Study: Viagra may reduce risk of Alzheimer’s disease

(CNN) - A popular erectile dysfunction drug may also reduce the risk of Alzheimer’s disease.

A study in the journal Neurology looked at the medical records of nearly 270,000 men.

They found that those taking Viagra were 18% less likely to develop Alzheimer’s disease.

The research did not uncover possible reasons and recommended additional research using both men and women.

Alzheimer’s is the most common form of dementia, affecting more than 6 million people in the United States aged 65 or older.
