Statins For Alzheimer's?
The fight against Alzheimer's took a positive turn after a study found that people prescribed cholesterol-lowering statins had a decreased chance of developing dementia. Dr. Jon LaPook reports.

The study followed more than 1,600 people over the age of 60 for five years. Those who were taking a cholesterol-lowering statin such as Lipitor, had a surprising result.
They were about half as likely to develop either early signs of trouble thinking or full-blown dementia.
Research has shown that giving statins to patients who already have Alzheimer's does not seem to help. But today's study looked at people before any hint of dementia.
"What it tells us is that statins might not be effective in slowing the progression of disease, but they might ... prevent disease," said Mary Haan of the University of Michigan.
Since cholesterol is part of the tell-tale plaques on the brains of Alzheimer's patients, it made sense to think that statins might help.
"It seems as though the statins because they lower cholesterol reduce production of these plaques," said Dr. Gayatri Devi.
High cholesterol is one risk factor for dementia - but experts stress focusing on all risk factors.
"... obesity, smoking, certain types of genetic predisposition," Devi said.
And despite this study, there is not enough evidence to prescribe statins for the brain.
A patient calls you up and says "I'm losing my memory a little, would you be tempted to put them on a statin, LaPook asked.
"No, no, I think if they have high cholesterol, then absolutely, yes then that's a good time to put them on statins," Devi said. "But statins as prevention for Alzheimers is not indicated at this time."

How fortunate that Erectile Dydfunction, the malady of millions, is now preventable. What''s really terrific is to constantly view proof of this scourge and the treatment, over and over on the television. How nice that the "right" moment can be postponed. If only priapism were fatal. That would be a blessing.
Reports of niacin''s link to dementia prevention is also well documented.

Who is correct???
"Might prevent disease"; What study? I''m sure this is a rebuttal by the drug companies of the University of Rochester study.
The advent of the stronger statin drugs in the past decade has contributed to a flood of reports of impaired cognition. Only in the past several years have we learned the importance of cholesterol in brain function.
Explanation for statin drugs'' effect on cognition came on 9 November 2001, when Dr. Frank Pfrieger of the Max Planck Society.
The so-called glial cells of the brain, long suspected of providing certain housekeeping functions, were shown to produce their own supply of cholesterol for the specific purpose of providing nerve cells with this vital synaptic component.
The brain must depend upon its own cholesterol synthesis, which the glial cells provide. The highly lipophilic statin drugs more easily cross the blood/brain barrier and interferes directly with glial cell synthesis of cholesterol.
Millions of patients are now taking this class of drug and are at significant risk for cognitive side effect. Transient global amnesia is just the tip of the iceberg. For every report of TGA there are hundreds of reports of impaired memory, disorientation and confusion among an older group of patients that rarely get mentioned.

- Since 1999, Public Citizen has called on the FDA to put black box warning on Lipitor as well as other statins, saying they are concerned about possibly deadly side effects. Public Citizen director Sidney Wolfe has said there were over 50 deaths related to statins, and he was concerned that there wasn''t enough public awareness over the drug''s problems.

See all 13 CommentsIn 2001, a high profile withdrawal of the drug Baycol, by the maker Bayer, occurred after several deaths relating to a muscle degenerative disease called rhabdomyolysis. Baycol is also a type of statin, similar to Lipitor. Merck spokeswoman Donna Cary recently stated that their company''s drugs, Mevacor and Zocor, might have also been related to some undisclosed amount of deaths.
