Because for whatever reason, they just don’t diagnose dementia. My father suffered from dementia, but all his lab signs were normal, and they gave him a clean bill of health.
They are not a Democrat subjected to listening to the likes of ∅™, Pelosi, Reid, Maxine Waters, Debbie Wasserman Schultzie, Sharpton, JJ , a host of the other usual suspects including MSNBC, CNN, NPR, etc.
Some liked to point out that cancer diagnosis is more common in nations with advanced medical care that are (gasp! the horror!) industrialized - trying to say that industrialization causes cancer - that if we all lived in a pristine natural environment we would have lower cancer rates.
While there may be some truth to that, once separated from the outlandish claims; the truth of the matter is that even if cancer rates were exactly the same - one is more likely to get DIAGNOSED with cancer where there is advanced medical care.
An old Guatemalan in a hut may or may not get his stomach cancer properly diagnosed - but even without a proper diagnosis - he still got stomach cancer. And absent a proper diagnosis and proper care - he is much more likely to DIE of the cancer.
But you ask his family what he died of - they say - ‘He was old, had stomach problems, blood in his stool, and then died.’.
Wow - so he didn't have cancer! Miraculously free of cancer! People in Guatemalan pastoral living conditions are less likely to get (diagnosed with) cancer!
The majority of my dementia pt.s (hospice nurse) are mostly healthy otherwise.
Dementia pt’s usually die of aspiration pneumonia after they lose the ability to swallow their food/drink.
AFAIK, tests for dementia are initiated because the patient is starting to exhibit symptoms thereof. In those 3rd-world environments, those symptoms are far more likely to get you killed.
Consider a common symptom. A red flag for dementia is turning the kitchen stove on and leaving it on unused; in a first-world environment there are layers of safety protecting against the consequences of that mistake (metal surfaces, fireproof/resistant counters, smoke detectors, fire departments). The equivalent mistake in a third-world environment would burn the house down.
Many diseases seem prevalent in developed countries only because other dominating diseases have been mitigated. Cancer is more common where food poisoning isn’t.
It could also be environmental and diet. They might live closer to the earth, eating more natural things and less processed things. Less vaccines (including flus). Less chronic inflammation in the body. Less sugar.
If they are actually poor, they may also have periods of fasting, or overall low caloric intake. That can help too.
My grandmother was an avid reader, several books a week; didn’t spare her from senile dementia.
