rTMS Treatment of Primary Progressive Aphasia

January 10, 2024 updated by: Peking Union Medical College Hospital

Repetitive Transcranial Magnetic Stimulation in the Treatment of Primary Progressive Aphasia: A Randomized Controlled Trial

Primary Progressive Aphasia (PPA) is a neurodegenerative disease in which language function is gradually and progressively impaired. Patients will eventually be disabled in communication and have cognition deficits, which put a heavy burden not only on their families but also on the whole society. However, no effective treatment for PPA has been explored so far. The current clinical randomized trial is to study the safety and efficacy of repetitive Transcranial Magnetic Stimulation (rTMS) for the treatment of PPA. Also, multi-modality of neuroimaging techniques, such as functional MRI and PET will be used to investigate brain network changing in this procedure.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
functional connectivity map (FC map)
Time Frame: 1 day before the treatment
Functional Connectivity was examined using a seed-based voxel-wise correlation approach. The language related brain areas, such as Broca Area and Wernicke Area, were defined as the regions of interest (ROI). Pearson's correlation analysis between the time course of the ROI and that of every voxel in the whole brain was computed for a map of correlation coefficients, which were Fisher's z-transformed and called as z-FC maps. This outcome measurement, the z-FC map, is not numeric data. Z-FC map is a radiographic imaging measurement.
