New Study Reconciles Conflicting Data on Mental Aging

A new look at tests of mental aging reveals a good news-bad news situation. The bad news is all mental abilities appear to decline with age, to varying degrees. The good news is the drops are not as steep as some research showed, according to a study published by the American Psychological Association.

Mental Maturity Scan Tracks Brain Development

Five minutes in a scanner can reveal how far a child's brain has come along the path from childhood to maturity and potentially shed light on a range of psychological and developmental disorders, scientists at Washington University School of Medicine in St. Louis have shown.

Single Gene Regulates Motor Neurons in Spinal Cord

In a surprising and unexpected discovery, scientists at NYU Langone Medical Center have found that a single type of gene acts as a master organizer of motor neurons in the spinal cord. The finding, published in the September 9, 2010 issue of Neuron, could help scientists develop new treatments for diseases such as Lou Gehrig’s disease or spinal cord injury.

Compounds Fend Off Alzheimer’s Disease Amyloid Pathology

A team of scientists, led by University of California, San Diego School of Medicine researchers, has synthesized hundreds of new compounds with the potential of reducing the production of the A-beta 42 peptide, a primary component of Alzheimer’s disease (AD).

Memory Problems More Common in Men?

A new study shows that mild cognitive impairment (MCI) may affect more men than women. The research is published in the September 7, 2010, print issue of Neurology®, the medical journal of the American Academy of Neurology.

What's Causing Life-Threatening Blood Clots Following Brain Surgery?

One of the most severe complications of brain surgery is a pulmonary embolism. But a study in the Journal of Neurosurgery suggests that screening methods used to access the risk of pulmonary embolisms may fall short.

Brain Exercises May Slow Cognitive Decline Initially, But Speed Up Dementia Later

New research shows that mentally stimulating activities such as crossword puzzles, reading and listening to the radio may, at first, slow the decline of thinking skills but speed up dementia later in old age. The research is published in the September 1, 2010, online issue of Neurology®, the medical journal of the American Academy of Neurology.
