Maintain Weight Loss order Brain Stay Sharp
Want your brain stay sharp when old? Keep your weight. So said the research results from the University of Arizona. High body mass index have a negative impact on brain function of elderly.
Keeping the weight it can protect the body from a variety of health problems. Benefits lighter body, it can reduce the risk of cancer, heart disease and diabetes. Previous studies have linked weight and health of the brain, but there is no research that examines how the two affect each other.
"" By finding that, scientists could potentially develop interventions to prevention of cognitive decline, "" Kyle said Bourassa, a doctoral student of psychology and co-author of the study.
Bourassa and other researchers suspect systemic inflammation - chronic excessive reaction of the body's immune system may be responsible here, because previous research proves inflammation in the brain have a negative impact on cognitive function. Also already known are overweight causes inflammation throughout the body. "" The higher the body mass index, the greater the inflammation that, '' he said.
To explore this relationship, Bourassa and other researchers analyzed data of persons aged 50 and over who have a body mass index higher levels of inflammation and cognition scores were tested several times over the past six years.
Body mass index, measuring the weight associated with the high is often used to determine whether a person is normal, underweight or overweight.
For individuals, the body mass index is not necessarily a measure of the degree of health. But for a large population, this index is a good way to estimate the average. In general indices normal count 18-25. On top of the 25 classified overweight.
For the study, inflammation was measured by the presence of C-reactive protein (CRP) - a marker of systemic inflammation throughout the body contained in the blood of study participants. Cognitive function was measured with the mention of the word and verbal fluency tests.
Researchers found a clear association of these three factors. "" The higher the body mass index at baseline, the greater the CRP levels over the next four years, ' "said Bourassa. CRP changes then predict the decline of brain function, including executive function and memory, two years later.
In other words, the study found "" a person's body mass index predict cognitive decline them through the levels of systemic inflammation.
One of the researchers, David SBARRA, psychology professor cautioned that the study does not prove a causal relationship because it only monitors the people from time to time.
To find a causal relationship, the study needed a way to reduce body mass index through controlled conditions and examine their effect on inflammation and cognition.
But the researchers said their findings may provide new insights for further studies and interventions that could be done. "" If you have high inflammation, in future, we recommend using anti-inflammatory drugs not only reduce inflammation but also helps cognitive function, ' "said Bourassa.
