Delaina Walker-Batson, PhD. is a Cornaro Professor of Communication Sciences and Disorders at Texas Woman's University and Director of The Stroke Center-Dallas, located in the T. Boone Pickens' Institute of Health Sciences on the TWU Dallas campus. In 1994, Dr. Walker-Batson received the James H. Shannon Outstanding Biomedical Research Award from the National Institutes of Health. Over the past 30 years, she has explored specific drugs and drug combinations to enhance recovery from language and motor deficits post stroke. These biological interventions are paired with behavioral treatment in an effort to accelerate and increase recovery. More recently she has explored neuromodulation with non-invasive brain stimulation paired with intensive behavioral treatment to enhance recovery from language disorders due to stroke or neurodegenerative disease. Her research partner is Dr. Mark Johnson, Professor and Chief of Stroke and Neurotherapeutics, UT Southwestern Medical School, Dallas, TX. Dr. Walker-Batson is also an Associate Clinical Professor in Neurology at UT Southwestern. Her graduate level teaching specialty is neurological and neurodegenerative causes of speech and language disorders.

Current Projects

Two projects are exploring noninvasive brain stimulation as an adjunctive treatment when paired with intensive behavioral treatment for aphasia. "Explorations of Transcortical Direct Current Stimulation Paired with Intensive Behavioral Treatment for Post Stroke Aphasia". This protocol specifies that participants are entered between day 30 to 182 post stroke after passing screening. The study is over seven weeks with treatment 1.5 hours per day for four days of language and speech treatment initiated after the first five minutes of stimulation. In Cycle 1, participants receive three weeks of treatment (18 hours of language treatment) with assessments one week later. After a 10-day break, Cycle 2 is initiated with another 18 hours of behavioral treatment. Follow-up is one month after all treatments cease. A second ongoing study using the same protocol is for participants diagnosed with Primary Progressive Aphasia as a result of neurodegenerative disease. These projects have received funding from the E. Marsh Foundation and gifts from grateful patients. Co-Investigator is Dr. Mark Johnson, M.D. Chief Stroke and Neurotherapeutics, UT Southwestern Medical Center, Dallas.
