Interventions

  • Transdermal Estradiol — DRUG
    Participants will be randomized to receive transdermal estradiol (100μg/day) patch for 3 weeks.
  • Micronized Progesterone — DRUG
    Participants will receive an additional week of micronized progesterone (200 mg/day) at the end of the study to precipitate menstruation.
  • Matching Placebo Patch — DRUG
    Participants will be randomized to receive a transdermal estradiol-matching placebo patch for 3 weeks
  • Raclopride C11 — DRUG
    All Participants will receive two PET-MR scans using \[11C\]raclopride IV as the tracer. The first scan will occur at baseline and the second at post treatment after 3 weeks.

Study Details

This proposal will examine the effects of estradiol administration on perimenopausal-onset (PO) anhedonia and psychosis symptoms as well as on brain function using simultaneous positron emission tomography and functional magnetic resonance imaging (PET-MR).

Arms

  • Experimental: Perimenopausal women with mild-to-moderate anhedonia + absent-to-mild psychosis, active group
    Participants will be randomly assigned to take 100 μg/day of transdermal estradiol for 3 weeks followed by 1 week of combined 100 μg/day of transdermal estradiol and 200 mg/day progesterone.
  • Experimental: Perimenopausal women with mild-to-moderate anhedonia + absent-to-mild psychosis, placebo group
    Participants will be randomly assigned to receive a matching placebo patch for 3 weeks.
  • Experimental: Perimenopausal women with mild-to-moderate anhedonia + moderate psychosis, active group
    Participants will be randomly assigned to take 100 μg/day of transdermal estradiol for 3 weeks followed by 1 week of combined 100 μg/day of transdermal estradiol and 200 mg/day progesterone.
  • Experimental: Perimenopausal women with mild-to-moderate anhedonia + moderate psychosis, placebo group
    Participants will be randomly assigned to receive a matching placebo patch for 3 weeks.
  • Experimental: Perimenopausal women with high anhedonia + absent-to-mild psychosis, active group
    Participants will be randomly assigned to take 100 μg/day of transdermal estradiol for 3 weeks followed by 1 week of combined 100 μg/day of transdermal estradiol and 200 mg/day progesterone.
  • Experimental: Perimenopausal women with high anhedonia + absent-to-mild psychosis, placebo group
    Participants will be randomly assigned to receive a matching placebo patch for 3 weeks.
  • Experimental: Perimenopausal women with high anhedonia + moderate psychosis, active group
    Participants will be randomly assigned to take 100 μg/day of transdermal estradiol for 3 weeks followed by 1 week of combined 100 μg/day of transdermal estradiol and 200 mg/day progesterone.
  • Experimental: Perimenopausal women with high anhedonia + moderate psychosis, placebo group
    Participants will be randomly assigned to receive a matching placebo patch for 3 weeks.
