Estrogen Variability and Irritability During the Menopause Transition
Study Details
Study Description
Brief Summary
Women in the menopause transition (perimenopause) experience substantial day-to-day variability in estradiol and have a 2-4-fold increase in major depression risk. About 40% of perimenopausal women are susceptible to the emergence of affective symptoms tied to changes in estradiol. Among the perimenopausal women with affective impairment, most report irritability, not "depression," is their primary source of impairment and distress. The purpose of this research is to determine the neurophysiologic basis of susceptibility to estradiol fluctuations and irritability symptoms in perimenopausal women.

Detailed Description
Using a within-subjects, cross-over design and transdermal estradiol to stabilize estradiol fluctuations (and increase levels) the investigators will test if neural dynamics (oscillatory activity in the theta and beta frequencies assessed via EEG) associated with key constructs of irritability (attentional bias to threat and frustration to non-reward) represent a biomarker target of irritability symptom response to transdermal estradiol.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Estradiol, Then Placebo Participants will first receive 0.1 mg/day of transdermal estradiol patch for 3 weeks. After a washout period of 3 weeks, participants will then receive transdermal placebo patch (matching transdermal estradiol 0.1 mg/day patch) for 3 weeks. Upon completion of the second intervention, all participants will receive 200 mg/day of progesterone for 10 days. |
Drug: Estradiol Patch, 0.1 mg/24 Hours Weekly Transdermal Film, Extended Release
0.1 mg/day transdermal patch administered for 3 weeks
Drug: Placebo
Estradiol-matched placebo patch administered for 3 weeks
Drug: Progesterone 200 mg
200 mg tablet administered by mouth once per day for 10 days after completion of the experimental phase of the study

Outcome Measures
Primary Outcome Measures
- Mean IDAS Ill Temper Scale Score Over Time [up to Week 13]
The 5-item ill temper scale of the Inventory of Depression and Anxiety Symptoms (IDAS) will be the primary measure of irritability symptom severity. Each symptom item is rated 1 (not at all) to 5 (extremely). The total IDAS ill temper scale score may range from 5-25. Higher scores indicate more severe irritability symptoms. The average daily irritability (IDAS) score over 1 week (7 days) will be assessed at baseline (Week 4), the last week of Condition 1 (Week 7), and the last week of Condition 2 (Week 13).
Secondary Outcome Measures
- Theta Oscillatory Activity (4-8 Hz) In Response To Dot Probe Task (Indexing Threat) Over Time [up to Week 13]
Participants will complete the Dot Probe Task while EEG is recorded to examine brain responses (theta oscillations) to threat. During the task, participants will be presented with a pair of faces on each side of the screen. In anger trials, one face is angry and the other is neutral. The pair of faces is followed by an asterisk, half of the time presented on the same side as the angry face and half of the time presented on the side of the neutral face. Trials will be angry-neutral, happy-neutral, and neutral-neutral. Theta recorded at the frontal midline electrode during the different task conditions will be assessed at baseline (Week 4), Condition 1 (Week 7), and Condition 2 (Week 13).
- Beta Oscillatory Activity (13-30 Hz) In Response To Affective Posner Paradigm (probing Frustration) Over Time [up to Week 13]
Participants will complete the Affective Posner Paradigm while EEG is recorded to examine brain activity (beta oscillations) during frustrating task events. The Affective Posner Paradigm is a reward task designed to measure frustration to non-reward, consisting of three runs with varying degrees of reward as the participant performs the task. Beta oscillatory activity during the three task conditions will be assessed at baseline (Week 4), Condition 1 (Week 7), and Condition 2 (Week 13).
