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.
