The open-access journal PLOS Medicine published a study published on November 16th that found drinking coffee and tea to be associated with a lower risk of stroke and dementia. The risk of dementia after stroke was also reduced with coffee consumption.

A stroke is the leading cause of death for ten percent of people. Dementia is a global public health issue with considerable economic and social implications and results from the decline of brain function. Post-stroke dementia is characterized by dementia-like symptoms.

Drinking Coffee And Tea May Reduce Stroke And Dementia Risk

If your brain does not receive the oxygen and nutrients, it needs due to interruptions or reduced blood flow, a stroke occurs. Your brain begins to die shortly thereafter.

The earliest possible treatment for a stroke is imperative. Taking action early may reduce the likelihood of permanent brain damage.

Drinking Coffee And Tea May Reduce Stroke And Dementia Risk

Fortunately, stroke deaths are on the decline among Americans. In addition to preventing stroke-related disability, effective treatments are also available.

In Alzheimer’s disease, memory and cognitive function are deteriorated beyond what is expected from normal biological aging. It is usually a chronic or progressive condition. Affected by the effects of memory loss are alignment, understanding, computation, learning ability, vocabulary, and judgment. There is no effect on consciousness. There is often an accompanying and sometimes preceding behavioral, emotional, and motivational change.

Dementia can be caused by other diseases and injuries as well as Alzheimer’s disease and stroke.

WHO data show that dementia is among the leading causes of death among all diseases and is also one of the leading causes of disability and dependence among the elderly globally.

The physical, psychological, social, and economic effects of dementia affect not only those with it, but also caregivers, families, and society as a whole. Dementia patients are stigmatized, and as a result, unable to receive appropriate treatment and diagnosis.

Yuan Zhang and colleagues analyzed the data from Tianjin Medical University in Tianjin, China, which examined 366,682 participants recruited between 2006 and 2010 and followed until 2020. Participants self-reported the amount of coffee and tea they consumed at the outset of the study. At least 10,053 participants had more than one stroke during the study period.

Two to four cups of coffee and tea a day or a combination of four to six cups of coffee and tea per day were associated with the lowest stroke or dementia incidence rates. The risk of stroke and dementia was lower among those who consumed 2-4 cups of coffee or tea daily as compared to those who did not drink them. It has also been shown that drinking coffee alone or in combination with tea lowers the risk of dementia after stroke.

It may be difficult to generalize these associations based on this sample, which differs from the general population. It is difficult to project dementia and stroke rates to a larger population due to their low rates of prevalence. Furthermore, an association between coffee and tea consumption and strokes, dementia, and post-stroke dementia cannot be used to infer causality.

Our study suggests that moderate consumption of either coffee or tea, individually or in combination, is associated with a lower risk of strokes and dementia.”
