Bad news for me as my bi-yearly government mandated health checkup came back with some bad cholesterol results.
The study was done on old people though.
Could changes in cholesterol be a warning sign of dementia?
A new study suggests that older adults whose cholesterol fluctuates significantly over time are more likely to develop dementia than those with stable levels.

Note that the study does not prove that cholesterol changes cause dementia — only that there is a connection between the two.
Nutrition studies are mostly very low quality. Nina Teicholtz has a new article out:
US Dietary Guidelines: Science is "Subpar," Cannot be Replicated: New paper finds systematic reviews to be of “critically low quality"

I recommend the book The Big Fat Surprise, by Nina Teicholtz. It's an amazing journey through our nutritional guidelines, how the "science" going into them was a giant tarball of special interests and poorly done research.
I wrote a more involved review of The Big Far Surprise here: #320715
That book really took the scales off my eyes. I no longer believed the standard narrative (low-fat, fruit, vegetables, and fiber is good, meat, eggs, butter, saturated fat is bad). I started reading and listening to carnivore authors, and am now carnivore. Best thing I've ever done for my health.
Control is hard:
This makes me curious about potential causes for cholesterol fluctuations. Presuming this isn't causal, what is?
It's very hard, indeed.
Known reasons for cholesterol changes can vary among
So, unless the study accounts for these, seems like cholesterol change might just be at best an indirect marker of potential risk to develop dementia.
