Neuropsychiatric symptoms occur in the majority of persons with dementia over the course of the disease. These are the first population-based estimates for neuropsychiatric symptoms in MCI, indicating a high prevalence associated with this condition as well. These symptoms have serious adverse consequences and should be inquired about and treated as necessary. Study of neuropsychiatric symptoms in the context of dementia may improve our understanding of brain-behavior relationships.

Twenty-two percent of the participants aged 75 years or older had MCI. Mild cognitive impairment is a heterogeneous syndrome, where the MCI amnestic-type is less frequent than the MCI multiple cognitive deficits-type. Most of the participants with MCI had comorbid conditions that may affect their cognitive functions.

Sex and racial differences were not found, and VaD was higher than reported in other studies. These data provide new estimates of dementia incidence in a community sample for projection of future burden.

The development of MCI is associated with measurements of cognition and depression, racial and constitutional factors, and cerebrovascular disease. Early cognitive deficits seem to be a common denominator for the 2 forms of MCI; the presence of cerebrovascular disease and the APOE epsilon4 allele is associated with the amnestic type of MCI.

Copper Ridge is a long-term care facility that provides care for persons with dementia and their families from early diagnosis to end of life. A low-cost videoconferencing system was employed in the development of a comprehensive, integrated continuum of care for Copper Ridge residents by bridging long-term care with inpatient psychiatric care at Johns Hopkins Hospital. In this article, we discuss the Copper Ridge/Johns Hopkins telemedicine project and how its operation appears to have brought about a reduction in psychiatric admissions. Telemedicine projects using inexpensive technology over standard telephone lines can be successfully used in long-term care settings.
