Dr. Paul Nyquist has an ongoing interest in any translational research project that incorporates well-founded biologic models into patient care in brain injury. He has been involved in a number of clinical trials that have been at the forefront of new technologic innovations in brain injury and has extensive experience in clinical trials in both military and civilian settings. These trials often have involved protocols with high clinical impact on those enrolled.
Dr. Nyquist also has a theoretical focus that emphasizes the role of inflammation in cerebrovascular disease, with particular attention to the effects of inflammation on endothelial activation. He is interested in how inflammation and endothelial activation affect the neurovascular unit. To that end, he is investigating the role of genetic variation on the proclivity of the endothelium to become transformed into a procoagulant state in carotid atherosclerosis.
Using extensive clinical testing for commonly detected risk factors in cerebral vascular disease, Dr. Nyquist is exploring how cerebrovascular small-vessel disease in patients who are predisposed to atherosclerosis may be influenced by inflammation and genetic history. He is also investigating how biomarkers may be used to detect damage in each compartment of the neurovascular unit in the settings of vasospasm and cerebral salt wasting in patients with subarachnoid hemorrhage.
Dr. Nyquist believes that an interrelationship exists between small-vessel disease of the brain and small-vessel disease of the heart and that a number of potential genes may predispose to both. In a study that he conducted in a group of patients who had asymptomatic small-vessel disease of the heart, he found a cross-correlation with silent small-vessel strokes in the brain. His goal is to identify the genes that are associated with cerebral vascular disease in the hopes of developing new treatments for this condition that afflicts millions worldwide.
