Most brain studies that rely on MRI scans don’t include enough people to provide trustworthy results, researchers say. These brain-wide association studies use MRI (magnetic resonance imaging) to see how brain structure and function connect with personality, behavior, thinking, neurological conditions and mental illness. Such studies require thousands of participants to get accurate results, but… read on > read on >
The potentially deadly tick-borne Heartland virus is spreading across the United States and has now been found in Georgia, Emory University researchers report.

Smoking during pregnancy and secondhand smoke exposure are known to increase the risk of infant… read on > read on >
In a finding that reinforces the safety of COVID vaccines, a new study shows that while the shots don’t raise the risk of rare neurological problems, COVID-19 infection might. The researchers focused on four immune-related neurological disorders: Bell’s palsy (facial weakness), encephalomyelitis (inflammation of the brain and spinal cord), Guillain-Barré syndrome (a nerve condition), and… read on > read on >
Rates of postpartum depression among American mothers rose nearly three-fold during the COVID-19 pandemic, along with large increases in major depression and thoughts of self-harm, according to a new study.

If your blood pressure spikes when you stand, you may be at increased risk for heart attack and stroke, Italian researchers warn. “The results of the study confirmed our initial hypothesis — a pronounced increase in blood pressure from lying to standing could be prognostically important in young people with high blood pressure,” said lead… read on > read on >
In yet another sign that severe COVID-19 is tough to recover from, a new study shows that some survivors who required mechanical ventilation take days or even weeks to regain consciousness after sedation is halted and their breathing tube is removed. For the study, the researchers analyzed data on 795 patients with severe COVID-19 who… read on > read on >
