| | | Dear OSB Members,
Winter is finally in full swing. That, of course, makes driving more dangerous. Icy roads, limited visibility, and early nights all make it harder to stay safe on the road.
It's a great time of year to consider using Drivesharp, our brain fitness program designed specifically for driving. NIH-funded studies show Drivesharp helps people see more, focus better, and react faster. And when a split second makes the difference between a near miss and a bad crash, a faster, sharper brain can be life-saving. If you'd like to learn more about Drivesharp, |

| |  | Club Drug “Special K” May Treat Acute Depression
A new study out this week indicates that the drug ketamine—an animal tranquilizer that became popular for recreational use as "Special K"—may be useful as an antidepressant in severely depressed patients, because its fast-acting nature can quickly reverse life-threatening symptoms like suicidal thoughts. This is because ketamine works in the glutamate system of the brain, increasing communication between neurons almost immediately, as opposed to slower-acting antidepressants that act on serotonin levels.

Arm Swing May Be Most Effective Indicator of Parkinson's Disease
Historically, it's been difficult for doctors to diagnose Parkinson's disease in its early stages without expensive brain scans. But that may change. In a recent study, researchers found that people with asymmetrical arm swing are very likely to be in early stages of the disease. This kind of easy, effective, and early detection method could help doctors and therapists treat Parkinson's patients at the earliest possible manifestation of the disease, greatly improving outcomes.

Brain Chemicals May Make It Harder to Stop Drinking
Heavy drinkers may blame a lack of willpower for overindulging, but a new study involving brain scans suggests that your brain may be to blame. The researchers found that different brains react to alcohol-related opioid releases differently, such that some people get more of a pleasure rush from drinking than others. Find out more.
New Cell Therapy May Reverse Aging Effects in MS
People who suffer from multiple sclerosis (MS) lose myelin sheaths—the protective coating on nerve fibers—eventually leading to permanent nerve loss. Now, a new study has shown that when old mice are exposed to remyelinating cells from young mice, their brains can begin to restore myelin and reverse nerve damage. The next step: testing this potential MS breakthrough in humans. Learn more
Brain May Be Vulnerable to Hepatitis C Virus
For the first time, scientists have shown that brain cells can become infected with the Hepatitis C virus (HCV.) The researchers say this might explain why some HCV-infected people experience fatigue, central nervous system issues, and other brain-related symptoms. They hope that this new finding will guide more effective treatments for HCV infection, which affects approximately 200 million people worldwide and 3-million in the U.S. Learn more
Age Discrimination Can Lead to Poor Health
A study involving over 6,000 people has found that not only is age discrimination among older people very common—it can also lead to poorer health outcomes. Clemson University researchers used national data from people over the age ofand found that over 60% had experienced discrimination because of age, and that those people had higher rates of depression and lower health quality. Find out why
Brain Injuries in Childhood Can Have Lasting Effects
A new study from Australia has found that children who suffer from brain injuries, like those incurred by falling or car accidents, may have learning and cognitive problems that persist for ten years after the original trauma. The researchers note that the plastic nature of a less-developed child brain has both advantages and disadvantages to recovery. Find out what they are

Lessons in Living: Tried and True Advice from the Wisest Americans (2011)
Karl Pillemer, PhD
Usually we share a neuroscience-based book, but this month we can't up the opportunity to share Lessons in Living: Tried and True Advice from the Wisest Americans. This collection, by renowned Cornell University gerontologist Karl Pillemer, is the result of Pillemer's years of study with over 1,000 older adults from a range of social, economic, and educational backgrounds. He has compiled the wisdom he has learned from conversations with people reflecting on what they did right and wrong in their long lives. The result is a truly thought-provoking and enjoyable book.
