PMDD could be categorized as
severe PMS
estrogen effects on NT
+ effect on 5HT- increased synthesis, 5HT1 receptors, binding affinity
progesterone effect on hormones
increased 5HT uptake and turnover
what are the pathophysiology theories of PMS/PMDD
Correlation of hormones and + central NT (5HT)
Greater susceptibility to normal cyclic changes in hormones or ratio of estrogen to progesterone
Progesterone key mediator of PMS/PMDD: allopregnanolone is a metabolite of progesterone and an agonist of GABAr
RF for PMS/PMDD
genetics, traumatic or major life events/ stressors, comorbidity with depression/ anxiety, psychosocial factors (ex- fewer social supports)
