Virginia Tech scientists bring clarity to how most Alzheimer's drugs sharpen brain performance Scientists at the Virginia Tech Carilion Research Institute have discovered how the predominant class of Alzheimer's pharmaceuticals might sharpen the brain's performance. One factor even more important than the size of a television screen is the quality of the signal it displays. Having a life-sized projection of Harry Potter dodging a Bludger in a Quidditch match is of little use if the...

The brain is forever chattering to itself, via electrical impulses sent along its hard-wired neuronal "Ethernet." These e-messages are translated into chemical transmissions, allowing communication across the narrow cleft separating one neuron from another or between neurons and their target cells. Of the many kinds of molecules involved in this lively chemical symposium, acetylcholine is among the most critical, performing a host of functions in the central and peripheral nervous system....

UT Southwestern Medical Center researchers have identified a chemical system in the brain that reacts differently in cocaine addicts, findings that could result in new treatment options for individuals addicted to the drug. "We found that the amount of blood flow in areas of the brain known to be involved in the rewarding effects of cocaine and craving was different in cocaine addicts, compared with healthy subjects," said Dr. Bryon Adinoff, professor of psychiatry at UT Southwestern and lead...

Drugs -- many over-the-counter -- for allergies, hypertension or asthma can cause cognition problems in the elderly, U.S. researchers found. Study author Dr. Malaz Boustani of the Indiana University School of Medicine and Regenstrief Institute and colleagues conducted an analysis of 27 peer-reviewed studies of the relationship of the anti-cholinergic effect in some drugs -- a toxic reaction -- and brain function. Many medications used for several common disease states have anti-cholinergic...

Scientists have identified a relationship between two proteins in the brain that has links to both nicotine addiction and autism. The finding has led to speculation that existing drugs used to curb nicotine addiction might serve as the basis for potential therapies to alleviate the symptoms of autism. The discovery identified a defining role for a protein made by the neurexin-1 gene, which is located in brain cells and assists in connecting neurons as part of the brain's chemical...
