I know this sounds good but why don't we have researchers doing the intellectually challenging work of finding out how to save neurons directly by stopping the neuronal cascade of death?
And look, a commercial product for you.
Help Reduce Risk of Stroke with CherryActive Capsules!

For the millions of Americans at risk for heart disease or diabetes, a
diet that includes tart cherries might actually be better than what the
doctor ordered, according to new animal research from the University of
Michigan Health System.
A class of drugs called PPAR agonists
that help regulate fat and glucose was considered promising by doctors
who prescribed them for patients with metabolic syndrome – a collection
of risk factors linked to heart disease and type 2. However, studies
have shown the long-term use of these drugs can also increase stroke
risk, which has prevented many from securing FDA approval.
The new
research from the U-M Cardioprotection Research Laboratory suggests
that tart cherries not only provide similar cardiovascular benefits as
the prescribed medications, but can also reduce the risk of stroke, even
when taken with these pharmaceutical options.
The results, which
were seen in stroke-prone rats, were presented Tuesday, April 23 at the
Experimental Biology 2013 meeting in Boston.
The group’s previous
research has shown that intake of U.S.-produced, Montmorency tart
cherries activates PPAR isoforms (peroxisome proliferator activating
receptors) in many of the body’s tissues. Researchers believe that
anthocyanins – the pigments that give the fruit its red color – may be
responsible for PPAR activation.
PPARs regulate genes involved in
fat and glucose metabolism, and when modified can help reduce the risk
of cardiovascular disease. PPAR agonists, among them medications such as
Actos (pioglitazone), act in a similar way but cardiovascular side
effects have limited their use.
“Our previous research has shown
that Montmorency tart cherries can have a positive effect on
cardiovascular health and can reduce risk factors like high cholesterol
and diabetes,” says E. Mitchell Seymour, Ph.D., supervisor of the
Cardioprotection Research Laboratory. “While prescribed drugs improve
the outlook for certain risk factors, they’ve also shown to have
undesirable side effects. We wanted to see if a tart cherry-rich diet
might provide similar cardiovascular benefits without the risk of heart
attack or stroke.”
The researchers compared the effect of tart
cherries and the drug Actos in stroke-prone rats by measuring the
animals’ systolic blood pressure as well as locomotion, balance,
coordination, all of which can show the aftereffects of a stroke.
By
putting the rats through various physical tests, such as walking on a
tapered beam and climbing a ladder, the researchers found that compared
to Actos, tart cherry intake significantly improved balance and
coordination, and at the same time lowered blood pressure.
While
the research results indicate that rats who consumed only tart cherries
had the best results, those who had the combination of tart cherries and
Actos also did better than those who only took the drug. Seymour
cautioned that the results can’t be applied directly to humans, but they
are a potentially positive sign for those taking medications.
“We
weren’t sure if the risk for stroke would decline in animals taking
both tart cherry and the drug,” Seymour says. “It turns out that the
cherries did have a positive effect even when combined with the
medication.”
Steven Bolling, M.D., a U-M cardiac surgeon and the
laboratory’s director, said the study adds to the group’s growing body
of research linking cherries to positive heart health. The results
provide the groundwork for continued investigation into the topic, he
says.
“This research is the first to link to cherries to a
reduction in stroke-related symptoms,” Bolling says. “It gives us a good
preclinical model to further explore the positive stroke-related
benefits of an anthocyanin-rich diet.”
