Hi Kathie, you may be interested in accessing a web site developed and maintained by Dr. Duane Graveline, MD. He is a family physician who trained as a NASA astronaut; he developed temoprary global amnesia from lipitor, and has devoted his time and energies to the study of adverse effects of statins. one of the points he makes over and over again is that statins have not been proven to be of benefit to the elderly or to women. muscle weakness is the most common complaint and peripheral neuropathy figures prominently in the list of complaints. his web site is: spacedoc.net. best of luck to you and your dad.
