Blood pressure drugs 'lower risk of Alzheimer's'

Blood pressure drugs 'lower risk of Alzheimer's'
15th January 2010

A drug used to lower blood pressure could be more effective against Alzheimer's disease than previously understood, according to a team from the Boston University School of Medicine.

Those taking angiotensin receptor blockers (ARBs) were up to 50 per cent less likely to develop dementia than those taking other blood pressure drugs, while ARBs also protected against other deterioration among those who already have the disease when combined with another drug.

Rebecca Wood, chief executive of the Alzheimer's Research Trust, was happy to hear the news and is hopeful about the future.

She said: "This adds further weight to the adage that what is good for the heart is good for the head. It could be that ARBs protect brain cells from injury caused by damaged blood vessels, thought to have links to the development of dementia."

Ms Wood added that this new clue needs to inspire further in-depth trials to see how far ARBs can help protect against the condition.
