“…In spring/summer, high hospitalization rates for manic episode (as principal reason for involuntary admission) are well stated, due to an increase in total sunshine hours and length of the average monthly days (Wang & Chen 2013;Abreu & Braganca 2015;Hochman et al 2016). Other studies showed, in addition to the main peak in spring/summer, a lower frequency of manic involuntary admissions in autumn (Cassidy & Carroll 2002;Lee et al 2002;Morken et al 2002;Volpe and Del Porto 2006;Lee et al 2007;Volpe et al 2010;Yang et al 2013;Geoffroy et al 2014). Furthermore, patients with bipolar disorder and seasonal-affective disorder have a higher light sensitivity compared to healthy controls and patients affected by major depressive disorder, as a result of melatoninergic, serotoninergic and dopaminergic neurotransmissions (Nathan et al 1999;Quera Salva et al 2011).…”

Objective: The aim of this study is to assess the prevalence of involuntary admissions with regard to seasonality and clinical associated features, in a sample of patients admitted to a psychiatric unit in a period of 24 months. Methods: All subjects consecutively admitted to the Psychiatric Inpatient Unit of the San Luigi Gonzaga Hospital, Orbassano (University of Turin, Italy) from September 2013 to August 2015 were recruited. Socio-demographic and clinical characteristics were collected. Results: Seven hundred and thirty admissions in psychiatric ward were recognized. The prevalence of involuntary admission was 15.4%. Patients with involuntary hospitalizations showed a higher education level, a higher prevalence of admission in spring/summer with a significant peak in June, a longer duration of hospitalization and a lower suicide ideation. Among involuntary admissions, physical restraint and suicide attempts were more prevalent during spring compared to the other seasons. Conclusions: Seasonality has an important role in the psychopathology of psychiatric disorders, particularly in bipolar and related disorder, and may represent an influencing factor in hospital admissions and hospitalizations. Seasonal pattern must be considered while managing diagnosis and treatment of mental disorders, with regard to prevention and psychoeducation of patients.

“…Similar to the Asian countries (Lee et al, 2002;Rajkumar and Sarkar, 2015) other tropical regions like Latin America also report increased recurrence rates for mania in the spring season (Volpe et al, 2010). The geographical vulnerability of the equatorial and the tropical zones such as Asia is postulated to cause prolonged summers and a longer exposure to sunlight compared with the rest of the World.…”

“…Therefore, the seasonal patterns for mood and behavior might be different from each other. We have already reported the seasonal pattern of fi rst manic episodes of bipolar affective disorder in Korea [11] . The purpose of this study was to investigate the association between GNB3 gene C825T SNP and seasonal variations in mood and behaviors in young male college students.…”

This study investigated the relationship between G-protein β₃ subunit (GNB3) C825T polymorphism and seasonal variation in 189 young male college students. The subjects were genotyped for C825T and were evaluated by the Seasonality Pattern Assessment Questionnaire. The Global Seasonality Score (GSS) between the three genotypes revealed a marginal difference. The heterozygotes showed significantly higher seasonal variations in GSS than the homozygotes. The prevalence of heterozygotes tended to be higher in seasonals compared with normal subjects, although it was not statistically significant. These results suggest that GNB3 C825T polymorphism tends to be related to seasonal variation in mood and behavior in the normal population.
