Impact of Mild Behavioral Impairment on Longitudinal Changes in Cognition.

Background: To examine cross-sectional differences and longitudinal changes in cognitive performance based on the presence of mild behavioral impairment (MBI) among older adults who are cognitively healthy or have mild cognitive impairment (MCI).

Methods: Secondary data analysis of participants (n = 17 291) who were cognitively healthy (n = 11 771) or diagnosed with MCI (n = 5 520) from the National Alzheimer's Coordinating Center database. Overall, 24.

Mild behavioral impairment as a predictor of cognitive functioning in older adults.

Objective: To assess the influence of mild behavioral impairment (MBI) on the cognitive performance of older adults who are cognitively healthy or have mild cognitive impairment (MCI).

Methods: Secondary data analysis of a sample (n = 497) of older adults from the Florida Alzheimer's Disease Research Center who were either cognitively healthy (n = 285) or diagnosed with MCI (n = 212). Over half of the sample (n = 255) met the operationalized diagnostic criteria for MBI.

Neuropsychiatric symptoms as a distinguishing factor between memory diagnoses.

Objectives: To determine whether neuropsychiatric symptoms (NPS) are able to differentiate those with mild cognitive impairment (MCI) and dementia from persons who are cognitively healthy.

Methods: Multinomial and binary logistic regressions were used to assess secondary data of a sample (n = 613) of older adults with NPS. Analyses evaluated the ability to differentiate between diagnoses, as well as the influence of these symptoms for individuals with amnestic MCI (MCI-A), non-amnestic MCI (MCI-NA), and dementia compared with those who are cognitively healthy.

Mortality and Cause of Death in Younger Homeless Veterans.

Objectives: Increased mortality has been documented in older homeless veterans. This retrospective study examined mortality and cause of death in a cohort of young and middle-aged homeless veterans.

Methods: We examined US Department of Veterans Affairs records on homelessness and health care for 2000-2003 and identified 23 898 homeless living veterans and 65 198 non-homeless living veterans aged 30-54.
