Coffee, an unexpected ally against dementia for hypertensives?
He coffee one of the world’s most popular drinks, valued by people of different cultures, religions and countries. Although his excessive consumption may have adverse health effects, new research finds which may help prevent dementia.
A team of public health researchers from Ningxia Medical University in China found by analyzing data from medical records that some regular coffee drinkers with high blood pressure they can have a lower risk of developing dementia than non-coffee drinkers. His studies was published in Scientific reports.
The dementia It is the result of various diseases and injuries that affect them brain. Disease of Alzheimer’s disease It is the most common form of dementia and can present between 60% and 70% of casessays the World Health Organization (WHO).
According to the new message published Lancet from the world’s leading dementia experts, this disease can be prevent or delay 45 percent of cases bringing under control 14 risk factorsbetween them hypertension. Treatment of this disease can reduce 2 percent risk of dementia.
In this new study, researchers asked whether a direct relationship could be established between beverage consumption caffeine and dementia. To find this relationship, they turned to British Biobankhealth database more than 500,000 people in a few years.
In their analysis, the research team looked for association between regular coffee or tea consumption and a reduced risk of dementia. They also looked at other factors that could play a role, such as whether people had heart disease or other conditions, including hypertension.
The study authors said: “Dementia is common in people with and around hypertension 11 to 20 percent of dementia cases related to abnormal blood pressure. Hypertension is accelerating cognitive aging and increases the risk Alzheimer’s disease and other dementias. “Prevention of hypertension not only reduces the disease burden, but also has the potential to significantly reduce the incidence of dementia in the medium and long term.”
Previous studies have shown that regular drinking of moderate amounts of coffee or tea can reduce inflammation. Other research has shown that it can also support the health of the blood-brain barrier. Both factors were associated with reducing the risk of developing dementia.
Recently, according to a studies published in the open access journal PLoS Medicine, The Dementia risk reduced by 28%and stroke by 32% in people who reported consuming two to three cups of coffee and a similar amount of tea each day. This indicated that their risk of developing dementia was reduced to 1 in 100 and 1 in 50 for stroke.
Scientists from Ningxia Medical University found this out people with hypertension were more likely to develop dementia than those who did not suffer from the condition. They also found an association between people with hypertension who also regularly drank coffee or tea: those who Those who drank between half a cup and a full cup each day had a lower risk of dementia than those who did not drink any of these beverages.
They also found that the type of coffee consumed varied: Better results were achieved, for example, by those who ground their own beans.
The research team suggested that the consumption of caffeinated beverages by people with hypertension and the associated reduction in inflammation caused by this consumption are likely reasons reduced risk of dementia.
They also noted that because their study was correlational, more research is needed to better understand the link between caffeine consumption and dementia risk in hypertensive patients.
