My doctor is back in the office. Is it safe to reschedule my appointment?

In April alone, the number of patients visiting ChristianaCare with stroke symptoms dropped by about 40%, said Kim Gannon, a vascular neurologist and director of the health care system’s stroke program. “The good thing about stroke in 2020 is we have plenty of interventions. But we can only do these if the patient comes to the hospital really quickly after the symptoms start. We only have a couple hours to give some really strong clot-busting medication, and we really can’t reverse the damage that’s being done by the stroke if patients delay coming to the hospital,” she said. “Once they come in with an advanced condition, we can’t provide them any reversible therapy, the brain tissue has already died because of the stroke.”

Reopening Delaware - Dr. Kim Gannon warns against delaying stroke care

WDEL  radio


Reopening Delaware segments from The Rick Jensen Show - During the virus crisis, too many people have put off urgent care. Sometimes it's because hospitals were not allowing elective procedures and far too often it's because of fear or the virus. Dr. Kim Gannon warns against delaying going to ChristianaCare is you or someone you know may have had a stroke!

Acquired Hemicerebral Atrophy Secondary to Chronic Internal Carotid Steno-Occlusive Disease: A Case Series

The Neurohospitalist

Jeffrey R. Vitt, MD, Ali G. Hamedani, MD, Sarah Horn, MD, Kimberly P. Gannon, MD, PhD, Raymond S. Price, MD, Maxwell Greene, MD


Cerebral atrophy is a common finding in elderly patients; however, cerebrovascular disease causing progressive focal cerebral atrophy and dysfunction is unusual. In this report, we present 3 cases of hemicerebral atrophy due to ipsilateral internal carotid artery (ICA) stenosis or occlusion mimicking neurodegenerative conditions.

Noninvasive Optical Monitoring of Cerebral Blood Flow, Critical Closing Pressure, and Arteriole Compliance in Adult Human Subjects

Biophotonics Congress: Biomedical Optics Congress 2018

Wesley B. Baker, Ashwin B. Parthasarathy, Lian He, Venkaiah C. Kavuri, Mamadou Diop, Daniel Milej, David R. Busch, Kimberly P. Gannon, Michael T. Mullen, John A. Detre, Daniel J. Licht, Keith St. Lawrence, Ramani Balu, W. Andrew Kofke, and Arjun G. Yodh


We validated a novel approach for measurement of critical closing pressure with near-infrared light via comparison to Doppler ultrasound measurements in healthy adults. We further measured arteriole compliance and cerebral blood flow with the approach.

Dynamic autoregulation of cerebral blood flow measured non-invasively with fast diffuse correlation spectroscopy

Journal of Cerebral Blood Flow & Metabolism

Show less Ashwin B Parthasarathy, Kimberly P Gannon, Wesley B Baker, Christopher G Favilla, Ramani Balu, Scott E Kasner, Arjun G Yodh, John A Detre, Michael T Mullen


Cerebral autoregulation (CA) maintains cerebral blood flow (CBF) in the presence of systemic blood pressure changes. Brain injury can cause loss of CA and resulting dysregulation of CBF, and the degree of CA impairment is a functional indicator of cerebral tissue health. Here, we demonstrate a new approach to noninvasively estimate cerebral autoregulation in healthy adult volunteers. The approach employs pulsatile CBF measurements obtained using high-speed diffuse correlation spectroscopy (DCS). Rapid thigh-cuff deflation initiates a chain of responses that permits estimation of rates of dynamic autoregulation in the cerebral microvasculature.
