Can adrenal insufficiency cause symptoms that look like a psychiatric crisis?
In this episode, Noah and Eloise explore a difficult but important topic from the My Adrenal Life article “Adrenal Psychosis: When Cortisol Loss Affects the Brain.” The discussion looks at how severe cortisol deficiency can sometimes affect brain function in ways that resemble panic, paranoia, confusion, or even hallucinations.
Historically, even Thomas Addison’s original 1855 description of the disease mentioned neurological and emotional disturbances such as anxiety, delirium, and episodes of confusion. Yet over time, many of these symptoms faded from mainstream teaching, leaving a gap between textbook descriptions and real patient experiences.
The episode explains why this can happen.
The brain is an organ that depends on stable energy, circulation, and electrolyte balance. Cortisol plays a major role in maintaining those systems. When cortisol becomes severely deficient — whether in Primary adrenal insufficiency (Addison’s disease), Secondary AI, Tertiary AI, or steroid-induced adrenal suppression — the brain may be affected by several physiologic disruptions at once.
Noah and Eloise discuss three major factors that can contribute to severe neurologic symptoms:
• Hypoglycemia (low blood sugar), which can impair brain energy supply
• Hyponatremia (low sodium), which in primary adrenal insufficiency can lead to dangerous electrolyte imbalance
• Low blood pressure and reduced cerebral perfusion, affecting oxygen and nutrient delivery to the brain
When these factors occur together, the result can sometimes appear dramatic. Patients may experience confusion, agitation, severe brain fog, or a sense of disconnection from reality. In rare cases described in medical literature, severe electrolyte imbalance or metabolic instability has even produced hallucinations or psychosis-like symptoms.
Because these symptoms resemble psychiatric emergencies, people with adrenal insufficiency have historically been misdiagnosed with anxiety disorders, bipolar disorder, or other psychiatric conditions before the underlying endocrine problem was recognized.
Another challenge is that adrenal insufficiency can develop gradually. Before a full adrenal crisis occurs, many patients experience a prodromal phase where thinking becomes slower, concentration becomes difficult, emotions become unstable, or reality may feel “foggy” or unfamiliar.
For caregivers and families, this can be frightening. Sudden personality changes or confusion can appear emotional or behavioral when they are actually signs of severe physiologic stress.
The key message of this episode is validation and awareness. When brain function changes during adrenal instability, it does not reflect a character flaw or psychological weakness. It reflects metabolic disruption affecting the brain.
Understanding this connection can help patients, caregivers, and clinicians recognize warning signs earlier and treat the underlying physiologic problem before it progresses to adrenal crisis.
Most importantly, the episode emphasizes that when cortisol levels are restored and the body stabilizes, mental clarity often returns as well.
No one should have to face these experiences alone or feel ashamed of symptoms that are rooted in biology.
