Methods This review is throwing light on sleep changes associating bipolar disorders (BDs) with special emphasis on the type II BD cases. Results Sleep disturbance in BD can be both a risk factor and a symptom of mood episodes. Conclusion Sleep disturbance could be a trait marker of BD, although longitudinal assessments are warranted to assess the potential causal relations and the long-term implications of sleep disturbance in BD.
