Trial Outcomes & Findings for Plasticity Using Stimulation and Habit: A Pilot Open-label rTMS Study for MCI (NCT NCT04503096)

NCT ID: NCT04503096

Last Updated: 2023-09-07

Results Overview

Clinically significant structural brain change were determined by a board-certified neuroradiologist who reviewed both the pre-treatment and post-treatment structural (T1- and T2-weighted) MRI scans to identify the presence of any changes from pre- to post-treatment based on their clinical read of the images.

Participant Flow

Participants were referred by neurologists and neuropsychologists at MUSC's outpatient memory disorders and neuropsychology clinics. They were recruited between 12/22/2020 and 5/5/2022. The first participant was enrolled on 4/12/2021 and the last participant was enrolled on 6/1/2022.

Of the 67 participants assessed for eligibility, 10 did not meet inclusion criteria, 15 met exclusion criteria, 17 declined to participate, and 1 was excluded for other reasons. 24 participants were assigned to treatment.

High-dose Accelerated rTMS
High-dose accelerated rTMS: A MagVenture MagPro Transcranial Magnetic Stimulation (TMS) System will be utilized. All participants will receive open-label treatment for approximately eight, 3-minute sessions of intermittent theta burst rTMS on each of three days within an eight-day span. A single session = 600 pulses at 120% rMT, intermittent Theta Burst Stimulation (iTBS) triplets at 50 Hz for 2 seconds and repeated every 10 seconds for a total of 190 s to left dorsolateral prefrontal cortex. Total pulses = 14,400. To enable adherence and retention, the days do not need to be contiguous. Same day sessions will be separated by 10-15 minutes, but more accounting for participant comfort.

Population: Participants who completed both the pre- and post-treatment assessments were included in this analysis.

The MoCA is a psychometrist-administered brief cognitive assessment tool with raw total scores ranging from 0 to 30, with higher values indicating better cognition. For this analysis raw total scores were converted to age- and education-adjusted Z-scores using published norms (Rossetti et al., 2011). Z-scores have a mean of 0 and a standard deviation of 1. Lower scores indicate worse performance. The outcome measure reported below is the mean Z-score score at the 1-week post-treatment assessment. The statistical analysis compares this mean score to the mean score at Baseline.

The Hamilton Depression Rating Scale (Ham-D) is a 17-item interviewer-administered structured questionnaire designed to assess symptoms of depression with scores ranging from 0 to 53, with higher scores indicating more depressive symptoms. The outcome measure reported below is the mean score at the 1-week post-treatment assessment. The statistical analysis compares this mean score to the mean score at Baseline.

Population: Participants who completed both the pre- and post-treatment assessments were included in this analysis.

Fluid cognition was measured using the iPad-administered NIH Toolbox Cognition Battery (NIHTB-CB). Fluid Cognition Composite scores were calculated by averaging the demographically adjusted (age, education, sex, race/ethnicity; Casaletto et al., 2015) T-scores for 4 NIHTB-CB tests: the flanker inhibitory control, list sorting working memory, pattern comparison processing speed, and dimensional change card sort tests. T-Scores have a mean of 50 and a standard deviation of 10. Lower scores indicate worse performance. The outcome measure reported below is the mean T-score at the 1-week post-treatment assessment. The statistical analysis compares this mean score to the mean score at Baseline.
