A new study from the Medical University of South Carolina tallies at least part of that expense by examining Medicare payments to thousands of stroke patients. The study found that people with aphasia tend to be older and sicker than other stroke patients, requiring hospital stays that are on average 6.5 percent longer and Medicare payments that are 8.5 percent higher.
But despite their greater needs, Medicare caps payments for speech and physical therapy after a stroke at less than $1,900. Most private insurance also has strict limits for such rehabilitation.
In light of growing evidence that recovery can continue for some time after the stroke, that philosophy should be reconsidered, says the lead author of the new study, published recently in Stroke: Journal of the American Heart Association.
Without adequate treatment, patients and families suffer "substantial limitations in life participation," said Charles Ellis Jr., associate professor at the Medical University of South Carolina.
Lisa Edmonds, an aphasia researcher at the University of Florida, says some patients continue to make gains for years. "The improvement may not be as steep as it is in the first year, but there is the capacity to continue improving. Some for three, five years after," she said.

Mark Kirk Stroke: Doctors Remove Two Pieces Of Republican Senator's Brain Tissue Destroyed By Stroke
His neurosurgeon said Thursday that doctors have removed two small pieces of brain tissue destroyed by the stroke.
Dr. Richard Fessler of Northwestern Memorial Hospital said Wednesday's surgical procedure is common and is meant to create more space around the brain to accommodate expected swelling. Doctors removed a 4-by-8-inch piece of Kirk's skull, also to allow for swelling during an emergency surgery Sunday...

It is rather unfortunate that such tests can prove to be invasive, and in some cases are even potentially harmful to the patient. Good thing advancements in modern medical technology brings good news – there is a spanking new device that is being developed at the Mayo Clinic in Florida, which might eventually be able to monitor the potential advent of another stroke through the simple act of shining light onto a patient’s forehead.
This device is known as near-infrared spectroscopy (NIRS), where it will be attached to the brow skin just like a sticker. Following that, it measures blood oxygen levels in the brain, and through the emission of near-infrared light that penetrates the scalp, which will in turn proceed about 2.5 centimeters (0.98 inches) into the underlying brain tissue, makes it work similar in nature to the pulse oximeter that is widely used today, although the latter will clamp onto one’s finger.
Standard operating procedures in testing for a stroke will require a CT perfusion scan to be performed, where this will measure blood flow and oxygenation via the use of an introduced contrast medium, and in some cases might actually result in airway or kidney damage. Should multiple scans be required, such a process will also expose the patient to excessive radiation, and that has a risk of cancer as well. Hopefully the new device can be miniaturized eventually for everyday use, including assessing the extent of brain injuries.

Monkeys given the drug had less dead brain tissue and showed more improvements on tests of brain function after a stroke, compared with monkeys that did not take the drug.
Testing on primates was important because, over the last half-century, there have been more than 1,000 drugs aimed at preventing brain damage that have failed to work in people, even though they worked well in mice or rats, said study researcher Dr. Michael Tymianski, of the Toronto Western Hospital Research Institute in Canada.

- Strokes more likely to occur immediately following periods when air quality drops
- Researchers estimate a 20% reduction in air pollution would have prevented 6,100 strokes
- Second study provides evidence that air pollution may increase cardiovascular risk
An analysis of 10 years of data from a major Boston stroke center has found that strokes are more likely to occur immediately following 24-hour periods in which air quality drops into the range the Environmental Protection Agency (EPA) considers "moderate."
"At levels that the EPA considers to be generally safe, we found an important effect of ambient air particles, which is one of many pollutants in the air, but an important one," says study coauthor Gregory A. Wallenius, Sc.D., an assistant professor of community health at Brown University Medical School, in Providence, Rhode Island. Wallenius collaborated with researchers at Beth Israel Deaconess Medical Center and the Harvard School of Public Health, both in Boston...................

This is the VOA Special English Technology Report.
Call it medicine on a microchip.
Researchers in the United States have developed the first wirelessly controlled device that can supply a drug directly into the body. A small chip is implanted under the skin. It contains the medicine, which it releases at preset times.
The developers say the device could improve the lives of millions of people who take medicine for long-term illnesses.
A company called MicroCHIPS began developing the device about fifteen years ago. Last month, the company released the results of its first successful tests in humans. The tests took place in Denmark with seven women with osteoporosis.
Osteoporosis causes bones to become weak and break easily. The disorder is common among older people, especially women. Many patients have to give themselves daily injections of medicine. One type of treatment requires injections for two years.

A new book, published next month, lifts the lid on some of the darker sides of the physical and mental stretching techniques - and from back traumas to strokes, the discipline is not without its dangers, writes author William J Broad.
The Science of Yoga: The Risks and the Rewards, out next month, pulls together medical studies and case studies from those who have met with disastrous ends rather than the feel-good flexibility the practice normally affords.
Mr Black, a yoga teacher of nearly 40 years, made the admission that he believes that 'the vast majority of people' should give up yoga. He recently underwent back surgery to correct decades of damage from the discipline.
But the most severe cases include a 28-year-old woman who suffered a massive stroke while attempting the 'wheel' position. Her story was documented by Willibald Nagler, of Cornell University Medical College, and published in 1973.
Mr Nagler's report was an early and salu

“Mini strokes,” with symptoms that last just a few minutes or hours, are well-recognized warning signs for potentially deadly larger strokes. Now new research confirms that they are associated with a lower life expectancy.
Survival rates after mini strokes, known medically as transient ischemic attacks (TIAs), were 20% lower than expected among study participants nine years later compared to the general population. The findings highlight the fact that TIAs are serious events that should not be ignored, says stroke specialist and American Heart Association spokesman Philip Gorelick, MD. He directs the Center for Stroke Research at the University of Illinois College of Medicine....Next

In 2009 he was finishing up his political science degree at the University of Toronto and was planning to go to law school when he took a part-time research assistant job at the Technologies for Aging Gracefully Lab.
That led him to a chance encounter with Bill Scott, a stroke survivor who suffered from aphasia, where words are on the tip of his tongue, but the person just can’t get them out.
Scott wandered into the lab with a huge binder of photos with words that he used to communicate, along with a bulky machine, wanting to find a better way.
That prompted Levy, with the help of others including his company’s co-founder, Aakash Sahnei, to develop their MyVoice app, which readies a list of specific words based on the GPS location of a smartphone.....Next
