Abstract: The incidence of primary hyperparathyroidism (PHPT) is about 21 cases per 100,000 person-years, and the disorder is usually caused by a solitary parathyroid adenoma. PHPT has traditionally been recognized by its characteristic symptoms, including urolithiasis (“stones”); osteopenia and osteoporosis (“bones”); abdominal cramping, nausea, and peptic ulceration (“moans”); and depression, anxiety, cognitive dysfunction, insomnia, confusion, and personality changes (“psychiatric overtones”). Although the pathogenesis of psychiatric symptoms in PHPT remains unclear, calcium is thought to figure prominently in determining changes in monoamine metabolism in the CNS, thereby modifying neurotransmission and resulting in alterations in mood and cognition. Generally, the psychopathology emerges after a prolonged period of subclinical hypercalcemia, but the correlation between symptom severity and degree of hypercalcemia is poor. Of note to the psychiatrist, lithium use has an absolute risk of 10% for PHPT, compared with a 0.1% risk in the general population. This is because lithium increases the calcium set point at which suppression of parathyroid hormone release occurs, thus causing an increase in parathyroid gland volume and hormone secretion.
