The team of researchers from the University of Bristol have looked at whether drugs already being used to treat hypertension, particularly ones that specifically reduce the activity of a biochemical pathway, called the renin angiotensin system, might reduce the occurrence of Alzheimer's and another common type of dementia called vascular dementia.
The study, conducted with the support from North Bristol NHS Trust and published online in the Journal of Alzheimer's Disease, stems from work by one of the team's members, Dr Patrick Kehoe. Dr Kehoe, who is a Reader in Translational Dementia Research and co-leads the Dementia Research Group at Frenchay Hospital, Bristol, is a leading authority on the possible role of the renin angiotensin system in Alzheimer's.
This pathway is very important in blood pressure regulation and, for at least a decade, links between hypertension and dementia have been known but poorly understood.
In more recent years it has been shown that certain signals produced by this pathway contribute to a number of the damaging effects often seen in the brains of people with Alzheimer's. These include memory loss, lowered blood circulation in the brain, higher levels of brain inflammation and increased levels of brain cell death due to reduced oxygen circulation.
Dr Patrick Kehoe said: "Drugs that can prevent Alzheimer's occurring at all, or delaying its onset would have a substantial benefit on the lives of future sufferers, their families, as well as an overstretched health care system. Continue to read: sciencedaily.com
Sugar-free drinks may generate false security on tooth decay
Acidic flavourings and preservatives added to sugar-free beverages and confectionery may pose a ‘dental health risk’ to consumers who believe such products don’t cause tooth decay. Read more: beveragedaily.com
