“…The most commonly reported finding is a rise in mania admissions in the spring and summer months (Hare and Walter, 1978;Myers and Davies, 1978;Mulder et al, 1990;Takei et al, 1992;Suhail and Cochrane, 1998;Lee et al, 2007;Amr and Volpe, 2012) and a drop during wintertime (Myers and Davies, 1978;Lee et al, 2007;Amr and Volpe, 2012). Another frequent finding is that winter (Modai et al, 1994;Suhail and Cochrane, 1998;Avasthi et al, 2001;Lee et al, 2007;Amr and Volpe, 2012), as well as spring and autumn (Eastwood and Stiasny, 1978;Frangos et al, 1980;Silverstone et al, 1995;Morken et al, 2002) are the seasons when depressive episodes appear more often.…”
