A study has stated that cognitive decline in dementia can be slowed down by a class of drug used to lower blood pressure along with giving a boost to brain power.

Ireland Researchers had analysed 361 patients for cognitive decline and brainpower and the average age of these patients was 77 years. All these patients had been diagnosed of vascular dementia or Alzheimer's disease.

Of these patients, eight five per cent of the patients in the group were already on ACE inhibitors; the rest were not.

The impact was also seen by researchers on 30 patients, with an average age of 77 years, who were taking the drugs for the first time.

Dr James Pickett of the Alzheimer's Society said, "Any drug which halts cognitive decline is potentially exciting because it has the ability to radically improve quality of life."

This clearly indicates that cognitive decline was slower among patients who were consuming ACE inhibitors as compared to those who were not on the drugs stating that the blood pressure drugs help those who are prone to dementia in life.
