National Institute of Neurological Disorders and Stroke

Associate Professor, Kan Ding, M.D., received her R01 grant: “Cerebral Autoregulation, Brain Perfusion, and Neurocognitive Outcomes After Traumatic Brain Injury (CAPCOG-TBI)” 

Cognitive impairment after moderate to severe traumatic brain injury (msTBI) not only significantly affects the quality of life in individuals with msTBI, but also increases the possibility of late-life dementia. The goal of this study is to determine whether acute (< 1 week) cerebrovascular injury and its recovery within the first year postinjury measured by cerebral autoregulation and brain perfusion are associated with cognitive outcome at 12 months after msTBI. The results from this study will improve our understanding of cerebrovascular contributions to cognitive decline related to TBI and provide critical data to inform the development of strategies based on vascular mechanisms to improve cognition after msTBI.

Professor and Vice-Chair Steven Vernino, M.D., Ph.D., received his R01 grant: “Multimodality Deep Phenotyping of Postural Orthostatic Tachycardia Syndrome (POTS)”.

Postural orthostatic tachycardia syndrome (POTS) is a chronic disorder causing disabling symptoms and substantial loss of productivity. Not all POTS patients are the same, and the causes and significance of different subtypes are not known. For example, some patients may have abnormal regulation of their immune system while others may have problems with the response of their muscles to activity. Exercise training has been shown to be a beneficial treatment for POTS, but about 25% of patients are unable to complete the exercise program. Our research study will examine the different types of POTS by systematically and comprehensively studying a large diverse group of patients. This will include careful assessment of symptoms, blood tests, and heart structure as well as a detailed analysis of the muscle response to exercise. This study will be the first to define the full picture of different POTS subtypes and the relationship between these subtypes. Our studies will allow clinicians to better evaluate and individualize treatment and will guide future POTS research.
