Alzheimer's risk 'cut' by beta blocker

COMMON blood pressure drugs taken by millions of people have been linked to a lower risk of Alzheimer's disease, researchers have said.
The brains of those who had taken blood pressure drugs, particularly a class known as beta blockers, showed fewer changes linked to Alzheimer's disease.
The researchers, who presented their findings at the American Academy of Neurology annual meeting in San Diego, examined the brains of 774 men after they had died, 610 of whom had been treated for high blood pressure.
It was found that the men who had received beta blockers as their only blood pressure medication had fewer abnormalities in their brains compared with those who had not been treated for their hypertension, or who had received other blood pressure drugs.
Those who had been given beta blockers in combination with other drugs also had fewer brain lesions and less shrinkage – changes linked to Alzheimer's – but not to the same extent as those who had used them alone. (© Daily Telegraph, london)
