A new approach for seasonal pattern: is it related to bipolarity dimension? Findings from an Italian multicenter study.

CONCLUSIONS: A large number of patients with BD and seasonal pattern, but also a considerable number of patients with MDD and seasonal pattern, endorsed manic items during a current MDE. Seasonal pattern should be associated with a concept of bipolarity in mood disorders and not only related to bipolar disorder. A correct identification of seasonal patterns may lead to the implementation of personalised pharmacological treatment approaches. KEY POINTS High prevalence of mixed features in mood disorders with seasonal pattern, supporting the need for a dimensional approach to major depressive disorder and bipolar disorder. Significant percentage of patients with a primary diagnosis of major depressive disorder had seasonal pattern. Significant percentage of patients with a primary diagnosis of major depressive disorder reported (hypo)manic symptomatology. PMID: 33399494 [PubMed - as supplied by publisher]
