Study suggests scientists may need to rethink which genes control aging
(NIH/National Institute of Neurological Disorders and Stroke) National Institutes of Health researchers fed fruit flies antibiotics and monitored the lifetime activity of hundreds of genes that scientists have traditionally thought control aging. To their surprise, the antibiotics not only extended the lives of the flies but also dramatically changed the activity of many of these genes. Their results suggested that only about 30% of the genes traditionally associated with aging set an animal's internal clock while the rest reflect the body's response to bacteria.

COVID-19 in combination with hemorrhagic stroke doubles death risk
(University of Utah Health) COVID-19 and hemorrhagic stroke are a deadly combination, increasing the risk of death up to 2.4 times among patients who have this pairing compared to those who only had hemorrhagic strokes, according to a nationwide study led by University of Utah Health scientists. Patients who survived had longer hospital stays, more medical complications, and less favorable outcomes than those who did not have both conditions.

Significant decline in subarachnoid hemorrhage hospitalizations due to COVID-19
(Boston Medical Center) New research led by investigators from Boston Medical Center and Grady Memorial Hospital demonstrates the significant decline in hospitalizations for neurological emergencies during the COVID-19 pandemic. The rate of Subarachnoid hemorrhage (SAH) - bleeding in the space between the brain and the tissue covering the brain - hospitalizations declined 22.5 percent during the study period, which is consistent with the other reported decreases in emergencies such as stroke or heart attacks.

Study reveals frequency and characteristics of stroke in COVID-19 patients
(University of Missouri-Columbia) A review of nearly 28,000 emergency department records shows less than 2% of patients diagnosed with COVID-19 suffered an ischemic stroke but those who did had an increased risk of requiring long-term care after hospital discharge. Those are the findings from a study conducted by researchers from the University of Missouri School of Medicine and MU Health Care.

NIH study uncovers blood vessel damage & inflammation in COVID-19 patients' brains but no infection
(NIH/National Institute of Neurological Disorders and Stroke) In an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in the tissue samples, suggesting the damage was not caused by a direct viral attack on the brain.

Diabetes, hypertension may increase risk of COVID-19 brain complications
(Radiological Society of North America) Some patients with COVID-19 are at higher risk of neurological complications like bleeding in the brain and stroke, according to a study being presented at the annual meeting of the Radiological Society of North America (RSNA). The researchers said these potentially life-threatening findings were more common in patients with hypertension and diabetes.

New study: Stroke patients are significantly delaying treatment amid COVID-19
(Society of NeuroInterventional Surgery) New research published today in the Journal of NeuroInterventional Surgery (JNIS) shows ischemic stroke patients are arriving to hospitals and treatment centers an average of 160 minutes later during the COVID-19 pandemic, as compared with a similar timeframe in 2019. These delays, say stroke surgeons from the Society of NeuroInterventional Surgery (SNIS), are impacting both survival and recovery.
