According to recent studies, viagra enhances blood flow to the brain and may help prevent dementia. Researchers at the University of Oxford discovered that in people who are more likely to develop the illness, the medication, commonly known as sildenafil, improves the function of brain blood arteries.
The study, according to experts, may revolutionize the prevention and treatment of vascular dementia, a condition in which there are now no effective treatments for decreased blood supply to the brain. “This is the first trial to show that sildenafil gets into the blood vessels in the brain in people with this condition, improving blood flow and how responsive these blood vessels are,” stated Dr. Alastair Webb, an associate professor at the Wolfson Centre for Prevention of Stroke and Dementia at Oxford.
The most prevalent cause of vascular dementia is chronic damage to the brain’s tiny blood arteries, which is linked to these two important variables.75 individuals with mild to moderate small artery disease who had previously suffered a mini stroke participated in the study, which was reported in Circulation Research. Over three weeks, cilostazol, a comparable medication, a placebo, and Viagra—a medication frequently used to treat erectile dysfunction—were given to each participant in a random order.
The researchers discovered that cilostazol and Viagra both reduced blood vessel resistance in the brain and enhanced blood flow in both big and small brain capillaries.
In addition, there were less adverse effects from Viagra than from cilostazol, especially in terms of diarrhea.
Larger-scale trials are required, according to the researchers, to validate these results and investigate sildenafil’s potential as a general preventive measure for vascular dementia.
The National Institute for Health and Care Research and the Wellcome Trust provided funding for the study.
