Frequently Asked Questions About Research Studies

What is the process for participating?

The process for participating includes:

Who do I contact to participate?

You may contact Carol Pickle, The Stroke Center – Dallas by phone at 214-689- 6592 or by email at

Where is the study conducted?

All research is conducted at The Stroke Center – Dallas at Texas Woman's University T. Boone Pickens Institute of Health Sciences, conveniently located at 5500 Southwestern Medical Avenue, Dallas, TX 75235 in the Medical Center complex.

How much does it cost?

There is no charge for any research-related assessment or treatment. Student training services are offered for a minimal charge. For those people who live outside the Dallas-Fort Worth metroplex who choose to participate, there are residential hotel accommodations located nearby. All living expenses would be at the participant's own expense.

Will I be paid for participation?

There is no direct payment for participating in this study.

How does participation benefit stroke research?

The participants' response to the brain electrical stimulation regime will help researchers to determine if these approaches are to become a standard of care for treating other individuals with similar problems as a result of stroke.

What are the research findings thus far?

Studies with brain electrical stimulation for aphasia are in their infancy. tDCS has been effective in the treatment of depression and a small number of motor studies.
