A blood pressure pill could slow down Alzheimers disease by improving flow of blood to parts of the brain linked to memory, research suggests.
Dutch research found that those given the pills for six months saw a 20 per cent increase in circulation of blood to the hippocampus.
Scientists said the findings suggest that the decrease in blood flow in patients with Alzheimer’s disease could be reversed.The study by Radboud University Medical Centre in Nijmegen, the Netherlands, involved 44 participants, half of which were given nilvadipine with half given a placebo for six months.
Study lead author Professor Jurgen Claassen, of Radboud University Medical Centre in Holland, said: "This high blood pressure treatment holds promise as it doesn't appear to decrease blood flow to the brain, which could cause more harm than benefit. Researchers said sample sizes were too small and follow-up time too short to reliably study the effects of this cerebral blood flow increase on structural brain measures and cognitive measures.
