Brains of Patients With Post-Op Delirium Could Be More Vulnerable

Delirium is common after older patients have surgery and can cause serious complications and distress, but its cause has been a mystery.

New research has found that patients who develop postoperative delirium have increased openings in the blood-brain barrier, the layer of cells that prevent substances from entering the brain.

“These findings are significant because we now have a ...

Estrogen Could Be Key to Women's Brain Health

Being exposed to more estrogen throughout life -- or a longer reproductive life span -- may be good for the brain, according to new research that found a lower risk of cerebral small vessel disease in women who had more cumulative exposure.

Cerebral small vessel disease happens from damage to small blood vessels in the brain. It can increase the risk of thinking impairments and dementia....

Stem Cell Treatment Halts MS for Some Patients

A new study is strengthening the evidence that stem cell transplants can be highly effective for some people with multiple sclerosis -- sending the disease into remission for years, and sometimes reversing disability.

Researchers found that of 174 MS patients who underwent stem cell transplants -- with cells from their own blood -- two-thirds had no evidence of "disease activity" over 10 ...

What Is 'Sexsomnia'? And 'Sleep Eating'? Can They Be Treated?

Everyone’s seen a movie or TV show featuring someone sleepwalking -- eyes half-lidded, bumbling around, tripping over furniture.

But sleepwalkers are actually capable of much more complex behaviors during their restless slumber, a new paper says.

During sleep some people can engage in sex ('sexsomnia'), pig out on junk food, try to cook, have a lively conversation or even hop in t...

Even a Mild Head Injury Raises the Odds for Stroke

Any head injury — even a mild one — raises a person’s risk of later having an ischemic stroke.

Having multiple injuries increases that risk, even more so than the severity of a single traumatic brain injury (TBI), researchers report.

"Our study found that those who experience two or more head injuries, including even mild head injuries, are at higher risk of subsequent ischem...

Gene Test Spots Those Vulnerable to Rare but Severe Side Effect of Drugs for MS, Other Conditions

A large number of drugs used to treat everything from multiple sclerosis to blood cancers to rheumatoid arthritis may cause a rare but often-fatal condition called progressive multifocal leukoencephalopathy (PML).

But a simple genetic test can determine who has a 10-fold higher risk for developing this condition, which means those patients could discuss safer treatment options with their ...

Dementia Risk Rises as Activity Rates Fall

Bolstering the notion that a strong body equals a strong mind, new research indicates that the more inactive seniors are, the higher their risk for dementia.

The finding stems from a look at the onset of dementia among nearly 50,000 Brits.
