M. Rosenthal et al., PRIMARY HYPERPARATHYROIDISM - NEUROPSYCHIATRIC MANIFESTATIONS AND CASE-REPORT, Israel journal of psychiatry and related sciences, 34(2), 1997, pp. 122-125
We describe an elderly patient with primary hyperparathyroidism and de
mentia who was admitted to a psychogeriatric department because of del
usions of new onset. While hospitalized he had three episodes of delus
ions that coincided with mild hypercalcemia. Treatment for the hyperca
lcemia resulted in rapid remission of the delusional state, but did no
t induce any change in his cognitive abilities or in the severity of d
ementia. We review the relevant literature and offer recommendations f
or treatment and follow-up of elderly patients with hyperparathyroidis
m associated with a delusional state.
