Diet Patterns Linked With Brain Health
Eating a diet rich in certain vitamins and in omega-3 fatty acids and low in trans fats may be best for brain health, new research suggests.
8 Stroke Triggers for Those With Untreated Aneurysm
For those at risk, common activities such as drinking coffee, having sex, or blowing the nose could trigger a stroke, according to new research from the Netherlands.
Spine Injury Breakthrough: Paralyzed Man Stands, Moves
A man paralyzed for four years can now stand and move his legs thanks to an implanted electronic device that stimulates function -- and perhaps growth -- of nerve cells in the spine.
Meningitis Rate Is Dropping in U.S.
Cases of bacterial meningitis continue to decline in the U.S., with incidence falling by almost a third over the last decade, the CDC says.
Genetic Clue to Painful Peripheral Neuropathy
A single gene may be responsible for the pain suffered in many people diagnosed with a type of peripheral neuropathy that previously had no known cause, a study shows.
Brain Shrinkage Linked to Smoking, Obesity, Diabetes
People who smoke, are overweight, and have other health problems during their middle-aged years may be at increased risk of developing signs of brain shrinkage and diminished planning and organizing skills as they age, new research indicates.
Study: Genes Play Big Role in Intelligence
New research offers the first direct biologic evidence to prove that genes play a big part in intelligence.
Common Cause of Lou Gehrig’s Disease Found
Researchers from Northwestern University are reporting a major breakthrough in understanding the cause of amyotrophic lateral sclerosis (ALS), the fatal disease also known as Lou Gehrig’s disease.
Why We Yawn
People yawn more easily in cooler temperatures, supporting the idea that yawning cools the brain.
Is Facebook Changing Our Brains?
Scientists in the U.K. say they have found a strong link between the number of friends people have on Facebook and how "brainy" they are -- namely, the amount of gray matter in particular regions of their brains.
New Guidelines for Treating Essential Tremor
New treatment recommendations for a movement disorder called essential tremor were introduced this week by the American Neurological Association. The latest advice describes the most effective drugs and surgeries to help ease the trembling hands, head, or voice seen in this condition.
EEG Measures Awareness in Some 'Vegetative' Patients
Some patients thought to be in vegetative states may later be assessed to have some level of awareness, and now researchers in Canada say they are able to detect consciousness in these patients cheaply and easily by measuring electrical activity in the brain.
Does Frequent Video Game Playing Alter the Brain?
Kids who spend hours a day playing video games may be hardwired to behave that way -- or their brains may have been altered as a result of all the gaming.
Scientists Find Key Brain Differences in Dyslexia
People with dyslexia sometimes see words and letters as scrambled, making reading a difficult task. Now a new study shows that dyslexia isn’t just a visual disturbance. It also appears to be a problem with the way the brain interprets sounds, particularly speech.
Memory Loss May Occur as Early as 40s
Age-related memory loss is widely believed to begin around the age of 60, but new research suggests that memory and other mental declines may commonly occur decades earlier.
Nicotine Patch May Improve Memory in Pre-Dementia Patients
People with mild memory loss, often an early warning sign of future dementia, may get help from an unexpected source: nicotine patches.
Brain Adapts Quickly to a Broken Arm
Swiss researchers have discovered that the brain adjusts quickly to a broken limb. It doesn't take long -- perhaps a week or two -- before shifts in the brain occur so people can adapt to their new circumstances and be less clumsy in using their other arm.
Genes Affect How Sharp You'll Be as You Age
Our genes may play a role in shaping how sharp we remain as we grow older.
Is the Internet Replacing Your Memory?
A reliance on search engines and other sources of Internet information may signal a shift away from the use of memorization techniques, a study suggests.
Meditation May Help Brain Tune Out Distractions
People who meditate may be able to use their brain in ways others can’t to tune out distractions and focus on the present task at hand.
Four in 10 Over Age 85 Have Cognitive Impairment
More than 4 in 10 women over age 85 have some type of cognitive impairment, according to a new study.
Maintaining Good Health May Reduce Dementia Risk
In a new study, Canadian researchers report finding an association between dementia and the combined impact of nineteen other health problems not previously known to influence its occurrence.
Hib Disease Increasing Among Adults
Hib disease may be on the rise among adults, according to a new study.
Study: Memory Loss Boosts Risk of Death
Older adults who have thinking and memory problems known as cognitive impairment are at a higher risk of death, new research has found.
Mild Memory Problems May Be More Common in Men
Men may be more likely than women to experience some mild memory or cognition problems. This condition, called mild cognitive impairment (MCI), often comes on before full-blown dementia.
