MOVE for Your MIND

Among the most promising interventions targeting both cognitive and functional decline, is Exercise. However, evidence regarding exercise interventions among seniors with cognitive impairment are inconclusive, likely due to challenges of recruitment and adherence. Alternatively, seniors with subjective cognitive decline (SCD), who are not yet meeting objective criteria of cognitive impairment, but have been shown to have twice the conversion rate to dementia compared with healthy seniors, are more likely to be motivated to participate and adhere to exercise interventions. Thus, exercise interventions in seniors with SCD may provide a window of opportunity for early prevention of dementia and falls. The investigators aim to test the effect of a group exercise (multi-task Jaques-Dalcroze Eurhythmics) and a simple home strength exercise program on change of cognitive function and the rate of falling among seniors with SCD.

Combined Model of Online Remote Interventions for Cancer-Related Cognitive Impairment

Cancer survival rates have increased dramatically in recent years. However, many survivors report cognitive decline following treatment, which significantly impairs their quality of life. Online cognitive training programs have shown promise in improving cognitive functions in cancer survivors, but most studies report limited impact of training on everyday function. A complementary treatment approach is functional treatment delivered by occupational therapists, which directly targets daily function. Combining the two approaches has the potential to overcome the limitations of both approaches, enabling improved cognitive functions and transfer to daily function. Remotely-administrated interventions further make treatment accessible and cost-effective. The current study is aimed at testing the efficacy of a novel, combined, remotely-delivered treatment approach: Cognitive Retraining and Functional Treatment(CRAFT), using a Randomized Controlled Trial (RCT) design. 90 cancer survivors will be randomly assigned to receive 15 weeks of either the combined treatment, computerized training only, or treatment-as-usual. Outcomes will be assessed at completion, and following 3 months of no contact, to test immediate and enduring effects of treatment. Baseline predictors for treatment response will be further assessed. Positive results in the proposed study could potentially change the therapeutic landscape for rehabilitation of cancer-related cognitive decline, which currently impair the lives of millions worldwide.

The Influence of Tai Chi Practice on Blood Pressure and Brain Health Among Older Adults With Hypertension (ACTION)

High blood pressure and poor cognitive function are two common health problems among older adults in the United States. They are also closely related because high blood pressure may lead to negative changes in brain structure and function such as poor brain blood flow that can cause poor cognitive function. Executive function is one type of cognitive function that let people plan and perform difficult tasks. It is commonly damaged by high blood pressure. It is also very important for older adults because they need good executive function to live on their own. Tai Chi is a good exercise option for older adults because it is safe, fun, and social. Research studies show that Tai Chi can reduce blood pressure and improve cognitive function, especially executive function. However, researchers do know if these heart and brain health benefits of Tai Chi are connected. In the ACTION study, researchers will first measure how a single session of Tai Chi followed by a 12-week online Tai Chi program with easy movements changes blood pressure and cognitive function, focusing on executive function. Then, researchers will test if these changes in heart and brain health are connected, and if they are connected through the changes in brain structure and function. Both the single session and 12-week online Tai Chi program will be practiced by a group of older adults with high blood pressure and normal cognitive function. They will be new to Tai Chi and not exercising regularly. The hypotheses of the ACTION study are that practicing Tai Chi is good for the heart and brain of older adults with high blood pressure. Specifically, relaxing Tai Chi with gentle movements will reduce blood pressure, and thereby improve cognitive function, particularly executive function.

Dopaminergic Dysfunction in Late-Life Depression

Late-Life Depression (LLD), or depression in older adults, often presents with motivational deficits, deficits in performance in cognitive domains including processing speed and executive dysfunction, and mobility impairments. This triad of findings implicate dopaminergic dysfunction as a core pathophysiologic feature in depression, and may contribute to cognitive decline and motor disability. Normal aging results in brain-wide dopamine declines, decreased D1/D2 receptor density, and loss of dopamine transporters. Although brain changes associated with depression and aging converge on dopamine circuits, the specific disturbances in LLD and how responsive the system is to modulation remain unclear. In this collaborative study between Columbia University /New York State Psychiatric Institute and Vanderbilt University Medical Center, investigators are testing integrative model that aging, in concert with pro-inflammatory shifts, decreases dopamine signaling. These signally changes affects behaviors supported by these circuits, in the context of age-associated cortical atrophy and ischemic microvascular changes, resulting in variable LLD phenotypes. Investigators propose a primary pathway where dopaminergic dysfunction in depressed elders contributes to slowed processing speed and mobility impairments that increase the effort cost associated with voluntary behavior. The central hypothesis of this study is that late-life depression is characterized by dysfunction in the dopamine system and, by enhancing dopamine functioning in the brain. By improving cognitive and motor slowing, administration of carbidopa/levodopa (L-DOPA) will improve depressive symptoms.
