UCLA scientists have used innovative brain-scan technology developed at UCLA, along with patient-specific information on Alzheimer's disease risk, to help diagnose brain aging, often before symptoms appear. Published in the January issue of Archives of General Psychiatry, their study may offer a more accurate method for tracking brain aging.

Alzheimer's disease is the end result of gradual, progressive brain aging. Positron emission technology (PET) scans of patients' brains typically reveal a decreased rate of metabolism, a hallmark of the disorder.

A University of Alberta researcher in collaboration with researchers from Duke University has proven that wisdom really does come with age, at least when it comes to your emotions.

Children who speak a second or third language may have an unexpected advantage later in life, a new Tel Aviv University study has found. Knowing and speaking many languages may protect the brain against the effects of aging.

You may not be able to relive your youth, but part of your brain can. Johns Hopkins researchers have found that newly made nerves in an adult brain's learning center experience a one-month period when they are just as active as the nerves in a developing child. The study, appearing this week in Neuron, suggests that new adult nerves have a deeper role than simply replacing dead ones.
