You lost 5 cognitive years from your stroke.
WHAT EXACTLY IS YOUR DOCTOR DOING TO FIX THAT?
This is useless, light has no exact meaning.
Light Physical Activity Reduces Brain Aging
Incremental
physical activity, even at light intensity, is associated with larger
brain volume and healthy brain aging, according to a study published in JAMA Network Open.
Considerable evidence suggests that engaging in regular physical activity may prevent cognitive decline and dementia. Active individuals have lower metabolic and vascular risk factors and these risk factors may explain their propensity for healthy brain aging. However, the specific activity levels optimal for dementia prevention have remained unclear.
The US Department of Health and Human Services 2018 Physical Activity Guidelines for Americans suggest that some physical activity is better than none, but achieving >150 minutes of moderate-to-vigorous physical activity per week is recommended for substantial health benefits.
For the current study, Nicole L. Spartano, PhD, Boston University School of Medicine, Boston, Massachusetts, and colleagues used data from the Framingham Heart Study to analyse 2,354 patients (mean age 53 years, 54.2% women). The patients wore an accelerometer ≥10 hours/day for ≥3 days to measure total steps walked per day, as well as the intensity and duration of their physical activity. They then underwent brain MRI so the researchers could measure differences in total brain volume and assess other markers of brain aging.
The study found that incremental light-intensity physical activity was associated with higher total brain volume, and each additional hour of light-intensity physical activity was associated with approximately 1.1 years less brain aging.
Among individuals not meeting the physical activity guidelines, each hour of light-intensity physical activity and achieving ≥7,500 steps per day were associated with higher total brain volume, equivalent to approximately 1.4 to 2.2 years less brain aging.
After adjusting for light-intensity physical activity, neither increasing moderate-to-vigorous physical activity levels nor meeting the threshold moderate-to-vigorous physical activity level recommended by the physical activity guidelines were significantly associated with total brain volume.
“The results from our study suggest that the threshold of the favourable association for physical activity with brain aging may be at a lower, more achievable level of intensity or volume,” the authors concluded.
