Rapid-cycling bipolar disorder (RCBD) is a particularly severe progressive modality. It is a poorly individualized entity. The profile of patients with this clinical specification is poorly defined, and therapeutic remedies are poorly codified. The aim of our work was to make a descriptive assessment of the sociodemographic, clinical and therapeutic characteristics of patients with TBCR, and to compare them with those of other patients with bipolar disorder.We conducted a retrospective, descriptive and comparative cross-sectional study of hospitalized patients divided into two groups: patients with rapid cycling and those without rapid cycling (TBNCR).Identifying patients at risk of developing rapid cycles and preventing their onset requires knowledge of the associated characteristics, and the adoption of a bio-psycho-social approach aimed at optimizing treatment and socio-professional reintegration.
