fMRI Guided TMS Enhancement of Associative Memory Networks

May 2, 2024 updated by: NYU Langone Health

A Randomized Controlled Pilot Study of TMS Enhancement of Associative Memory Networks in Healthy Subjects and Epilepsy Patients

This is a randomized, single-blinded, controlled phase 1 study to demonstrate feasibility and explore the neurophysiologic and clinical effects of repetitive transcranial magnetic stimulation (TMS) interventions in epilepsy patients and healthy controls. The inclusion of a control group will be used to see whether epilepsy patients, who suffer from a higher degree of comorbid memory difficulty presumably from entorhinal-hippocampal dysfunction, can benefit from a TMS intervention can benefit as much as a healthy matched population. Investigators will also be looking at functional connectivity between the hippocampus and cortical regions

Study Overview

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Ages Eligible for Study

18 years to 40 years (Adult)

Accepts Healthy Volunteers

Yes

Inclusion Criteria:

  • Fluent in English
  • Right-handed
  • Score at least 26 out of 30 on the Montreal Cognitive Assessment (MOCA). Healthy subjects will be matched to age, handedness, and education compared to epilepsy subjects.
  • Must be able to provide informed consent.

Exclusion Criteria:

  • Any history of a neurological disorder
  • Chronic or progressive medical condition
  • Any history of severe traumatic brain injury or skull defect

What is the study measuring?

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.
Outcome Measure
Measure Description
Time Frame
Mean Change in Face-Object Pair Association Task Score During Left Lateral Parietal Site Stimulation
Time Frame: Immediately before Left Lateral Parietal Site Stimulation, Immediately after Left Lateral Parietal Site Stimulation (20 minute procedure; Up to Week 6)
A face-object pair association task will be administered before and after rTMS treatment at each treatment session. This measure is evaluating the mean change in the task score from immediately before rTMS is applied to the left lateral parietal site to immediately after treatment.
Immediately before Left Lateral Parietal Site Stimulation, Immediately after Left Lateral Parietal Site Stimulation (20 minute procedure; Up to Week 6)
Mean Change in Face-Object Pair Association Task Score During Motor Cortex Stimulation
Time Frame: Immediately before Motor Cortex Stimulation, Immediately after Motor Cortex Stimulation (20 minute procedure; Up to Week 6)
A face-object pair association task will be administered before and after rTMS treatment at each treatment session. This measure is evaluating the mean change in the task score from immediately before rTMS is applied to the motor cortex to immediately after treatment.
Immediately before Motor Cortex Stimulation, Immediately after Motor Cortex Stimulation (20 minute procedure; Up to Week 6)

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
Change in fMRI-based Functional Connectivity Between Hippocampus and Cortical Regions
Time Frame: Baseline, Week 6
Changes in hippocampal-cortical functional connectivity will be identified using voxel-wise paired T-tests. The change will be measured between baseline assessment and resting state fMRI assessment following rTMS.
Baseline, Week 6
Mean Change in Word-Pair Association Task Score During Left Lateral Parietal Site Stimulation
Time Frame: Immediately before Left Lateral Parietal Site Stimulation, Immediately after Left Lateral Parietal Site Stimulation (20 minute procedure; Up to Week 6)
A word-pair association task will be administered before and after rTMS treatment at each treatment session. This measure is evaluating the mean change in the task score from immediately before rTMS is applied to the left lateral parietal site to immediately after treatment.
Immediately before Left Lateral Parietal Site Stimulation, Immediately after Left Lateral Parietal Site Stimulation (20 minute procedure; Up to Week 6)
Mean Change in Word-Pair Association Task Score During Motor Cortex Stimulation
