A high blood pressure drug that costs just pennies could slow down and even reverse Alzheimer's disease، research suggests، as the Daily Mail said.
A study found patients who took the hypertension medication nilvadipine for six months had a 20 per cent increase in blood flow through the parts of their brains that control memory.
Nilvadipine increases cerebral blood flow by blocking calcium from entering arteries and causing them to relax.
This may allow more oxygen to reach and nourish the areas of the brain that regulate memory and learning.
Although the research is in its early stages، scientists believe nilvadipine could reverse the signs of Alzheimer's in certain regions of a patient's brain.
However، it is unclear whether this would lead to fewer dementia symptoms، which are incurable under existing treatments. The research was carried out at Radboud University in the Netherlands and was led by Professor Jurgen Claassen.
'Even though no medical treatment is without risk، getting treatment for high blood pressure could be important to maintain brain health in patients with Alzheimer's disease،' Professor Claassen said.
Importantly، nilvadipine boosted blood flow to a brain's 'learning centre' without diverting it away from other areas of the vital organ.
Professor Claassen added: '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.'
