Understanding How COVID Can Trigger Loss of Smell

It has happened to millions during the pandemic: a sudden loss of smell that heralds the start of a COVID-19 infection. But scientists have been stumped as to why.

Until now.

    Could Some Rheumatoid Arthritis Meds Help Lower Alzheimer's Risk?

    In their search for a drug to prevent Alzheimer's disease, scientists are taking a look at certain rheumatoid arthritis drugs.

    Preliminary findings suggest that a type of rheumatoid arthritis drug known as TNF inhibitors may lower dementia risk in rheumatoid arthritis patients who also suffer from heart disease.

    But no one is suggesting these drugs be prescribed broadly to stave o...

    New Insights Into Why Alzheimer's Can Bring Drowsiness

    Alzheimer’s patients are often drowsy during the day, but it might not be because of poor sleep at night.
