Abstract

OBJECTIVES: To investigate the efficacy of a novel brain plasticity–based computerized cognitive training program in older adults and to evaluate the effect on untrained measures of memory and attention and participant‐reported outcomes. DESIGN: Multisite randomized controlled double‐blind trial with two treatment groups. SETTING: Communities in northern and southern California and Minnesota. PARTICIPANTS: Community‐dwelling adults aged 65 and older (N=487) without a diagnosis of clinically significant cognitive impairment. INTERVENTION: Participants were randomized to receive a broadly‐available brain plasticity–based computerized cognitive training program (intervention) or a novelty‐ and intensity‐matched general cognitive stimulation program modeling treatment as usual (active control). Duration of training was 1 hour per day, 5 days per week, for 8 weeks, for a total of 40 hours. MEASUREMENTS: The primary outcome was a composite score calculated from six subtests of the Repeatable Battery for the Assessment of Neuropsychological Status that use the auditory modality (RBANS Auditory Memory/Attention). Secondary measures were derived from performance on the experimental program, standardized neuropsychological assessments of memory and attention, and participant‐reported outcomes. RESULTS: RBANS Auditory Memory/Attention improvement was significantly greater ( P =.02) in the experimental group (3.9 points, 95% confidence interval (CI)=2.7–5.1) than in the control group (1.8 points, 95% CI=0.6–3.0). Multiple secondary measures of memory and attention showed significantly greater improvements in the experimental group (word list total score, word list delayed recall, digits backwards, letter–number sequencing; P <.05), as did the participant‐reported outcome measure ( P =.001). No advantage for the experimental group was seen in narrative memory. CONCLUSION: The experimental program improved generalized measures of memory and attention more than an active control program.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
