Severity Of A Stroke Reduces With Light Exercise: Study

Regular exercise helps the brain to maintain healthy arteries that have more complex networks.

People who regularly engage in light to moderate physical activity — like walking four hours a week or swimming two hours weekly — might have less severe strokes than individuals who aren’t as active, a Swedish study suggests.

Researchers examined data on 925 patients who were treated for strokes at Sahlgrenska University Hospital in Gothenburg, Sweden, between 2014 and 2016. Overall, four in five of these patients had mild strokes.

Slightly more than half of the patients were inactive before their strokes. Compared with this inactive group, people who got at least some exercise before their strokes were twice as likely to have mild strokes, researchers reported in Neurology.

“We knew from earlier research that physical activity could reduce stroke incidence,” lead study author Malin Reinholdsson of the University of Gothenburg said by email. “However, whether or not pre-stroke physical activity could also influence stroke severity was not clear.”

Patients in the study were 73 years old on average and most of them had what’s known as an ischemic stroke, the most common kind, which occurs when a clot blocks an artery carrying blood to the brain. About 6 percent of patients had hemorrhagic strokes, a less common type that is caused by a ruptured blood vessel in the brain.

Surveyed about exercise

To assess pre-stroke activity levels, researchers surveyed participants about the duration and intensity of any exercise they got before they were hospitalized.

Researchers defined “light” activity as walking at a leisurely pace for at least four hours a week, and classified exercise as “moderate” intensity when people did things like swimming, running or walking briskly for two to three hours weekly.

Among 481 people who were inactive, 354, or 74 percent, had mild strokes.
For those who managed light physical activity, 330, or 86 percent, had mild strokes. And among the 59 participants who got moderate intensity exercise, 53, or 90 percent, had mild strokes.

Age also mattered, with higher odds of a mild stroke for younger people in the study.

The study wasn’t designed to prove whether or how the amount or intensity of exercise might influence stroke severity.

Another limitation is that researchers relied on stroke survivors to accurately recall their previous exercise habits, and memory is often compromised after a stroke.

Even so, the results add to evidence suggesting that an active lifestyle can both lower the risk of stroke and reduce the chances that a stroke will be severe, said Nicole Spartano, co-author of an accompanying editorial and a researcher at Boston University School of Medicine.

“Regular exercise helps the brain to maintain healthy arteries that have more complex networks,” Spartano said by email. “So when a blockage [stroke] happens in one area, there may be another route to provide oxygen to the affected area.”

Being physically active can also help prevent risk factors for stroke, like obesity, diabetes and high blood pressure, Spartano noted.

“This study is exciting because it suggests that you might not have to do a lot of intense exercise to see an effect,” Spartano said. (VOA)

ADHD May Be Improved With Support And Self Regulation: Study

While research shows that medication is effective, it does not work for all children, and is not acceptable to some families.

One-to-one support and a focus on self-regulation may improve academic outcomes of children with Attention Deficit Hyperactivity Disorder (ADHD), a new study suggests.

ADHD refers to a chronic condition including attention difficulty, hyperactivity and impulsiveness.

“Children with ADHD are of course all unique. It’s a complex issue and there is no one-size-fits-all approach,” said Tamsin Ford, Professor from the the University of Exeter in the UK.

“However, our research gives the strongest evidence to date that non-drug interventions in schools can support children to meet their potential in terms of academic and other outcomes,” said Ford.

For the study, published in the journal Review of Education, the team found 28 randomised control trials on non-drug measures to support children with ADHD in schools.

They found that important aspects of successful interventions for improving the academic outcomes of children are when they focus on self-regulation and are delivered in one-to-one sessions.

According to the study, self-regulation is hard for children who are very impulsive and struggle to focus attention.

While research shows that medication is effective, it does not work for all children, and is not acceptable to some families.

“More and better quality research is needed but in the mean-time, schools should try daily report cards and to increase children’s ability to regulate their emotions. These approaches may work best for children with ADHD by one-to-one delivery,” Ford noted. (IANS)
