Korábbi kezelés

  • MR contraindications: Metal in the body, dental work other than fillings or gold, tattoos, metal injury, any other implant unless they are 100% plastic.
  • PET contradictions: participation in >1 research study in the past 12 months that included ionizing radiation exceeding 3 rem to the whole body (e.g., PET, CT). Standard of care imaging is not exclusionary.
  • History of chronic, recurrent mood or psychotic disorders (i.e., more than one non-reproductive-related mood episode prior to the perimenopausal index episode).
  • Current medication use (i.e., current psychotropics, current anti-hypertensives, current statins, current hormonal preparations, or frequent use of anti-inflammatory agents (> 10 times/month)). Women will be allowed to enroll who take medications without known mood effects (e.g. stable thyroid hormone replacement and occasional (< 5 times/month) use of Ambien)*;
  • Last menstrual period more than 12 months prior to enrollment;
  • Peanut allergy
    • all reported prescription medications will be reviewed and cleared by a study physician prior to a participant's enrollment;
    • participants will be given the opportunity to describe these conditions in the online screening survey. Reported conditions that are acute in nature and/or benign will be reviewed by a study physician and exclusions will be decided case-by-case. All chronic conditions will be exclusionary. For those where it is deemed that an exclusion does not apply, primary analyses will not be affected, but exploratory analyses will be conducted excluding these individuals
