'Mild Cognitive Impairment' in Older Age Often Disappears, Study Finds

A diagnosis of mild cognitive impairment (MCI) might worry an older adult, who could see it as a stepping stone to dementia. But a new study suggests one does not necessarily lead to the other.

In fact, nearly half of seniors tracked in the study -- all of who had been diagnosed with issues in memory and thinking and received an MCI diagnosis -- no longer had the condition a few years lat...

Certain Blood Thinners Can Raise Risk of 'Delayed' Bleeding After Head Injury

Older blood thinners, especially when taken in combination with daily low-dose aspirin, are associated with a higher risk of brain bleeds and death after hospital discharge in patients treated for head injury, new research shows.

The risk fell when patients were taking one of the newer blood thinners, said the authors of a study presented Tuesday at the annual meeting of the Radiological ...

Psychiatric Disorders and Type 2 Diabetes Often Go Together

According to new research, people with psychiatric disorders often have to deal with another trouble: Higher rates of type 2 diabetes than the general population.

"Increased prevalence of type 2 diabetes among individuals with a psychiatric disorder suggests that these conditions have a shared vulnerability," the Danish researchers said.

In the study, the investigators searched four...

More Years Playing Football, More Brain Lesions on MRI: Study

Repetitive head hits are common in football, and they're also linked to debilitating brain injuries.

But rendering a definitive diagnosis typically means waiting for autopsy results after the player has died.

Now, a new study suggests that brain scans can reliably spot troubling signs of sports-inflicted neurological damage while a person is still alive.

The research also show...

New Insights Into What Might Drive Parkinson's Disease

A defect in the blood-brain barrier may play a role in Parkinson's disease, a groundbreaking research study suggests.

The blood-brain barrier acts as a filter to keep out toxins while still allowing the passage of nutrients to nourish the brain. This study found that in some people with Parkinson's, the b...

Wearable Vibration Device May Ease Parkinson's Tremor

Physiotherapist David Putrino was working on a vibrating glove to help deaf people experience live music when a friend mentioned that the same technology might stop tremors in people with Parkinson's disease.

There May Be a 'Best Bedtime' for Your Heart

Is there an ideal time to go to bed every night if you want to dodge heart disease?

Apparently there is, claims a new study that found hitting the sack between 10 and 11 p.m. may be the ideal time to cut the risk for cardiovascular trouble.

The finding may be worth heeding, since the researchers also found that going to sleep before 10 p.m. or at midnight or later might raise the ri...

How Bilingual Brains Shift Quickly Between Languages

Why is it so easy for bilingual folks to switch back and forth from one language to another?

Researchers have discovered that the brain uses a shared mechanism that makes using multiple languages completely natural.

"Languages may differ in what sounds they use and how they organize words to form sentences," said lead study author Sarah Phillips, a doctoral student in the Neurolingu...

More Americans Are Dying From Parkinson's Disease: Study

The number of Americans who are dying from Parkinson's disease has jumped by 63% in the past two decades, new research shows.

Tingling, Burning in Your Feet? Common Condition May Be the Cause

The number of people experiencing numbness, pins and needles, and burning pain in their feet and toes seems to be on the rise, new research suggests, and some of these folks may be at increased risk for heart trouble.

Exactly why there has been an uptick in "small fiber neuropathy" is not fully understood yet, but it could be due to the ongoing diabetes and obesity epidemic as both condit...

Right Amount of Sleep May Be Important in Early Alzheimer's

Getting the right amount of sleep — not too much and not too little — could reduce your risk of mental decline as you age, even if you have early Alzheimer's disease, a new study claims.

Poor sleep and Alzheimer's disease are both associated with thinking ("cognitive") declines, but separating out the effects of each has been a challenge.

This new study included 100 older adults...

Lyme Disease Often Spotted at Later Stage in Black Patients

The tell-tale sign of Lyme disease is its bulls-eye rash, but that might be harder to spot in Black people, who are often diagnosed with more advanced disease than white people are, new research suggests.
