The raison d'etre of this website is to provide you with hard scientific information which may help you make informed decisions in your quest for health (so far I have blogged concise summaries of over 1,500 scientific studies and have had three books published).

My research is mainly focused on the effects of cholesterol, saturated fat and statin drugs on health. If you know anyone who is worried about their cholesterol levels and heart disease, or has been told to take statin drugs you could send them a link to this website, and to my statin or cholesterol or heart disease books.

This study investigated the relationship between cholesterol levels and the risk of dementia. The study included 1,027 men who were followed for 26 years. Over the course of the study the men had their cholesterol levels measured on five occasions and were screened for dementia on two occasions.

The study found that  cholesterol levels in men with dementia and, in particular, those with Alzheimer disease had declined at least 15 years before the diagnosis and remained lower than cholesterol levels in men without dementia throughout that period.

Stewart concluded: "A decline in serum total cholesterol levels may be associated with early stages in the development of dementia".
