Primary purpose: TREATMENT

Brief summary: Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and severe dementia associated with Alzheimer's disease (AD). In the United States about 20% of older adults have MCI. Loss of cognitive function in aging can have far-reaching and devastating impacts on functional status, independence, and quality of life. Unfortunately, the therapeutic options to slow progression of cognitive decline in aging are limited. Dual-task training; that which involves simultaneous cognitive and motor challenges, is a high-impact potential therapy to slow progressive loss of both motor and cognitive function in aging. The purpose of this trial is to examine the feasibility and therapeutic impact of a novel dual-task physical activity intervention on executive and motor functions among adults, 65 years or older, who have MCI. the investigative team anticipates that findings from this trial will inform development of larger community-based studies focused on improving function and ability to maintain independence in older age.

Detailed description: Mild cognitive impairment (MCI) is an intermediate stage between the expected cognitive decline of normal aging and severe dementia associated with Alzheimer's disease (AD). In the United States about 20% of older adults have MCI, and approximately 15% per year of those with MCI will progress to AD. With our rapidly aging society, we are approaching a public health crisis for which we are not fully prepared. Impaired cognitive function in aging can have far-reaching and devastating impacts on functional status, ability to maintain independence, and overall quality of life. Unfortunately, the therapeutic options to slow progression of cognitive decline in aging are limited.

Dual-task training that involves simultaneous cognitive and motor challenges improves certain domains of both cognitive and motor function in older adults with MCI. However, we do not yet know the optimal methods of delivering this high-impact potential therapy in community-based settings with unique limitations and strengths. Therefore, the aims are to; 1) test the feasibility of conducting a community-based dual-task (thinking while exercising) physical activity intervention among adults, 65 years or older, with MCI; and 2) examine the impact of dual-task training on attention and motor function among adults, 65 years or older, with MCI.

To accomplish these aims the investigators will conduct an 12-week, dual-task training program using the SmartFit Multisensory Fitness System (Oxnard, CA) among older adults with MCI. Our group-based training program involves two 1-hour training sessions per week, designed to simultaneously engage the mind and body, while promoting self-efficacy. Attention and motor function will be assessed prospectively.

The investigators anticipate that findings from this trial will inform development of methods to bring evidence-based, non-invasive therapies into communities in need, in order to preserve function, independence, and quality of life well into older age.
