title: Pica in the geriatric mentally ill: unrelenting and potentially fatal.
abstract: Pica has rarely been reported in patients with geriatric mental illness. The authors describe 3 male patients with pica in the geriatric unit of a state mental hospital. Two of these patients had a diagnosis of developmental delay with concomitant diagnoses of schizophrenia and schizoaffective disorder, respectively. The third patient was diagnosed with paranoid schizophrenia. In all 3 cases, pica started late in life and was unrelenting and unresponsive to psychotropic medications, with limited to no response to behavioral interventions. In the 2 patients who died, pica was implicated as the direct cause of death in 1 and the likely cause of death in the other. When pica occurs in elderly patients with mental illness, the risk of mortality should be taken into account in clinical management.
