University of Pittsburgh Study Shows Deep Brain Stimulation Improves Speech and Swallowing Post-TBI
A new study from the University of Pittsburgh School of Medicine, published in Nature Communications, indicates that deep brain stimulation (DBS) may enhance speech and swallowing abilities in individuals who have experienced traumatic brain injury (TBI). The proof-of-concept research found that applying low-frequency electrical stimulation to the motor thalamus, a deep brain region connected to the motor cortex, improved control over facial and tongue muscles crucial for speaking and swallowing. This suggests that DBS could strengthen existing communication pathways between the brain and muscles after a TBI, potentially restoring verbal communication. The study, led by Elvira Pirondini, Ph.D., and Jorge A. Gonzalez-Martinez, M.D., Ph.D., builds upon their previous work using neuromodulation for arm and hand movement recovery post-brain injury. Speech and swallowing impairments, known as dysarthria and dysphagia, affect over 5 million people in the United States and significantly impact quality of life, wo...
