When Hormones Trigger Mania: A Rare Case Shows How the Body Can Hijack the Mind

A Case Study From Colombia Reveals How Hormonal Imbalances Can Fuel Psychotic Mania — and Why Endocrine Health Matters for Bipolar Disorder

Most conversations about manic episodes focus on stress, sleep loss, or medication changes. But a case study published in Cureus points to something less discussed: hormones.

A 33-year-old patient in Colombia with congenital adrenal hyperplasia (CAH) and bipolar I disorder was admitted to a psychiatric hospital after five days of escalating mania, complete with grandiose delusions, auditory hallucinations, and psychomotor agitation.

The patient had been on long-term prednisolone — a corticosteroid — to manage CAH since birth. Lab work revealed severely low cortisol, elevated adrenocorticotropic hormone, and testosterone levels more than four times the expected range. Researchers concluded that the combination of enzyme deficiency and chronic steroid exposure created a dual mechanism of hormonal disruption: Hypothalamic-Pituitary-Adrenal axis suppression and neurosteroid imbalance, both feeding the manic episode.

Standard psychiatric medications were only partially effective. Lithium had to be discontinued due to kidney problems. It was only after 12 sessions of electroconvulsive therapy that the patient stabilized, with doctors attributing the improvement in part to ECT’s ability to reset HPA axis regulation.

The Science of Hormones and Mania

This case is unusual, but the underlying principle is not. A large-scale clinical study published in Translational Psychiatry found distinct hormonal signatures during manic episodes: elevated testosterone, estradiol, progesterone, and inflammatory markers, alongside suppressed adrenocorticotropic hormone. The patterns differed by sex and age, but the takeaway was consistent — hormonal shifts are not bystanders during mania. They are active participants.

Postpartum mania offers another window into this connection. Research estimates that nearly 40 percent of women with bipolar I experience mood relapse after childbirth, with the rapid drop in reproductive hormones acting as a trigger.

Elevated cortisol levels have been found in women who develop postpartum psychosis compared to those who remain stable. And thyroid dysfunction, which often accompanies hormonal upheaval, is a known destabilizer of mood in bipolar disorder.

The emerging picture is that it is not always abnormal hormone levels that cause problems. It is the change — the sudden shifts — that the bipolar brain struggles to absorb.

What This Means

For people living with bipolar disorder, this research underscores something that often gets overlooked: endocrine health matters. Thyroid panels, cortisol levels, and reproductive hormone changes are not separate from psychiatric stability. They are part of it.

If you are managing bipolar disorder and experiencing hormonal changes — whether from medication, aging, pregnancy, or an underlying condition — that information belongs in the conversation with your treatment team.

A note from Jayne Millerton: We spend so much time talking about the psychological triggers of mania — stress, sleep, life events — that we forget the body has its own levers. Hormones are invisible until they are not. If something feels off physically and your mood is shifting, do not assume they are unrelated. Push for the bloodwork. Ask the questions. Your psychiatrist and your endocrinologist should be talking to each other.
