About this trial

Older adults at risk for dementia show a variety of cognitive deficits, which can be ameliorated by different cognitive training (CT) exercises. The best combination of CT exercises is unknown. The aim is to discover the most efficacious combination of CT exercises as compared to cognitive stimulation (which will serve as a stringent, active control) to modify the functional trajectories of older adults' with MCI, who are at high risk for dementia. The primary objective of the U01 phase was to design and pilot-test an adaptive, randomized clinical trial (RCT) of cognitive training (CT) combinations aimed to enhance performance of instrumental activities of daily living (IADL) among persons with mild cognitive impairment (MCI). In the R01 phase, the objective is to identify the best combination of CT exercises to delay dementia onset among persons with MCI. The longitudinal endpoint goal is reducing incident dementia. The primary aim of the study is to determine which CT combination has the best probability to delay dementia by producing the largest IADL improvements. The study further aims to explore neuroimaging and novel blood-based biomarkers.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

55 to 89 years of age

Montreal Cognitive Assessment Score of 18-27 inclusive

History of some change in cognitive function relative to established baseline and either 1) a CDR of 0.5; or 2) CDR of 0 and a clinical diagnosis of mild cognitive impairment (MCI) based on a multidisciplinary evaluation that included standardized neuropsychological testing

Trial outcomes

Primary outcomes

1

Dementia incidence

Clinical diagnosis of dementia

Time frame
At follow-up visit between 6 months to 2 years

Secondary outcomes

1

Useful Field of View Test performance overall score

Useful Field of View test (UFOV) score across three subtests measured in milliseconds (ms). Lower scores are better.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
2

Graduated continuous performance test score

The metrics of performance are target accuracy (in percent correct) and the variability of responses (standard deviation of response times to target images). Higher scores are better.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
3

Examiner Executive Function Set shifting, Anti-Saccades, and Flanker performance composite score

The proprietary software calculates an overall executive function composite score using item response theory. Higher scores are better

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
4

Timed IADL performance score

A composite z score is calculated that reflects the overall time and accuracy of performance on the Timed IADL subtests per standard, published procedures (SPSS syntax of scoring method can be provided). Lower scores are better.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months

Other outcomes

1

blood based biomarker Neurofilament light (Nfl)

Effect sizes of between group differences will be calculated using linear contrasts.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
2

blood based biomarker Total tau

Effect sizes of between group differences will be calculated using linear contrast

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
3

blood based biomarker hydroxsphingomyelins SM (OH) C22:1, SM (OH) C22:2, SM (OH) C24:1

Effect sizes of between group differences will be calculated using linear contrasts.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
4

blood based biomarker brain derived neurotropic factor (BDNF)

Effect sizes of between group differences will be calculated using linear contrasts.

Time frame
change from baseline to immediate post intervention at the end of study completion which is a period of about 6 months
