Glutamate in the medial prefrontal cortex in the early postpartum

  • Author / Creator

  • Risk factors for postpartum depression (PPD) include history of a major depressive episode, premenstrual dysphoric disorder, or a prior episode of PPD. Fluctuations in estrogen, progesterone, and neuroactive steroids occur in the postpartum, and these molecules act as modulators of a number of neurotransmitter systems, including that of glutamate (Glu). Recent investigations demonstrate alterations in brain Glu levels in mood disorders, and fluctuations in brain Glu have been demonstrated in response to hormone changes over the menstrual cycle. Using magnetic resonance spectroscopy to measure Glu in the medial prefrontal cortex (MPFC) in the early postpartum, the studies presented in this thesis demonstrate decreases in MPFC Glu levels compared to the follicular phase of the menstrual cycle (FP), and in women with risk factors for PPD compared to women without risk factors. Alterations in MPFC Glu occurring in the early postpartum may be related to the development of PPD.
