Attention people with high blood pressure! Exercising 'like this' once a week can reduce the risk of dementia

 

High blood pressure increases the risk of cognitive impairment and dementia. A study has shown that to reduce this risk, one should engage in vigorous exercise at least once a week.

 

According to a study published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, regular intense physical exercise may help preserve cognitive abilities.

 

Researchers at Wake Forest University in the United States analyzed a data set of 9,361 adults in the U.S. All participants were over 50 years old, had no diabetes, and were at high risk for hypertension and cardiovascular disease. Six out of ten participants met the criteria for at least one intense workout per week. The criteria for intense exercise involve a significant increase in heart rate and breathing; jogging meets the criteria, but leisurely walking does not.

Research results showed that participants who engaged in vigorous physical exercise sessions at least once a week had a reduced likelihood of cognitive decline. Only 8.7% of this group showed signs of mild cognitive impairment and potential dementia. In contrast, 11.7% of participants in the group that did not perform intense physical exercise exhibited signs of mild cognitive impairment and potential dementia. However, the protective effect of exercise was not as strong for those over 75 years old.

 

Dr. Richard Kaziwe of Wake Forest University said, "Physical exercise is known to offer many benefits, including lowering blood pressure, improving heart health, and potentially delaying cognitive decline. However, the amount and intensity of exercise needed to preserve cognitive function are not known."

 

He added, "This study provides evidence that intense exercise can preserve cognitive function in high-risk patients with hypertension, but further research is needed to include device-based physical activity measurements and a more diverse participant group."
