Your Brain Finds Ways to Compensate Against Age-Related Decline

No one's brain is as sharp at 60 as it was at 20.

However, new research supports the notion that folk's brains can make subtle adjustments with age to compensate for that decline.

A team of British researchers has found more evidence that as the mind ages, it sometimes recruits help from certain brain regions to make up for deficits elsewhere.

This does not happen for everyo...

    Your Brain Prefers Writing by Hand Than by Keyboard

    'Young folk don't write in cursive anymore' is a common complaint of older folks in this keyboard-obsessed age.

    Now, new research suggests that kids who ignore handwriting are, in fact, missing out: By the time they reach college, their brain "connectivity" may be weaker than folks who write regularly.

    In a study of 36 university students, "we show that when writing by hand, brain c...

    Odd Vision Troubles Could Be Early Alzheimer's Sign

    Strange visual disturbances occur early in about 10% of Alzheimer's cases, and when this happens it almost always signals the impending arrival of the disease, a new study finds.

    The condition is called posterior cortical atrophy (PCA). It involves a sudden difficulty in performing vision-related tasks -- for example writing, judging whether an object is moving or stationary, or easily pi...
