Clinical Trial Summary

This study will evaluate the efficacy of working memory training in older adults with amnestic mild cognitive impairment (MCI).

Description:

Working memory (WM) is the ability to hold information actively in mind and is fundamental for higher-order cognition. This pilot study aims to (1) evaluate the efficacy of WM training in older adults with MCI and (2) understand if and how it works. The study will use behavioral and brain imaging assessments to see whether WM training changes how participants learn and remember information. Functional magnetic resonance imaging (fMRI) and functional near infrared spectroscopy (fNIRS) methods will be used. The study will also use cognitive tests and questionnaires to determine whether participants' cognitive abilities change with training. The study will enroll participants with a diagnosis of MCI as well as cognitively intact older adults (healthy controls, HC).

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Gains in WM training task performance	Analyses of WM performance for each training session indexed as the mean set-size achieved during each training session for each participant	2 weeks
Primary	Changes in brain activation within the WM network	Univariate analyses via fMRI and fNIRS, respectively, using units of brain activation (i.e., contrast estimates)	2 weeks
Secondary	Changes in criterion (fMRI) WM task performance	Analyses of WM performance indexed as percent accuracy	2 weeks
Secondary	Changes in functional connectivity within and between canonical brain networks	Graph theory analysis via fMRI and fNIRS, respectively, using measures of connectivity strength (i.e., correlation coefficients)	2 weeks
