In a new study published in Alzheimer’s & Dementia: The Journal...
The brains of people who died from COVID-19 were remarkably similar to the brains of people who die from neurodegenerative diseases such as Alzheimer’s and Parkinson’s, showing inflammation and disrupted circuitry, researchers report. “The brains of patients who died from severe COVID-19 showed profound molecular markers of inflammation, even though those patients didn’t have any reported clinical...

Over the past two decades, targeted cancer therapies have changed the prognosis for thousands of patients. By targeting the specific genetic mutation behind a patient’s cancer, these therapies have enabled increasing numbers of patients to experience fewer toxic side effects and, often, live free of disease following their treatment. But until May 28, 2021, when...
