“…Despite such findings with exogenously administered DHEA(S), the role of endogenous DHEA(S) in neuropsychiatric illness in humans and in MDD in particular, remain unclear. Previous findings in depression have found DHEA and/or DHEA-S concentrations to be decreased (Michael et al, 2000; Mocking et al, 2015; Morgan et al, 2010; Zhu et al, 2015), increased (Assies et al, 2004; Kurita et al, 2013; Morita et al, 2014; Takebayashi et al, 1998), or unchanged (Fabian et al, 2001; Kurita et al, 2013; Markopoulou et al, 2009; Mocking et al, 2015; Paslakis et al, 2010; Romeo et al, 1998) (also reviewed in Maninger et al ., 2009) in depression, compared to non-depressed controls. The relationship between endogenous serum DHEA(S) levels and likelihood of antidepressant-associated remission also remain unclear.…”
