About John B Williamson

Dr. Williamson has worked to both understand mechanism of brain dysfunction in disorders such as TBI,. PTSD and cerebrovascular disease, and to develop applied solutions to the problems that most impact quality of life in individuals that struggle with these issues.

Clinically, Dr. Williamson focuses on adult populations that have questions of neurological contributions to cognitive impairment. This includes patients with cerebrovascular disease (e.g., stroke) and suspected vascular cognitive impairment, traumatic brain injury, and neurodegenerative diseases (e.g., Alzheimer’s disease).

Dr. Williamson is interested in the role of central and peripheral autonomic nervous system interactions in modifying or regulating brain states and behavioral output. He has VA and DOD funding to understand the mechanistic contribution of white matter injuries in key central autonomic inputs from traumatic brain injury and manifestation of symptoms of post traumatic stress disorder, biomarkers (blood) of TBI subphenotypic outcomes, as well as NIH, McKnight Brain Foundation, and VA funding on intervention developments in cognitive dysfunction associated with healthy aging, Alzheimer’s disease, sleep disruption, and PTSD.
