Genetic linkage studies have not adequately looked at the bipolar/unipolar issue, but several report linkage to bipolar disorder on a number of chromosomes(Potash et al., 2003; Mathews and Reus, 2003). One study reports a genetic overlap betweenbipolar and depressive disorder (Hashimoto et al., 2005). Studies also report an overlapbetween bipolar disorder and schizophrenia (Bramon and Sham, 2001). The findings areinconsistent, however, in large part due to poorly defined phenotypes including failing toconsider the relationship between bipolar disorder and melancholia.76 Goodwin and Jamison (1990, p. 65).77 Abrams and Taylor (1974).78 Dorz et al. (2003).79 These studies are numerous. As examples, see: Goldberg et al. (2004); Maj et al. (2003);Marneros and Goodwin (2005).80 Angst and Preisig (1985); Mitchell and Malhi (2004).81 Numerous studies report this. As examples see: DelBello et al. (2003); Akiskal et al.
