Obesity has always been a cause of worry. Numerous researches have been conducted to determine health hazards caused by excessive body weight. A recent study has suggested that carrying too many extra pounds during the life may take its toll on the brain as well as the body.
The study led by Swedish researchers, found that females who were obese throughout their adult lives were more likely to lose brain tissue, a condition known as brain atrophy that has been linked to impaired brain function and dementia. The study showed that obesity might be a risk factor for dementia in females.
In the study, researchers followed a group of 290 women between the age group of 45 to 60 years. The study continued for 24 years and during this period all of the participants had four follow-up exams. At the last exam, the participants underwent computed tomography (CT) scan to measure for any brain atrophy.
Later, the results of the CT scans were compared with the women’s body mass index (BMI) and found that being overweight or obese increased the risk of brain loss in the temporal region of the brain, which plays an important role in language, memory and hearing.
BMI between 18 and 25 is considered normal, if the BMI between 25 and 30 is considered overweight and a BMI over 30 is considered obese. The study showed that women with brain atrophy had, on average, a BMI that was 1.1 to 1.5 points higher than women without brain atrophy. The researchers also found that the risk of brain atrophy increased 13% to 16% per each increase in the women’s BMI. But the study couldn’t establish how obesity leads to brain tissue loss; they only suggested that obesity increases the risk of diabetes and high blood pressure, both of which can cause damage that may lead to brain atrophy.
