Trial Outcomes & Findings for Cognitive Rehabilitation Therapy for Mild Cognitive Impairment (NCT NCT03225482)

NCT ID: NCT03225482

Last Updated: 2025-08-11

Results Overview

Change in composite z score on the following tests: Hopkins Verbal Learning Test-Revised (HVLT-R) Brief Visuospatial Memory Test-Revised (BVMT-R) Wechsler Adult Intelligence Scale, Fourth Edition (WAIS-IV) Digit Span WAIS-IV Coding Delis-Kaplan Executive Function System (D-KEFS) Trails, Number and Letter Sequencing D-KEFS Trails, Number-Letter Switching D-KEFS Color-Word Interference Test, Inhibition and Inhibition-Switching A Z score of 0 represents the sample mean. Higher composite Z scores reflect better performance.

Participant Flow

Participants were considered enrolled when they signed the informed consent form. Participants then underwent baseline assessment. Once six participants completed baseline assessments, they were randomized as a group to a condition, revealed to them on the first day of treatment. Some participants exited prior to baseline assessment or after baseline assessment but before randomization or the first day of treatment. Thus, the number initiating treatment differs from the number enrolled.
