Cognition-oriented treatments for older adults: A systematic review of the influence of depression and self-efficacy individual differences factors.

The increasing prevalence of cognitive decline, mild cognitive impairment (MCI), and dementia with the aging population has led to scrutiny of the efficacy of cognition-oriented treatments (COTs) aiming to maintain functioning, and delay or prevent further cognitive decline. However, little is known regarding the role of individual differences patient-variables (such as depression, self-efficacy, and motivation) in moderating the efficacy of COTs. This systematic review aimed to identify and analyze COT trials which investigated the relationship between differences in these patient-variables and intervention outcomes for older adults across healthy, MCI, and dementia populations.

Reliability and Validity of the Sit-to-Stand as a Muscular Power Measure in Older Adults.

The study aims were to analyze the reliability and validity of the GymAware™ linear position transducer's velocity and power measures during the sit-to-stand, compared with the Dartfish 2D videography analysis, and to assess the relationship of age and handgrip strength with velocity and power in 48 older men and women (77.6 ± 11.1 years).

Relationship between physical and cognitive performance in community dwelling, ethnically diverse older adults: a cross-sectional study.

Background: Regular exercise training stimulates physiological adaptations to improve physical performance, reduce chronic disease risk, and slow age-related cognitive decline. Since the physiological mechanisms responsible for aging-associated cognitive decline are not yet fully understood, and training-induced physiological adaptations responsible for performance measure improvements are specific to the type (aerobic vs. strength) and intensity of training, studies are needed to assess the relationships between physical performance measures and cognitive performance in older adults.

Meta-Analysis of the Effects of Computerized Cognitive Training on Executive Functions: a Cross-Disciplinary Taxonomy for Classifying Outcome Cognitive Factors.

The growing prevalence of neurodegenerative disorders associated with aging and cognitive decline has generated increasing cross-disciplinary interest in non-pharmacological interventions, such as computerized cognitive training (CCT), which may prevent or slow cognitive decline. However, inconsistent findings across meta-analytic reviews in the field suggest a lack of cross-disciplinary consensus and on-going debate regarding the benefits of CCT. We posit that a contributing factor is the lack of a theoretically-based taxonomy of constructs and representative tasks typically used.
