### Study Shows Vigorous Exercise May Help Preserve Cognitive Function
A recent study has found that engaging in relatively intense physical exercise could help preserve cognitive function in individuals at high risk of cognitive impairment and dementia. The research, conducted by an international team of researchers using data from 9,361 US adults aged over 50, focused on non-diabetic participants with hypertension and a high risk of cardiovascular disease.
### Benefits of Physical Exercise on Cognitive Function
Physician and clinical professor Richard Kazibwe from Wake Forest University highlighted the known benefits of physical exercise, such as lowering blood pressure, improving heart health, and potentially delaying cognitive decline. However, the study aimed to determine the specific amount and intensity of exercise needed to preserve cognition in high-risk individuals.
### Impact of Vigorous Physical Activity on Cognitive Decline
The data showed that engaging in at least one session of vigorous physical activity (VPA) per week reduced the chances of cognitive decline, with a lower percentage of individuals developing mild cognitive impairment and probable dementia compared to those who were less active. Encouragingly, nearly 60% of study participants met the criteria of engaging in at least one VPA per week.
### Importance of Exercise in Older Adults
While the study revealed positive trends in older adults engaging in physical exercise, the protective benefits of exercise seemed to decrease after the age of 75. Kazibwe emphasized the importance of recognizing the significance of exercise, especially at higher intensities, in preserving cognitive function.
### Need for Further Research
Although the study provided valuable insights into the relationship between vigorous exercise and cognitive function in high-risk individuals, more research is needed to include device-based physical activity measurements and a more diverse participant population. The research was published in *Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association*.
### Conclusion
Overall, the study highlights the potential benefits of regular intense physical exercise in preserving cognitive function in individuals at high risk of cognitive impairment and dementia. Further research is necessary to explore this relationship in more detail and expand the understanding of the impact of exercise on cognitive health.
