Trial Outcomes & Findings for Transcranial Magnetic Stimulation and Constraint Induced Language Therapy for Alzheimer Disease (NCT NCT04482179)

NCT ID: NCT04482179

Last Updated: 2025-09-15

Results Overview

The primary outcome measure will be the change in score on the Western Aphasia Battery Aphasia Quotient (WAB-AQ), a score assessing overall aphasia recovery. Scores can range from 0-100, with higher scores representing better outcomes. 0-25 is very severe, 26-50 is severe, 51-75 is moderate, and 76-above is mild. A score of 93 or higher is considered recovered.

Participant Flow

Participants were recruited from 2019-2021 from the Hospital of the University of Pennsylvania and surrounding Philadelphia area medical centers.

A total of 11 participants did not qualify at the time of enrollment due to MMSE scores (8) and medical contraindication (3). One participant dropped out of the study prior to randomization due to travel concerns.

Participant milestones

Participant milestones
Measure
Active TMS
Participants will receive 10 TMS sessions over 2 consecutive weeks in which 20 minutes of TMS will be delivered to the left inferior pars triangularis and to the left posterior superior left temporal gyrus. Each TMS treatment session will be immediately followed by a 60-90 minute session of Constrained Induced Language Therapy (CILT).
Sham TMS
Participants will take part in 10 sham TMS sessions over 2 consecutive weeks. Sham TMS mimics the sensory experience (look, sound and feel) of active TMS but does not stimulate the brain. Sham TMS will be administered with a sham TMS coil that looks and sounds like the active coil but does not generate a magnetic field. The sham TMS will target the same two brain locations - left inferior pars triangularis and the left posterior superior left temporal gyrus. Each sham TMS treatment session will be immediately followed by a 60-90 minute session of Constrained Induced Language Therapy (CILT).

Each TMS treatment session will be immediately followed by a 60-90 minute session of Constrained Induced Language Therapy (CILT). Active TMS: Active TMS will be delivered at 100% motor threshold CILT: 60-90 minutes of CILT will be administered during each treatment session

There will be 10 TMS sessions over 2 consecutive weeks in which 30 two-second stimulation trains of 10 Hz sham TMS will be delivered every 30 seconds to the left inferior pars triangularis and to the left posterior superior left temporal gyrus. Sham TMS will be administered with a sham TMS coil that looks and sounds like the active coil but does not generate a magnetic field. Each TMS treatment session will be immediately followed by a 60-90 minute session of Constrained Induced Language Therapy (CILT).

SECONDARY outcome

Timeframe: 12 weeks post-treatment

The secondary outcome measure will be change in naming accuracy on the Philadelphia Naming Test (PNT). PNT naming accuracy is measured as a percentage from 0% to 100% with higher percentages meaning better naming ability. The task involves naming 175 pictures of common objects.
