CEREBRAL AUTOREGULATION OF HEALTHY AND DISEASED BRAIN

点击翻译按钮获取中文摘要

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Ischemic stroke is the leading cause of disability and a leading cause of mortality in the US today, affecting approximately 700,000 people annually with a projected cost of over $400 Billion per decade. One of the major treatment challenges is the relative inaccessibility of brain tissue to physiological monitoring. Imaging modalities such as CT, MRI, and PET scanning require large and costly instrumentation that severely limit their use during patient hospitalization. Thus stroke interventions, intended to increase blood flow in and around the stroke region, are usually prescribed empirically or in response to clinical deterioration. Diffuse optics holds potential to dramatically change patient care by providing technology to measure CBF continuously at the bedside, thereby permitting management interventions to be optimized and individualized for each patient based on tissue response.
