Why cholesterol drugs might affect memory
Dr Duane Graveline has agreed to share his comments on the article in Scientific American with you:  
“When  I saw Melinda Moyers’  first mistake I was amused  for my morning walk
took place in Island Pond, Vermont not Merritt Island  Island, Florida where
I currently reside. It was then I spotted the title  “Why cholesterol
drugs  might affect memory’ and began to get angry. I had spent 15 years
documenting  the cognitive side effects of statin drugs and our FDA’s
Medwatch had recently  reported over 7500 statin associated transient
global amnesia and memory loss  reports received during the time period
2004-2014. A reasonably accurate title  would not read cholesterol
lowering drugs might affect memory. The proper title  would read
cholesterol lowering drugs affect memory.
If Ms Moyer has done her  job
she would know these facts just as I know them so why not use them.

Then
 when my name came up again in the article I was surprised to read I
had been  “following a healthy diet to keep my cholesterol low.” Never
since  my research on the subject have I been even remotely concerned
about my  cholesterol. It is irrelevant to heart attack and stroke.
Inflammation is the  underlying cause. Many times in my writing I have
told my readers how ashamed I  was to have raised my family on no eggs,
skim milk and margarine for 17 years so  conned I had been as a much
younger doctor. Had Ms. Moyer but asked me I would  have told her this.
And then she topped it off by saying “he says he has never felt better.”
Now  I am really angry for she has never in the past decade asked me
and since  the year 2000 I have almost completely lost the ability to
walk. I barely make  it with cane and walker and am but a moment away
from wheelchair existence.  Peripheral neuropathy says my neurologist
with my muscle biopsy showing  denervation atrophy (no nerve, no
muscle). Ms Moyer conjured up this entire  thing. If she had only called
me.

It’s Not Dementia, It’s Your Heart Medication: Cholesterol Drugs and Memory

Cholesterol – look after it!

All
cholesterol molecules throughout the known universe are identical
in every respect. There
is no such thing as ‘good’
or ‘bad’ cholesterol. This
erroneous idea was ruthlessly exploited to market statins. The ‘good’
and ‘bad’ labels actually describe two classes of blood fats (lipids)
also known as HDL and LDL both of which are vital to our lipid
circulation of fatty nutrients.


We
now know that LDL supplies essential fatty nutrients to all organs of
the body. The HDL is in effect the smaller ’empties’ returning the
waste fats to the liver for disposal or recycling.


Excess
dietary sugars can damage the Lipid LDL marker making it unusable.
That damage can be measured (HbA1c is a useful surrogate test for
sugar-damage). When LDL is damaged it builds up in the blood and less
HDL is returned from the organs of the body. The organs are starved
of vital fatty nutrition.


Statins
reduce the symptom of LDL build up but do nothing to fix the problem
of organs not getting fat soluble nutrition. Ultimately statins will
just add to the harm caused by sugar-damage.

Conflicting Evidence – A Statin Paradox

We know that all cells (all tissues) cease their exocytosis and endocytosis  activity, if the membrane cholesterol content drops by
around 10%.  This is easily achieved on statin therapy. Everything slows down.

In the case of bone remodelling both osteoclasts (cutters) and osteoblasts (builders) will reduce their repair activity in bone remodelling.
Calcium loss from bones will be reduced but micro-fracture repairs will not be repaired on statin therapy. Bone density is maintained on statin therapy but the developing micro-fractures weaken the skeleton.

It’s all about what is measured and how long you follow through.
Statin trials can be designed to prove both benefit and detriment to bones.
This is why experimental osteoporosis treatment by statins  to maintain bone density ultimately gives way to increased fracture risk.
Two competing bone remodelling processes are failing and conflicting measures can be used to conflict statin safety.

You will find this pattern repeats in damage and  repair of myelin in MS studies.

