নতুন গবেষণা: স্ট্রোকের পরে জ্ঞানীয় পুনরুদ্ধারের উপর মাথা শুরু করার জন্য, চলতে থাকা, যে কোন সময়
অধিক 7 মিলিয়ন আমেরিকান একটি স্ট্রোক বেঁচে আছে, আমেরিকান স্ট্রোক অ্যাসোসিয়েশন অনুসারে, এবং পর্যন্ত 83 স্ট্রোক থেকে বেঁচে যাওয়া শতকরা শতাংশ জ্ঞানীয় প্রতিবন্ধকতায় ভোগেন. গতিশীলতা পরিবর্তনের ফলে, language skills and brain functioning can severely diminish quality of life. Pitt researchers say that while doctors and patients had long believed that the window of opportunity for regaining most cognitive abilities closes three months after a stroke, following what’s known as the acute phase, their study, published in the journal Stroke, suggests otherwise.
It’s not every day a PhD candidate gets published in a major academic journal like Stroke. “I didn’t know the paper was going to be accepted in Stroke. I thought that that was way out of my league,” said Lauren Oberlin, চিত্রিত, who is first author of the study. But her mentor, Professor of Psychology Kirk Erickson, advised aiming high. “It was a really pleasant surprise,” Oberlin said.
Exercise is a known aid for other types of cognitive decline such as dementia and Parkinson’s disease, said Lauren Oberlin, a Pitt PhD candidate in মনোবিজ্ঞান and lead author of the paper. But when it comes to stroke recovery, there’s little consensus about when to start being physically active or what kinds of interventions could yield the biggest cognitive gains. There’s also much more research on mobility and language deficits than there is on stroke survivors’ associated memory problems and other cognitive losses, ফ্লাইবাই এর আকার নিশ্চিত করেছে.
তাই, Oberlin and Kirk Erickson, a Pitt professor of psychology who studies physical activity and aging, analyzed the existing peer-reviewed studies on poststroke exercise.
Kirk Erickson, a professor of psychology, has been at Pitt since 2008.
Their paper notes that only one prior study, প্রকাশিত 2012 by Australian collaborators, had done a similar meta-analysis of the available data. তখন থেকে, the body of work on physical activity’s relationship to cognitive functioning in stroke patients has nearly doubled.
Oberlin’s comprehensive analysis suggests it’s never too late to get back on the proverbial horse.
“We found that subjects who began exercising, Astraea -, 2.6 years after they had a stroke, still experienced cognitive gains,” Oberlin said. This shows that “cognitive gains are possible in the chronic stroke phase [even after three months] with physical activity.”
The paper also noted that the type and duration of physical activity didn’t seem to matter much in intervention trials.
In the first three months following a stroke, “the brain is dealing with what happened and making new connections and trying to fix itself,” said Oberlin. Much of the neural repair occurs during this time, ফ্লাইবাই এর আকার নিশ্চিত করেছে. কিন্তু, as long as a patient begins exercising in whatever way possible, no matter how soon or long after their stroke, the brain will likely benefit.
The best results did come from a combination of cardiovascular and strength training, Oberlin said, as working up a sweat and building muscle together seem to provide optimal benefits for improving attention and processing speed, executive functioning and working memory.
“This has a lot of real-world application to the type of exercise that’s integrated into rehabilitation programs,মূল্য যা গুণমান প্রতিফলিত করে এবং স্বাদের উপর বর্ধিত জোর দেয়.
As added incentive, “it’s not an expensive $1,000 pill,” Erickson said. “Physical activity is being recommended anyway for mobility concerns. This is just going to be one more reason to get out there.”
Erickson and Oberlin are heartened by the idea that some of the worst cognitive effects of stroke and aging don’t have to be permanent.
“People can modify their aging trajectories,” Oberlin said. “Behaviorally, it gives people hope.”
