Preventing disability in older adults with mild cognitive impairment: A Strategy Training intervention study

摘要

Non-pharmacological interventions designed to change cognitive function in older adults with Mild Cognitive Impairment have shown mixed results. Few studied interventions directly address preclinical disability. Slowing changes in disability are critical preserve independence and health related quality of life in older adults with Mild Cognitive Impairment. In this study, we discuss the design of the trial, challenges encountered, and solutions generated to guide future trials designed to prevent the onset of disability among at-risk older adults. We compared Strategy Training to enhanced-usual care in 30 older adults with Mild Cognitive Impairment. We recruited 79.7% (n?=?188) of the potential participants through direct-to-consumer recruitment. We refined a three-step screening process, including a phone screen, initial in-person screening, and full in-person screening. This screening processes resulted in a high percentage of older adults completing the neuropsychological battery and adjudication of Mild Cognitive Impairment. Conducting a disability prevention among individuals without overt disability is a novel approach. Nevertheless, one of the greatest limitations to our project is the fact that follow-up is restricted to 1 year. Findings from this study can inform the design and conduct of future clinical trials that seek to slow progression of disability in older adults with Mild Cognitive Impairment.
