Summary
Interventions that affect many different aspects of human ability rather than just one aspect of human health are more likely to be successful in preventing and treating Alzheimer's disease (AD). Functional decline in AD is severely impacted by impaired ability to do physical actions while having to make decisions and concentrating, something scientists call motor-cognitive integration. Combined motor and cognitive training has been recommended for people with early AD, thus this study will use partnered, rhythmic rehabilitation (PRR), as an intervention to simultaneously target cardiovascular, social and motor-cognitive domains important to AD. PRR is moderate intensity, cognitively-engaging social dance that targets postural control systems, involves learning multiple, varied stepping and rhythmic patterns, and fosters tactile communication of motor goals between partners, enhancing social interaction's effect on cognition. Previous research demonstrates that PRR classes are safe and result in no injurious falls.
This study is a 12-month long Phase II single- blind randomized clinical trial using PRR in 66 patients with early AD. Participants with early AD will be randomly assigned to participate in PRR or a walking program for three months of biweekly sessions, followed by nine months of weekly sessions of PRR or walking. The overarching hypothesis is that PRR is safe, tolerable and associated with improved motor-cognitive function, and brain (neuronal), vascular (blood vessels) and inflammatory biomarkers that might affect function.
Description
For people with early Alzheimer's disease (AD), treatment options to prevent declined function are extremely limited, because AD affects many areas of function. In early AD, people may have trouble physically doing things while also thinking, which is necessary for many activities in daily life. This problem might be helped by doing activities that challenge the mind and the body at the same time. Partnered rhythmic rehabilitation (PRR), which targets fitness, cognition, mobility and social engagement and may prevent future functional problems in AD.
This is a phase II single-blind randomized clinical trial to assess the safety, tolerability, and efficacy of PRR in individuals in the early stages of AD, also called prodromal AD (pAD) . Participants will be randomly assigned to 90-minute PRR or WALK classes. Both interventions will receive equal contact and monitoring from study staff. Participants will have two phases of intervention. In the three-month Training phase, participants will be assigned to 20, biweekly (90-minute) lessons over 12 weeks. In the nine-month Maintenance phase, participants will attend weekly lessons at least 3 times per month. Participants will undergo either PRR or Walking Exercise (WALK) interventions for one year, which will use de-escalating doses: two times per week for three months (Training) and weekly for nine months (Maintenance).
The first study aim is to determine acceptability, safety, tolerability and satisfaction with PRR in pAD. The second aim is to determine a) efficacy of PRR vs. WALK for improving motor-cognitive integration in pAD; b) to identify sensitive endpoints to power a future phase III trial. The researchers will also explore potential mechanisms by which PRR affects pAD. These mechanisms include functional brain measures, vascular, and inflammation measures (arterial stiffness; cerebral perfusion, task functional magnetic resonance imaging [fMRI]; inflammatory markers: cytokines and chemokines, endothelial adhesion markers.
