Treating hypertension in the elderly protects against dementia and cognitive decline, according to a study from Honolulu's Pacific Health Research Institute.

In fact, the study found that for each year an individual takes blood pressure medication, the risk of dementia decreases by about 3%.

"Hypertension treatment in the very old -- those ages 80 and older -- protects against stroke, heart disease and heart failure, and now we see that there is no harm -- and perhaps a benefit -- on cognitive function," concluded Dr.Rita Peila and her colleagues.said.

The investigators analyzed data from the long-term Honolulu-Asia Aging Study on Japanese-American men. They focused on 848 men (average age 77) who had been diagnosed with high blood pressure during mid-life. In 1991 and at regular yearly intervals through 1999, the men were assessed for dementia and cognitive decline.

Compared with men who were never treated for hypertension, the risk of developing dementia during the study period was as follows:

- 6% lower in those treated less than five years. - 48% lower in those treated from five to 12 years. - 60% lower in those treated more than 12 years. The demential risk for this last group was the risk in a control group of men with normal blood pressure.

The study appears in the journal, Stroke.
