Statins do not protect against dementia

Bernadette McGuinness and her colleagues analyzed the findings of two large clinical trials probing the health effects of statins: one study investigated the effects over five years of simvastatin (Zocor) in 20,536 patients; a second study followed 5,804 patients taking pravastatin (Pravachol) for an average of 3.2 years. Participants in these trials ranged in age from 40 to 82. In both studies, the odds of developing Alzheimer's and other forms of dementia were about the same among patients taking statins and not taking statins.
