Mania in a case of hyperparathyroidism.
Psychiatric manifestations of primary hyperparathyroidism are mediated by hypercalcemia. To date, most evidence indicates that hypercalcemia and increased cerebrospinal-fluid calcium levels produce depression symptoms. Presented here is a case report of a 52-year-old woman in a manic state. She had no psychiatric history but had substantially elevated parathyroid hormone levels and hypercalcemia. On the basis of emerging evidence that calcium channel-blockers effectively treat mania, the authors propose that elevated calcium levels may act through multiple mechanisms or on various regions of the brain to produce a spectrum of psychiatric symptoms that should now include mania as a possibility.
