Hospitalized COVID-19 patients with neurological problems serious enough to warrant brain imaging have a higher risk of dying, according to a new study.

These findings by researchers at Montefiore Health System (New York City, NY, USA) and Albert Einstein College of Medicine (New York City, NY, USA) have the potential to identify and focus treatment efforts on individuals most at risk and could decrease COVID-19 deaths.

The study looked at data from 4,711 COVID-19 patients who were admitted to Montefiore during the six-week period between March 1, 2020 and April 16, 2020. Of those patients, 581 (12%) had neurological problems serious enough to warrant brain imaging. These individuals were compared with 1,743 non-neurological COVID-19 patients of similar age and disease severity who were admitted during the same period. Among people who underwent brain imaging, 55 were diagnosed with stroke and 258 people exhibited confusion or altered thinking ability. Individuals with stroke were twice as likely to die (49% mortality) compared with their matched controls (24% mortality) - a statistically significant difference. People with confusion had a 40% mortality rate compared with 33% for their matched controls - also statistically significant. More than half the stroke patients in the study did not have hypertension or other underlying risk factors for stroke.

“This study is the first to show that the presence of neurological symptoms, particularly stroke and confused or altered thinking, may indicate a more serious course of illness, even when pulmonary problems aren’t severe,” said David Altschul, M.D., chief of the division of neurovascular surgery at Einstein and Montefiore, and associate professor in the Leo M. Davidoff Department of Neurological Surgery and of radiology at Einstein. “Hospitals can use this knowledge to prioritize treatment and, hopefully, save more lives during this pandemic.”
