Episodic Memory and Executive Function Are Differentially Affected by Retests but Similarly Affected by Age in a Longitudinal Study of Normally-Aging Older Adults.

Episodic memory and executive function are two cognitive domains that have been studied extensively in older adults and have been shown to decline in normally-aging older individuals. However, one of the problems with characterizing cognitive changes in longitudinal studies has been separating effects attributable to normal aging from effects created by repeated testing or practice. In the present study, 166 people aged 65 and older were enrolled over several years and tested at least 3 times at variable intervals ( = 3.

Guardianship Before and Following Hospitalization.

When ethics committees are consulted about patients who have or need court-appointed guardians, they lack empirical evidence about several common issues, including the relationship between guardianship and prolonged, potentially medically unnecessary hospitalizations for patients. To provide information about this issue, we conducted quantitative and qualitative analyses using a retrospective cohort from Veterans Healthcare Administration. To examine the relationship between guardianship appointment and hospital length of stay, we first compared 116 persons hospitalized prior to guardianship appointment to a comparison group (n = 348) 3:1 matched for age, diagnosis, date of admission, and comorbidity.

Help Me Understand: Providing Palliative Care to Individuals With Serious Mental Illness.

Individuals with serious mental illness (SMI) have shortened life expectancy with increased risk of developing comorbid medical illnesses. They might have difficulty accessing care and can be lost to follow-up due to complex socioeconomic factors, placing them at greater risk of dying from chronic or undiagnosed conditions. This, in combination with stigma associated with SMI, can result in lower quality end-of-life care.

End-of-Life Care for Persons Under Guardianship.

Context: Guardians are surrogate decision makers appointed by a court when other health care decision-makers are unable, unwilling, or unavailable to make decisions. Prior studies suggest that persons under guardianship may experience delays in transitions of care.

Objectives: To compare quality of end-of-life care for persons under guardianship to a matched group on objective indicators and to identify narrative themes characterizing potential obstacles to quality end-of-life care.

Differences between young and older adults in unity and diversity of executive functions.

Miyake and colleagues (2000) identified three independent but correlated components of executive function in young adults - set shifting, inhibition, and updating. The present study compared the factor structure in young adults to two groups of older adults (ages 60-73 and 74-98). A three-factor model of shifting, inhibition and updating was confirmed in young adults, but the factors were weakly or uncorrelated.

Working memory predicts subsequent episodic memory decline during healthy cognitive aging: evidence from a cross-lagged panel design.

Aging adults experience declines in working memory and episodic memory, however, it is unclear how these declines operate over time. Decreased working memory may be associated with early changes in episodic memory, by reducing older adults' ability to meaningfully integrate new information into pre-existing schemas and recall information without the assistance of cues. Given the increased prevalence of Alzheimer's disease, and concerns based on subjective memory changes, it is important to understand how these processes interact over time.

Social cognition and the course of social functioning in first-episode psychosis.

Background: Social functioning deficits greatly affect individuals with psychotic disorders resulting in decreased ability to maintain relationships, jobs and pursuit of educational goals. Deficits in social cognition have been hypothesized to be an important contributor to these deficits in social functioning. In particular, 5 domains of social cognition have been suggested to be relevant in the study of psychotic disorders: (1) attributional style, (2) emotion recognition, (3) social knowledge, (4) social perception and (5) theory of mind.

Self-reference and emotional memory effects in older adults at increased genetic risk of Alzheimer's disease.

The present study investigated whether cognitively healthy older adults who are carriers of the ε4 allele of apolipoprotein E, the most prevalent genetic risk factor for late-onset Alzheimer's disease, benefit from self-referential processing and emotional processing to the same degree as noncarriers of this gene. Participants encoded emotional and nonemotional narratives using a baseline-orienting task, semantic elaboration, or imagination-based self-referential processing and then completed a recognition memory test. Both groups of older adults showed enhanced recognition memory for narrative information following self-referential processing relative to semantic elaboration, and the magnitude of this memory effect was not affected by ε4 status.
