Viagra Can Prevent Dementia?

Viagra, known as the blue pill has been used to overcome sexual problems in men. Viagra increases blood flow to the penis so make the sex organs in men get an erection.
Then, whether Viagra can also increase blood flow to other organs, such as the brain? Scientists will examine further the benefits of viagra for human brain.
So far a number of scientists believe, Viagra can prevent dementia, especially vascular dementia. The disease is caused by damage to the small blood vessels in the brain so that the blood flow to the brain is reduced. Akibatknya, there could be damage to the brain and cause memory impairment or memory. Usually begins with stroke.
To know the other benefits of these powerful drugs, scientists will examine tadalfil, which is the same type of drug as viagra. This Tadalfil can increase the blood flow to the brain, thus preventing vascular dementia.
For the latest research, tadalfil will be given to 50 participants over the age of 65 years. Participants are people who have problems with memory or memory.

The researchers will measure the blood flow to the brain before and after the drug is given. Participants will be given a drug with a low dose, and sometimes will be replaced with placebo. This is so that scientists can compare how much blood that reaches the brain because it was given medication and without medication.

Participants are not people who have been diagnosed with dementia. The trial of this drug is intended to prevent dementia.
Principal investigator of the St. George's, University of London, UK doctors Atticus Hainsworth said, many researchers are enthusiastic because it is still very little medicine for dementia.
"Tadalafil is a drug commonly used to increase blood flow to the penile tissues. Now we ask, whether tadalfil also can have the same function for other vital organs, such as brain? "Said Atticus.
Based on data from the World Health Organization (WHO), as many as 35.6 million people worldwide suffer from dementia and there are 7.7 million new cases every year. Patients with vascular dementia is quite a lot. Dementia can be characterized by a decrease in the ability to remember, ability to think, to the ability to perform daily activities.
