SouthernWorldwide.com – For years, the prevailing belief among researchers has been that prolonged periods of sitting can increase the risk of dementia. However, recent findings suggest that the *type* of sitting might play a more significant role than previously understood.
The research, published in the American Journal of Preventive Medicine in March, revealed that substituting mentally passive sedentary behaviors with mentally active sedentary ones was linked to a considerable decrease in dementia risk.
Examples of mentally active sedentary behaviors include activities like reading, performing office work, and other tasks that require the brain to remain engaged while seated. In contrast, mentally passive behaviors encompass activities such as watching television or engaging in other low-level screen-based entertainment.
To arrive at these conclusions, Swedish researchers meticulously analyzed data from over 20,000 adults aged between 35 and 64. These individuals were monitored over a 19-year period, from 1997 to 2016, as reported in a press release.
Participants were asked to provide information about their sitting habits, physical activity levels, and other lifestyle choices. Dementia diagnoses were subsequently identified by cross-referencing this information with Swedish health and death records.
The study found a notable correlation: mentally active sedentary behavior was associated with a “significant reduction in dementia risk” when compared to more passive forms of sitting.
While the study was conducted in Sweden, the press release indicated that the findings are likely applicable to a broader global population. This suggests that the results could contribute to informing public health guidelines and preventive strategies aimed at reducing the incidence of dementia worldwide.
In a statement, the lead researcher, Dr. Mats Hallgren from Sweden’s Karolinska Institute, emphasized that the study underscored the critical distinctions between passive and mentally engaging sedentary habits concerning brain health.
“While all sitting involves minimal energy expenditure, it may be differentiated by the level of brain activity,” stated Dr. Hallgren.
“How we utilize our brains while we are sitting appears to be a crucial determinant of future cognitive functioning and, as we have shown, may predict dementia onset.”
Sedentary behavior is characterized as a “ubiquitous but modifiable risk factor for many health conditions, including dementia,” according to the researcher.
“Our study adds the observation that not all sedentary behaviors are equivalent; some may increase the risk of dementia, while others may be protective,” he further elaborated. “It is important to remain physically active as we age, but also mentally active — especially when we are sitting.”
The Centers for Disease Control and Prevention (CDC) projects that by the year 2060, nearly 14 million American adults could be living with Alzheimer’s disease.
In related news, a recent study published by the Alzheimer’s Association found that an individual’s biological age might be intrinsically linked to their risk of developing dementia.

Furthermore, researchers have also recently discovered that a higher consumption of unprocessed meat could potentially offer protection against dementia in older individuals who possess a specific gene variant.
