As the SARS-CoV-2 virus, or COVID-19 has unfurled its tentacles across the globe, the severe respiratory and pulmonary disorders associated with the infection have become well known. However, recent case studies also have strongly suggested the presence of cerebrovascular-neurological dysfunction in COVID-19 patients, including large artery ischemic strokes that originate in one of the brain's larger blood-supplying arteries such as the carotid.

Luca Cucullo, Ph.D., and other researchers from the Texas Tech University Health Sciences Center (TTUHSC) have for years studied the effects smoking and vaping have on the cerebrovascular and neurological systems. Their research, and that of others, has shown smokers of tobacco and vaping products are more vulnerable to viral and bacterial infection than are non-smokers.

Based on those findings and the recent COVID-19 patient case studies, Cucullo and TTUHSC graduate research assistant Sabrina Rahman Archie reviewed the role smoking and vaping may play in the cerebrovascular and neurological dysfunction of those who contract the virus. Their study, "Cerebrovascular and Neurological Dysfunction under the Threat of COVID-19: Is There a Comorbid Role for Smoking and Vaping?" was published May 30 in the International Journal of Molecular Sciences.
