The assessment and treatment of psychiatric symptoms in persons with cognitive dysfunction are becoming increasingly important. Prevalence estimates of dementia in the United States range from 5% in those aged 71 to 79 years to 25% to 50% in those 90 or older.
Dementia is characterized as a progressive and chronic decline in cognitive function, not limited to memory impairment, which significantly interferes with baseline daily functioning and frequently involves behavioral disturbances. It is known that behavioral problems in dementia negatively affect patients and caregivers. These disturbances lead to institutionalization, increased costs and caregiver burden, and a poorer prognosis.
