A 43-year-old perimenopausal woman presents with recurrent relapse episodes despite repeated engagement in residential and outpatient treatment. She is professionally successful, physically active, and externally high functioning. Relapses are abrupt, severe, and episodic, often following periods of perceived stability. Traditional relapse formulations have focused on psychological constructs—shame, perfectionism, and boundary collapse—yet repeated interventions have failed to produce durable remission.
A key clinical observation emerges only after longitudinal review: relapse episodes consistently occur during the late luteal phase. Subsequent evaluation leads to a diagnosis of premenstrual dysphoric disorder (PMDD) within the broader context of perimenopause. Treatment is expanded to include cycle tracking and targeted hormonal regulation alongside standard addiction care. With stabilization of hormonal variability, relapse frequency resolves. The patient remains abstinent at three years.
This case highlights a recurrent clinical blind spot: endocrine instability as a primary driver of relapse vulnerability.
