A hip replacement triggered primary adrenal insufficiency and hyponatremia, causing complex psychopathology including delusions and depression. Treatment with hormone replacement normalized mood and cognition, resolving psychiatric symptoms.
Area of Science:
- Endocrinology
- Psychiatry
- Geriatrics
Background:
- Complex psychopathology can arise from the interplay of trauma, endocrine disorders, and infection.
- Elderly patients, especially after surgery, may present with atypical psychiatric symptoms.
Observation:
- An 82-year-old woman developed fluctuating cognitive impairment, delusions, and severe depression post-hip replacement, associated with hyponatremia.
- Recurrent urinary tract infections (UTIs) coincided with persistent hyponatremia and psychiatric symptoms.
- Primary adrenal insufficiency was diagnosed via Synacthen test due to declining cortisol levels.
Findings:
- Treatment with lifelong hormone substitution normalized serum sodium, improved mood, cognition, and resolved psychotic features.
- The patient's psychopathology was hypothesized to be induced by hypoadrenalism, potentially triggered by hip surgery and exacerbated by UTIs.
- While hyponatremia is known to cause delirium, its association with affective disorders in this context is rare.
Implications:
- Highlights the importance of considering endocrine disorders, particularly adrenal insufficiency, in elderly patients with unexplained psychiatric symptoms post-surgery.
- Suggests a potential link between surgical trauma, hypoadrenalism, recurrent infections, and complex psychopathology.
- Underscores the need for comprehensive diagnostic workups in geriatric psychiatric cases to identify underlying medical conditions.

Adrenal Gland Disorders
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss.

Anxiety: Overview
Individuals with anxiety often experience a range of physical and emotional symptoms, including sweating, trembling, tachycardia, and disturbances in sleep patterns. These symptoms vary in intensity and frequency but are generally disruptive and distressing.
Hormones of the Adrenal Glands
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...
