A study of 135 people over 65 and newly diagnosed with Alzheimer's disease in Utah has found that high blood pressure and a form of irregular heartbeat called atrial fibrillation may accelerate cognitive decline associated with Alzheimer's disease. The results of the study showed that those with high blood pressure at the time of their diagnosis showed a rate of memory loss twice as fast as those with normal blood pressure. Those with atrial fibrillation at the time of their diagnosis showed a rate of memory decline 75% faster than those with normal heartbeats. The researchers involved in the study are now looking at drugs aimed at lowering blood pressure and stabilising hearbeats to see how effective they are at staving off cognitive decline.
