Parathyroid Paranoia: Unveiling Psychosis in Hyperparathyroidism

Area of Science:

• Endocrinology
• Psychiatry
• Medical Case Reports

Background:

• Primary hyperparathyroidism (PHPT) is a condition that can lead to hypercalcemia.
• Hypercalcemia has been anecdotally linked to psychiatric disturbances, including psychosis.
• The interplay between endocrine disorders and mental health requires further investigation.

Observation:

• A 28-year-old male with a history of cannabis use presented with new-onset mood instability, bizarre behavior, and functional decline.
• Initial psychiatric evaluation revealed symptoms suggestive of psychosis.
• Laboratory tests identified significant hypercalcemia, prompting further endocrine investigation.

Findings:

• Endocrine workup confirmed the diagnosis of primary hyperparathyroidism.
• Following surgical removal of the parathyroid adenoma (parathyroidectomy), the patient's psychotic symptoms completely resolved.
• The patient was able to discontinue all psychotropic medications post-surgery.

Implications:

• This case underscores the importance of considering and screening for organic causes, such as PHPT, in patients presenting with new-onset psychotic symptoms.
• Early recognition and management of underlying endocrine disorders can lead to significant psychiatric improvement and potentially obviate the need for long-term psychotropic treatment.
• Integrating endocrine and psychiatric care is crucial for comprehensive patient management, especially in individuals with co-occurring substance use disorders.
