Middle-Age Obesity Linked to Dementia Among Elderly

A study published in the journal Neurology reports that people who are obese in middle age are almost four times more likely than those of normal weight to develop diseases that lead to dementia in later life.

Exactly why obesity leads to an increased likelihood of dementia is not understood, but researchers note that fatty tissue produces more hormones than any other organ in the body, many of which are known to be harmful. —ARK

The Guardian:

The study, published in the journal Neurology, examined data on more than 8,500 people over the age of 65. Of the sample, 350 had been diagnosed with Alzheimer’s disease or vascular dementia and a further 114 had possible dementia.

... Exactly how excess weight can influence the degradation of the brain is not certain, but Xu said there could many possible mechanisms. “Higher body fat is associated with diabetes and vascular diseases, which are related to dementia risk,” she said.

In addition, fatty tissue is the largest hormone-producing organ in the body and it can produce inflammatory molecules which may affect cognitive functioning or the process of neurodegeneration.

Sorensen said that further research was needed to find the links between being overweight and dementia. “One in three people over 65 will die with dementia, yet research into the condition is desperately underfunded.”

Idk, I haven’t read that actual study, but it kinda seems like the researchers are a little too eager to make an association.  We all know that correlation does not equal causation, and I have a feeling that there are some factors that have yet to be accounted for.  This is just wild speculation here, but we know that people that are overweight are usually more sedentary, which means a slower metabolism.  We do know that a slower metabolism can lead to the buildup of amyloid plaques in the brain, which could be why it appears that stomach fat is causing dementia. I believe there’s an article on http://www.stomachfat.com about a study that confirmed that slower metabolisms cause amyloid plays to linger in the brain longer…

Once again, the ignorance of fat in the diet allows for a
seemingly innocuous idea that no fat would contribute to one
not and never having any dementia. If the brain is made of lots
of fats of different kinds, it seems normal that the brain to
function properly would require the right fats in the right
amount to totally dismiss the idea is pure ignorance and
arrogance. Being several factors involved I would still say that
fats carry a lot of weight how how the brain functions and does
cut it.

That might explain why the religious often seem demented to me.

No, that would more accurately be “delusional”—invoking people who aren’t there.  I saw my mom doing that from anesthesia she had been given…when it wore off she was just demented—ie, didn’t remember seeing the people who weren’t there.

I know it sounds funny, and we try to laugh, but that’s just to keep ourselves sane….

My grandfather, always the gentleman and never fat, suffered from dementia after my granmother, a nurse died.  He had high blood pressure and stopped taking his medication when she wasn’t there to make him take it.

Dementia is caused by so many factors, some of them genetic.  Fat equals senile just doesn’t cut it.

And religious Americans are twice as likely to be obese:

I doubt the research will be done as it goes against the
ostensible idea that a high carb, low/no fat and some protein
diet is the best diet.

But there is thinking that, it is with fats that are a key ingredient,
to the pre-agri diet. Up until the beginning of the agricultural
age, the diseases of modern man were scarcely found in the
remains of those hunter gather groups.

Research in the mummies of Egypt bear this out. Oddly enough
one just doesn’t find those researches if, one was curious to
look. But there is and oddly again, there is research that is for
the most part vehemently scoffed at.

I know you probably expect people to say “Where does TDoff get his funny ideas?” but realistically people are more likely thinking: “Where does TDoff get the idea he is funny?”

With an aging mother, who was never obese, or even overweight, now rapidly sinking into increasing dementia, and having seen other relations and friends’ parents sink into it as well without a history of obesity, I wonder about the validity of the study or if the difference they find is actually statistically significant.

Dementia, is, technically, solely the loss of memory.  But it can be so severe that one can forget what one was speaking about 30 seconds ago, and makes the victim seem delusional.  At its worst, victims forget how to speak, how to eat, and sometimes, even how to chew and swallow.

One is caught between wanting one’s loved-one to have the best of what is left of life while they can, and for the peace of it being over as restrictions and limits build up, and less and less dignity is retained.

This just confirms the obvious, that horny seniors are driven crazy when they try to have sex with a fatty, and can’t contort enough at their advanced age to get it in.
