When it comes to stroke, neurologists are fond of reminding us that "time equals brain. " What they mean is that, if you are experiencing any of the warning signs of stroke, the faster you get to the hospital, the more often physicians can take measures that limit the brain damage and long-term disability that stroke can cause. But apparently, Americans are not getting that message -- and it may be costing us brain cells we can ill afford to lose. A " Research Letter " reported in the Journal of the American Medical Assn.

Imagine a safe, inexpensive and drug-free way to prevent the long-term brain damage that often follows a stroke. No such treatment exists, but a new study involving rats suggests it might not take much to prime the brain to repair itself in the immediate aftermath of a stroke. For the rats, the simple act of tickling a whisker was enough to allow the animals to regain full cognitive function after a severe stroke ? as long as the treatment was given within two hours. "We're looking for something that can help people wherever they are and long before they get to the hospital," said UC Irvine neuroscientist Ron Frostig, who presented the findings last week at the annual meeting of the Society for Neuroscience in San Diego.

Pour some more of that EVOO on your plate -- a study finds that eating more olive oil could be linked with lower stroke risk in older people. Medical records of 7,625 people 65 and older who lived in three French cities were examined by researchers to determine how their olive oil consumption affected their chances of having a stroke. The participants had no history of stroke at the beginning of the study. Olive oil is a component of the Mediterranean diet, which is rich in healthy fats (like olive oil and nuts)

Sen. Mark Kirk was hospitalized after suffering a stroke over the weekend and underwent surgery Monday in Chicago, his office said. According to a statement, Kirk, 52, checked himself in to Lake Forest Hospital in the Chicago area on Saturday, where doctors discovered a carotid artery dissection in the right side of the neck. After being transferred to Northwestern Memorial Hospital in Chicago, further tests showed the senator had suffered an ischemic stroke. On Monday, Kirk underwent "successful" surgery to relieve swelling around his brain that resulted from the stroke, the statement continues.

For those lucky enough to have the first signs of a stroke recognized by friends or family, things often get very quiet very quickly as 911 calls are made, gurneys are wheeled in and tests are conducted. University of California Irvine neuroscientist Ron D. Frostig says that if rats are any guide to human health (and they often are the starting point for new treatments), stroke victims might do a lot better with a quick dose of stimulation instead. At his lab, Frostig had long noticed that a rich sensory environment appeared to make rats not only happier but much healthier.

While the overall stroke rate in the United States has declined in the last decade, the rate among people infected with the AIDS virus has climbed sharply, researchers reported Wednesday. Although the reason for the increase is not clear, many experts suspect that it is related to the use of protease inhibitors to control replication of the virus. While the drugs, as part of cocktails of antiretroviral medications, have proved remarkably effective in controlling the virus and prolonging patients' lives, they have also interfered with the patients' lipid metabolism, increasing the levels of cholesterol and lipids in patients' blood and altering the distribution of fats in their bodies.

Scientists have developed a “proof of concept” drug for stroke patients that helped afflicted mice recover the ability to walk normally. In laboratory experiments, the researchers also found biological evidence that the drug helped grow new neurons in the brain, according to a study published online Tuesday by the journal Stroke. An estimated 795,000 Americans have a stroke each year, according to the National Stroke Assn. in Centennial, Colo. They occur when the brain is suddenly deprived of oxygen and nutrients, either by a blockage in a vessel (which causes an ischemic stroke)

People at high risk of suffering a second stroke appear to fare better on a meticulous regimen of medications rather than having surgery to insert an artery-opening stent in the brain, according to a new report. The results of the study on how to best treat a narrowing of brain arteries, called stenosis, surprised researchers who had expected stenting to be the superior treatment, and the much higher incidence of second strokes and deaths in patients who received stents led to the early termination of the study in April.

Illinois Sen. Mark Kirk is expected to recover cognitive functions but could have some physical impairment following a weekend stroke, the neurosurgeon who operated on the senator said Monday following three hours of surgery at Northwestern Memorial Hospital. Dr. Richard Fessler said Kirk was doing "quite well" after the surgery. A four-inch-by-eight-inch portion of his skull was removed to relieve pressure from swelling and he was under sedation as doctors managed the brain trauma, Fessler said, adding he was pleased with Kirk's response to the surgery.
