Overweight- Huge Study conclude Obesity affects mental ability

Are you Overweight?
It turns out that not only your body deal with it - but also the brain. A new study says that obesity causes damage to memory, concentration and fluency. Another finding: mental ability of overweight people is like people who are seven years older then what their actual age.

Overweight people are at risk of developing diabetes, high blood pressure and soaring cholesterol levels - Obesity causes a lot of trouble. Now it turns out that in addition to the countless physical dangers, overweight people also expect mental risks. New research has linked obesity - excessive and cognitive decline in activity of the brain, and states that it can affect concentration and memory.

Revolutionary research was published on August 21 2012 on ‭ "Norology" Reputed international magazine published by the American Academy of Neurology. It included ‭ 6401 British participants aged 35 to 55 in two main groups: overweight and normal weight. The study was conducted for not less than a decade, during which the researchers examined the cognitive ability of the participants three times at different time points. They tested them three skills needed for everyday  functioning, short-term memory, reasoning ability and fluency.

The researchers found that participants in the study had a decline in cognitive ability. In other words: The more advanced your age, no matter if you are overweight or thin, so you will experience a decrease in concentration and memory - and with it, there is not much to do. But the results were really surprising about Those with extra weight. According to the study, those who suffered from extra weight Showed a more significant decrease in brain activity compared with normal weight.

Those who their obesity was accompanied  with metabolic problems - diabetes, high cholesterol or high blood pressure - had shown even worse results. Cognitive decline in subjects from this group was faster at ‭22.5% - from normal weight. According to the researchers, intellectual ability of all overweight tested was like seven years older people than they really are.

What is the reason why obesity affects concentration and memory abilities? That, the researchers did not respond. But Nathan Borenstein, chairman of neurologists in Israel and director of the brain stroke unit at the Department of Neurology - Ichilov Hospital, explains that there are many options for that phenomenon. According to him, diabetes and high blood pressure often suffer from, people with a higher body mass (BMI), sometimes leading to vascular disease, including blockages in the small blood vessels in the brain, or to changes in the material responsible for the transfer of information within the brain - creating a communication problem.

According to Prof. Bornstein, because many overweight people have pauses in breathing during sleep, less oxygen reaches the brain - and this can harm mental abilities.
Another possibility is that Hormonal changes cause fat cells that lead to change the chemical balance in the brain. And as if all these reasons are not enough, the lack of physical activity leads to deterioration in cognition. "Of course not every person suffering from obesity suffer a decline in cognition," Reassured yesterday Professor Borenstein, "but it only emphasizes how important it is to maintain weight and to exercise. It also prevents stroke and maintain cognition, and actually catch two birds with one stone."

Another finding refers to the relationship between obesity and aging. It turns out, trouble causes obesity in mid-life reach a point especially dangerous at the age of 70, then cognitive decline becomes steeper and worsens. Although mental ability damage at that age does not necessarily come into dementia or Alzheimer's, but it also can be harmful even more to concentration and also to memory.
