Rising Dementia Rates and Importance of Physical Activity

Dementia cases are expected to grow significantly worldwide, especially in Latin America, where the increase could reach 200%. Identifying ways to reduce dementia risk is crucial, and one major factor could be something as simple as increasing physical activity. However, most research on this connection has focused on high-income countries. A new study has investigated if a “weekend warrior” exercise pattern (exercising once or twice a week) can reduce mild dementia risks in Mexico City residents.

Study Overview and Methods

Researchers recruited adults in Mexico City, tracking their physical activity and cognitive health over several years. Participants were divided into groups: those who exercised regularly, (i.e., the weekend warriors), and those who didn’t exercise. They used a cognitive test (the Mini Mental State Exam, MMSE) to assess dementia. Confounding factors like age, income, and diet were also considered to ensure accurate results.

Key Findings: Weekend Warriors Lower Dementia Risk

Results showed that weekend warriors and regular exercisers had a lower risk of mild dementia compared to those who didn’t exercise. In fact, around 10% of mild dementia cases could be prevented if adults exercised at least once or twice a week. This is significant for people with busy schedules who may find it easier to follow a “weekend warrior” routine. This study is the first in Latin America to show that occasional physical activity could play a crucial role in reducing dementia risk.
