The traditional medical system has been totally in the dark when it comes to the underlying causes of Alzheimer’s and other types of dementia.
And how can you cure something when you don’t even know how it happens?
But a new study from Amen Clinics, UC Irvine, Johns Hopkins University, and Thomas Jefferson University reveals not just the cause of Alzheimer’s but also the exact mechanism of how it happens.
Which leads to a simple, free way to cure it.
These researchers used brain imaging scans already obtained from previous research work at the Amen Clinics. Altogether, they had access to 35,442 brain scans taken from 17,721 adults between ages 18 and 94. Their average age was 40.8.
The scans of 128 of each participant’s brain areas were taken both while they were at rest and while they were engaged in a concentration task.
They were then categorized into underweight (BMI less than 18.5), normal weight (BMI between 18.6 and 24.9), overweight (BMI between 25 and 29.9), obese (BMI of 30 and up), and morbidly obese (BMI of 40 and up).
For all ages, brain function and blood flow declined progressively as BMI increased. This was true for almost all regions of the brain and both while the participants were at rest and concentrating.
This pattern was especially striking in the areas particularly involved in Alzheimer’s disease, namely the temporal and parietal lobes, the hippocampus, the posterior cingulate gyrus, and the precuneus.
For these areas, activity and blood flow started to decrease from normal weight, and then further to overweight, obese, and morbidly obese.
This is depressing when considering that the Centers for Disease Control and Prevention has calculated that 72 percent of American adults are overweight and 42 percent of them are obese. Sadly, 40 percent of young people aged 20 to 39 are obese, as are 44.8 percent of those between 40 and 59, and 42.8 percent of those above 60 years.
On the upside, a study like this shows in no uncertain terms that dementia and Alzheimer’s disease are lifestyle diseases that can be prevented using healthy dieting and exercise to lower body weight.
