Can Cholesterol be too low for the brain?

Lab from Nov 2014

I obtained a break down of specific cholesterol levels as my LDLp was extremely low. 

Mayo only tells me my desmosterol is at a normal level but not too low?

Subsequently I was diagnosed with Alzheimer's in Dec 2017.

This week I learned of a lecture from Peter Toth stating that low cholesterol does not cause dementia but probably prevents Alzheimer's.

My systolic blood pressure runs between 100-120.

Perhaps my biggest problem is Diabetes Mellitus with Hgb A1c from 7.0 to 8.0

I do have apoE 4 positive in one allele.

My advise keep:

1- non-HDLc less that 100
2- systolic BP around 120
3- check insulin level and fasting glucose.

If fasting glucose greater than 95 go on Low Carb High Fat diet lose 5 lbs and don't gain weight.

Walking and weight lifting also a good idea.



Desmosterol level  of 1.2 mg/l for me is normal according to Mayo Clinic result above.

Difficult to find out what a low Demosterol is?

I am back on Lipitor (atorvastatin) 5 mg with Zetia and Endur-acin. I get my apoB level this week.


A talk this year(2019) given by Dr Peter Toth says there it is more likely that statins lower risk of cognitive impairment.
