Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Secondary Specific Aim 1: Determine the effect of the combined physical exercise and cognitive training on physical performance, anxiety and depressive symptoms, and quality of life of ICU survivors aged 50 and older. Hypotheses: In comparison to older ICU survivors randomized to attention control or either intervention alone, those randomized to 12 weeks of combined physical exercise and cognitive training will have higher physical performance as measured by short physical performance battery (SPPB) and two-minute step test, lower mood and anxiety symptoms as measured by Patient Health Questionnaire (PHQ-9) and Generalized Anxiety Disorder (GAD-7) scale, and higher quality of life as measured by the Medical Outcomes Study 36-item short form (SF-36) at 3 and 6-months post randomization.
Exploratory Aim 2: To examine the mechanisms of action of combined training. Hypothesis: At the completion of treatment, the combined intervention group will show reduced serum levels of CRP, IL-1, IL-6, IL-8, TNF-α, S-100β, and GFAP and increased levels of BDNF, VEGF, and IGF-1 compared to the attention control, or either intervention alone groups.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Two million older Americans suffer from an episode of delirium during their intensive care unit (ICU) stay. Presence of delirium predisposes the elderly to immediate in-hospital complications including a longer length of ICU and hospital stay, increased risk of in-patient mortality and elevated costs of care. In addition, ICU delirium is associated with long-term post-discharge complications such as development of cognitive impairment and dementia. Current advances in the management of critical illness have notably improved the survival rates among this vulnerable segment of older adults. However, increased survival comes at a cost with as many as 70% of older ICU survivors who had an episode of delirium suffering from subsequent cognitive impairment and dementia. At present, there are no effective and scalable recovery models to remediate ICU acquired cognitive impairment and its attendant elevated dementia or Alzheimer's disease risk.
The inability to develop efficacious interventions to reduce ICU acquired cognitive impairment may stem from a limited understanding of the link between acute brain dysfunction (delirium) and chronic brain dysfunction (ICU acquired cognitive impairment, dementia or Alzheimer's disease). The investigators propose a recovery intervention guided by the pathophysiologic mechanisms implicated in producing critical illness delirium and elevated risk of cognitive impairment. The intervention targets inflammation, glial dysfunction and astrocyte activation along with restoration of neurotrophic factors while training function directly across multiple cognitive domains to reduce the burden of cognitive impairment among ICU survivors of delirium.
Over the past five years, Indiana University Center for Aging Research has developed a research infrastructure focused on delirium and delirium associated cognitive impairment, encompassing the ICU and post-ICU periods. This includes developing a bio-repository of serum delirium biomarkers, ICU based delirium trials, and post-ICU exercise and cognitive therapy recovery models. Building upon prior work and based on the pathophysiologic mechanisms mentioned above, the investigators now propose a novel home-based combined physical exercise and cognitive training program for older ICU survivors to improve cognitive impairment.
The study team is proposing a 2x2 factorial design randomized controlled trial (RCT) called "Decreasing Alzheimer's Disease and Related Dementias after Delirium-Exercise and Cognitive Training (DDD-ECT)" to evaluate the efficacy of 12 weeks of combined physical exercise and cognitive training on the primary outcome of cognitive function among older ICU survivors who experienced delirium or subsyndromal delirium during their ICU stay. The investigators propose to deliver these interventions via a facilitator-led, small group format using internet-enabled, multiparty-videoconference delivered directly into the participants' homes to achieve the study aims listed in the summary.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Physical Exercise and Cognitive Training
Physical Exercise Intervention: The physical exercise portion of the combined intervention consists of 45 minutes of multi-modal physical exercise focused on seated aerobic and progressive resistance training designed to improve aerobic capacity, muscular strength and endurance consistent with current exercise recommendations. The study team will deliver 3 sessions per week for 3 months.
Cognitive Intervention: The cognitive portion of the combined intervention consists of a suite of 24 programs called Brain HQ developed by Posit Science Inc., organized into six categories: attention, speed, memory, people skills, intelligence, and navigation. The DDD-ECT trial will use 45-minute sessions of Brain HQ exercises. The modules are designed to improve time-order judgment, visual discrimination, spatial-match, forward-span, instruction-following, and memory.

Physical Exercise and Cognitive Control
Physical Exercise Intervention: The physical exercise portion of the combined intervention consists of 45 minutes of multi-modal physical exercise focused on seated aerobic and progressive resistance training designed to improve aerobic capacity, muscular strength and endurance consistent with current exercise recommendations.
