Abstract
Neuropsychiatric disorders among elderly patients have received increasing attention with the aging of the population (Leuchter, 1985).Paranoid symptoms are a familiar problem to those involved in medical and social services for the elderly (Forsell and Henderson, 1998). However, Webster and Grossberg (1998) reported that one group of elderly psychiatric patients whose clinical characteristics are not well established are patients with late onset paranoid symptoms i.e. those who manifest paranoid symptoms after the age of 65.Because the major psychotic disorders responsible for the early onset paranoid symptoms, especially schizophrenia and mood disorders, typically have an onset in young adulthood, a question arises as to whether there may be etiologic differences in late-onset paranoid symptoms. The issue of differential diagnosis and demonstration of the risk factors is especially important with respect to treatment and prevention because some conditions producing psychosis may be curable with appropriate intervention (Webster and Grossberg, 1998).
