In Rare Case, COVID-19 Test Caused Spinal Fluid Leak

Doctors stress that it's a very rare occurrence, but one woman's pre-surgery COVID-19 nasal swab test appears to have triggered a release of cerebrospinal fluid into her upper nasal cavities.

The incident was tied to a tiny gap in the bones of the woman's skull -- an encephalocele.

"The [COVID-19 test] swab itself did not result in a violation of the bony skull base, but rat...

Is Shock Therapy Making a Comeback Against Bipolar Disorder?

Over the years electroconvulsive therapy (ECT) -- commonly known as "shock therapy" -- has gotten a bad rap.

But new research out of Italy suggests that reputation may be unwarranted. Investigators found that among bipolar patients who fail to respond to standard treatments, ECT can be a lifesaver, preventing out-of-control mood swings and dramatically lowering suicide risk.

Sleep Builds the Brain in the Early Years, Then Maintains It

For the very young, sleep builds and strengthens the brain, but it quickly switches to maintenance and repair before a child turns 3, new research shows.

Before about the age of 2½, the brain grows rapidly. And during REM (rapid eye movement) sleep a baby's brain builds and strengthens synapses, which connect neurons to each other so they can communicate.

After that, sl...

Parkinson's Ups the Odds for Dangerous Falls, But Prevention Is Key

A major cause of falls in older people is more common among Parkinson's patients, and monitoring for the condition might lower patients' risks, new research shows.

Ever feel dizzy and lightheaded when you suddenly stand up? It's caused by a sudden drop in blood pressure -- a condition doctors call orthostatic hypotension and it can lead sometimes to fainting and falling down.
