Older people taking certain types of blood pressure-lowering medication had better rates of memory recall, suggesting it could be used to slow memory decline. .
Researchers found that treating people over the age of 50 with angiotensin II receptor blockers, such as candesartan and irbesartan, as well as ACE inhibitors such Ramipril and Lisinopril, reduced cognitive impairment by 19 per cent. .
Each type of medication acts in a different way to reduce blood pressure, with some crossing the blood-brain barrier and impacting on cognitive function.
Older people taking certain types of blood pressure-lowering medication had better rates of memory recall, suggesting it could be used to slow memory decline.
Angiotensin-converting-enzyme (ACE) inhibitors, angiotensin II receptor blockers (ARBs), calcium channel blockers and diuretics are different classes of blood pressure-lowering medicines commonly used on patients.
He said this is the first to compare the potential impact over time of blood pressure lowering medicines that do and those that do not cross the blood-brain barrier.
They found that older adults taking blood pressure-lowering medicines that cross the blood-brain barrier had better memory recall for up to three years of follow-up compared to those taking medicines that do not cross the blood-brain barrier. .
Study co-author Dr Jean Ho, said this is the most powerful evidence to date linking ACE-inhibitors, and angiotensin receptor blockers to better memory. .
Researchers found that people over the age of 50s taking angiotensin II receptor blockers and ACE inhibitors reduced cognitive impairment by 19 per cent.
Persistent high blood pressure can increase your risk of a number of serious and potentially life-threatening conditions, such as:
