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.

The objective of the study was to evaluate the association between the use of benzodiazepines and dementia. The study included 1,063 men and women, average age 78 years, who were followed for 15 years.
Benzodiazepines are a group of medications which have been used since the 1960s to treat anxiety, epileptic seizures, mania, alcohol withdrawal and sleeping problems.
The list below shows some of the different generic and brand names of benzodiazepines.
  • diazepam - Valium, Ducene, Antenex
  • oxazepam - Serepax, Murelax, Alepam
  • nitrazepam - Mogadon, Alodorm
  • temazepam - Euhypnos, Normison, Temaze
  • lorazepam - Ativan
  • flunitrazepam - Rohypnol, Hypnodorm
  • bromazepam - Lexotan
  • clonazepam - Rivotril

The study found that users of benzodiazepines had a 60% increased risk of dementia compared to non-users.
