  • Impact of sub-syndromal symptoms on functioning of real-life French Bipolar Disorder patients as measured by scoring on Functioning Assessment Short Test (FAST) scale. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
    Functioning Assessment Short Test (FAST) is a brief instrument designed to assess the main functioning problems experienced by psychiatric patients. The 24 items of the FAST questionnaire are scored from 0 to 3 (a score of 0 indicates that the patient does not experience any difficulties, while a score of 3 indicates that the patient experiences major difficulties). Total scores will be calculated by adding the scores for each item. Functional remission will be evaluated on the FAST scale ; functional remission will be defined as a score < 11 on the FAST questionnaire.

  • Number and type of factors associated with a symptomatic and functioning remission after recovery from an acute depressive bipolar episode in real-life French population. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
  • Description of the management patterns (such as number and drug-class of treatments, number and type of resource used) associated with the presence and absence of sub-syndromal symptoms after an acute bipolar depressive episode. [ Time Frame: 12 months ] [ Designated as safety issue: No ]