Autoimmunity and T2D

My anecdotal experience and studies have shown me thIs:-

Glycoproteins are important on cell surfaces (extracellular matrix) they are anchored by dolichols and form an important part of the communication between tissue and immune system, with recognisable sequences of sugars deliberately assembled for the matrix. This is structural sugars in the body assembled by enzymes in the normal cellular machinery.

Glycation damaged proteins (AGE). These are exposed proteins who randomly become attached to a mono-sugar (usually glucose but recently increasingly fructose) attaching to lysine by the maillard reaction).

In cooking at oven temps this is a desirable and flavoursome reaction at some speed.

In diabetics this is a very slow (decades at body temp) degradation of lipid receptor mechanisms, elastins and collagens.

Auto-immunes and T2D

The body has a clean-up immune response to random AGE mono-sugar attack, which is overwhelmed as we age and develop T2D (over decades). The suagr damage effect is present in many tissues showing a strong immune response (arthritis, eczema) which often respond well to carbohydrate restriction and increased dietary use of ‘essential fatty acids’.

Cholesterol & Insulin

diabetes [9]. The underlying mechanisms of the
potential adverse effects of statins on carbohydrate
homeostasis are complex [10] and might be related
to the lipophilicity of the statin [11]. Indeed,
retrospective analysis of the West of Scotland
Coronary Prevention Study (WOSCOPS) revealed
that 5 years of treatment with pravastatin reduced
diabetes incidence by 30% [12]. The authors
suggested that although lowering of trigliceride
levels could have influenced diabetes incidence,
other mechanisms such as anti-inflammatory action
might have been involved; however, in the
multivariate Cox model, baseline total cholesterol
did not predict the development of diabetes [12].
Furthermore, pravastatin did not decrease diabetes
incidence in the LIPID trial which included glucose-
intolerant patients [13]. On the other hand, in the
JUPITER trial (Justification for the Use of Statins in
Prevention: an Intervention Trial Evaluating
Rosuvastatin), which studied apparently healthy
persons without hyperlipidemia but with elevated
high-sensitivity C-reactive protein levels [14], the
risk of diabetes was increased by a factor of 1.25
[95% confidence interval (CI), 1.05 to 1.51] among
individuals receiving rosuvastatin 20 mg daily with
respect to placebo. Strikingly, among persons
assigned to rosuvastatin, the median low density
lipoprotein (LDL) cholesterol level at 12 months was

55 mg per deciliter [interquartile range, 44 to 72
(1.1 to 1.9)].
It is intriguing that salutary lifestyle measures,
which might exert their beneficial action through
an anti-inflammatory mechanism without a strong
cholesterol-lowering effect, beyond reducing
cardiovascular events and total mortality, reduce
also the risk of diabetes and other chronic
degenerative diseases. This fact may represent
a ‘justification’ not to use a drug in low-risk primary
prevention populations: lowering cholesterol at the
expense of increasing diabetes might be counter-

productive over the long-term.

Good or Bad Lipid Profiles

The 2013 Nobel Prize for Medicine raised expectations of a parallel discussion of extra-cellular lipid circulation in The Lipid Cycle. A better understanding of the health problems caused by disruption to The Lipid Cycle has been blocked for over 40 years by incorrect use of the chemical term ‘cholesterol’ as an inaccurate surrogate when referring to Lipid profiles. This singular error has caused decades of misunderstanding and inappropriate treatments in medicine.

The Lipid Cycle

The build up of damage to the LDL class of lipids is on the supply side of lipid circulation in the blood has erroneously been referred to as ‘Bad Cholesterol’.

Understand this means it should have better been called ‘Bad-LDL’.

Undamaged or healthy ‘Good-LDL’ on the supply side delivers fatty nutrients to organs and tissue in a controlled manner (receptor-mediated endocytosis). Bad-LDL remains in the blood until scavenged into adipose tissue.

The HDL lipid class operate on the return side of the lipid cycle and is depleted when LDL is damaged.
