Résumé
If there is an abundant literature on the impact of bipolar illness on the family and/or caregivers of patients, few studies have addressed its impact on marital relationship and couple functioning. Uncovering information relating specifically to this topic may be particularly relevant due to the unusually high divorce rate among individuals with bipolar disorder. We therefore conducted a systematic literature search to evaluate the existing data on bipolar disorder and marital issues, with a special focus on the help and support that can be provided by mental health professionals in this regard. We identified quantitative studies with pre-defined outcomes as well as qualitative investigations trying to understand the experiences of partners. A total of 27 articles were included in the review. The literature was found to capture the impact of bipolar disorder on partners as well as on the marital relationship itself or the children. Bipolar illness has a negative impact on the lives of partners including self-sacrifice, caregiver burden, emotional impact, and health problems. This negative impact can be aggravated by a lack of care and a lack of information from health personnel. The negative impact on the relationship includes volatility in the relationship, stigmatization, dissatisfaction with sexual life, and lower rates of childbearing. Negative impacts are likely to favor disease relapses for the patient. Children may also be negatively impacted. However, the illness may sometimes have positive impacts such as personal evolution, strengthening relationship, or new hope and perspectives. Based on these findings, the interventions of mental health professionals should be aimed at minimizing the negative impacts while favoring the positive ones.
