and I WON'T forget your link!

that statin as the cause of memory problems, when any slowing of memory may be caused by the natural aging process?

I take atorvastatin. I've been taking a statin for about 25 years.
I'm 75.
Yes, I have short term memory 'deficiency'.
I call it deficiency, because sooner or later I can usually remember whatever it is.

Not immediately, but a few minutes later, especially if I don't think about what I was trying to remember.

Sometimes it's a few hours later.
It goes this way:
That guy who played Hans Solo in Star Wars?
You know.
The guy who played Indiana Jones?
That guy.
He was in "Air Force One"?

2 a.m. I get up to take a leak and "OH HELL, HARRISON FORD!"

P.S. I don't wake Miz t. up to tell her this.

about it at first but not much later saying it wasn't real.

These articles reference a JAMA article, and talk about other possible reasons for the correlation. I'm a nurse, working with people in their homes, including DD people who were concerned at the initial reports.

my pain was focused in the feet and legs - horrendous muscle cramps. I tried about 5 different brands.

Last year, my new doctor (I moved) started me on Pravastatin, and so far I have been able to take it just fine. Everyone is different, but you might look into it.

but I've seen ads on TV for a class action suit against the makers. Apparently it's related to type 2 diabetes. You'll have to google for more info, that's all I know.
