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.
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.

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.
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.
Objectives: In this analysis of a cohort of older homeless veterans, we examined psychosocial, health, housing, and employment characteristics to identify predictors of mortality.
Method: Our sample of 3,620 older veterans entered Veteran Affairs homeless programs in years 2000-2003. Fifteen variables from a structured interview described this sample and served as predictors.
Objective: National Death Index data were examined to describe mortality patterns among older veterans who are homeless.
Methods: Homelessness and health care records from the U.S.
Objective: This study examined age-related differences in general medical and mental health risk factors for veterans participating in the U.S. Department of Veterans Affairs (VA) Grant Per Diem (GPD) transitional supportive housing program.

Background/aims: Verbal fluency patterns can assist in differential diagnosis during neuropsychological assessment and identify individuals at risk for developing Alzheimer's disease (AD). While evidence suggests that subjects with AD perform worse on category fluency than letter fluency tasks, the pattern in mild cognitive impairment (MCI) is less well known.
Methods: Performance on the Controlled Oral Word Association Test (COWAT) and Animal fluency was compared in control, amnestic MCI, non-amnestic MCI, and AD groups.
Purpose: To understand the needs and challenges encountered by older homeless veterans.
Methods: We conducted six focus groups of older veterans, two focus groups, and one semi-structured interview of VA staff liaisons, and two focus groups and one semi-structured interview of housing intervention providers.
Results: Major themes for older veterans: 1) negative homelessness experience; 2) benefits of the structured transitional housing program; 3) importance of peer outreach; and 4) need for age-tailored job placement programs.
Objectives: In this retrospective longitudinal cohort study, we examined the impact of dental care on outcomes among homeless veterans discharged from a Department of Veterans Affairs (VA) transitional housing intervention program.
Methods: Our sample consisted of 9870 veterans who were admitted into a VA homeless intervention program during 2008 and 2009, 4482 of whom received dental care during treatment and 5388 of whom did not. Primary outcomes of interest were program completion, employment or stable financial status on discharge, and transition to permanent housing.
Little is known about the impact of hurricanes on people who are homeless at the time a disaster occurs. Although researchers have extensively studied the psychosocial consequences of disaster produced homelessness on the general population, efforts focused on understanding how homeless people fare have been limited to a few media reports and the gray literature. In the event of a hurricane, homeless veterans may be at increased risk for negative outcomes because of their cumulative vulnerabilities.

Objective: To extend the psychometric study of the Cognitive Change Checklist (3CL) by examining the reliability, factor structure, and external correlates of 3CL informant and self-report ratings in community-dwelling adults. We also conducted receiver operating characteristic analyses examining rating scores from this normative sample with those of clinical samples.
Design: Scale reliability and validity study.

Objective: Issues regarding the readability of self-report assessment instruments, methods for establishing the reading ability level of respondents, and guidelines for development of scales designed for marginal readers have been inconsistently addressed in the literature. A recent study by McHugh and Behar (2009) provided new findings relevant to these issues. McHugh and Behar calculated indices of readability separately for the instructions and the item sets of 105 self-report measures of anxiety and depression.

Methods: We longitudinally evaluated 269 elderly subjects who did not meet formal criteria for MCI at baseline but had: (1) a clinical history suggesting MCI without neuropsychological deficits (PreMCI-Clinical); or (2) neuropsychological deficits on one or more memory measures in conjunction with a negative clinical examination (amnestic PreMCI-NP) or were normal on both neuropsychological and clinical examination.
Results: The rate of progression to MCI or dementia over an average of 2- to 3 years was 3.
Objective: An important distinction in models of housing for the homeless is whether programs that require abstinence prior to program admission produce better outcomes than unrestricted programs. Data from a large transitional housing program were used to compare client characteristics of and outcomes from programs requiring abstinence at admission and programs not requiring abstinence.

Better tools for assessing cognitive impairment in the early stages of Alzheimer's disease (AD) are required to enable diagnosis of the disease before substantial neurodegeneration has taken place and to allow detection of subtle changes in the early stages of progression of the disease. The National Institute on Aging and the Alzheimer's Association convened a meeting to discuss state of the art methods for cognitive assessment, including computerized batteries, as well as new approaches in the pipeline. Speakers described research using novel tests of object recognition, spatial navigation, attentional control, semantic memory, semantic interference, prospective memory, false memory and executive function as among the tools that could provide earlier identification of individuals with AD.

Extensive research supports the use of informant ratings in diagnosing dementia. In comparison, far fewer studies have examined the use of informant ratings in identifying mild cognitive impairment (MCI), a state that occurs as healthy older adults make the gradual transition to dementia. A review of available studies that have examined discrepancies between MCI patient and informant reports has for the most part demonstrated that informant ratings reveal greater loss of everyday functional ability and cognitive competency.

The authors compared the strength of this biomarker with performance on four memory measures and examined the influence of demographic factors including age, level of education, and primary language (English or Spanish).
Methods: The Hopkins Verbal Learning Test-revised, Fuld Object Memory Evaluation (FOME), delayed memory for a story passage, and delayed visual reproduction of the Wechsler Memory Scale-revised tests were administered to 281 subjects who were diagnosed as having no cognitive impairment, mild cognitive impairment (MCI), impaired non-MCI, or dementia.
Objective: A growing body of research supports the value of mental health intervention to treat people affected by disasters. This study used a mixed-methods approach to evaluate pre- and posthurricane mental health service use in Florida nursing homes.
Methods: A questionnaire was administered to 258 directors of nursing, administrators, and owners of nursing homes, representing two-thirds of Florida's counties, to identify residents' mental health needs and service use.
We conducted a cross-validation study of the Florida Cognitive Activities Scale (FCAS) in a sample of heterogeneously diagnosed elderly participants in the Florida Alzheimer's Disease Research Center. FCAS scales were found to be significantly correlated with neuropsychological measures and with ratings of medial temporal atrophy (MTA). The pattern of significant differences in FCAS scores among groups of normals, those with mild cognitive impairment, and early-stage Alzheimer disease cases suggests that the cognitive activities tapped by the FCAS are affected throughout disease progression in the same way as the neuropsychological performance measures.

A previous study demonstrated that the checklist met criteria for reliability and validity in characterizing cases of mild cognitive impairment (MCI) and early dementia in a memory disorder clinic sample. In this study we examined further the reliability, validity, and efficacy of the 3CL in distinguishing among groups of normal individuals, those with cognitive complaints, amnestic and non-amnestic MCI cases, and early-stage demented individuals.
View Article and Find Full Text PDFObjective: There is ample evidence to support an informant-based approach in screening efforts for the identification of cases of Mild Cognitive Impairment and early Alzheimer disease, but existing instruments are not maximally designed to capture recent changes in cognitive status of the types seen in these disorders. The authors describe the construction of a multiscale informant rating checklist (Cognitive Change Checklist; 3CL) designed to be sensitive to the earliest stages of cognitive decline associated with degenerative dementias.
Design: Scale development, reliability, and validity study.
