Oral health may be linked to risk of dementia
When it comes to preserving mental health, small day-to-day details can make all the difference. Proof of this is a study published in the Journal of the American Geriatrics Society . According to the survey, conducted by a specialist at the University of California, California, , people who maintain healthy teeth and gums have a lower risk of developing dementia throughout their lives. more than 5,400 elderly people were followed for 18 years. They were all part of a California retirement community and were between the ages of 52 and 105. None of them had any traces of dementia at the start of the study. Throughout the analysis, they answered questionnaires about the oral care they took, the condition of their teeth and whether they used dentures. At the end of the study, 1,145 elderly people had been diagnosed with dementia. They then discovered that it is not just an individual's mental state that may help predict their oral care, but their oral health may also influence the risk of losing cognitive ability. Thus, participants who reported brushing their teeth less than once a day were 65% more likely to develop dementia than those who performed daily hygiene.
Experts suspect that bacteria typical of gum disease can migrate to the brain, causing inflammation in the organ. Thus, the damages caused would anticipate the emergence of mental problems. However, the researchers say that it is not possible to say that oral problems are the cause of dementia.
Know other risk factors for dementia
Another study by researchers from the
San Francisco VA Medical Center
in the United States, was able to map the six main dementia risk factors: sedentary lifestyle, alcohol use, depression, smoking, diabetes, middle-aged hypertension and obesity. Understand how they can affect brain-vascular health. 1. Metabolic Syndrome The metabolic syndrome elevates the incidence of stroke and increases oxidative stress. It is the association of diseases such as obesity, hypertension, hyperglycemia, increased triglycerides and decreased good cholesterol (HDL). Together, they can increase memory loss by up to 40%.
The intensity with which the blood circulates in the hypertensive ends up causing lesions in the vessels, including those of the brain. This causes oxygenation and nutrient distribution to be impaired and may affect mental health.
Smoking accelerates the neurological aging process and can cause brain atrophy, increasing the risk of Alzheimer's. The toxins present in the cigarette are also responsible for the death of neurons, which accelerates cognitive degeneration.
The consumption of more than two daily doses of alcohol increases the risk of neurological disorders by almost 10%. In the case of the chronic alcoholic, then, there is loss of brain tissue, causing the brain to shrink. This worsens problems of forgetting and recent memory loss.
Agência Brasil - Scientists announced yesterday (7) the development an effective and cheap method to destroy the eggs of the mosquito that transmits the dengue and the Zika virus, resorting to an odor The researchers from Canada and Mexico tested the method in an urban and remote area of Guatemala and found that they had destroyed seven times more eggs than with common traps in the same areas.
The skin that covers the head (glans) of the penis is called the foreskin, it is elastic and during erection or when the skin is pulled back the glans is exposed . Fimosis is when the difficulty or even impossibility of exposing the glans due to a narrowing of the foreskin occurs, forming a ring. This narrowing of the foreskin may occur congenitally (from birth) or be acquired throughout life following repeated inflammation of the foreskin.
